Burette Racks (Product Code: SLE/CH/23) is a single-burette holder built entirely from seasoned hardwood, with a 200 × 100 mm base, a rod of approximately 460 mm height and 16 mm diameter, and moulded plastic clamping screws that grip the burette without metal touching the glass. It gives each student a self-contained burette stand for titrations at the bench. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a straightforward burette stand for labs in India and international markets that prefer wood over metal hardware.
| Parameter | Detail |
|---|---|
| Type | Burette holder for a single burette |
| Material | Seasoned hardwood throughout, well polished |
| Base size | 200 × 100 mm |
| Rod size | Approx. 460 × 16 mm (height × diameter) |
| Clamping | Moulded plastic clamping screws |
This holder is set up at a student position for acid-base, redox or precipitation titrations. The burette is clamped to the wooden rod with the plastic screws, the conical flask sits on the base beneath the jet (a white tile makes the end-point colour easier to see), and the student operates the stopcock with one hand while swirling the flask with the other. The hardwood base is broad enough to keep the tall rod steady during this routine.
Because it is dedicated to one burette and needs no boss head or separate clamp, it suits titration kit setups for schools where quick assembly matters. Tighten the plastic screws just enough to hold the burette vertical, check the alignment against a vertical edge before reading, and wipe the base if titrant drips onto it.
Made by Jain Scientific Equipments Private Limited, which trades as ScienceLab and is based in Ambala, Haryana. You can read about the company in our company profile.

Balance Double Beam (Product Code: SLE/CH/24) is a single-pan mechanical balance on a wooden base with a capacity of 311 g and a sensitivity of ±2 mg. Captive weights slide along the beam scales and the result is read from an index scale and pointer, so there are no loose weights to lose or mix up. It is intended for speed when weighing routine samples, which makes it a dependable chemical balance for Indian school, college and training labs. The balance is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.
| Parameter | Detail |
|---|---|
| Type | Double beam balance, single pan, captive sliding weights |
| Reading | Index scale and pointer |
| Capacity | 311 g |
| Sensitivity | ±2 mg |
| Scale division – rear scale | 0 to 1 g × 100 mg |
| Scale division – middle scale | 0 to 1 g × 100 mg |
| Scale division – front scale | 0 to 1 g × 100 mg |
| Distance from suspension | 170 mm |
| Hook to pan | 170 mm |
| Pan diameter | 110 mm |
| Mounting | Wooden base |
A beam balance of this kind is used wherever many samples of similar mass have to be weighed one after another: measuring out salts for solution preparation, weighing crucibles before and after heating in water-of-crystallisation experiments, or checking reagent portions in school practicals. Pharmacy and teaching labs that train students in the principle of the double beam balance also value it, because every step of the weighing is visible on the beams rather than hidden inside electronics.
Set the balance on a level, vibration-free bench away from draughts, zero it with the pan empty, and then slide the captive weights until the pointer returns to the index. Never place hot objects or loose chemicals directly on the 110 mm pan; use a watch glass or weighing boat, and clean the pan after each session.
The balance is manufactured by Jain Scientific Equipments Private Limited, operating as ScienceLab from Ambala in Haryana, India. Details of the company are in our company profile.
Other weighing options and alternatives from our range:
More apparatus is available in the Chemistry Lab Equipment category.
What is the maximum load of this balance?
311 g, with a sensitivity of ±2 mg.
Does it need a separate set of weights?
No separate weight box is listed as required — the balance uses captive weights that slide on the beam scales and stay attached to the instrument.
How large is the weighing pan?
The pan is 110 mm in diameter, with 170 mm from hook to pan.
Is a calibration certificate available?
Please discuss calibration documentation with us before ordering through the contact page; we will tell you what can be provided for your order.

Balance Triple Beam (Product Code: SLE/CH/25) is a single-pan mechanical balance with three notched weighing beams and centre-indicating sliding masses, giving a direct capacity of 610 g that can be raised to 2610 g by hanging supplementary masses on the end of the beam. Magnetic damping brings the pointer to rest quickly, and a 150 mm stainless steel pan takes beakers, specimens and bulky samples. Manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, it is a versatile piece of chemistry lab equipment for schools and colleges in India and abroad.
| Parameter | Detail |
|---|---|
| Type | Single-pan triple beam balance with three tiered, notched beams |
| Capacity (beams only) | 610 g |
| Capacity (with supplementary masses) | Up to 2610 g |
| Beam 1 | 0 to 500 g × 100 g |
| Beam 2 | 0 to 100 g × 10 g |
| Beam 3 | 0 to 10 g × 0.1 g |
| Supplementary masses | 2 × 1000 g, hung on the end of the beam; stored in the recessed base when not required |
| Damping | Magnetic |
| Pan | Stainless steel, 150 mm diameter |
The triple beam balance is a workhorse for class practicals that need a wider weighing range than a small beam balance offers. Students use it to find the mass of irregular solids for density determination, to weigh beakers of water in heat and calorimetry experiments, and to measure larger quantities of salts or soil samples. Mass measurement is part of CBSE physics practical work as much as chemistry, so one balance often serves both departments.
Weighing is done beam by beam: move the rider on the 0–500 g beam to the largest notch that keeps the pointer from dropping, then the rider on the 0–100 g beam, and finish with the fine 0–10 g beam read to 0.1 g. For loads over 610 g, hang the 1000 g supplementary masses on the beam end and add their value to the reading. Magnetic damping means the pointer settles in a few seconds, so students spend less time waiting. Store the masses in the base recess so they are not misplaced.
This balance is produced by Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597), which trades as ScienceLab. The company manufactures at its licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana (Factory Licence AMB-ONLINE-CHD-J-414). See our company profile for more.

What is the capacity of the Balance Triple Beam?
610 g using the three beams alone, and up to 2610 g when the two 1000 g supplementary masses are hung on the end of the beam.
What is the finest reading?
The finest beam reads 0 to 10 g in 0.1 g divisions.
Are the supplementary masses included?
Yes, the specification lists 2 × 1000 g supplementary masses, which store in the recessed base when not in use.
What does magnetic damping do?
It slows the beam’s swing so the pointer settles quickly, making readings faster and steadier than on an undamped balance.
Can you provide a calibration certificate?
Calibration paperwork should be discussed with us before ordering — please raise it through the contact page.
How should I care for the balance?
Keep it level and clean, return all riders to zero after use, and never drop objects onto the stainless steel pan.

Burner Bunsen With Stopcock (Product Code: SLE/CH/27) is a Bunsen burner fitted with its own stopcock, so the gas can be shut off completely at the burner rather than only at the bench tap. It also has an air regulator for flame control and comes with one spare gas nipple for use with LPG. That combination of on-burner shut-off and LPG readiness makes it a sensible choice for any school lab setup in India or abroad where many students light burners at once. It is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.
| Parameter | Detail |
|---|---|
| Type | Bunsen burner with stopcock |
| Gas shut-off | Stopcock to completely stop the flow of gas |
| Air control | Air regulator provided |
| Supplied with | One spare gas nipple for use with LPG |
| Suitable for | General heating in school, college and teaching laboratories |
The stopcock is the reason to choose this burner. When a class is heating test tubes, running flame tests or boiling solutions, students can turn the gas off at the burner the moment they finish, without reaching across the bench to the service tap — and a teacher can see at a glance whether each burner is closed. It also lets a burner be left connected to the supply while turned fully off between steps of a practical.
For labs that run on cylinders, the spare nipple provided for LPG means the burner can be set up for that gas. Fit the correct nipple before connecting the tubing, then light the burner with the air regulator nearly closed and open it gradually to obtain the hot blue flame. Always close the stopcock and the bench tap at the end of the session.
This burner comes from Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer that sells its laboratory apparatus under the ScienceLab brand. Our company profile gives more background.
Products that complete a burner station:
Find stands, gauze and glassware in the Chemistry Lab Equipment category.
What is the stopcock for?
It stops the gas flow completely at the burner, giving students a shut-off within easy reach and an extra safety point besides the bench tap.
Can it be used with LPG?
Yes — a spare gas nipple is provided for use with LPG. For other gas supplies, tell us what your lab uses and we will confirm.
Can I control the flame temperature?
Yes, through the air regulator: more air gives a hotter blue flame, less air a cooler yellow flame.
What is the burner tube size and height?
Tube dimensions are not stated in our current listing for this model. Please contact us for the dimensional details.
How do I maintain the stopcock?
Operate it gently, keep it free of dust and spilled material, and check for gas leaks with soapy water if it ever feels loose. Replace tubing that shows cracks.
Is there a warranty?
Warranty terms are confirmed in our quotation for your order.
Can you equip a whole lab or an export order?
Yes. Send the number of burners, the gas type and the destination in India or abroad, and we will quote burners and tubing together.
For prices, contact us or add this burner to your enquiry cart.

Absorption Tower Calcium Chloride (Product Code: SLE/CH/28) is a cylindrical glass drying tower with a tubule at its base, 335 mm tall and 65 mm in diameter, holding 250 ml of drying agent. Filled with anhydrous calcium chloride or a similar desiccant, it removes moisture from a gas stream passing through it, or protects a reaction vessel from damp air. It is used in chemistry teaching labs, college practicals and research setups, and is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, within our chemistry lab glassware range.
| Parameter | Detail |
|---|---|
| Type | Calcium chloride absorption (drying) tower |
| Material | Glass |
| Shape | Cylindrical, with tubule at base |
| Dimensions | 335 mm height × 65 mm diameter |
| Capacity | 250 ml |
A drying tower sits in the gas line between the generator and the point of use. In a school or college gas collection apparatus, gas from a flask or Kipp-type generator enters through the tubule at the base, rises through the packed calcium chloride and leaves dry at the top, ready to be collected or passed into the next stage of the experiment. It can also be fitted to the inlet of an apparatus as a guard, so that air drawn in is dried first.
Place a plug of glass wool or cotton above the tubule so granules do not fall into the inlet, then fill with lumps or granules of drying agent, leaving space for another plug at the top. Clamp the tower upright on a stand, since a 335 mm glass column filled with desiccant is top-heavy. Replace the drying agent once it turns wet or cakes, and remember that calcium chloride is not suitable for drying every gas — check your procedure before use.
The absorption tower is made by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and supplies laboratory glassware and apparatus to educational and research buyers. More information is on our company profile.

Calcium Chloride Tube, Borosilicate Glass (Product Code: SLE/CH/29) is a U-shaped drying tube with a side tube and stopper, used to strip moisture from a gas stream or to keep damp air away from a reaction. Chemistry teachers, college demonstrators and analysts pack it with a granular drying agent and connect it in line with gas generators and reaction flasks. It belongs to the range of borosilicate laboratory glassware in India made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.
| Parameter | Detail |
|---|---|
| Type | Calcium chloride (drying) tube |
| Material | Borosilicate glass |
| Shape | U-shape with side tube |
| Closure | Stopper |
| Sizes available | 100 x 12 mm; 125 x 15 mm; 150 x 18 mm |
| Supplied as | Empty tube; drying agent is a separate item |
In a gas-preparation practical the tube sits between the generating flask and the receiver: gas enters one limb, passes through the packed drying agent and leaves through the side tube before it is collected. It is a routine addition to school gas collection apparatus in India whenever students need a dry sample of a gas such as hydrogen, oxygen or carbon dioxide. Fitted to the top of a reflux condenser, the same tube works as a guard tube that stops atmospheric moisture from entering a water-sensitive reaction.
Fill it with small lumps or granules rather than fine powder, which packs tightly and chokes the gas flow, and hold the charge in place with a loose plug of glass wool or cotton at each end. Replace the drying agent as soon as it turns wet or caked, and remember that calcium chloride is not suitable for drying ammonia.
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana, which makes laboratory glassware, apparatus and teaching equipment for schools, colleges and research labs. The company is a registered MSME (Udyam UDYAM-HR-01-0003714) and ships overseas under Importer-Exporter Code AAECJ8618A issued by the DGFT. Read more on our company profile.

Browse the full Chemistry Lab Equipment range for stands, clamps and other glassware.
What is supplied with the calcium chloride tube?
The U-shaped borosilicate glass tube with its side tube and stopper. The drying agent is ordered separately, so you can choose calcium chloride or another desiccant to suit the gas you are drying.
Which of the three sizes should I order?
Pick by how much drying agent and gas flow you need: 100 x 12 mm suits small student set-ups, while 125 x 15 mm and 150 x 18 mm hold a larger charge for longer runs. If you need to confirm how a size will fit an existing apparatus, ask us through the contact page.
Can calcium chloride dry any gas?
No. It works for many common laboratory gases, but it reacts with ammonia, so a different drying agent is needed for that gas.
How should the tube be cleaned between uses?
Tip out the spent drying agent, rinse with tap water to dissolve the residue, finish with distilled water and let the tube dry completely before refilling it.

Carboy With Stop Cock (Product Code: SLE/CH/30) is a polypropylene storage container with a leak-proof spigot, used to hold and dispense distilled water and other laboratory solutions at the bench. Labs that want an alternative to heavy glass carboys choose it for daily water supply, rinsing stations and stock solutions. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, as part of its lab plastic ware range for schools, colleges and testing laboratories in India.
| Parameter | Detail |
|---|---|
| Material | Polypropylene |
| Capacity | 10 litres; 20 litres |
| Outlet | Leak-proof spigot (stop cock) screwed to the body |
| Sterilisation | Autoclavable |
| Intended contents | Distilled water and other laboratory solutions |
Most labs place the carboy on a shelf or bench edge next to the water still so that students and technicians can draw distilled water from the spigot without lifting or tipping a heavy container. It is equally useful for bulk buffer, dilute acid or salt solutions that are drawn off in small portions through the day, which keeps the stock sealed and reduces contamination compared with repeated pouring.
Stand the carboy slightly above the receiving vessel so the tap drains freely, and keep the spigot closed when refilling. Label each carboy with its contents and filling date, rinse it with a little of the new solution before topping up, and use the autoclavable body to sterilise it when it is needed for microbiology or media work. This makes it a practical, durable piece of chemistry lab equipment in India for both teaching and routine testing.
Jain Scientific Equipments Private Limited trades as ScienceLab from Ambala, Haryana, producing plasticware, glassware and apparatus for teaching and testing laboratories. Company background and facilities are described on our company profile.
Items that complete a distilled-water or solution-dispensing station:
More storage and handling items are listed in Chemistry Lab Equipment.
Which capacities are available?
Two: 10 litres and 20 litres. The smaller size is easier to lift for refilling; the larger one suits busy labs that use a lot of distilled water.
Can the carboy be autoclaved?
Yes, the polypropylene carboy is autoclavable. Loosen the closure before the cycle so pressure can equalise, and let it cool before handling.
Is the stop cock fixed or replaceable?
The leak-proof spigot is screwed to the body. For a spare spigot, please ask through our contact page with the capacity of your carboy.
Can I store organic solvents in it?
It is intended for distilled water and laboratory solutions. For organic solvents, strong oxidisers or other aggressive chemicals, confirm compatibility with us before use.
Why choose polypropylene instead of a glass carboy?
It is lighter to move and much less likely to break if knocked, which matters in student labs, and it can still be sterilised in an autoclave.
What should an institutional enquiry include?
The capacity, quantity, delivery address and any tender or purchase-order format you use. We supply buyers across India and international markets.
Tell us the capacity and number of carboys through the contact form, or place them in the enquiry cart and we will reply with a quotation.
