Benzene 250 ml (Product Code: SCI-467/198) is an analytical reagent grade aromatic hydrocarbon used as a non-polar solvent and as the reference aromatic compound in college organic chemistry and research laboratories. Because benzene is a recognised carcinogen and highly flammable, it is meant for supervised advanced work rather than school classes; this listing is a 250 ml bottle supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India.

Specifications

What Is Benzene Used For?

Benzene is the textbook aromatic compound. Set beside an alkene, it does not decolourise bromine water under ordinary conditions, which illustrates the unusual stability of the aromatic ring. College and research laboratories also use it as a non-polar solvent for extraction and recrystallisation, and as the solvent in freezing-point depression experiments that estimate the molar mass of an organic solute.

Benzene vapour is harmful, heavier than air and highly flammable, so dispense it only inside a fume cupboard, well away from flames and hot plates, while wearing goggles and chemical-resistant gloves. For routine solvent work, many teaching labs now choose less hazardous alternatives such as cyclohexane and keep benzene for the few experiments that genuinely need it.

What to Specify When Ordering

• Product code SCI-467/198 and the number of 250 ml bottles.
• Whether a less hazardous solvent such as cyclohexane could serve your method instead.
• The delivery location, since flammable solvents need suitable shipping arrangements.

Supplier

Benzene 250 ml is sourced by Jain Scientific Equipments Private Limited, trading as ScienceLab, for colleges, universities and research laboratories in India and international markets. It is supplied with an MSDS so the chemical store holds the hazard, storage and first-aid information needed for a carcinogenic solvent, and it can share an enquiry with spill kits and glassware.

Company details are on the ScienceLab company profile.

Bromitimol Blue (Product Code: SCI-469/199) is an analytical reagent grade acid–base indicator dye, widely spelled bromothymol blue, used to show pH changes close to neutral in titrations and in carbon dioxide, photosynthesis and respiration experiments in school and college laboratories. Chemistry and biology teachers prepare indicator solution from this 25 g pack, which is supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

Specifications

What Is Bromothymol Blue Used For?

Bromothymol blue is yellow in acid, blue in alkali and green around neutral, so it suits titrations whose end point falls near neutral, such as a strong acid against a strong base. It is also a quick way to check whether water samples or simple buffers are slightly acidic or slightly alkaline, and it earns a place in any acid base indicator kit used for comparing indicators.

In biology, blowing exhaled air through a dilute blue solution turns it green and then yellow as dissolved carbon dioxide forms carbonic acid. With pondweed sealed in indicator solution, tubes kept in light drift back towards blue as photosynthesis removes carbon dioxide, while tubes kept dark turn yellow from respiration. Dissolve the solid in a little ethanol or very dilute alkali before diluting with water.

Supplier

The indicator is sourced and supplied by Jain Scientific Equipments Private Limited under its ScienceLab name to schools, colleges and laboratories in India and international markets, with the MSDS enclosed. Because a small amount of solid makes a large volume of working solution, institutions often order it with other indicators, dropper bottles and pH papers on the same enquiry.

Company information is on the ScienceLab profile.

Bromine (Water Bromine) (Product Code: SCI-471/200) is an analytical reagent grade solution of bromine in water used to test for unsaturation, compare the reactivity of the halogens and identify phenols and aromatic amines in school and college chemistry laboratories. Teachers and lab assistants dispense it in small portions for test-tube reactions, and this listing is a 100 ml pack supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Is Bromine Water Used For?

The orange-brown colour of bromine water disappears when it is shaken with an alkene, but stays when it is shaken with an alkane such as cyclohexane in the dark — the standard school test for a carbon–carbon double bond. Phenol and aniline also remove the colour and give a white precipitate, which helps identify them. Added to potassium iodide solution, bromine displaces iodine and turns the liquid brown, showing that bromine is more reactive than iodine.

Bromine vapour irritates the eyes and lungs, so dispense the solution in a fume cupboard while wearing goggles and gloves. The solution slowly loses bromine to the air and weakens, so keep it tightly stoppered in a cool, dark chemistry reagent cabinet, away from metals and reducing agents.

What to Specify When Ordering

• Product code SCI-471/200 and the number of 100 ml packs.
• The bromine concentration your tests require, as the listing does not state it.
• The delivery location, so packing and shipping of the solution can be planned.

Potassium Bromide (Product Code: SCI-473/201) is an analytical reagent grade inorganic salt used as a source of bromide ions in halide tests and halogen displacement experiments, and for pressing sample discs in infrared spectroscopy, in school, college and university laboratories. The 200 g pack serves both qualitative analysis classes and instrumental labs, and it is supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India.

Specifications

What Is Potassium Bromide Used For?

With acidified silver nitrate, a bromide solution gives a cream precipitate of silver bromide that dissolves in concentrated ammonia but not in dilute ammonia, which separates it from chloride and iodide in qualitative analysis. Add chlorine water and the solution turns orange as bromine is displaced, showing that chlorine is the more reactive halogen. These tests make potassium bromide a standard entry in any salt analysis kit a school or college assembles.

In instrumental labs, dry potassium bromide is ground with a little of a solid sample and pressed into a clear disc for infrared spectroscopy, because the salt itself is transparent across the usual infrared range. The salt picks up moisture, which shows up in spectra, so keep the container tightly closed and hold working stock in a desiccator.

What to Specify When Ordering

• Product code SCI-473/201 and the number of 200 g packs.
• Whether the salt is for wet qualitative analysis or for infrared sample discs.

Butanol-1 (Product Code: SCI-475/202) is an analytical reagent grade primary alcohol, also called 1-butanol or n-butanol, used to compare the alcohols of a homologous series, to prepare esters and as a solvent in paper chromatography in school and college chemistry laboratories. Chemistry teachers and biology departments running amino acid chromatography use this 100 ml pack, which comes with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Is Butanol Used For?

Burned in a spirit burner beneath a copper calorimeter, butanol raises the water temperature more per gram of fuel than methanol or ethanol, letting students link energy of combustion to chain length. It only partly mixes with water, unlike ethanol, which shows how a longer carbon chain lowers solubility. Warmed with acidified potassium dichromate it turns the orange solution green, the test for a primary alcohol, and with ethanoic acid and a few drops of concentrated sulfuric acid it forms the fruity-smelling ester butyl ethanoate.

Mixed with ethanoic acid and water, butanol makes the classic running solvent for separating amino acids on paper, which is why it belongs in a paper chromatography kit for school or college biology. It is a flammable liquid with a strong odour, so use it in a well-ventilated room away from flames, wear goggles, and keep the bottle capped.

Supplier

Jain Scientific Equipments Private Limited supplies Butanol-1 under the ScienceLab name to schools, colleges and research laboratories in India and international markets, sourcing it for teaching use and dispatching it with its MSDS.

Cyclohexane (Product Code: SCI-477/203) is an analytical reagent grade cycloalkane solvent used to dissolve non-polar substances and to show how saturated hydrocarbons behave in school and college chemistry laboratories. Chemistry teachers and lab technicians order it as a 100 ml pack that comes with its MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India for teaching and research labs.

Specifications

What Is Cyclohexane Used For?

In teaching labs, cyclohexane is the standard example of a saturated ring hydrocarbon. Shaken with bromine water away from strong light, it leaves the orange colour in place (the bromine simply moves into the upper organic layer), while an alkene decolourises it quickly, so students see the difference between saturated and unsaturated compounds side by side. Its puckered six-membered ring is also a favourite for conformation lessons with molecular models.

As a solvent, cyclohexane dissolves oils, fats, waxes and iodine and floats on water, which makes it handy for simple extractions and for recrystallising non-polar solids. It is highly flammable and its vapour spreads easily, so measure it out in a chemical fume cupboard away from burners, keep the bottle capped between uses and follow the handling advice in the MSDS.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab, supplies Cyclohexane together with the glassware and safety items that solvent practicals call for, so a chemistry store can be restocked through a single enquiry. The company is based in Ambala, Haryana, and serves schools, colleges, research laboratories and dealers across India and international markets. Company background is on the ScienceLab profile page.

Frequently Asked Questions

What pack size is Cyclohexane supplied in?
Cyclohexane (SCI-477/203) is supplied in a 100 ml pack of analytical reagent grade, together with its MSDS. If your laboratory needs several packs for a class set or a larger store, state the number of packs in your enquiry and we will quote for that quantity.

Why is Cyclohexane used as a control in the bromine water test?
Cyclohexane is a saturated hydrocarbon, so it has no double bond for bromine to add across and the orange colour remains when the two are shaken together without strong light. Running it beside an alkene shows students clearly how the bromine water test identifies unsaturation.

How should Cyclohexane be stored in a school laboratory?
Store Cyclohexane in its tightly closed bottle in a cool, well-ventilated flammables area, away from heat, sparks, open flames and oxidising agents. Keep the MSDS supplied with the pack near the store so staff can check handling, spill and first-aid guidance quickly.

What is the shelf life of Cyclohexane?

Sodium Dihydrogen Phosphate (Product Code: SCI-481/205) is an analytical reagent grade acidic phosphate salt used to prepare phosphate buffers for pH, enzyme and biochemistry practicals in school, college and research laboratories. Also known as monosodium phosphate, it comes as a 100 g pack with its MSDS for teachers who make up their own pH buffer solution in the lab. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Sodium Dihydrogen Phosphate Used For?

The most common job for sodium dihydrogen phosphate is making phosphate buffers. Mixed with disodium hydrogen phosphate in different proportions, it gives solutions that hold a steady pH close to neutral, which is why it appears in practicals on enzyme activity, the effect of pH on catalase or amylase, and the preparation of wash solutions in biology labs. Students can check each buffer with a pH meter and see how little the reading moves when a few drops of acid or alkali are added.

It also serves in qualitative analysis as a source of phosphate ions: acidified with nitric acid and warmed with ammonium molybdate, a phosphate solution gives a yellow precipitate. Make stock solutions to an exact volume in a volumetric flask with distilled water, label them with the date, and keep the solid tightly closed because the salt picks up moisture from humid air.
