What Is Copper Sulphate Used For?
Laboratories that prefer to make up their own test reagents use copper sulphate as the copper source: a dilute solution added to an alkaline protein sample gives the biuret test, and copper sulphate solution forms the "A" half of Fehling's solution. In chemistry-linked lessons, gently heating the blue hydrated salt in a china dish drives off its water of crystallisation and leaves a white powder that turns blue again when water is added, showing both dehydration and a chemical test for water.
Slow evaporation of a saturated solution produces well-formed blue crystals for crystallisation projects, which is why the salt is a stock item wherever chemistry lab equipment in India is bought alongside biology reagents. Copper sulphate is harmful if swallowed and irritating to eyes and skin, so use gloves and goggles, weigh it on a clean balance and collect concentrated waste instead of pouring it away.

Frequently Asked Questions
Can I prepare biuret or Fehling's reagent from Copper Sulphate?
Yes, Copper Sulphate supplies the copper ions for both biuret reagent and Fehling's Solution A. The other components, such as the alkali, are needed separately, and ready-made versions of these reagents are also listed in our Biology Lab range.
What quantity does a pack of Copper Sulphate contain?
A pack of Copper Sulphate contains 500 gm of analytical reagent grade salt and comes with its MSDS. The quantity suits departments that prepare their own test reagents as well as run crystallisation and dehydration demonstrations.
Why does Copper Sulphate turn white when heated?
Copper Sulphate turns white when heated because heating drives off the water of crystallisation from the blue hydrated salt, leaving white anhydrous copper sulphate. Adding a few drops of water restores the blue colour, which also works as a simple test for water.
What safety precautions apply to Copper Sulphate?
Copper Sulphate is harmful if swallowed and irritates eyes and skin, so wear gloves and goggles when weighing or dissolving it. Collect copper-containing waste rather than pouring it down the drain, as copper salts are toxic to aquatic life; the MSDS gives full guidance.
How long does Copper Sulphate keep?
The shelf life of Copper Sulphate depends on the chemical, its grade and storage conditions, so ask us for the expiry date of the batch you are quoted. Keep the container closed in a cool, dry place between practicals.

| Product code | SCL380/096 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Diastase Used For?
The standard practical mixes a starch solution with a diastase solution and removes drops at regular intervals onto iodine solution. At first the drops turn blue-black; as the enzyme digests the starch the colour weakens to brown and finally stays yellow-brown, showing that no starch remains. Testing the final mixture with Benedict's reagent then confirms that reducing sugar has been produced.
Repeating the run in tubes held at different temperatures or pH values turns it into an investigation of the factors affecting enzyme activity, a straightforward enzyme experiment kit school and first-year college classes can set up. Prepare the enzyme solution fresh on the day, never boil it unless you want a denatured control tube, and avoid breathing the powder, as enzyme dusts can cause sensitisation.
Supplier
Diastase is offered under ScienceLab, the trading name of Jain Scientific Equipments Private Limited of Ambala, Haryana, India. The company supplies enzymes and reagents together with the glassware and indicators needed to use them, and can check your protocol with you before you order. Read more in our company profile.

Frequently Asked Questions
What does Diastase (DNA Separation) do?
Diastase (DNA Separation) is an amylase: it hydrolyses starch into smaller sugars such as maltose. That is why starch gradually disappears from a mixture containing it, which students can follow with iodine solution during the practical.
How can students tell Diastase (DNA Separation) is working?
Students can tell Diastase (DNA Separation) is working when samples tested with iodine change from blue-black towards yellow-brown as starch is used up. A positive Benedict's test on the final mixture then confirms that reducing sugar has been produced.
Is Diastase (DNA Separation) suitable for DNA separation work?
Diastase (DNA Separation) is catalogued with the enzymes for DNA separation practicals, but diastase itself acts on starch. Please contact us with your protocol so we can confirm it suits your experiment before you place an order.

What Is Distilled Water Used For?
Almost every wet practical starts with distilled water: dissolving solid reagents such as salts, sugars and enzymes; diluting stains before staining onion peel or cheek cells; mounting specimens on slides; and giving glassware a final rinse so that no tap-water residue interferes with the next test. It also serves as the control liquid in many experiments, for example as the hypotonic medium in potato-strip or raisin practicals, where it forms part of an osmosis experiment kit school classes use alongside sugar or salt solutions.
To keep it clean, pour what you need into a beaker or wash bottle rather than dipping pipettes into the container, never return unused water to the stock, and keep the cap closed so the water does not absorb carbon dioxide and dust from the air. Rinse pH-meter electrodes with it between readings to avoid carry-over from one sample to the next.
Supplier
ScienceLab is the trading name of Jain Scientific Equipments Private Limited, based in Ambala, Haryana, India, which supplies consumables such as distilled water together with reagents and glassware to teaching laboratories.

| Product code | SCL382/098 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Ethanol Used For?
In the test for starch in a leaf, the leaf is first softened in boiling water, then placed in a tube of ethanol standing in the hot water bath until the green pigment dissolves out; after rinsing, iodine solution shows which parts of the leaf made starch. In DNA isolation, ice-cold ethanol poured gently onto the extract makes DNA come out of solution as white threads. For permanent slides, ethanol diluted with distilled water into a graded series gradually removes water from stained sections, pairing naturally with the stains of a staining kit for the biology lab in India.
Ethanol is highly flammable: never heat it directly over a flame, switch off burners before opening the bottle, and warm it only in a water bath heated beforehand. Keep the bottle tightly capped, away from heat and sunlight, preferably in a flammables cabinet, and follow the supplied MSDS for spills.
Supplier
This reagent is supplied under ScienceLab, the brand of Jain Scientific Equipments Private Limited, whose base is in Ambala, Haryana, India. The company serves educational and research laboratories with reagents, stains and apparatus, and confirms how flammable liquids will be packed for each delivery.

Explore more reagents in our Biology Lab range.
Frequently Asked Questions
Why is a leaf placed in Ethanol before the iodine test?
A leaf is placed in Ethanol before the iodine test because chlorophyll dissolves in it. Removing the green colour lets the blue-black starch-iodine reaction show clearly, so students can see exactly which parts of the leaf made starch.
Is it safe to heat Ethanol in class?
Ethanol should only be heated indirectly in class. It is highly flammable, so warm it in a tube standing in hot water that was heated beforehand, with all burners and flames switched off nearby, and follow the MSDS for spills.
What strength of Ethanol is supplied?
The Ethanol listing gives the grade as analytical reagent but does not state a percentage strength. If your protocol needs a particular concentration, for example for DNA precipitation, contact us to confirm before you order.
How much does a bottle of Ethanol contain?
A bottle of Ethanol contains 500 ml of analytical reagent grade alcohol and is supplied with its MSDS. For a graded dehydration series, the contents can be diluted with distilled water into several working strengths.
How long does Ethanol keep?
The shelf life of Ethanol depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Store the bottle tightly capped in a cool place away from ignition sources, ideally in a flammables cabinet.
Who supplies Ethanol?
Ethanol is supplied by Jain Scientific Equipments Pvt Ltd, which trades under the ScienceLab name from Ambala, Haryana, India. Schools, colleges and distributors in India and international markets can order it together with stains, iodine solution and glassware in a single quotation.
What should a quotation request for Ethanol include?

Fehling's Sol A (Test Of Sucrose)
Fehling's Sol A (Test Of Sucrose) (Product Code: SCL383/099) is the copper-containing half of Fehling's reagent, used with Fehling's Solution B to detect reducing sugars and, after acid hydrolysis, sucrose in school and college food-test practicals. It comes as an analytical reagent in a 500 ml pack with its MSDS, one half of the Fehling solution kit India's biology labs usually order as a pair. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

| Partner solution | Fehling's Solution B (listed separately) |
| Product code | SCL383/099 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Fehling's Solution A Used For?
Equal volumes of Solution A and Solution B are mixed in a test tube to give a deep blue working reagent, the sample is added and the tube is heated in a boiling water bath. A reducing sugar such as glucose converts the blue copper complex into a brick-red precipitate of copper(I) oxide. Sucrose, however, is a non-reducing sugar and leaves the mixture blue.
To test for sucrose, students first boil the sample with dilute hydrochloric acid to split it into glucose and fructose, neutralise the acid, and then repeat the Fehling's test; a red precipitate that appears only after hydrolysis points to sucrose. Running untreated and hydrolysed samples side by side, with glucose as a positive control, makes the comparison clear. Solution A contains copper salts, so wear goggles and gloves and collect waste rather than washing it away.
Supplier
ScienceLab is the trading name used by Jain Scientific Equipments Private Limited, based in Ambala, Haryana, India. The company supplies test reagents such as this solution alongside the glassware and heating apparatus used with them, and quotes both halves of Fehling's reagent together on request. Our company profile has more information.
Related Biology Lab Products
What you need alongside Solution A for a complete sugar test:
- Fehling's SOL B (TEST OF Sucrose) — the essential partner solution, mixed with A just before use
- Sucrose — the non-reducing sugar for the hydrolysis comparison
- Hydrochloric Acid (Conc) — diluted, it hydrolyses sucrose before testing
- Glucose — the positive-control reducing sugar
- Test Tubes (With Rim) — for heating reagent and samples in a water bath
More reagents are listed in our Biology Lab category.
Frequently Asked Questions
Can Fehling's Sol A (Test Of Sucrose) be used on its own?
No, Fehling's Sol A (Test Of Sucrose) must be mixed with Fehling's Solution B immediately before use. Neither solution works as a sugar test alone; the blue working reagent forms only when the copper solution meets the alkaline tartrate solution.
How does Fehling's Sol A (Test Of Sucrose) detect sucrose if sucrose is non-reducing?
Fehling's Sol A (Test Of Sucrose) detects sucrose by comparison: an untreated sucrose sample stays blue, while the same sample boiled with dilute acid and neutralised gives a red precipitate, because hydrolysis releases the reducing sugars glucose and fructose.
Why are the two halves of Fehling's reagent kept separate?
The two halves are kept separate because mixed Fehling's reagent does not keep well. Fehling's Sol A (Test Of Sucrose) and Solution B are therefore stored in their own bottles and combined fresh, in equal volumes, for each practical session.
How much solution does a pack of Fehling's Sol A (Test Of Sucrose) contain?
A pack of Fehling's Sol A (Test Of Sucrose) contains 500 ml of analytical reagent grade solution with its MSDS. Order the same volume of Solution B, since the two halves are mixed in equal parts for every test.
How long does Fehling's Sol A (Test Of Sucrose) keep?
The shelf life of Fehling's Sol A (Test Of Sucrose) depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep the bottle capped and store it as the MSDS advises.
Who supplies Fehling's Sol A (Test Of Sucrose)?
Fehling's Sol A (Test Of Sucrose) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India. Schools, colleges and distributors in India and international markets can order it with Solution B, sugars and test tubes in one quotation.

| Product code | SCL384/0100 |
| Supplied by | Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India |
What Is Fehling's Solution B Used For?
Fehling's Solution B is conventionally an alkaline solution of potassium sodium tartrate (Rochelle salt). On its own it is colourless and does nothing visible; its job begins when it meets Solution A. The tartrate binds the copper ions into a soluble deep-blue complex, and the alkali creates the conditions in which a reducing sugar can reduce that copper to red copper(I) oxide on heating. Students measure out matching volumes of A and B, mix them fresh, add the sample and heat.
Because Solution B is strongly alkaline, it is the more hazardous of the pair to handle: wear goggles and gloves, and rinse any splash with plenty of water. Keep the bottle tightly closed so the alkali does not absorb carbon dioxide, and prefer a plastic or rubber closure, since alkaline solutions can make ground-glass stoppers seize. It belongs on the reagent shelf of school chemistry lab equipment in India used for food and sugar testing.

Frequently Asked Questions
What does Fehling's SOL B (TEST OF Sucrose) do in the test?
Fehling's SOL B (TEST OF Sucrose) supplies the alkali and the tartrate. The tartrate keeps copper from Solution A dissolved as a deep-blue complex, and the alkaline conditions allow reducing sugars to reduce that copper to a red precipitate when heated.
Is Fehling's SOL B (TEST OF Sucrose) hazardous?
Yes, Fehling's SOL B (TEST OF Sucrose) is strongly alkaline and can damage skin and eyes, making it the more hazardous half of the pair. Use goggles and gloves, rinse splashes with plenty of water and follow the MSDS supplied with the pack.
How is Fehling's SOL B (TEST OF Sucrose) different from Benedict's reagent?
Fehling's SOL B (TEST OF Sucrose) is one of two separately stored solutions, whereas Benedict's reagent is a single, milder solution. Both detect reducing sugars, but Fehling's needs Solutions A and B mixed fresh in equal volumes for each test.
Which sugars give a positive result with Fehling's SOL B (TEST OF Sucrose)?
Mixed with Solution A, Fehling's SOL B (TEST OF Sucrose) gives a positive result with reducing sugars such as glucose, fructose, maltose and lactose. Sucrose reacts only after it has been hydrolysed with dilute acid and the acid neutralised.
How long does Fehling's SOL B (TEST OF Sucrose) keep?
The shelf life of Fehling's SOL B (TEST OF Sucrose) depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep it tightly closed so the alkali does not absorb carbon dioxide.

What Is Fructose Used For?
In the classic food-test practical, a fructose solution made up in distilled water is warmed with Benedict's or Fehling's solutions. Because fructose is a reducing sugar, a coloured precipitate forms, confirming that the reagents and heating step are working before students move on to fruit juice, honey or other samples. Fructose is also the usual positive sample for Seliwanoff's test, where ketoses develop a red colour faster than aldoses such as glucose, making it a useful teaching pair with glucose.
For day-to-day handling in school biology lab equipment setups in India, take out small portions with a clean, dry spatula and close the container straight away, as sugars readily absorb moisture and cake. Prepare sugar solutions fresh for each session and label them clearly, since stored sugar solutions can support mould or bacterial growth that spoils results.

The shelf life of Fructose depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep the container tightly closed in a cool, dry place so the sugar does not absorb moisture and cake.
Is a certificate of analysis provided with Fructose?
The MSDS is supplied with Fructose as standard. Availability of a certificate of analysis or other batch documentation should be discussed with us through the contact page before you place the order.
Who supplies Fructose?
Fructose is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, from Ambala, Haryana, India. The company sends it to schools, colleges and distributors in India and international markets, and packing and shipping terms for chemicals are confirmed order by order.
What should an institutional quotation request for Fructose include?

What Is Glucose Used For?
Teachers prepare a small set of glucose solutions of increasing strength and heat each with Benedict solution; in school labs across India this is the standard way to show the green, yellow, orange and brick-red colour series that makes Benedict's test semi-quantitative. Running glucose next to a non-reducing sugar such as sucrose also shows students why some sugars need to be hydrolysed before they give a positive result.
Beyond food tests, glucose is the usual substrate in yeast fermentation and respiration demonstrations and is used to make solutions for osmosis experiments across a semi-permeable membrane. Weigh it on a clean balance pan or weighing paper, dissolve it in distilled water, and discard leftover solution at the end of the session rather than storing it, since sugar solutions readily grow mould.

Frequently Asked Questions
Why is Glucose used as the control in Benedict's test?
Glucose is used as the control in Benedict's test because it is a reducing sugar that reliably gives a positive result. It confirms that the reagent and heating step are working before students judge the colour changes in unknown samples.
What pack size and grade of Glucose is offered?
Glucose is offered in a 500 gm pack of analytical reagent grade, supplied with its MSDS. Only a little sugar is dissolved for each set of food tests, so a single pack serves many practical sessions.
Is this Glucose the same as glucose sold for food or drinks?
No, this Glucose is a laboratory reagent intended for practical work, not a food product. It should not be eaten or used in food preparation, and it should be stored with other laboratory chemicals rather than in a kitchen or canteen.
Can Glucose be used for yeast fermentation experiments?
Yes, Glucose is the common sugar source for demonstrating fermentation and respiration by yeast, where the carbon dioxide released can be tested with lime water. The yeast and apparatus are ordered separately from this 500 gm pack.
How long does Glucose keep?
The shelf life of Glucose depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Store the pack sealed and dry, as the MSDS advises, and make solutions fresh for each session.
Who supplies Glucose?
Glucose is supplied by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab from Ambala, Haryana, India. Schools, colleges and distributors in India and international markets can order it with Benedict's reagent, other sugars and heating apparatus in one enquiry.
Can I order Glucose together with other food-test reagents?
Yes, Glucose can be ordered together with other food-test reagents. List all reagents and quantities in one enquiry, quoting code SCL386/0102 for this item, and we will reply with a combined quotation.
