Glass Combustion Tube (Product Code: SLE/CH/142) is a small, clear glass tube for heating very small quantities of material in a flame, measuring 4 mm in outer diameter, 2.5 mm in inner diameter and 53 mm in length. The glass is heat resistant and chemical resistant, so the tube copes with direct heating and with contact with the reagents used in routine small-scale tests. Chemistry students, teachers and laboratory technicians use it where only a trace of sample is needed, and it is a handy item of chemistry lab glassware for India’s school and college practical rooms. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

Combustion tubes are used when a sample has to be heated strongly and watched closely: a few crystals are placed inside, the tube is held in the flame, and students record what happens — a change of colour, melting, gas given off, droplets condensing on the cooler part of the glass, or a residue left behind. With a bore of only 2.5 mm, the tube holds a tiny amount of material, which keeps reactions contained and reduces the quantity of chemical each student uses. That makes it a good fit for small-scale qualitative tests and for microscale teaching where many students work at once.

Warm the tube gently at first and then increase the heat, holding it with suitable tongs or a holder and pointing the open end away from everyone nearby. Heat-resistant glass still dislikes sudden temperature changes, so let the tube cool on a heat-resistant mat rather than dropping it into water. Eye protection is essential whenever glass is heated in a flame. For schools buying school chemistry lab equipment in India for a full class, it is worth ordering spare tubes, since a tube that has been strongly heated with a sample is often easier to replace than to clean.

Green Chemistry: Production Of Biodiesel (Product Code: SLE/CH/143) is a classroom kit in which students carry out a two-phase process to produce small batches of crude biodiesel. The fuel they make is of sufficient quality to demonstrate the burning qualities of both biodiesel and vegetable oil, and an optional small-scale washing exercise lets classes go through the full process needed to reach the quality levels required for use in vehicles. Sufficient materials are included for 15 groups, together with a teacher’s manual and student copy masters. It suits teachers looking for a chemistry experiment kit in India that connects reaction chemistry with renewable energy, and it is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

The activity gives a concrete example of green chemistry: turning a renewable raw material, vegetable oil, into a usable fuel. In general terms, biodiesel is made by chemically converting the fats in the oil into a thinner, more easily burned liquid, leaving a glycerol by-product behind. Students work through the two phases of the process in their groups, then compare how the crude biodiesel and the original vegetable oil burn, which makes the difference between the two liquids easy to see rather than just read about.

Classes with extra time can add the optional washing exercise, which shows why fuel sold for vehicles needs further purification than the crude product. The kit also works as an environmental science kit for school energy topics, prompting discussion of renewable feedstocks, emissions and the trade-offs of biofuels. Run the practical in a well-ventilated room, have students wear eye protection, and keep the burning comparison under close teacher supervision on a heat-resistant surface.

Greener Synthesis Of Acetylsalicylic Acid (Product Code: SLE/CH/144) is a multi-step organic chemistry kit that shows how to produce sodium salicylate from a naturally occurring, renewable resource and carry it through to acetylsalicylic acid, the active compound in aspirin. Students convert the sodium salicylate to salicylic acid, check for salicylic acid with a quick confirmatory test, and then use their own prepared salicylic acid for the final synthesis. There are enough materials for 15 groups, plus a teacher’s manual and student copy masters. With its step-by-step structure it works well as a chemistry teaching kit for organic chemistry classes in India and overseas, supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

Because each step produces the starting material for the next, the practical is usually spread over more than one lesson and teaches students something single-step experiments cannot: losses and impurities carry forward, so careful technique early on decides the result at the end. The route also illustrates a core green chemistry idea, using a renewable feedstock, and invites comparison with the way salicylic acid is commonly manufactured from petrochemical sources.

The quick confirmatory test gives groups a checkpoint before they commit their salicylic acid to the final synthesis, which keeps weaker groups from carrying a failed intermediate into the last step. Teachers who want to push further can have students collect the final crystals by suction filtration and compare melting points as a simple purity check. Schools in India looking for a science kit with manual and copy masters ready to photocopy will find the student sheets make marking consistent across groups. Eye protection and supervised handling of reagents are essential throughout, and the product is for laboratory study only.

Gunshot Residue Presumptive Test Kit (Product Code: SLE/CH/145) is a two-part chemical test kit used to check whether a surface may have been exposed to a discharged firearm, in forensic science and chemistry teaching labs. A rapid colour change indicates nitrates and lead, and each kit contains instructions and enough materials for 30 tests. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside other forensic teaching materials for institutions in India and international markets.

Specifications

What Is the Gunshot Residue Presumptive Test Kit Used For?

In a teaching lab, it shows how a presumptive test works in practice. Students follow the instructions, run both parts of the test on surfaces the teacher provides, and record whether the colour change appears for nitrates, for lead, or for both. The two-part design is a useful talking point: a single positive could come from an everyday source, since nitrates are also found in fertilisers, so finding both substances gives a stronger indication than either result alone.

With 30 tests per kit, plan the lesson so each group runs a known negative, such as a clean surface, next to its test sample; this teaches students to trust a result only when the control behaves as expected. Gloves stop hands contaminating the test area, and eye protection should be worn while reagents are in use. Colleges that rely on a chemistry consumables supplier in India often order this kit with blood and drug screening activities to build a complete presumptive-testing module.

Supplier

Jain Scientific Equipments Private Limited, trading as ScienceLab from Ambala, Haryana, India, supplies this test kit as part of its forensic and chemistry teaching range. Schools, colleges and training institutes can combine it with other forensic activity kits, gloves and goggles in a single enquiry. Company background is available on our company profile.

Related Laboratory Equipment

These products sit in the same forensic screening workflow, either as further presumptive tests or as protection while testing:

• Presumptive Blood Test Kit — the same screening idea applied to blood stains
• Forensic Chemistry of Drug Detection — chemical screening for a different type of evidence
• Forensic Science Lab Investigation — a full murder-mystery investigation for the whole class
• Gloves W/o Powder Nitrile Disposable — avoids contaminating test surfaces and protects skin
• Safety Goggles — eye protection while reagents are handled

See more forensic and chemistry kits in our Chemistry Lab Equipment category.

Frequently Asked Questions

How many tests does one kit provide?
Each Gunshot Residue Presumptive Test Kit contains instructions and enough materials for 30 tests, so a class can run each sample alongside a clean-surface control and still have tests left for repeats.

What does the Gunshot Residue Presumptive Test Kit detect?
The Gunshot Residue Presumptive Test Kit indicates nitrates and lead, two substances associated with a discharged firearm, through a rapid colour change in two separate parts of the test.

Does a positive result prove a firearm was discharged?
No. The Gunshot Residue Presumptive Test Kit is a screening test, so a positive result is only an indication. Nitrates and lead can come from other sources, and firm conclusions need confirmatory laboratory analysis.

Can the kit be used for real casework?
The Gunshot Residue Presumptive Test Kit is offered as a presumptive screening test for teaching and training. Evidence in real investigations must be examined by a forensic laboratory using confirmatory methods.

Is it suitable for school students?
The Gunshot Residue Presumptive Test Kit can be used in supervised chemistry and forensic science lessons. Teachers should read the instructions and prepare a risk assessment beforehand, with gloves and eye protection for every student.

What is the shelf life of the kit?
The shelf life of the Gunshot Residue Presumptive Test Kit depends on the chemicals, their grade and storage conditions; ask us for the expiry date of the batch you are quoted before ordering stock for later terms.

Who supplies the Gunshot Residue Presumptive Test Kit?

Hoffman Voltameter Stand (Product Code: SLE/CH/146) is a metal stand with a support clamp, made to hold a Hoffman’s voltameter securely upright during electrolysis experiments, and it is supplied with a 600 mm rod. A Hoffman’s voltameter is tall glassware, so a dedicated stand keeps it steady and vertical while students watch gas collect and read the volumes. Chemistry and physics teachers, lab assistants and demonstrators use it wherever electrolysis of water is taught, and it is a sensible companion purchase for anyone sourcing electrolysis apparatus in India. The stand is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

In the classic demonstration, water made conductive with a little acid or salt is electrolysed in the Hoffman’s voltameter: hydrogen collects above one electrode and oxygen above the other, with roughly twice as much hydrogen as oxygen by volume. For those volumes to be read fairly, the side tubes must stand truly vertical and must not shift when the taps are opened or the leads are connected. The support clamp holds the voltameter in that position, and the 600 mm rod gives enough height to set the apparatus at a comfortable viewing level on the bench.

Stand the base on a level bench, fit the rod, then close the clamp gently around the voltameter — firm enough to hold it, never so tight that it stresses the glass. Route the electrical leads so they cannot catch on the stand, and wipe away any spilled electrolyte promptly to protect the metal parts. Schools in India equipping a chemistry lab for class demonstrations will find that ordering the stand with the voltameter avoids improvised clamping on general-purpose retort stands.

Manufacturer

The stand is manufactured by ScienceLab, the trading name of Jain Scientific Equipments Private Limited, which produces metal stands, clamps and teaching apparatus in Ambala, Haryana. Because it is made for use with the Hoffman’s voltameter, buyers can source the stand and the glassware from the same maker and receive them together, whether the order is for a school in India or for international markets. Visit our company profile to learn more.

Related Laboratory Equipment

An electrolysis demonstration also needs the voltameter itself, a power source and a way to watch the current; these items complete the set-up.

Hotplate & Magnetic Stirrer (Product Code: SLE/LHP/06) heats and stirs a solution at the same time on a 135 mm stainless steel work plate with a ceramic coating that resists corrosion. A DC brushless motor drives the stirring from 0-1500 rpm, heating runs from room temperature to 340 °C, and a separate safety circuit automatically stops heating when the temperature reaches 350 °C. Chemistry, biology and pharmacy labs use this hot plate magnetic stirrer India wide for dissolving, mixing and preparing solutions of up to 20 L of water. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

Drop a PTFE-coated stirrer bar into the beaker or flask, centre the vessel on the plate and raise the speed slowly until a steady vortex forms without splashing. Because the variable speed motor is designed to hold a constant speed as the load changes, the stirring rate stays steady even as a solid dissolves or a solution thickens, and strong magnetic coupling keeps the bar at the bottom of the vessel instead of jumping. Typical jobs include making up culture media and buffers, dissolving salts for standard solutions, and keeping a suspension uniform during a titration or precipitation.

As a laboratory magnetic stirrer in India teaching and QC labs, it is simple to operate with scale-marked knobs for speed and temperature. Set temperature with a thermometer in the liquid for accurate work, keep the enclosed IP42 housing away from standing liquid, and switch heating off before lifting the vessel so the plate is not left heating empty.

Manufacturer

Jain Scientific Equipments Private Limited supplies this stirrer under its ScienceLab brand from Ambala, Haryana. Institutional buyers can reference the company's MSME registration (Udyam UDYAM-HR-01-0003714, major activity manufacturing) and, for overseas orders, its DGFT Importer-Exporter Code AAECJ8618A. Read more on the company profile.

More heaters are listed in our Hot Plates category.

Frequently Asked Questions

What is the largest volume it can stir?
The maximum stirring quantity is 20 L of water. Thicker liquids need lower volumes and a suitable bar length, up to a maximum bar length of 80 mm.

What happens if the plate overheats?
A separate safety circuit automatically stops heating when the temperature reaches 350 °C, independent of the normal heating range of RT-340 °C.

Does it show temperature and speed digitally?
No, both speed and temperature are shown on scales around the control knobs. If you need a digital readout and PID control, see the Pro model.

Its moulded stainless steel casing, digital display and socket for an external temperature sensor let it display and control the actual liquid temperature, which is why it is used in chemical synthesis, physical and chemical analysis and bio-pharmaceutical work. Labs looking for a magnetic stirrer India researchers can rely on for repeatable settings will find it set up for clamped, sensor-controlled experiments. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

The Pro model is built for experiments that need a clamped set-up. Screw a retort rod into the integral fitting, or slide a standard retort base under the unit, and you can hold a condenser, thermometer or sensor directly over the vessel without a separate stand crowding the bench. With an external sensor in the liquid, the PID control works to the real solution temperature, which makes it well suited to syntheses at a set temperature, enzyme or dissolution studies, and preparing media that must not overheat.

In pharmacy college lab equipment lists and research labs alike, the low 55 mm height and the option to store units on their side save space between sessions. After switching off, watch the hot warning light: it remains active even when the unit is unplugged, so do not pack it away or touch the plate until the light indicates it is safe.

Liebig Condenser (Product Code: SLE/CH/148) is a straight, water-cooled condenser in borosilicate glass, with the inner tube integral with the body and a 200 mm jacket length. Its narrow jacket keeps the cooling water flowing close to the inner tube for efficient cooling, so hot vapour passing through is turned back into liquid quickly during distillation or reflux. School chemistry labs, college practical rooms and teaching laboratories use it as a standard part of their glassware, and it is a common requirement for buyers looking for a Liebig condenser in India. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala.

Specifications

Typical Use

In a simple distillation the condenser is clamped at a downward slope between the still head and the receiver, so condensed liquid runs out of the lower end into the collecting flask. Cooling water goes in at the lower connection and out at the upper one, which keeps the jacket completely full and gives the best cooling along the full 200 mm length. Because the inner tube is integral with the body, there is no separate seal between tube and jacket that could loosen or leak with repeated heating.

Clamped vertically above a boiling flask, the same unit works as a reflux condenser in the lab, returning condensed solvent to the reaction so it can be heated for longer without boiling dry. Start the water flow before switching on the heat, keep the flow steady rather than fierce, and hold the condenser with a clamp around the middle of the jacket. Let the glass cool before draining and dismantling, and never run cold water through a condenser that has been heated while dry.

Manufacturer

ScienceLab is the name under which Jain Scientific Equipments Private Limited, an Ambala, Haryana manufacturer of laboratory glassware and teaching apparatus, is known to customers. A Liebig condenser is also part of the company’s Fractional Distillation Assembly, so labs using that set can order a spare from the same source after checking the joint size with us. Institutions in India and international markets can find more on our company profile.
