What Is Laboratory Rubber Tubing Used For?
Rubber tubing is the flexible link in many set-ups: it joins a glass delivery tube to a second piece of glassware, carries cooling water to and from a condenser, connects a burner to the gas tap, and lets a gas generator feed a trough or gas jar without rigid glass bends. With a pinch or screw clamp fitted, it also works as a simple valve to stop or regulate flow.
To fit it, moisten the end of the glass tube with water or a little glycerol and ease the rubber on with a twisting motion, protecting your hand with a cloth; never force it. Keep the tube within its −25 °C to +70 °C rating, away from flames and hot plates, and check the suitability of natural rubber before using it with oils or organic solvents. Replace any length that has become hard, sticky or cracked, particularly on gas lines.
What to Specify When Ordering
- The total length or number of pieces needed; ask us how the tubing is supplied.
- The outer diameter of the glass tubes or nozzles it must fit, to check against the 6 mm bore.
- Any use outside −25 °C to +70 °C, or with vacuum or solvents, so that a different tubing can be considered.
- Clamps for closing or regulating the tube.

Test Tube Clips
Test Tube Clips (Product Code: SCI-524/017) is a wooden test tube holder used to grip a single test tube while it is heated, shaken or poured in school and college laboratories. Because wood is a poor conductor of heat, students can hold a hot tube over a flame at a safe distance instead of touching the glass, which makes the clip basic school chemistry lab equipment. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
Key Details

| Product code | SCI-524/017 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is a Test Tube Clip Used For?
The clip is used whenever a test tube should not be held by hand: heating a liquid or solid over a spirit lamp or burner, carrying a tube that holds a corrosive reagent, or shaking a warm mixture. Grip the tube near its mouth, about a third of the way down, so that the clip stays well above the flame and the lower part of the tube can be heated evenly.
When heating a liquid, tilt the tube, point the mouth away from yourself and others, and move it gently in the flame so that the contents do not bump out. Keep the wooden clip itself out of the flame, as it can scorch, and let it cool before storing it. A set of clips alongside test tubes and a rack forms a basic chemistry experiment kit for each bench.
What to Specify When Ordering
- The number of clips, for example one per student or pair.
- The diameters of the test tubes the clip must hold, since the grip size is not listed.
- Matching test tubes and racks, if they should be quoted together.
OEM Manufacturer
Test Tube Clips are made by ScienceLab, the trading name of Jain Scientific Equipments Private Limited, which is the OEM (original equipment manufacturer) and produces them at its own licensed factory at Saha, Ambala, Haryana, India. Schools, colleges, dealers and importers order them factory-direct, and bulk or repeat quantities are quoted by the manufacturer itself rather than through a middleman.

| Base | Stable, for single-handed operation |
| Product code | SCI-159/018 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is a Pipette Holder Used For?
Micropipettes are best stored upright: lying on the bench, a pipette with liquid left in its tip can let that liquid run back towards the piston, and the pipette can roll, fall or be knocked. A carousel holder parks each pipette vertically after use, keeps a set of different volumes together at one workstation, and frees bench space in busy practical classes.
Remove the used tip before placing a pipette in the stand, then turn the carousel to bring the required volume within reach and lift it out with one hand while the stable base stays put. Wipe the stand with a damp cloth and mild detergent when it gets dusty or splashed. It is a small but useful part of the microbiology lab equipment in India's colleges and research laboratories.
What to Specify When Ordering
- The number of stands, for example one per workstation.
- The pipette types to be held, single-channel or multichannel, so the fit can be confirmed.
- How many pipettes each bench uses, as each stand holds 15.
OEM Manufacturer
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM (original equipment manufacturer) of the Pipette Holders and makes them at its own licensed factory at Saha, Ambala, Haryana, India.

| Purpose | Holds test tubes upright |
| Product code | SCI-293/019 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the 12-Hole Test Tube Holder Used For?
A rack keeps every tube in a known order, which matters when students compare results: a row of tubes testing different foods for starch, an indicator in solutions of different pH, or a dilution series of a coloured solution can stand side by side and be read at once. It also gives a safe place to set down a warm tube taken from a clip, so that tubes are never laid flat on the bench.
Label the tubes or the rack positions before starting so that samples cannot be mixed up. Wipe the wooden rack dry after spills rather than soaking it, and clean chemical splashes off promptly so the wood does not stain or swell. When drawing up school chemistry lab equipment lists, plan one rack per practical group.
What to Specify When Ordering
- The number of racks, for example one per practical group.
- The outer diameter of the test tubes you use, since the hole size is not listed.
- Any test tubes, clips or stoppers to be quoted with the racks.
OEM Manufacturer
Jain Scientific Equipments Private Limited, trading as ScienceLab, is the original equipment manufacturer (OEM) of these wooden Test Tube Holders, which are made at its own licensed factory at Saha, Ambala, Haryana, India.

Atom Models
Atom Models (Product Code: SCI-995/020) is a set of coloured spheres used to build models of atoms, showing protons and neutrons in the nucleus and electrons around it, in school chemistry and physics lessons. It contains 48 yellow electron spheres, 57 red or green proton spheres and 57 black neutron spheres, so learners can assemble and compare different atoms as a hands-on atom model kit. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
Specifications
| Parameter | Detail |
|---|---|
| Electrons | 48 spheres, yellow |
| Protons | 57 spheres, red or green |
| Neutrons | 57 spheres, black |
| Product code | SCI-995/020 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Are Atom Models Used For?
Building an atom from separate spheres turns the numbers on the periodic table into something pupils can count. The number of red or green protons fixes the element, black neutrons are added to reach the mass number, and yellow electrons equal in number to the protons make the atom neutral; arranging those electrons in shells of 2, 8 and 8 then shows why elements in the same group behave alike.
The same pieces show isotopes, by changing only the neutron count, and ions, by adding or removing electrons. The set also works as a science model kit for school projects on atomic structure. Sort the spheres back by colour after each lesson so that the counts stay complete for the next class.
What to Specify When Ordering
- The number of sets, for example one per group.
- Your preferred proton colour, red or green, as the listing allows either.
- Whether a base, shell rings or connecting parts are needed, as they are not listed with the spheres.
OEM Manufacturer
ScienceLab is the OEM (original equipment manufacturer) of the Atom Models, which are produced at the company's own licensed factory at Saha, Ambala, Haryana, India, and supplied factory-direct to schools, colleges, dealers and importers. The brand belongs to Jain Scientific Equipments Private Limited, so quotations, requests for extra spheres and repeat orders all go to the maker itself.

| Application | Modelling organic and inorganic compounds |
| Product code | SCI-655/021 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Are Molecular Micro-Models Used For?
Formulae on a page hide the shapes of molecules; a model makes them visible. Students can build methane to see its tetrahedral shape, water to see why it is bent and carbon dioxide to see why it is straight, then move on to chains and rings in organic chemistry. Building two molecules with the same formula but different arrangements, such as butane and its branched isomer, shows clearly why isomers have different properties.
Because the balls come in different sizes as well as colours, a class can agree a colour and size code for each element before building, which keeps models consistent between groups. Count the pieces into a tray at the start and end of each lesson, as small lugs are easily lost. The set suits molecular model work in organic chemistry at senior school and college level, as well as introductory inorganic topics.
What to Specify When Ordering
- The number of sets, for example one per student pair or group.
- Whether your focus is organic compounds, inorganic compounds or both, so the set can be matched to your syllabus.
- The number of pieces and the colours you need, as these are not listed; ask us to confirm them.
OEM Manufacturer
ScienceLab, the trading name of Jain Scientific Equipments Private Limited, is the OEM (original equipment manufacturer) of the Molecular Micro-Models and makes them at its own licensed factory at Saha, Ambala, Haryana, India.

| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the 500 ml Washing Bottle Used For?
A wash bottle delivers liquid exactly where it is needed. Typical jobs include giving beakers and flasks a final rinse with distilled water after washing, rinsing the last traces of a precipitate from a beaker onto filter paper, bringing a volumetric flask up to the mark drop by drop, and rinsing a pH electrode between readings.
The 90° nozzle lets the jet reach the inside walls of a flask or the edge of a filter funnel without tipping the bottle, and a gentle squeeze gives a thin stream while a firmer one gives a stronger jet. Keep one labelled bottle for each liquid, such as distilled water or ethanol, so that rinses are never contaminated, and screw the cap tight when a volatile solvent is stored in it. Check chemical compatibility with us before filling it with strong solvents.
What to Specify When Ordering
- The number of bottles, for example one per bench for each rinse liquid.
- The liquids to be dispensed, so that chemical compatibility can be confirmed.
- Whether you need the bottle alone or a tray or set, since the name mentions trays but the listing describes the bottle only.

A single bore turns a simple closure into a connection point. In gas preparation, the stopper closes a boiling tube or flask while a delivery tube carries the gas to a gas jar or into lime water. In heating and cooling experiments, it holds a thermometer at a fixed depth in a test tube, and in simple wash bottles it anchors a bent glass tube — everyday tasks on school chemistry lab equipment lists in India.
Choose the size so that the stopper enters the neck partway and sits firmly without being pushed fully inside. Remove glass tubes after the practical so the rubber does not grip them permanently, and keep stoppers away from direct flame. Storing them in a closed box, out of sunlight, helps the rubber stay flexible.
What to Specify When Ordering
- The bottom diameter(s) needed: 11 mm, 13 mm, 14 mm or 15 mm.
- The quantity of each size, per bench or per laboratory.
- The glassware the stoppers will close, so each size can be checked against its neck.
- Whether solid stoppers without holes should be quoted on the same enquiry.
