Million's Reagent (Test Of Proteins) (Product Code: SCL403/0111) is the protein-test reagent more commonly spelled Millon's reagent, used to detect tyrosine-containing proteins in school and college biology practicals. Supplied as an analytical reagent in a 125 ml pack, it gives senior secondary and college students a second, more specific protein test to set beside the biuret test. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, with an MSDS.

Specifications

What Is Millon's Reagent Used For?

A few drops of the reagent are added to a small volume of protein solution, such as diluted egg white or milk, in a test tube. A precipitate forms, and on gentle warming it turns red, confirming a tyrosine-containing protein. Comparing egg albumin with gelatin, which contains very little tyrosine and reacts only weakly, helps students see that different protein tests detect different chemical features. Because only a few drops are needed per tube, one pack covers many practical groups, making it a sensible addition to the biology lab equipment schools in India use for biomolecule tests.

Millon's-type reagents are traditionally prepared from heavy-metal salts in acid, so check the MSDS supplied with this pack for its composition, hazards and disposal advice. The heating step is best done by the teacher or in a chemical fume cupboard, with goggles and gloves, and all used tube contents should be collected in a labelled waste container rather than poured down the sink.

Frequently Asked Questions

Is Million's Reagent (Test Of Proteins) the same as Millon's reagent?
Yes. Million's Reagent (Test Of Proteins) is the reagent used in Millon's test for proteins; "Million's" is simply the spelling used in the product name on this site, and enquiries under either spelling refer to the same item.

What does a positive result with Million's Reagent (Test Of Proteins) look like?
With Million's Reagent (Test Of Proteins), a precipitate that turns red on gentle warming indicates a protein containing tyrosine. No red colour means tyrosine is absent or present only in traces, as with gelatin compared with egg albumin.

How is Million's Reagent (Test Of Proteins) different from the biuret test?
The biuret test responds to the peptide bonds present in all proteins, while Million's Reagent (Test Of Proteins) responds specifically to the amino acid tyrosine. Running both tests side by side gives students a fuller picture of a protein sample.

How much reagent is in one pack of Million's Reagent (Test Of Proteins)?
Each pack of Million's Reagent (Test Of Proteins) holds 125 ml of analytical reagent grade reagent and includes an MSDS. Only a few drops are needed per test tube, so one pack covers many practical groups.

Ninhydrin Sol (Test Of Amino Acids) (Product Code: SCL404/0112) is a ninhydrin solution used to reveal amino acids in spot tests and on paper chromatograms in biology and biochemistry labs. Listed as analytical reagent grade in a 125 ml pack, it develops a deep purple colour with free amino acids on warming, which makes it the developing reagent in a paper chromatography kit for school biochemistry. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, with an MSDS in each pack.

Specifications

What Is Ninhydrin Solution Used For?

In paper chromatography, students spot a mixture of amino acids, or a digested protein sample, on chromatography paper and run it in a solvent inside a closed jar. Once the paper is dry, it is sprayed or dipped in ninhydrin and gently warmed; purple spots appear where each amino acid has travelled, so students can measure distances and calculate Rf values. As a simple tube test, a few drops added to a sample and heated in a water bath show whether amino acids are present, which is handy for demonstrating that a protease has broken a protein down.

Ninhydrin reacts with the amino acids in skin, so it will leave purple stains on fingers; wear gloves and handle chromatograms by the edges. Spray only in a ventilated area, keep the bottle closed when not in use and check the MSDS for the solvent and any flammability warnings. Labs ordering from a chemistry consumables supplier in India usually buy it together with chromatography paper and jars.

Supplier

Ninhydrin solution is supplied by Jain Scientific Equipments Private Limited, trading as ScienceLab and located in Ambala, Haryana, India. The company sources reagents for biology and chemistry practicals, so chromatography paper, jars and developing reagents can be ordered together. See our company profile for more.

• Chromatography Paper No. 1 — paper on which amino acids are separated before spraying
• Chromatographic Jar — closed jar for running the solvent up the paper
• Protease Enzyme (DNA Separation) — breaks proteins into amino acids that ninhydrin can detect
• Water Bath — controlled warming for tube tests
• Molecular Model Set, 20 Amino Acid Collection — models to explain the structures being detected

More biomolecule reagents are listed in the Biology Lab category.

Frequently Asked Questions

What colour does Ninhydrin Sol (Test Of Amino Acids) give with amino acids?
Ninhydrin Sol (Test Of Amino Acids) gives a purple to blue-violet colour with most amino acids after warming. A few, such as proline, give a yellow colour instead, which students can note when identifying spots on a chromatogram.

Does Ninhydrin Sol (Test Of Amino Acids) detect whole proteins?
Ninhydrin Sol (Test Of Amino Acids) reacts mainly with free amino groups, so it is most useful for amino acids and digested protein samples. For intact proteins, the biuret test is the more suitable classroom test.

Is Ninhydrin Sol (Test Of Amino Acids) ready to spray on chromatograms?
Ninhydrin Sol (Test Of Amino Acids) is supplied as a solution in a 125 ml pack. Whether to use it directly or dilute it depends on your method, so follow your practical manual and the MSDS supplied with the pack.

Why does Ninhydrin Sol (Test Of Amino Acids) stain fingers purple?
Ninhydrin Sol (Test Of Amino Acids) reacts with the amino acids naturally present on skin, leaving purple marks that fade over a few days. Wearing gloves and handling chromatograms only by their edges prevents both stained fingers and stray spots.

What is the shelf life of Ninhydrin Sol (Test Of Amino Acids)?
The shelf life of Ninhydrin Sol (Test Of Amino Acids) depends on the chemical, its grade and storage conditions, so no fixed period is quoted. Ask us for the expiry date of the batch you are quoted, and store it tightly closed away from heat and light.

Nitric Acid (Conc) (Product Code: SCL406/0113) is concentrated nitric acid of analytical reagent grade used for the xanthoproteic protein test and other staff-supervised tests in biology and chemistry laboratories. School and college departments stock it in a 500 ml pack with an MSDS, mainly to show students that proteins containing ring-structured amino acids turn yellow with the acid. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to school chemistry and biology labs.

Specifications

What Is Concentrated Nitric Acid Used For?

For the xanthoproteic test, the teacher adds a small amount of concentrated nitric acid to egg-white solution in a test tube and warms it gently; a yellow colour develops. After cooling, adding an alkali such as ammonia solution deepens the colour to orange, completing the test. Students often recognise the same reaction from the yellow marks nitric acid leaves on skin, which is itself a protein reaction and a reminder of why gloves and care are needed.

Concentrated nitric acid is a strong oxidising acid that gives off irritating fumes, so it should be opened and dispensed only by teachers or trained staff in a fume cupboard, with goggles, face protection and an apron. Store the bottle upright in a cool, dark acid cabinet, separate from alcohols, organic materials and other reactive chemicals. Keep neutralising spill materials ready and follow the MSDS for first aid and disposal.

Potassium Hydroxide (Pellets) (Product Code: SCL410/0115) is an analytical reagent grade alkali in pellet form, used in biology labs to absorb carbon dioxide in respiration and photosynthesis experiments. It comes in a 500 g pack supplied with an MSDS for safe handling. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, to schools, colleges and biology departments.

Specifications

What Is Potassium Hydroxide Used For in Biology Experiments?

In a simple respirometer, germinating seeds or small invertebrates are sealed in a tube with a little potassium hydroxide solution, which absorbs the carbon dioxide they release; movement of a coloured drop along the capillary then shows how much oxygen the organisms take up. In Moll's half-leaf experiment, potassium hydroxide in the flask removes carbon dioxide from the air around part of a leaf, and a later starch test shows that photosynthesis stopped where carbon dioxide was absent.

Prepare only the amount of solution needed, keep it separated from living material with cotton wool or a gauze platform, and label it clearly as corrosive. Close the pellet container immediately after use, because potassium hydroxide absorbs moisture and carbon dioxide from the air and loses strength. It is a standard reagent in a biology lab setup for schools in India.

Supplier

ScienceLab, the trading name of Jain Scientific Equipments Private Limited, sources Potassium Hydroxide (Pellets) for biology and chemistry departments and ships each pack with its MSDS. Biology teachers can order it together with lime water, distilled water and other practical items on one enquiry, for delivery in India or international markets.

Protease Enzyme (DNA Separation) (Product Code: SCL417/0118) is a protein-digesting enzyme used to strip proteins away from DNA in classroom DNA separation and enzyme practicals. Supplied in a 500 g pack of listed analytical reagent grade with an MSDS, it is a natural fit for any biotechnology lab kit in India built around DNA work. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is the Protease Enzyme Used For?

In a classroom DNA separation, crushed fruit, onion or cheek cells are mixed with a salt and detergent solution to open the cells. A small amount of protease is then stirred in and the mixture is left to stand, often in a warm water bath, while the enzyme digests the proteins that hold DNA in a tightly packed form. After filtering, chilled alcohol is poured gently down the side of the tube, and the freed DNA gathers at the boundary as a white, stringy mass that students can lift out.

Protease also makes a clear stand-alone demonstration of enzyme action. Added to a cloudy egg-white suspension or to milk, it gradually changes the protein, and students can confirm the breakdown by showing a weaker biuret result or a stronger ninhydrin result as digestion proceeds. Setting tubes at different temperatures and including a boiled-enzyme control turns the activity into a complete investigation, similar to those in an enzyme activity kit for biology classes.

Supplier

This enzyme is supplied by Jain Scientific Equipments Private Limited, whose trading name is ScienceLab. The Ambala, Haryana company sources enzymes and other reagents for biology and biotechnology practicals, so a DNA isolation session can be ordered together with its glassware and water bath. Visit the company profile for more.

Frequently Asked Questions

Why is Protease Enzyme (DNA Separation) added when isolating DNA?
DNA in cells is bound to proteins, and Protease Enzyme (DNA Separation) digests those proteins so the DNA is released more completely and separates out in chilled alcohol with less protein contamination.

How is Protease Enzyme (DNA Separation) different from lipase?
Protease Enzyme (DNA Separation) acts on proteins, whereas lipase acts on fats and membrane lipids. Many school DNA separation methods use both enzymes, each for a different step, so the two are often ordered together.

What quantity does one pack of Protease Enzyme (DNA Separation) contain?
Each pack of Protease Enzyme (DNA Separation) contains 500 g of enzyme, listed as analytical reagent grade and supplied together with an MSDS covering safe handling, storage and first aid in the laboratory.

Smith's Reagent (Product Code: SCL419/0119) is an analytical reagent grade laboratory reagent used for qualitative tests in school, college and paramedical biology and physiology practicals. It comes in a 125 ml pack with a Material Safety Data Sheet (MSDS), so the lab in-charge has handling and storage guidance on file from the first day. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier to institutions across the country.

Specifications

What Is Smith's Reagent Used For?

In physiology and clinical biochemistry teaching, the name Smith's reagent is generally associated with Smith's test, a quick qualitative screen for bile pigments in urine. A small volume of the sample is placed in a clean test tube and the reagent is run slowly down the inside wall so that it settles as a separate layer; a green ring at the junction of the two layers is read as a positive result, while no ring suggests the pigments are not present at a detectable level. Because recipes and names vary between syllabi, please confirm with us that this reagent matches the procedure in your practical manual before you order.

For reliable readings, run a known negative sample next to the unknown, tilt the tube while pouring so the layers do not mix, and read the result against a white background within a few moments. Colleges that source their biology lab equipment in India from one supplier often add this reagent to the same order as test tubes, droppers and the other urine-analysis reagents, which keeps a practical session complete and consistent from bench to bench.

Sodium Hypobromite (Product Code: SCL423/0122) is an alkaline oxidising reagent used to detect urea in urine and in prepared urea solutions during biology and physiology practicals. Supplied in a 500 ml pack of analytical reagent grade with an MSDS, it releases a visible stream of gas bubbles when urea is present, which makes it a favourite demonstration in lessons on excretion. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier for schools and colleges.

Specifications

What Is Sodium Hypobromite Used For?

The classic class demonstration is simple: a little urine, or a urea solution used as a positive control, is taken in a test tube and the hypobromite reagent is added. Urea is oxidised and nitrogen gas is released, so brisk effervescence indicates urea, while a tube of plain water shows no bubbles. In older quantitative work the same reaction was carried out in a closed ureometer, where the volume of gas collected was used to estimate urea content, and some college physiology manuals still describe that method.

Handle the reagent as an alkaline oxidiser: wear eye protection, keep it away from acids (acidifying hypobromite can release bromine), and work on a tray so spills stay contained. Hypobromite reagents tend to lose strength once opened, so run a urea control before the class and keep the bottle closed between uses. Schools planning a practical session on excretion often pair this reagent with the urease and phenol red test, and buying both from one school biology lab equipment supplier in India keeps the set consistent.

Supplier

Sodium Hypobromite is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, and sources reagents, glassware and teaching apparatus for education and research laboratories. For vendor registration, the supplying company is Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597, GSTIN 06AAECJ8618A1ZT). Background on the company is on our company profile page.

• Test Tubes (With Rim) — clear tubes in which the effervescence is easy for the whole group to see
• Safety Goggles — eye protection while dispensing an alkaline oxidising reagent

More reagents and apparatus are listed in the Biology Lab category.

Frequently Asked Questions

Is Sodium Hypobromite the same as "sodium hypobromide"?
Yes. "Sodium hypobromide" is a common misspelling; the reagent used in urea tests is Sodium Hypobromite. If your manual names a specific recipe or strength, send it through the contact page and we will confirm whether this pack matches.

What does a positive result with Sodium Hypobromite look like?
With Sodium Hypobromite, brisk bubbling of nitrogen gas after the reagent is added indicates urea. Always compare the sample with a water blank and a urea control so students can clearly see the difference between a positive and a negative tube.

How much Sodium Hypobromite is supplied, and in what grade?
One pack of Sodium Hypobromite contains 500 ml of analytical reagent grade solution, and an MSDS is supplied with it covering hazards, safe storage, first aid and disposal for the laboratory.

What is the shelf life of Sodium Hypobromite?
The shelf life of Sodium Hypobromite depends on the chemical, its grade and storage conditions, so no blanket period is quoted. Ask us for the expiry date of the batch you are quoted, and check an opened bottle with a urea control before each practical.

How should Sodium Hypobromite be stored?
Store Sodium Hypobromite tightly closed in a cool, dark place, away from acids and organic material, because acidifying a hypobromite can release bromine. Keep the bottle on a tray so any spill of this alkaline oxidiser stays contained.

Who supplies Sodium Hypobromite?
Sodium Hypobromite is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges and distributors, often together with urease powder, phenol red and urea so that a complete excretion practical can be ordered at once.

Can Sodium Hypobromite be shipped outside India?

Silver Nitrate (AgNO3) (Product Code: SCL436/0124) is an analytical reagent grade silver salt used to detect chloride ions in biology, physiology and chemistry practicals. Packed in a compact 20 g quantity that suits the small amounts teaching labs need, it is the starting point for the silver nitrate solution school labs in India use for chloride tests on urine, sweat, plant sap or tap water. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, with an MSDS.

Specifications

What Is Silver Nitrate Used For?

In biology and physiology practicals, dilute silver nitrate is the standard test for chloride ions in urine, sweat, saliva, plant sap or tap water: silver chloride forms a white, curdy precipitate that darkens slowly in light. The same reaction explains why students are asked to rinse glassware with distilled water first, since traces of tap water can give a false positive. At college level, silver compounds are also used in histology to outline cell boundaries and fibres, where the silver deposits appear dark under the microscope.

Preparing your own silver nitrate solution from this 20 g pack lets the lab make only as much as each practical needs. Dissolve it in distilled water, store the solution in an amber bottle away from light, and label it clearly. Silver nitrate leaves brown-black marks on skin, benches and clothing that appear after a few hours, so gloves and careful pipetting are worth insisting on; it is also an oxidiser, so keep it away from organic material and combustibles.

Supplier

Silver Nitrate (AgNO3) is supplied by Jain Scientific Equipments Private Limited, which operates under the ScienceLab brand from Ambala, Haryana, sourcing reagents, glassware and science apparatus for schools, colleges and laboratories in India and international markets.

Browse all reagents, stains and apparatus in the Biology Lab category.

Frequently Asked Questions

How much Silver Nitrate (AgNO3) is in one pack?
One pack of Silver Nitrate (AgNO3) contains 20 g of analytical reagent grade salt with an MSDS. Because working solutions for chloride tests are dilute, a small pack goes a long way in a school or college lab.

Why does tap water turn cloudy with Silver Nitrate (AgNO3)?
Tap water usually contains chloride, which reacts with Silver Nitrate (AgNO3) to form white silver chloride. Use distilled water for making the solution and for rinsing glassware, so that only the sample can cause the precipitate.
