The Electric Bulb (Product Code: SCL-647/072) is a 60 watt incandescent lamp of the traditional filament type, giving white light and suitable for indoor and outdoor use. In the laboratory it is the indicator lamp of the conductivity test — its brightness shows at a glance how well a solution conducts — and its glowing filament is a clear example of the heating effect of electric current. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, together with the holders, switches and wire needed to use it.

Specifications

Typical Use

Fitted in a holder in series with two electrodes, the bulb lets a class compare solutions: full brightness with salt solution or a dilute mineral acid, a faint glow with a weak acid, and no light at all with distilled water or sugar solution. Because a filament lamp brightens gradually as current increases, differences between strong and weak electrolytes are easy to see. Physics teachers also use it to show that a current-carrying filament becomes hot enough to emit light, and as a radiant heat source in the experiments that go with a heat energy science kit.

An incandescent bulb runs hot. Switch off and allow it to cool before removing it from the holder, handle it with dry hands, and position it so that liquids cannot splash onto the hot glass, which can crack on sudden cooling. Mains-powered demonstrations should always be operated by the teacher.

Supplier

This bulb is supplied by Jain Scientific Equipments Private Limited, an Ambala, Haryana company that trades as ScienceLab and equips educational laboratories in India. The company profile explains more about us.

Frequently Asked Questions

What wattage is the bulb?
It is a 60 W incandescent filament bulb giving white light.

Why use a filament bulb rather than an LED for conductivity tests?
A filament lamp glows progressively brighter as current rises, so weak and strong electrolytes produce visibly different brightness. That graded response is what makes the comparison work in class.

Which cap or base does it have?
The cap type is not stated in our current listing. Contact us with your holder type and we will confirm a matching bulb.

Can it be used outdoors?
The listing describes it as suitable for both indoor and outdoor use.

Is there a warranty on bulbs?
Bulbs are treated as consumables; any warranty terms are confirmed at quotation stage, so please check with us before ordering.

Can bulbs be included in a larger lab supply order?
Yes. We supply schools, colleges and distributors in India and international markets, and bulbs can be quoted along with holders, switches and wire.

Rubber Bands (Good Quality) (Product Code: SCL-649/073) are general-purpose elastic bands made of rubber, kept on the chemistry bench for the many small fastening jobs of a practical session: holding a paper or cloth cover over a beaker, keeping a balloon seated on the neck of a flask, or bundling glass rods and tubes for storage. The bands have good elasticity and a durable build, so they stretch over vessel rims and spring back instead of snapping after a few uses. Lab assistants and teachers usually add them to a chemistry consumables order alongside labels and filter paper. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

Typical Use

A rubber band is the quickest way to keep a loose cover firmly on a vessel. Stretch one around a square of filter paper or muslin laid over a beaker to keep dust out of a solution left to crystallise overnight, or loop it round the neck of a flask so that a balloon stays in place while a gas-producing reaction inflates it. Bands also group glass rods, droppers or test tubes into ready sets for each student bench, and keep instruction cards or label strips attached to trays and bottles during a busy practical.

Keep rubber away from open flames, hot plates and freshly heated glassware, because heat softens it and makes it snap. Strong oxidising acids and many organic solvents also attack rubber, so a band should hold a cover in place but never be relied on to seal such liquids. Store spare bands in a closed box out of direct sunlight to preserve their stretch, and throw away any that turn sticky or brittle. As a lab consumables supplier in India, ScienceLab can pack them together with the other small items a practical room reorders each term.

Supplier

Jain Scientific Equipments Private Limited trades as ScienceLab and is based in Ambala, Haryana. The company supplies everyday consumables such as these rubber bands, so institutions can source a complete practical set-up from one vendor. Learn more on the ScienceLab company profile.

Frequently Asked Questions

What are these rubber bands made of?
They are made of rubber with good elasticity and a durable build, intended for repeated stretching during routine lab work.

What band sizes and pack quantities can I order?
Band dimensions and pack counts are not fixed in this listing. Tell us the quantity and the job you need them for through the contact page and we will confirm what can be supplied.

Can a rubber band make an airtight seal?
No. It holds a cover, balloon or label in place, but it does not create a gas-tight or leak-proof closure. Use a proper cork or stopper where a seal matters.

Are they safe to use near a burner or with solvents?
Keep them away from flames, hot surfaces, strong oxidising acids and organic solvents, all of which soften or degrade rubber.

How should spare bands be stored?
In a closed container in a cool place away from direct sunlight. Discard bands that have become sticky, cracked or brittle.

Do you supply larger quantities for several labs or for export?
Yes. ScienceLab supplies schools, colleges and dealers in India and international markets; share the quantity and delivery location when you enquire.

Reagent Racks (Product Code: SCL-653/075) is a wooden bench rack that keeps a working set of reagent bottles upright and in a fixed order at a chemistry practical table. It offers 12 places in a three-tier arrangement, with chemicals stored on two sides, so students working on either side of a shared bench can reach the same reagents without passing bottles across. The brown wood is laminated with sunmica, giving a smooth outer surface that is easier to wipe down than bare timber. It is a standard piece of school chemistry lab equipment for salt analysis and titration benches, made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

Place one rack at the centre of each chemistry bench and fill it with the reagents a practical calls for: dilute acids, ammonia solution and the common group reagents for qualitative salt analysis, or indicators and standard solutions for a titration class. Keeping every bench in the same order helps students learn where each bottle belongs, reach for the right reagent quickly and return it to its own place, which cuts down on mix-ups and cross-contamination of stoppers. Bulk stock stays in the chemistry reagent cabinet, while the rack holds only the day's working bottles.

Label each bottle clearly and keep the larger or heavier ones on the lowest tier for stability. Wipe any drips from the sunmica surface straight away with a damp cloth, since acids and alkalis left standing can mark wood at the edges and joints. Keep the rack away from burners and hot plates, and check it each term for loose joints before the bottles go back in.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), a company based in Ambala, Haryana. It manufactures laboratory apparatus at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala (Factory Licence AMB-ONLINE-CHD-J-414) and supplies schools, colleges and dealers in India and international markets.

LPG Gas Connection with 2 Refills (Product Code: SCL-658/077) is a commercial LPG (liquefied petroleum gas) connection supplied together with two refills, giving a chemistry laboratory its own fuel source for gas burners. It suits schools and colleges that do not have piped natural gas but need a steady flame for heating, boiling, evaporation and flame tests during practicals. Institutions setting up a new chemistry room often order it at the same time as their burners and tubing so the benches are ready to use from the first class. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

Typical Use

Once installed, the connection feeds the gas line that serves the Bunsen burner on each bench, so students can heat test tubes, bring solutions to the boil, evaporate filtrates in a china dish, carry out flame tests and bend glass tubing. Having two refills with the connection means a lab can keep one in use and one in reserve, so a practical is not interrupted when the gas runs out mid-term. Burners and tubing should be ones intended for LPG, and the teacher should show every class how to open the bench tap only after the lighter is ready.

Keep the cylinder upright in a well-ventilated place away from burners, hot plates and direct sunlight, and never inside a closed cupboard. Close the cylinder valve at the end of each session, check hose joints with soap solution rather than a flame, and replace worn tubing promptly. If gas can be smelled, shut the valve, avoid any flame or electrical switch, open doors and windows and call the gas distributor. Following these routines is as much a part of setting up chemistry lab equipment in India as choosing the burners themselves.

Supplier

Jain Scientific Equipments Private Limited operates under the ScienceLab name from Ambala, Haryana. The company supplies items such as this LPG connection so that institutions can complete a working lab set-up through one vendor. More about the company is on the ScienceLab profile page.

Bell Jar, Knobbed (Product Code: SCL-665/080) is a bell-shaped glass cover used to contain a vacuum, made from neutral glass with a ground flange at the rim and a knob at the top for lifting. At 100 mm in diameter and 200 mm high it is sized for compact bench demonstrations, and the thin glass is made with extra care for optical clarity, so students can see clearly what happens inside as the air is removed. Teachers of chemistry and physics use it to show the effects of reduced pressure, and it sits comfortably within a school's chemistry lab glassware. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

Stand the jar on a flat, smooth plate connected to a vacuum pump and draw the air out to show classic reduced-pressure effects: a partly inflated balloon swelling as the pressure around it falls, warm water beginning to boil without further heating, or a small battery buzzer growing faint as there is less air to carry its sound. Because the glass is clear, a whole class can watch from the bench. Outside vacuum work, the same jar can serve as a clear dust cover over small apparatus or as an enclosure for a potted seedling in a simple transpiration set-up.

For a good seal, spread a thin, even film of petroleum jelly or vacuum grease on the ground flange before placing the jar. Inspect the glass for chips and scratches before every evacuation, work behind a safety screen and let air back in slowly before lifting the jar by its knob. Clean it with mild detergent and a soft cloth to protect the clarity of the glass. It is a practical addition for any school buying from a lab glassware manufacturer in India that wants demonstration pieces as well as everyday vessels.

Manufacturer

ScienceLab is the brand of Jain Scientific Equipments Private Limited, a company based in Ambala, Haryana, that manufactures laboratory apparatus and glassware for teaching and research institutions in India and international markets. See the ScienceLab company profile for more about the business.

Frequently Asked Questions

What size is the bell jar?
It is 100 mm in diameter and 200 mm high, with a ground flange at the base and a knob at the top.

Does it come with a vacuum plate or pump?
This listing is for the knobbed bell jar. Pumps are listed separately; if you need a plate or a complete set, ask through the contact page and we will advise.

How do I get an airtight seal?
Place the ground flange on a flat, clean plate and apply a thin layer of petroleum jelly or vacuum grease to the flange before evacuating.

Can the jar be heated?
The glass is heat resistant, but a bell jar is a cover for vacuum and enclosure work, not a heating vessel. Keep it away from direct flame and sudden temperature changes.

What safety steps apply under vacuum?
Check for chips or cracks first, use a safety screen during evacuation and release the vacuum slowly before lifting the jar.

Is a calibration or test certificate supplied?
A bell jar is not a measuring instrument. If your purchase process needs any documentation, please discuss it with us before ordering.

Can you supply several jars or ship overseas?
Yes. We supply schools, colleges and dealers in India and international markets; share quantity and destination for a quotation.

Boiling Tubes (Product Code: SCL-667/081) are wide, round-bottomed tubes of clear borosilicate glass, 150 x 25 mm with a rim, used when a reaction or a solution needs more room than an ordinary test tube provides. Their wider bore lets liquids boil more steadily with less risk of spurting, which is why chemistry teachers choose them for dissolving salts, preparing extracts and heating mixtures with reagents. The glass is heat resistant and chemical resistant, fitting the standard expected of borosilicate glassware in India's school and college labs. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

In salt analysis practicals a boiling tube is the natural vessel for making the original solution of a salt, boiling a mixture with sodium carbonate to prepare an extract, or warming a sample with dilute acid while watching for gas. Biology and chemistry teachers also use them to heat liquids in a water bath, to carry out tests that need a larger sample, and as the reaction vessel in simple gas-collection set-ups closed with a bored cork and a delivery tube. The round bottom spreads heat evenly, and the rim gives the holder a secure grip and helps when pouring the contents out.

Fill a tube only to about a third of its height before heating over a flame, hold it at a slant with a test tube holder and point the mouth away from everyone nearby. Warm the tube gently near the surface of the liquid while shaking slightly to prevent bumping, and never heat an empty tube. Between steps the tubes can rest upright in a test tube rack or stand; once cool, clean them with a brush and detergent and rinse with distilled water.

Boiling tubes are handled, held and cleaned with a few everyday accessories:

• Test Tube Holder — holds the tube at a safe angle over the flame.
• Test Tube Stand Poly Lab — keeps tubes upright between steps; check that the holes suit wider tubes.
• Test Tube Brush Nylon — reaches the round bottom when cleaning.
• Corks — close the tube or hold a delivery tube in gas experiments.
• Ignition Tubes — smaller tubes for strongly heating solid samples.

For more tubes and glassware, see the Chemistry Lab category.

Frequently Asked Questions

What are the dimensions of these boiling tubes?
Each tube is 150 x 25 mm, with a rim at the mouth and a round bottom.

How is a boiling tube different from a test tube?
It is wider, so it holds a larger sample and lets liquids boil more steadily. Use it when a test tube would be too narrow or too full.

Can they be heated directly over a burner?
Yes. They are made of heat-resistant borosilicate glass. Heat gradually, keep the tube moving and never heat it dry.

How many tubes come in a pack?
Pack quantity is not specified in this listing. Tell us how many tubes you need through the contact page and we will quote accordingly.

How should they be cleaned?
Let them cool, scrub with a tube brush and detergent, rinse with tap water and then distilled water, and dry upside down.

Droppers with Rubber Bulb (Product Code: SCL-677/085) are glass dropper assemblies that draw up and release liquid a drop at a time when the rubber bulb is squeezed and released. The dropper is made of borosilicate glass, and the assembly is fine ribbed, child-resistant and fitted with a tamper-evident seal, which helps keep stored reagents secure and shows whether a container has been opened. Chemistry and biology teachers rely on them for dispensing small amounts of indicators, stains and test reagents where pouring would be too coarse. They are made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

A dropper is the simplest way to add an exact number of drops: two or three drops of phenolphthalein or methyl orange into a titration flask, a drop of universal indicator solution on a glazed tile for a quick pH check, or a single drop of stain onto a slide in a biology practical. In qualitative analysis, students add a test reagent drop by drop and watch for the first sign of a precipitate or colour change, which a pouring bottle cannot control as finely.

Squeeze the bulb before dipping the tip into the liquid, then release slowly to fill. Keep the dropper pointing downwards once it holds liquid, because liquid that runs back into the bulb shortens the life of the rubber and can contaminate the next reagent. Use a separate dropper for each solution, rinse by drawing up and expelling distilled water a few times after use, and keep the rubber away from organic solvents and heat.

Manufacturer

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana. The company manufactures laboratory glassware and teaching apparatus and supplies it to institutions and dealers across India and international markets. Visit the ScienceLab profile to learn more.

• Bottle Dropping — bottles for keeping reagents that are dispensed by the drop.
• Reagent Bottles For Liquids — stock bottles for the solutions you draw from.
• Glazed Tiles — a white surface for spot tests and colour checks.
• Methyl Orange — an indicator usually added a few drops at a time.
• Pipette, Pasteur — an alternative for transferring small liquid volumes.

Explore the Chemistry Lab category for related glassware and reagents.

Frequently Asked Questions

What are the droppers made of?
The dropper is borosilicate glass and the bulb is rubber.

What does the 110 ml capacity refer to?
110 ml is the capacity listed for this item. If you need the dropper to match particular bottles, send their details through the contact page and we will confirm suitability before you order.

What do child-resistant and tamper-evident mean here?
The fine-ribbed assembly is designed to be child-resistant, and the tamper-evident seal shows whether it has been opened, which is useful for stored reagents.

Can one dropper be shared between reagents?
It is better not to. Use one dropper per solution to avoid cross-contamination, and rinse it thoroughly if it must be reused.

How do I look after the rubber bulb?
Keep liquid out of the bulb, avoid organic solvents and heat, and store the droppers in a cool, dry place.

Can you supply droppers in bulk for several labs or for export?
Yes. ScienceLab supplies institutions and dealers in India and international markets; tell us the quantity and destination.

Gas Jar (Product Code: SCL-686/089) is a tall, open-mouthed cylinder of clear soda glass, 200 x 50 mm, used to collect and hold a gas so that its properties can be tested in front of a class. Students fill it with oxygen, hydrogen or carbon dioxide prepared at the bench, then cover it and carry out tests such as a glowing splint or lime water. The glass is chemical resistant and heat resistant, and its clarity lets everyone watch a colour change or a flame inside. It is a core part of any gas collection apparatus in a school laboratory and is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

Typical Use

For gases that do not dissolve readily in water, fill the jar with water, invert it over a beehive shelf in a pneumatic trough and let the gas from the delivery tube push the water out. Gases that are heavier or lighter than air can instead be collected by upward or downward displacement of air, with the jar standing upright or mouth down. Once full, slide a greased cover over the mouth, lift the jar out and keep it covered until the test.

Typical tests include relighting a glowing splint in oxygen, burning sulphur or magnesium ribbon held in a deflagrating spoon, or shaking carbon dioxide with lime water. When burning anything inside the jar, pour a little sand or water into the bottom first so hot residues cannot crack the base. Although the glass is heat resistant, a gas jar is a collection vessel rather than a heating vessel, so keep it off the burner. These simple habits make it one of the most reliable pieces of chemistry lab equipment in India's school practical rooms.

Manufacturer

Jain Scientific Equipments Private Limited operates as ScienceLab from Ambala, Haryana, manufacturing laboratory glassware and apparatus for schools, colleges and dealers in India and international markets. The company profile gives more background.

Collecting a gas in the jar calls for a few more pieces of apparatus:

• Gas Jar Cover — closes the mouth once the jar is full.
• Pneumatic Trough — the water bath for collecting gas over water.
• Beehive Shelf, Porcelain — supports the inverted jar over the gas outlet.
• Delivery Tube — carries gas from the generating flask to the jar.
• Deflagrating Spoon — lowers burning samples into the collected gas.

Frequently Asked Questions

What size is the gas jar?
It measures 200 x 50 mm and is made of clear soda glass.

Is a cover included?
This listing is for the gas jar. A gas jar cover is available as a separate item and can be quoted with it; ask through the contact page if you want them paired.

Can the jar be heated?
The glass is heat resistant and copes with combustion tests inside it, but it should not be placed over a burner. Protect the base with sand or water when burning samples.

Why soda glass rather than borosilicate?
Gas jars are used for collecting and holding gases rather than direct heating, so soda glass suits the job. Choose borosilicate vessels for anything that goes over a flame.

Which gases can it be used for?
Any gas prepared in school practicals, such as oxygen, hydrogen or carbon dioxide. The collection method depends on how soluble and how dense the gas is.

Do you supply class sets or export orders?
Yes. ScienceLab supplies institutions and dealers in India and international markets; quantities and delivery are confirmed on enquiry.
