Barium Sulphate (Product Code: SCL368/086) is a dense white, practically insoluble salt supplied as an analytical reagent in a 500 gm pack, used to demonstrate precipitation and as a reference sample for the sulphate test. Chemistry and biochemistry teachers keep it so students can compare their own precipitate with the known compound. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a useful addition to a salt analysis kit for school practicals.

Specifications

What Is the Barium Sulphate Used For?

In the sulphate test, barium chloride solution is added to an acidified solution containing sulphate ions, and a white precipitate of barium sulphate forms. Keeping a pure sample on the shelf lets students compare the look of their precipitate with the known compound, check that it does not redissolve in dilute acid, and practise filtering and drying an insoluble solid. It is equally useful in college inorganic chemistry and biochemistry classes.

Barium sulphate also gives teachers a practical way to discuss why some compounds pass through the body unabsorbed — the reasoning behind the barium meal used in medical imaging. This pack, however, is a laboratory reagent for teaching and analysis, not a medical product. Weigh it in a clean, dry area, avoid raising dust, and follow the supplied MSDS for storage and disposal.

Benedicts Reagent (Test Of Glucose) (Product Code: SCL370/088) is a blue, copper-based analytical reagent in a 500 ml pack, used to detect glucose and other reducing sugars in food tests and biochemistry practicals. On heating with a sample, its colour shifts from blue towards brick-red as the sugar content rises, which makes it the staple Benedict solution for school practicals in India. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Benedict's Reagent Used For?

To test a sample, students mix it with Benedict's reagent in a test tube and heat the tube in a boiling water bath for a few minutes. A reducing sugar such as glucose, fructose, maltose or lactose reduces the copper ions, and the mixture moves from blue through green, yellow and orange to a brick-red precipitate — the further along that sequence, the more sugar is present. Because the result is semi-quantitative, classes can rank fruit juices, milk or germinating-seed extracts by their reducing-sugar content.

Always run a known glucose solution as a positive control and water as a negative control, and keep the heating time identical for every tube so colours can be compared fairly. As a single ready-mixed solution, the reagent suits large classes where many groups test at once. Keep the bottle capped between sessions and follow the supplied MSDS.

Supplier

This reagent is supplied under ScienceLab, the trading name of Jain Scientific Equipments Private Limited, whose operations are based in Ambala, Haryana, India. Alongside reagents, the company supplies the test tubes, beakers and sugars used in food-test lessons to biology, chemistry and physics laboratories in India and international markets. Our company profile gives more background.

Related Biology Lab

Useful companions for a reducing-sugar practical:

• Glucose — a known reducing sugar for the positive control tube.
• Sucrose — a non-reducing sugar that shows students a negative result.
• Test Tubes (With Rim) — for heating sample and reagent together.
• Beaker — holds the boiling water bath for the tubes.
• Fehling' S Sol A (Test Of Sucrose) — an alternative reducing-sugar test for comparison.

For more reagents and apparatus, browse the Biology Lab range.

Frequently Asked Questions

What does a positive result with Benedicts Reagent (Test Of Glucose) look like?
After heating, Benedicts Reagent (Test Of Glucose) turns from blue to green, yellow, orange or brick-red depending on how much reducing sugar the sample holds. A mixture that stays blue shows that no reducing sugar was detected.

Will Benedicts Reagent (Test Of Glucose) detect sucrose?
Not directly, because sucrose is a non-reducing sugar. Boil the sucrose sample with dilute acid and neutralise it; the glucose and fructose released will then give a positive colour change with Benedicts Reagent (Test Of Glucose).

How is Benedicts Reagent (Test Of Glucose) different from Fehling's solution?
Benedicts Reagent (Test Of Glucose) is a single, milder alkaline solution ready to use, whereas Fehling's solutions A and B are stored separately and mixed just before the test, which makes Benedict's simpler for large classes.

What volume of Benedicts Reagent (Test Of Glucose) is supplied?
Each pack of Benedicts Reagent (Test Of Glucose) contains 500 ml of analytical reagent, supplied with an MSDS. Only a small volume is needed per test tube, so a single pack serves many student tests.

What is the shelf life of Benedicts Reagent (Test Of Glucose)?
The shelf life of Benedicts Reagent (Test Of Glucose) depends on the reagent, its grade and storage conditions, so no fixed period is stated. Ask us for the expiry date of the batch you are quoted, and store it capped away from sunlight.

Who supplies Benedicts Reagent (Test Of Glucose) for several schools?

Biuret Reagent (Protein Test) (Product Code: SCL371/089) is an alkaline, copper-containing analytical reagent in a 125 ml pack, used to detect proteins by turning violet when peptide bonds are present. Biology teachers use it for food tests and enzyme lessons, and because the test runs at room temperature it suits younger classes as well as introductory biochemistry. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a compact item for any biology lab setup in a school.

Specifications

What Is the Biuret Reagent Used For?

The biuret test needs no heating: add the reagent to the sample in a test tube, shake gently and wait briefly. Copper ions in the alkaline reagent bind to peptide bonds, and the pale blue mixture turns violet or purple if protein is present. Egg white, milk and extracts of pulses or germinating seeds give clear positives, so a class can compare protein-rich and starch-rich foods in the same lesson or follow protein digestion in an enzyme experiment.

Set up a water blank beside the samples so students can judge the colour change against the unchanged blue. Because the reagent is alkaline, gloves and eye protection are advisable and spills should be wiped up promptly. The test is usually repeated across several sections of the same class, so keep the bottle capped between sessions.

Frequently Asked Questions

What colour shows protein with Biuret Reagent (Protein Test)?
Violet to purple. When Biuret Reagent (Protein Test) is mixed with a sample containing protein, copper ions bind to the peptide bonds and the pale blue mixture turns violet; if it stays blue, no protein was detected.

Does the test with Biuret Reagent (Protein Test) need heating?
No. Biuret Reagent (Protein Test) works at room temperature: add it to the sample, shake gently and wait briefly. That makes the protein test quicker and safer for younger students than the heated sugar tests.

Will Biuret Reagent (Protein Test) detect individual amino acids?
No. Biuret Reagent (Protein Test) reacts with peptide bonds, so free amino acids give a negative result. When amino acids themselves are the target, use a ninhydrin solution instead, which is also listed in our Biology Lab range.

Boric Acid (Product Code: SCL372/090) is a weak acid supplied as an analytical reagent in a 500 gm pack, used to prepare borate buffers such as TBE for DNA gel electrophoresis and to add boron to pollen-germination media. College biotechnology departments and school biology labs use it with the supplied MSDS on file. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as a routine buffer ingredient for any gel electrophoresis kit in India.

Specifications

What Is the Boric Acid Used For?

In the pollen-germination practical, students dust fresh pollen onto a drop of sugar solution containing a trace of boric acid on a cavity slide and watch pollen tubes emerge under the microscope; since boron supports pollen-tube growth, slides with and without it make a simple investigation. In college molecular biology, boric acid is weighed out with the other buffer components, dissolved in distilled water and checked on a pH meter before an electrophoresis run.

Weigh it on a clean, dry balance pan and close the container straight away, as the powder can cake if it absorbs moisture. Although it is only a weak acid, boric acid should never be treated as harmless: avoid swallowing it or inhaling the dust, keep it out of reach of young students, and follow the supplied MSDS for storage and disposal.

Cellulose Enzyme (DNA Separation) (Product Code: SCL373/091) is an enzyme preparation in a 100 ml pack used to digest the cellulose of plant cell walls during DNA isolation practicals. Listed as an analytical reagent and supplied with an MSDS, it lets students release DNA from onion, spinach or fruit tissue, which makes it a key item in a DNA extraction kit for schools in India. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Cellulose Enzyme Used For?

The textbook route to isolating DNA from plant material runs in stages: the tissue is ground, the cell walls are digested with a cellulose-degrading enzyme, proteins and RNA are removed with protease and ribonuclease, and the DNA is finally precipitated with chilled ethanol, where it appears as fine white threads that can be spooled onto a glass rod. This enzyme covers the cell-wall step, which is what makes onion, spinach or fruit usable in a classroom extraction for senior secondary and undergraduate biotechnology courses.

Enzymes are sensitive to heat and pH, so follow the incubation conditions in your practical manual and never add the enzyme to a hot mixture. Check the label and supplied MSDS for the recommended storage conditions, keep the bottle closed between uses, and draw from it with a clean pipette each time so the stock is not contaminated.

Chloroform (Chromatography) (Product Code: SCL375/092) is an analytical reagent grade organic solvent used as, or blended into, the mobile phase that separates plant pigments and other compounds in school and college chromatography practicals. It comes in a 500 ml pack with its MSDS, a practical refill for any paper chromatography kit school laboratories run. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Chloroform (Chromatography) Used For?

The best-known biology practical separates the pigments of a green leaf. A concentrated leaf extract is spotted near the base of a paper strip, the strip is hung in a closed jar over a shallow layer of solvent, and as the solvent rises the pigments travel different distances, leaving separate bands of carotenes, xanthophylls and chlorophylls. Chloroform-based solvent systems are also used in thin-layer chromatography of lipids and other non-polar compounds.

Chloroform vapour is harmful, so dispense it in a fume cupboard or a well-ventilated room and keep the jar lid on throughout the run, which also keeps the chamber saturated for sharper bands. Let teachers rather than students handle the stock bottle, store it tightly closed away from light and heat, and follow the MSDS for spills and waste. It sits comfortably on the reagent shelf of school chemistry lab equipment in India as well as in the biology room.

Cobalt Chloride (Product Code: SCL376/093) is an analytical reagent grade salt used to prepare blue-to-pink moisture indicator papers for detecting water in school and college biology practicals. Packed as 100 gm with its MSDS, it lets teachers make their own strips for comparing water loss from the two surfaces of a leaf, the base chemical of a home-made transpiration experiment kit in India's school labs. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Cobalt Chloride Used For?

To make indicator paper, strips of filter paper are soaked in cobalt chloride solution and dried until fully blue, then kept in a desiccator until needed. In the classic transpiration practical, one strip is held against the upper surface of a leaf and another against the lower surface, each covered with a glass slide and clipped in place. Students time how long each strip takes to turn pink and relate the difference to the number of stomata on each surface.

The same papers confirm that a colourless liquid is water, a routine test in botany and general science. Cobalt compounds are toxic and can irritate or sensitise skin, so prepare the solution and strips wearing gloves, avoid raising dust and wash hands afterwards. The solid readily takes up moisture from the air, so reseal the container quickly after weighing and keep it dry as the MSDS advises.

Supplier

ScienceLab is the trading name of Jain Scientific Equipments Private Limited, an Ambala, Haryana company that supplies laboratory reagents such as cobalt chloride together with glassware and teaching apparatus to schools, colleges and distributors. For vendor registration, the supplying company is Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597, GSTIN 06AAECJ8618A1ZT). Read our company profile for more.

See the complete Biology Lab range for further items.

Frequently Asked Questions

Why does Cobalt Chloride change colour?
Cobalt Chloride changes colour because the anhydrous salt is blue and the hydrated salt is pink. When it absorbs water it turns pink, and drying it again restores the blue colour, which is why it works as a simple moisture indicator.

How do I make test papers from Cobalt Chloride?
To make test papers from Cobalt Chloride, soak filter-paper strips in a cobalt chloride solution, dry them until evenly blue, and store them in a desiccator or sealed container. Wear gloves throughout and handle the finished strips with dry forceps.

How much does one pack of Cobalt Chloride contain?
One pack of Cobalt Chloride contains 100 gm of analytical reagent grade material, supplied with its MSDS. Only a small amount is needed to impregnate a batch of paper strips, so plan the number of packs by the classes that will run the practical.

Is Cobalt Chloride safe for school practicals?
Cobalt Chloride can be used in school practicals with care: it is toxic if swallowed and can sensitise skin. Teachers should prepare the solution and papers wearing gloves, and students should handle only the finished strips, following the MSDS.

How long does Cobalt Chloride keep?
The shelf life of Cobalt Chloride depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Because the salt absorbs moisture from the air, reseal the container quickly and store it somewhere dry.

Who supplies Cobalt Chloride?
Cobalt Chloride is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India. The company supplies it to schools, colleges and distributors in India and international markets, alongside the filter paper and glassware used for transpiration practicals.

Cobalt Chloride Paper (Product Code: SCL378/094) is an indicator test paper used to detect water in school and college practicals, most often to show the moisture given off by the upper and lower surfaces of a leaf. It lets students watch transpiration happen without any instrument, which makes it a simple piece of plant biology lab equipment for botany classes. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Key Details

What Is Cobalt Chloride Paper Used For?

Cobalt chloride papers are conventionally blue when dry and turn pink on contact with water. In the familiar classroom use, a dry strip is placed on the upper surface of a leaf and another on the lower surface, both covered with glass slides and clipped; the strip that turns pink first marks the surface losing more water, usually the underside where stomata are more numerous. It is an inexpensive addition to a transpiration experiment kit in India's school biology rooms.

Students can also touch a strip to droplets collected under a bell jar, or to an unknown colourless liquid, to confirm it is water. For clear results keep unused strips in a closed container or desiccator, handle them with dry forceps rather than fingers, and compare colours against a fresh dry strip. Wash hands after handling and keep the papers away from younger children.

Supplier

Cobalt Chloride Paper is offered by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. The company supplies teaching laboratories with test papers, reagents and apparatus for biology, chemistry and physics, and confirms pack details with each quotation request.
