Rubber Stoppers without Holes Of Different Diameters (Product Code: SCI-204/024) are solid, round rubber stoppers used to close test tubes, small flasks and bottles in school, college and research laboratories. Having no bore, they simply shut the opening, and they come in bottom diameters of 11 mm, 13 mm, 14 mm and 15 mm for storing, shaking and protecting samples. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India serving schools and institutions.

Specifications

What Are Solid Rubber Stoppers Used For?

Solid stoppers do the quiet jobs of a practical class. Students stopper a test tube before shaking it to dissolve a solid or compare solubility, close a tube of collected gas until it is ready for the splint test, and seal small reagent or sample bottles so that dust stays out and evaporation is reduced. They also blank off a spare neck while apparatus is being assembled, which is why technicians keep a box of each size in the preparation room.

Never close a tube or flask with a solid stopper while it is being heated or while a reaction is still giving off gas: pressure builds up and can push the stopper out or crack the glass. Press the stopper in with a slight twist rather than a hard push, and ease it out the same way. If a set-up later needs a tube through the stopper, a hole can be bored with a wetted cork borer.

What to Specify When Ordering

• Bottom diameter(s): 11 mm, 13 mm, 14 mm or 15 mm.
• Quantity of each size for every lab or bench.
• The glassware to be closed, so sizes can be checked against its neck.
• Whether the one-hole version is also needed for delivery tubes and thermometers.

Creek Laboratory (Product Code: SCI-659/026) is a metal laboratory jack used to raise, lower and hold hot plates, burners, baths and glassware at a set height on the bench in school and college laboratories. Its knob-operated scissor mechanism gives quick, easy and accurate height adjustment, and the listing states that it takes loads over 25 kg. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM laboratory equipment manufacturer in India, at its own factory in Ambala.

Specifications

What Is the Laboratory Jack Used For?

A lab jack replaces the stack of wooden blocks that many benches once relied on. With a flask clamped on a retort stand, the jack brings a hot plate, burner or bath up to meet it and, just as importantly, drops the heat away quickly if a mixture boils too hard. When colleges assemble laboratory distillation apparatus, the jack lets the heat source be adjusted without loosening a single clamp, and in physics work it lifts glassware or small apparatus into line with other equipment.

Stand the jack on a level bench and centre the load on the platform before raising it. Turn the knob smoothly, and support glassware with clamps rather than relying on the jack alone to hold it upright. Stay within the listed load, wipe up spills straight away and keep the scissor joints clean and dry; the powder coating on mild steel jacks lasts longer when acids are not left standing on it.

What to Specify When Ordering

• Construction: stainless steel or powder-coated mild steel.
• Platform size: the catalogue lists the tile as 100 x 10 mm, so confirm it against the base of your hot plate or bath.
• The heaviest item the jack will carry (listed for loads over 25 kg).
• The number of jacks needed per laboratory.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer of this laboratory jack and produces it at its own licensed factory at Saha, Ambala, Haryana. The jack reaches schools, colleges, dealers and importers factory-direct rather than through a trading chain, so questions about construction, replacement knobs or repeat orders go straight to the maker — just ask us. Learn more on the ScienceLab company profile.

Related Laboratory Equipment

A jack is most useful alongside the heat sources and supports it positions:

• Glass-Ceramic Heating Plate — a heat source to raise and lower on the jack.
• Alcohol Lamp 150 ml — a small burner that can be set at the right height under a flask.
• Laboratory Stand with Accessories — clamps the glassware while the jack moves the heat source.
• Distillation Pot with Side Tube — a distillation flask for set-ups where heat needs fine adjustment.
• Laboratory Jack — another lab jack listing in the Laboratory Instruments range.

See the full Laboratory Equipment category for more bench apparatus.

Spoons for Burning (Product Code: SCI-291/027) is a deflagrating (combustion) spoon — a small hemispherical cup on a long wire handle — used to hold, ignite and lower small amounts of a substance into a jar of gas in chemistry laboratories. A standard piece of chemistry lab equipment in India, it is used for demonstrations of burning elements in air and in oxygen, with the long handle keeping hands well away from the flame. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Deflagrating Spoon Used For?

The spoon's classic job is to compare how substances burn in air and in pure oxygen. A small piece of the solid is placed in the cup, warmed in a lamp or burner flame until it catches, then lowered into a gas jar of oxygen, where the flame brightens noticeably. After the burn, students add a little water to the jar and test it with indicator to decide whether the oxide formed is acidic or basic. It works hand in hand with the gas collection apparatus in India's school chemistry labs, where the oxygen is prepared first.

Use only a very small quantity of substance, wear eye protection and keep a gas jar cover ready to close the jar once the sample has burned. Substances that give irritating fumes, such as sulphur, should be burned in a fume cupboard or a well-ventilated room. Rest the hot spoon on a heat-resistant mat and, once it has cooled, scrape the residue out of the cup so that it does not react with the next sample.

What to Specify When Ordering

• Quantity: one per demonstration bench or one per student group.
• Wire length and cup diameter, to be confirmed against the listed 3000 mm and 2.5 mm.
• Whether gas jars, covers or a lamp should be quoted on the same order.

OEM Manufacturer

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM that makes Spoons for Burning at its own licensed factory in Saha, Ambala, Haryana, India. Buying from the manufacturer instead of a reseller means quotations, repeat orders and any queries about the spoon's dimensions are handled at source. Schools, colleges, dealers and importers are all supplied factory-direct; the ScienceLab company profile has more background.

Related Laboratory Equipment

A combustion demonstration needs a few more pieces alongside the spoon:

• Deflagrating Spoon — an alternative combustion spoon in the Chemistry Lab Equipment range.
• Gas Jar, Glass — the jar of oxygen or air into which the burning sample is lowered.
• Gas Jar Cover — closes the jar before and after the burn.
• Alcohol Lamp 150 ml — a flame for igniting the sample in the cup.

Spoons for Substances (Product Code: SCI-859/028) is a stainless steel laboratory spoon used to scoop, portion and transfer solid chemicals and powders in school, college and research laboratories. At 130 mm total length with a polished, rust-resistant finish, it reaches into reagent jars, wipes clean quickly and suits any school laboratory setup in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Laboratory Spoon Used For?

Most practicals start with getting the right amount of a solid out of its bottle. The spoon lifts crystals or powder from a stock jar onto a watch glass or weighing paper, adds a solid reactant to a test tube a little at a time, and moves ground samples from a mortar into a dish. When students weigh reagents on a chemical balance in an Indian school lab, a clean steel spoon lets them add or remove tiny amounts until the reading is right.

Keep one spoon per reagent where possible, or wipe, rinse and dry it between substances so that traces do not contaminate the next bottle. Never return surplus solid to the stock jar, and do not use this spoon to heat substances in a flame — that is the job of a deflagrating spoon. Where a reagent should be kept off metal altogether, a porcelain spoon is the better tool.

OEM Manufacturer

Jain Scientific Equipments Private Limited, known by its trade name ScienceLab, is the OEM behind Spoons for Substances and produces the spoon at its own licensed factory in Saha, Ambala, Haryana, India. A school equipping several benches can order the spoons with other small metal lab ware on one factory-direct quotation, and repeat orders go straight back to the maker; just ask us. More details are on the ScienceLab company profile.

Related Laboratory Equipment

Measuring out solids usually involves these companion items:

• Spoon- shoulder — a porcelain spoon for reagents best kept away from metal.
• Spatula, Spoon End — a spatula with a spoon-shaped end for smaller portions.
• Semi-Analytical Scales with Weighing Stone Boxes — for weighing the portions you transfer.
• Watch Glass — a shallow glass dish to hold weighed solids.

More small tools and glassware are in the Laboratory Equipment category.

Frequently Asked Questions

What is Spoons for Substances made of?
Spoons for Substances is made of stainless steel with a polished, silver finish. The steel is described as chemical resistant and rust resistant, so the spoon keeps its clean surface after repeated washing between reagents in school and college laboratories.

How long is the spoon?
Spoons for Substances has a total length of 130 mm. That length helps it reach into reagent jars and stock bottles while staying short enough to control small scoops when adding a solid to a balance pan or a test tube.

Can it be used to heat substances in a flame?
No, Spoons for Substances is intended for scooping and transferring solids, not for heating them in a flame. For burning small samples in a gas jar, use a deflagrating spoon such as Spoons for Burning, which carries its cup on a long wire handle.

How should the spoon be cleaned?
Clean Spoons for Substances by tapping off loose powder, rinsing it with water and drying it fully before the next reagent. Its polished stainless steel surface shows residues clearly, which helps students avoid cross-contaminating chemicals.

Who manufactures Spoons for Substances?
Jain Scientific Equipments Pvt Ltd (ScienceLab) is the OEM for Spoons for Substances and makes it at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, laboratories, dealers and importers order it factory-direct, with the quotation prepared by the manufacturer itself.

Can it be ordered in class sets or bulk?

Ceramic Mesh Square (Product Code: SCI-659/030) is a square wire gauze with a ceramic circle in the centre, used to carry beakers, flasks and evaporating dishes over a burner or spirit lamp flame on a tripod, with the ceramic disc softening the heat that reaches the glass. It measures 125 x 125 mm, combines metal wire with ceramic and has smooth rolled edges — a routine purchase for benches that need wire gauze for lab work in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Ceramic Wire Gauze Used For?

Almost every heating practical in a school syllabus passes through a gauze. Students warm water in a beaker to dissolve a solute faster, evaporate a salt solution in a porcelain dish until crystals appear, and bring a flask of water to the boil for boiling-point or latent-heat work. On the tripod stand used in labs across India, the square lies flat across the frame and gives each vessel a steady, supported base.

Adjust the flame so that its hottest part reaches just beneath the ceramic circle rather than the bare wire. After heating, lift the gauze by its rolled edge with tongs, because the ceramic stays hot long after the flame is turned off, and never drip cold water onto a hot square. Stack spare squares flat in a drawer instead of hanging them on hooks, so the ceramic disc is not knocked or chipped.

OEM Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, the OEM that produces the Ceramic Mesh Square at its own licensed factory in Saha, Ambala, Haryana. The square is supplied as a finished item, net and ceramic circle together, and schools, colleges, dealers and importers order it direct from the maker. The company is a registered MSME whose major activity is manufacturing (Udyam UDYAM-HR-01-0003714), and export consignments are shipped under Importer-Exporter Code AAECJ8618A (DGFT). See the ScienceLab company profile for more.

• Chemical Beaker 250 ml — a typical vessel heated on the gauze.
• Ceramic Mesh — another ceramic-centre gauze listing.

Explore the complete Laboratory Equipment category for more heating accessories.

Frequently Asked Questions

What size is the Ceramic Mesh Square?
The Ceramic Mesh Square measures 125 x 125 mm. Its square format rests across a laboratory tripod to give beakers, flasks and evaporating dishes a flat, supported base over the flame; check the frame size of your tripod if you use an unusual model.

What does the ceramic circle do?
The ceramic circle in the centre of the Ceramic Mesh Square receives the direct flame and passes the heat on more gently to the base of the vessel above. This softens local hot spots that could otherwise crack glassware during heating.

Are the edges safe to handle?
Yes, the Ceramic Mesh Square has wire edges that are rolled smooth, so there are no loose, sharp wire ends to catch fingers or gloves. After heating, still lift it with tongs, since both the metal and the ceramic stay hot for some time.

Can it be used with a spirit lamp?
Yes. The Ceramic Mesh Square works with a spirit lamp as well as a gas burner, as long as it rests on a tripod of suitable height so the flame reaches the ceramic circle. A spirit lamp gives a smaller flame, so heating simply takes longer.

Who manufactures the Ceramic Mesh Square?
The Ceramic Mesh Square is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory at Saha, Ambala, Haryana, India. Schools and dealers buy it factory-direct, and repeat orders for extra squares are handled by the same manufacturer.

What does a quotation need?
A quotation for the Ceramic Mesh Square needs the quantity, for example one per tripod, your delivery location, and any tripods, burners or beakers to be quoted with it. Send the list through the contact page and the manufacturer will reply directly.

Cork Drills (Product Code: SCI-661/031) are hand-operated steel cork borers used to cut clean holes in corks and rubber stoppers so that glass tubes, thermometers and delivery tubes can be fitted into laboratory apparatus. The set covers 3 sizes from 5 mm to 7.5 mm in polished, chemical-resistant steel, a practical addition to lab equipment accessories in India. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Are Cork Borers Used For?

Building apparatus from stock parts nearly always means making a hole. With a cork borer, a solid stopper becomes the top of a gas generator carrying a delivery tube, a flask closure that holds a thermometer for distillation, or the head of a simple wash bottle. Choose a borer slightly smaller than the outside of the glass tube, so the finished hole grips the tube firmly. Schools and colleges buying lab equipment in India usually keep at least one set in the preparation room for this reason.

Mark the centre of the stopper, wet the cutting edge with water or glycerine when boring rubber, and press with a steady turning motion rather than brute force. Bore from the narrow end towards the wide end, keeping the borer upright for a straight hole. Clear the cut plug from the borer before the next hole, wipe the steel dry and store the borers so their cutting edges do not knock together.

What to Specify When Ordering

• The number of sets required (each covers 3 sizes, 5 mm to 7.5 mm).
• The outside diameters of the glass tubes or thermometers you will fit, so suitable sizes can be confirmed.
• Whether stoppers, corks or a borer sharpener should be quoted too.

OEM Manufacturer

Cork Drills are produced by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is the OEM and makes them at its own licensed factory at Saha, Ambala, Haryana, India. Because the borers come from the manufacturer rather than a stockist, laboratories get one point of contact for quotations, extra sets and later top-ups — just ask us. Schools, colleges, dealers and importers are served factory-direct; details are on the ScienceLab company profile.

Related Laboratory Equipment

Boring a stopper is one step; these items complete the job:

• Cork Borer Sharpener — restores the cutting edge after repeated use.
• Rubber Stoppers without Holes Of Different Diameters — solid stoppers ready for boring.
• Cork Stoppers — natural corks to bore for tubes and thermometers.
• Glass Pipes of Different Diameters — tubing to pass through the new hole.

More bench tools are listed in the Laboratory Equipment category.

Frequently Asked Questions

Which sizes are included in Cork Drills?
Cork Drills come in 3 sizes spanning 5 mm to 7.5 mm. Choose the size slightly smaller than the outside diameter of the glass tube or thermometer you want to fit, so the finished hole grips it firmly. Ask us if you need each borer's size confirmed.

Can Cork Drills bore rubber stoppers as well as corks?
Yes, Cork Drills can bore both corks and rubber stoppers. For rubber, wet the steel cutting edge with water or glycerine and turn it steadily while pressing lightly; this gives a cleaner hole than forcing the borer straight through.

What are they made of?
Cork Drills are made of steel with a polished, silver finish and are described as chemical resistant. Wipe them clean and dry after boring to keep the polished surface and the cutting edges in good order between practical sessions.

Who manufactures Cork Drills?
Cork Drills are manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), acting as OEM, at its own licensed factory in Saha, Ambala, Haryana, India. The company sells them factory-direct to schools, colleges, dealers and importers, so quotations come from the maker itself.

How do I keep the borers sharp?
Keep Cork Drills sharp by storing them so the cutting edges do not knock together and by honing them when holes start to tear rather than cut cleanly. A cork borer sharpener, listed separately by ScienceLab, restores the edge.

What should a quotation request include?
To get a quotation for Cork Drills, send the number of sets, your delivery location and any stoppers, corks or glass tubing to be priced together through the contact page. Bulk and export enquiries for India and international markets are welcome.

Clamp Bar Clamps (Counter Clamp) (Product Code: SCI-635/032) is a metal burette clamp used to hold a burette steady and upright during titrations in school and college chemistry laboratories. It is die-pressed from thick mild steel sheet with self-closing jaws whose ends are covered with rubber, and it opens to a maximum space of 22 mm — a practical burette clamp for India's lab benches. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Burette Clamp Used For?

In a titration the burette must stay vertical above the conical flask while the student swirls the flask and watches for the colour change. This clamp's self-closing jaws grip the burette without a thumb-screw, so it can be slipped out for refilling and dropped back into place in moments, while the rubber-covered ends stop the glass slipping or being scratched. It suits any class running a titration kit in school labs across India, from simple acid-alkali work to redox titrations.

Before starting, check that the burette hangs straight by sighting it against a vertical edge, and read the scale at eye level rather than tilting the clamp. Take the burette out to refill it below eye level, then return it to the jaws. Measure your burette's outside diameter against the 22 mm maximum opening before ordering, and wipe acid or alkali drips off the steel so the clamp keeps working smoothly.

OEM Manufacturer

The Clamp Bar Clamps (Counter Clamp) is made by Jain Scientific Equipments Private Limited, trading as ScienceLab, as the original equipment manufacturer at its own licensed factory at Saha, Ambala, Haryana. Laboratories deal directly with the factory that makes the clamp, and it is supplied to schools, colleges, dealers and importers without a middleman. For replacement clamps or extra titration stations, ask us; the ScienceLab company profile explains more about the company.

Frequently Asked Questions

What is the Clamp Bar Clamps (Counter Clamp)?
Clamp Bar Clamps (Counter Clamp) is ScienceLab's metal burette clamp: a die-pressed mild steel clamp with self-closing, rubber-covered jaws that hold a burette upright for titration. The product name follows our catalogue listing; in use it works as a self-closing burette holder.

What size burette will it hold?
The jaws of the Clamp Bar Clamps (Counter Clamp) open to a maximum space of 22 mm. Measure the outside diameter of your burette; if it falls within 22 mm, the clamp can grip it, with the rubber-covered ends protecting the glass.

Why are the jaw ends covered with rubber?
The rubber-covered jaw ends on the Clamp Bar Clamps (Counter Clamp) cushion the glass and improve grip, so the burette is held firmly without bare metal pressing on it. This reduces the risk of scratching or cracking during repeated titrations.

Who manufactures this burette clamp?
Jain Scientific Equipments Pvt Ltd (ScienceLab) manufactures the Clamp Bar Clamps (Counter Clamp) as OEM at its own licensed factory in Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers buy it direct from the factory, and quotations are prepared by the manufacturer.

How should it be looked after?
Wipe the Clamp Bar Clamps (Counter Clamp) dry after titrations, especially if acid or alkali drips onto it, because the mild steel body lasts longer when kept free of spills. Check the rubber on the jaw ends from time to time and ask us about replacements if it wears.

Can I order clamps for a whole lab?
Yes. For a quotation on Clamp Bar Clamps (Counter Clamp), tell us how many titration stations you are equipping, your delivery location and whether stands, burettes or flasks should be included. Schools, colleges, dealers and importers can order in bulk from the manufacturer.

Elastic Clamps for Rubber Pipes (Mohr Clamp) (Product Code: SCI-759/033) is a steel spring pinch clamp used to squeeze rubber tubing shut, or release it, to stop and start the flow of liquid or gas in laboratory apparatus. It takes tubing within a maximum space of 16 mm, and its chemical-resistant silver steel suits wet bench work as everyday chemistry lab equipment in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.

Specifications

What Is the Mohr Clamp Used For?

The Mohr clamp is the on-off switch of rubber tubing. It closes the rubber outlet of a burette or dropping set-up that uses a tube instead of a stopcock, shuts a gas delivery line while one full gas jar is exchanged for an empty one, and holds a siphon closed until the receiving vessel is in place. Pressing the clamp opens the jaws and releasing it lets the spring close them again, so a single hand controls the flow.

Fit the clamp on a straight length of tubing, well away from glass joints, so the pinch does not strain the connection. Where a partial, steady flow is needed, pair it with a Hoffman screw clamp, which closes by degrees. Remove the clamp from tubing that is being stored, otherwise the rubber takes a permanent crease, and rinse and dry the steel after it has been splashed with chemicals.

OEM Manufacturer

Jain Scientific Equipments Private Limited, which trades as ScienceLab, is the original equipment manufacturer of these Mohr clamps and makes them at its own licensed factory in Saha, Ambala, Haryana, India. Schools and colleges, as well as dealers and importers, buy them straight from the factory, so extra clamps for new benches or replacements for lost ones are quoted by the maker — just ask us. See the ScienceLab company profile for background.

Related Laboratory Equipment

Flow control with rubber tubing usually involves these items as well:

• Rubber Tube (Laboratory) — the tubing the clamp closes.
• Tightening for Screw Pipes (Hoffman Clamp) — a screw clamp for adjustable flow.
• Screw Pipe Clamp (Hoffman Clamp) — another screw clamp listing for tubing.
• Glass Pipes of Different Diameters — glass connectors joined by rubber tubing.

Find more clamps and fittings in the Laboratory Equipment category.

Frequently Asked Questions

What does the Mohr clamp do?
Elastic Clamps for Rubber Pipes (Mohr Clamp) pinch rubber tubing shut to stop the flow of liquid or gas, and open it again when the clamp is pressed. It is a quick on-off clamp for burette outlets, siphons and gas delivery lines in laboratory set-ups.

What tubing size does it take?
Elastic Clamps for Rubber Pipes (Mohr Clamp) have a maximum space of 16 mm between the jaws, so they suit rubber tubing that fits within that opening. If you are unsure about a particular tube, send us its outer diameter through the contact page.

How is a Mohr clamp different from a Hoffman clamp?
