NCERT Molecular Model Kit (Product Code: SCL-508/04) is a set of colour-coded plastic atoms and connecting bonds used to build three-dimensional chemical structures in school and college chemistry classes. Teachers and students use it as a chemistry teaching kit for organic models, from simple molecules to more complex structures, and every piece stores in a compartment box. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Molecular Model Kit Used For?

Teachers build methane, ethene and ethyne side by side so students can compare tetrahedral, planar and linear shapes, then move on to structural and geometrical isomers and the functional groups met in NCERT organic chemistry chapters. Because each element is identified by its colour, learners can check their own model against a structural formula and spot a wrong atom or a missing bond straight away.

For group work, give each team one compartment of atoms and a list of target molecules; at the end of the lesson the pieces come apart and go back into the box for the next class. Model-building is also a quick revision aid for hybridisation and bond angles before examinations, which is why the kit sits comfortably alongside the rest of a school’s chemistry lab equipment in India.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM (original equipment manufacturer) of the NCERT Molecular Model Kit. The kit is made at the company’s own licensed factory at Saha, Ambala, Haryana, India, and goes factory-direct to schools, colleges, dealers and importers rather than through a trading middleman. For vendor registration, institutions can record the company’s GSTIN 06AAECJ8618A1ZT and Legal Entity Identifier 3358004HRD1JIVXKYX49.

Replacement pieces and repeat class sets are handled by the manufacturer itself, so ask us whenever a set needs topping up. More about the company is on our company profile.

Frequently Asked Questions

What is included in the NCERT Molecular Model Kit?
The NCERT Molecular Model Kit contains colour-coded plastic atoms and connecting bonds, stored in a practical box with compartments. The exact piece count is not given in our current listing, so please contact us for the component list before ordering, especially if you plan to build larger molecules.

What does colour coded to the universal standard mean?
In the NCERT Molecular Model Kit, each element has its conventional colour, so a model built in one classroom reads the same way as the structures shown in textbooks and on wall charts. Students can identify every atom by colour alone while they build.

Which classes is the NCERT Molecular Model Kit suitable for?
The NCERT Molecular Model Kit is aimed at school and college level. It suits the organic chemistry topics taught in senior secondary NCERT classes and introductory college courses, and it handles both simple molecules and more advanced, complex structures.

Can the NCERT Molecular Model Kit models be taken apart and reused?
Yes. The atoms and bonds of the NCERT Molecular Model Kit connect securely and disconnect easily without hurting fingers, so the same pieces can be rebuilt into new molecules lesson after lesson and returned to the compartment box after class.

Is the kit safe for younger children?
The NCERT Molecular Model Kit contains small plastic parts, so younger children should use it only under adult supervision. Older students can assemble and dismantle models on their own, and teachers should count pieces back into the box at the end of each session.

Who manufactures the NCERT Molecular Model Kit?
The NCERT Molecular Model Kit is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab) as the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools and dealers buy it direct from the manufacturer, which also handles repeat orders and replacement pieces.

Can you supply kits for a whole class or for export?

Hand Operated Centrifugal Machine (Product Code: SCL-511/05) is a manually driven laboratory centrifuge used to separate two or more substances of different density in school and college labs. Its smooth-running, self-lubricating gearing lets an operator reach speeds of up to 3000 rpm by hand without difficulty, so this piece of chemistry lab equipment in India works with no mains power at all. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Hand Operated Centrifuge Used For?

In school chemistry practicals the machine separates a precipitate from its mother liquor during salt analysis, clears a turbid solution before a colour test, and shows how centrifugation splits cream from milk or sediment from muddy water. The gearing multiplies each turn of the handle, so a steady, comfortable pace brings the samples up to speed; ease off gradually and let the head stop on its own before lifting out the tubes.

Load tubes in opposite positions with equal volumes so the head stays balanced, and keep hands and loose sleeves clear while it turns. Because nothing needs plugging in, the machine can be moved between rooms or taken outdoors, which suits a new lab setup in a school where the power supply is intermittent; pair it with tubes, a rack and a Pasteur pipette for drawing off the clear layer.

OEM Manufacturer

Jain Scientific Equipments Private Limited, trading as ScienceLab, is the OEM (original equipment manufacturer) of the Hand Operated Centrifugal Machine. It is made and assembled at the company’s own licensed factory at Saha, Ambala, Haryana, India, rather than bought in from a trader, and supplied factory-direct to schools, colleges, dealers and importers in India and international markets.

If you need replacement parts or a repeat order later, ask us and the manufacturer handles it directly. Our company profile has more background on the company.

Related Chemistry Lab Equipment

Items that complete a hand-centrifuge station:

• Hand Centrifuge — another manual centrifuge from our Centrifuges range, worth comparing
• Centrifuge Tubes — tubes for holding the samples being separated
• Pipette, Pasteur — for lifting off the clear liquid after a spin
• Test Tube Stand Poly Lab — keeps tubes upright while samples are prepared and read

More apparatus is listed in our Chemistry Lab category.

Frequently Asked Questions

How fast can the Hand Operated Centrifugal Machine spin?
The Hand Operated Centrifugal Machine can reach speeds of up to 3000 rpm without difficulty, thanks to its gear ratio. The speed on any run depends on how quickly and steadily the handle is turned, so build up the pace gradually and slow down the same way.

Does the Hand Operated Centrifugal Machine need electricity?
No. The Hand Operated Centrifugal Machine is operated manually by hand, so it needs no mains supply and works in any classroom, field station or outdoor demonstration where electricity is unavailable or unreliable.

What maintenance does it need?
Very little. The Hand Operated Centrifugal Machine has smooth-running, self-lubricating gearing and is virtually maintenance-free. Wipe off any spills after use, store it dry, and check that the handle turns smoothly before each practical.

Which tubes does it take, and how many?
Tube size and the number of positions on the Hand Operated Centrifugal Machine are not given in our current listing. Please contact us for the head configuration before ordering, and we will confirm which tubes it accepts.

Who manufactures the Hand Operated Centrifugal Machine?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Hand Operated Centrifugal Machine as the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Buyers deal directly with the manufacturer for quotations, spare parts and repeat orders.

How is it different from the Hand Centrifuge?
Both are manual centrifuges. The Hand Operated Centrifugal Machine is described by its self-lubricating geared drive that reaches up to 3000 rpm, while the Hand Centrifuge is a separate model; compare both listings or ask us which suits your practical.

Can schools order in quantity?
Yes. Share the number of Hand Operated Centrifugal Machine units required and the delivery location in India or abroad, and the manufacturer will prepare a school, tender or dealer quotation for you.

Weight Box (Product Code: SCL-513/06) is a boxed set of 9 metal weights from 1 g to 100 g used to measure mass on a two-pan beam balance in school and college laboratories. Students use it with a chemical balance in Indian labs to weigh salts and learn systematic weighing, and the polished wooden box keeps every piece in its place. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Weight Box Used For?

On a two-pan chemical or physical balance, the object goes on one pan and weights are added to the other from largest to smallest until the beam balances; the weights on the pan are then added up to give the mass. The duplicate 2 g and 20 g pieces let students build up whole-gram values step by step, which is how beam-balance technique is still taught before digital balances. Typical tasks include weighing salts for standard solutions, finding the mass of a crucible before and after heating, and density experiments in physics.

Always lift weights with forceps rather than fingers, because skin oils and moisture gradually change their mass, and return each piece to the box as soon as it leaves the pan. If a practical needs values below 1 g, combine this set with fractional weights and a rider. Kept this way, a weight box remains dependable chemistry lab equipment in India for any school that teaches beam-balance weighing.

What to Specify When Ordering

• Which finish you need — the listing describes chrome-plated brass, nickel-plated brass and bronze weights.
• Whether you also need sub-gram weights, since the listed pieces start at 1 g while the stated range begins at 1 mg.
• How many weight boxes you need, usually one per balance or bench group.
• Any balances or forceps that should be quoted together with the weights.

OEM Manufacturer

The Weight Box is manufactured by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is the OEM (original equipment manufacturer) of this set. It is made at the company’s own licensed factory at Saha, Ambala, Haryana, India, and goes factory-direct to schools, colleges, dealers and importers instead of passing through a trader.

If a piece goes missing or a department wants a repeat order, ask us and the manufacturer arranges it. More about the company is on our company profile.

• Analytical Weight Box — an alternative weight box in our Chemistry Lab Equipment range
• Forceps — for handling weights without touching them

See more in our Chemistry Lab category.

Frequently Asked Questions

Which weights are in the Weight Box?
The Weight Box holds nine pieces: one each of 1 g, 5 g, 10 g, 50 g and 100 g, plus two each of 2 g and 20 g. The duplicate pieces let students make up intermediate whole-gram values on a two-pan balance.

Does the Weight Box include milligram weights?
The Weight Box range is stated as 1 mg to 100 g, but the listed pieces start at 1 g. Please confirm with us whether fractional weights are included in your order; sub-gram pieces are also available as the Fractional Weight With Rider.

What are the Weight Box weights made of?
Our listing for the Weight Box describes the weights as chrome-plated brass, as brass with a nickel-plated finish, and as bronze. We confirm the material and finish of current production in each quotation, so state any preference when you enquire.

What tolerance or accuracy class do the weights meet?
A tolerance class for the Weight Box is not stated in our current documentation. For accuracy details or calibration certificate availability, contact us before ordering and mention the balance you intend to use.

Why should the weights be handled with forceps?
Fingerprints leave oil and moisture that slowly change a weight’s mass and can mark its surface, so pieces from the Weight Box should always be lifted with forceps and returned to their places in the wooden box after use.

Who manufactures the Weight Box?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Weight Box as the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges and dealers order it directly from the manufacturer, which also handles repeat orders.

Can you quote for a full class set?

Electric Water Bath (Product Code: SCL-515/07) is a double-walled, stirred laboratory water bath used to hold samples at a steady set temperature between ambient and 100 °C in chemistry and life-science labs. Temperature is controlled by a mercury contact thermometer and relay with a listed sensitivity of 0.1 °C, and glass windows on two opposite sides let users watch the contents from the side. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Stirred Electric Water Bath Used For?

A thermostatic bath like this keeps reaction mixtures, reagent bottles and sample tubes at a fixed temperature for as long as an experiment needs — for example incubating enzyme tests, warming solutions before analysis, or studying how reaction rate changes with temperature. The stirrer circulates the water so every sample position sits at the same temperature rather than running hotter near the heater. It is a practical addition to chemistry lab equipment in India for colleges running temperature-dependent practicals.

Set the contact thermometer to the working temperature, fill the bath so the water covers the samples, and start the stirrer before heating so the relay responds to an even reading. Handle the mercury contact thermometer with care, as it is glass, and top up with distilled water to limit scale on the stainless-steel inner wall.

OEM Manufacturer

The Electric Water Bath SCL-515/07 is built by Jain Scientific Equipments Private Limited, which trades as ScienceLab, at its own licensed factory at Saha, Ambala, Haryana, India. As the original equipment manufacturer, ScienceLab supplies the bath factory-direct rather than through a trader, and requests for spare parts such as a contact thermometer, relay or stirrer are handled by the manufacturer itself — ask us.

Fractional Weight With Rider (Product Code: SCL-517/08) is a set of small weights and a rider used to make the final, finest additions of mass when balancing a sample on a laboratory beam balance. Students and lab assistants reach for it once the larger weights from a weight box are on the pan, and the pieces are provided in a plastic case. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Key Details

What Is the Fractional Weight With Rider Used For?

A weighing practical starts with the object on one pan and the larger weights added to the other until the pointer shows that only a small difference remains. That remaining difference is made up with the fractional weights, and on a balance with a graduated beam the rider is then lifted onto the beam and moved along it until the pointer settles at the centre. Students learn to think of every reading as whole weights plus a small, measured correction.

Small weights are easily affected by moisture and grease from fingers, so pick them up with forceps, arrest the beam before adding or removing any piece, and put each weight back in its own place in the plastic case. Keeping the case closed between uses protects the pieces from dust and stops them going missing, which matters when one set is shared by several batches using a chemical balance in an Indian school or college lab.

OEM Manufacturer

The Fractional Weight With Rider is manufactured by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is the OEM (original equipment manufacturer) for this weighing accessory. The company is incorporated under CIN U29309HR2020PTC087597 and makes it at its own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414).

Sets go factory-direct to schools, colleges, dealers and importers, and replacement pieces or repeat orders are arranged by the manufacturer — just ask us. See the ScienceLab company profile for more.

Related Chemistry Lab Equipment

Fractional weights are one part of a complete weighing set-up. Buyers usually order them with:

• Forceps (Tweezers) — for lifting small weights without touching them
• Analytical Weight Box — a boxed weight set for more demanding work

Browse the complete Chemistry Lab category for other practical apparatus.

Frequently Asked Questions

What does the rider in the Fractional Weight With Rider do?
The rider adds a very small amount of mass by sitting on the graduated beam of a balance instead of on the pan. In the Fractional Weight With Rider it is used for the final fine adjustment, so tell us your balance model to confirm it suits your beam.

Which weight values are in the case?
The denominations in the Fractional Weight With Rider case are not listed on this page. Please ask through our contact page and we will confirm the current contents before you order, so you can match them to your weight box.

How is the Fractional Weight With Rider packed?
The Fractional Weight With Rider is provided in a plastic case, which keeps the small pieces together, protects them from dust and makes it easy to check at the end of a practical that nothing has gone missing.

How should the fractional weights be cleaned and stored?
Handle the Fractional Weight With Rider pieces only with forceps and wipe them with a clean, dry, lint-free cloth if needed. Avoid water, solvents and chemical fumes, and always return every piece to the plastic case after the practical.

Asbestos Sheet Plain (Product Code: SCL-519/09) is a flat, square bench sheet used as a base under burners, tripods and hot apparatus during heating work in school and college laboratories. Chemistry teachers and lab technicians lay the 2 ft x 2 ft, 6 mm thick sheet on ordinary benches to keep flame, hot metal and spills off the bench top. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Asbestos Sheet Used For?

In a heating practical the sheet goes down first, and the tripod stand, wire gauze and burner are arranged on top of it so the whole set-up stands on one flat, level surface. Its plain face is also a resting place for a hot crucible or beaker lifted off the tripod with crucible tongs, keeping hot glassware off wooden or laminated benches. Giving every workstation the same square base lets a teacher see at a glance whether each group has kept its flame and hot apparatus inside its own area.

Keep the sheet flat and supported over its full area, and do not cut, drill, sand or break it, because damaging the surface can release dust. Clean it with a lightly damp cloth rather than brushing it dry, let it dry before the next session, and withdraw any sheet that is cracked, chipped or crumbling at the edges, disposing of it according to your local rules.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, sources and supplies the Asbestos Sheet Plain alongside the burners, tripods and other heating apparatus in its Chemistry Lab range. Because rules on this type of material vary, ask us to confirm its exact composition before you order.

Institutions and dealers in India and international markets can buy it together with the rest of their lab list on one quotation. More about the company is on our company profile.

Related Chemistry Lab Equipment

A bench sheet is normally part of a complete heating station. These items are used on or around it:

• Tripod Stand 200mm — stands on the sheet and holds the vessel above the flame
• Gauze Wire — rests on the tripod and spreads the flame under beakers and flasks
• Bunsen Burner — the usual heat source placed on the sheet
• Rubber Pipe For Bunsen Burner — connects the burner to the gas tap
• Crucible Tong — for moving hot crucibles onto the sheet to cool

More heating and general apparatus is listed in the Chemistry Lab category.

Frequently Asked Questions

What size is the Asbestos Sheet Plain?
The Asbestos Sheet Plain is a square sheet measuring 2 ft x 2 ft, with a thickness of 6 mm and a plain pattern, sized to sit under a burner and tripod as one flat heating base on a laboratory bench.

What material is the Asbestos Sheet Plain made of?
The Asbestos Sheet Plain is catalogued under that name, and no further composition details are listed. Rules on asbestos-containing materials differ between institutions and countries, so please confirm the exact composition with us through our contact page before ordering, especially for export.

Can the sheet be cut to fit a smaller bench?
We advise against cutting, drilling or sanding the Asbestos Sheet Plain, because damaging the surface can release dust. Tell us your bench dimensions instead, and we will advise on the options before you order.

Can the sheet be put directly over a flame?
The Asbestos Sheet Plain is intended as a flat base on the bench, not as a heating surface over a flame. To heat a beaker or flask, stand a tripod with wire gauze on the sheet and heat the vessel on the gauze.

How should the Asbestos Sheet Plain be cleaned?
Wipe the Asbestos Sheet Plain with a lightly damp cloth rather than brushing it dry, avoid abrasive pads, and let it dry fully before the next practical. Withdraw any sheet that is cracked, chipped or crumbling and dispose of it according to local rules.

Who supplies the Asbestos Sheet Plain?
The Asbestos Sheet Plain is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India. It can be quoted together with burners, tripods, gauzes and tubing, so a complete heating station comes from one supplier.

Funnel (Product Code: SCL-523/011) is a long-stem laboratory funnel moulded in clear polypropylene, used for gravity filtration and for pouring liquids into narrow-necked flasks without spills in school and college labs. Its 60° cone, smooth walls and external ribs that prevent air lock keep liquid moving, and it can be steam autoclaved. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Polypropylene Funnel Used For?

For filtration, a circle of filter paper is folded into a cone, opened out and seated in the funnel; the 60° cone lets the paper lie against the smooth wall so the liquid passes through the paper rather than running down the sides. The long stem fills with filtrate as the work proceeds, which helps draw the liquid through, and the external ribs keep a small air gap in the neck of a conical flask so the receiver can vent. The same funnel is handy for refilling reagent bottles and for pouring solutions into volumetric flasks during titration work.

Being polypropylene, it survives the knocks of a busy practical room far better than glass, which is why schools add it to their lab plastic ware alongside beakers and bottles, but it should not be placed over a flame or on a hot plate. Rinse it straight after use, clean with warm water, a mild detergent and a soft brush, and avoid abrasive powders. Where sterile handling is needed, for example in microbiology classes, steam autoclave it before use.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the OEM (original equipment manufacturer) of this polypropylene Funnel. It is produced at the company’s own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers rather than through a trading intermediary.

Repeat class orders are handled by the manufacturer itself, so ask us whenever your stock of funnels needs topping up. Read more on the ScienceLab company profile.

Related Chemistry Lab Equipment

These items are commonly ordered for the same filtration or transfer set-up:

• Filter Paper — folded into the cone for gravity filtration
• Funnel Holder — supports the funnel above the receiving vessel
• Conical Flask — a common receiver for the filtrate
• Beaker, Polypropylene — holds the mixture before it is poured
• Glass Funnel — an alternative where glass is preferred

The full Chemistry Lab category lists further apparatus for practical classes.

Frequently Asked Questions

What is the Funnel made of?
The Funnel (SCL-523/011) is moulded in polypropylene, a tough plastic, and the body is clear so the liquid level and the filter paper can be seen during use. It withstands the knocks of a practical room better than glass.

Why does the 60 degree cone angle matter?
The Funnel has a 60° cone, which matches a filter paper folded into quarters, so the paper sits evenly against the smooth wall and liquid passes through the paper instead of running down the sides.

Can the Funnel be sterilised?
Yes. The polypropylene Funnel can be steam autoclaved, which makes it suitable for microbiology and biology practicals as well as chemistry. Follow the cycle your autoclave recommends for polypropylene labware, and ask us if you need guidance.

What do the external ribs do?
The external ribs on the Funnel prevent air lock. They leave a small gap where the stem rests in the neck of the receiving flask, so air can escape and the filtrate keeps flowing instead of stalling.

Which diameters are available?
Sizes for the Funnel (SCL-523/011) are not listed on this page. Please enquire through our contact page with the diameter or capacity you need, and we will confirm what is currently available before quoting.

Who manufactures the Funnel?

Rubber Pipe For Bunsen Burner (Product Code: SCL-527/013) is neoprene gas tubing with reinforced ends, used to connect a Bunsen burner securely to the gas tap in school and college laboratories. It suits natural gas and LPG burners and comes in 600 mm pre-cut lengths with an 8 mm bore. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, among the chemistry consumables it provides to labs in India and abroad.

Specifications

What Is the Bunsen Burner Rubber Pipe Used For?

Push one reinforced end fully over the gas inlet of the burner and the other over the nozzle of the bench tap, making sure each end grips firmly. Lay the tubing so it does not pass over the flame, the tripod or any hot surface, and check the joints for leaks with a little soap solution before the first lighting of the day. At the end of the practical, close the gas tap first and let the burner go out, rather than pulling the tubing off a live supply.

Tubing ages with use and heat, so it is one of the lab consumables a school should inspect and renew regularly. Look for cracks, hardening, a sticky surface or loose ends before each session, and replace any length that shows these signs. Neoprene outlasts natural rubber tubing, which means fewer changes over a school year, but a regular check remains part of good gas safety.

What to Specify When Ordering

• The number of 600 mm lengths — usually one per burner, plus spares for replacement.
• That the 8 mm bore suits the nozzles on your gas taps and burners.
• Whether your burners run on natural gas or LPG; the tubing suits both.
• Any burners, lighters or tripods to be quoted together with the tubing.

Supplier

Jain Scientific Equipments Private Limited trades as ScienceLab from Ambala, Haryana, and supplies this neoprene tubing alongside the burners and heating accessories in its Chemistry Lab range. For vendor registration, the supplying company’s GSTIN is 06AAECJ8618A1ZT, and export orders are handled under Importer-Exporter Code AAECJ8618A issued by the DGFT.

Schools, colleges and dealers in India and international markets can include the tubing on one quotation with their burners. See our company profile for more about the company.

The Rubber Pipe For Bunsen Burner is suitable for both natural gas and LPG burners, so the same neoprene tubing can be used whichever gas supply your laboratory benches are fitted with.

What are the bore and length?
The Rubber Pipe For Bunsen Burner has an 8 mm bore and comes in 600 mm pre-cut lengths. Fit depends on the outer size of your gas tap and burner nozzles, so share those details with us if you are unsure.

Why neoprene rather than natural rubber?
The Rubber Pipe For Bunsen Burner is neoprene tubing, which lasts longer than natural rubber tubing, so each length needs replacing less often over a school year. Inspecting it before use is still part of safe gas practice.

Can I cut a length shorter?
We recommend using each Rubber Pipe For Bunsen Burner length as supplied, because cutting it removes one of the reinforced ends that give the secure connection to the burner or the gas tap.

How often should the tubing be replaced?
There is no fixed interval for the Rubber Pipe For Bunsen Burner. Inspect each length before every session, and replace it as soon as it is cracked, hardened, sticky or loose on the nozzle.

Who supplies the Rubber Pipe For Bunsen Burner?
The Rubber Pipe For Bunsen Burner is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India. It can be quoted with burners, lighters and tripods, so a school’s whole gas-burner station comes from one supplier.
