Ether (Product Code: SCL437/0125) is a volatile organic solvent, in teaching labs normally diethyl ether, used to dissolve fats and oils in lipid solubility tests during biology practicals. Supplied in a 500 ml pack of analytical reagent grade, it also appears in some genetics courses for briefly immobilising fruit flies, and it is dispatched with an MSDS because of its fire hazard. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier to schools and colleges.

Specifications

What Is Laboratory Ether Used For?

The most common school use is the solubility test for lipids. Students shake a little oil or fat with water in one tube and with ether in another; the fat stays as a separate layer in water but disappears into the ether. Placing a drop of the ether extract on paper and letting it evaporate leaves a translucent grease spot, confirming that the dissolved material is a lipid. Ether is also used to extract fats from crushed seeds and, in some genetics courses, to anaesthetise Drosophila for sorting, although many teachers now prefer other methods for that step.

Ether is extremely flammable and its vapour is heavier than air, so it can travel along the bench to a flame. Work with no spirit lamps or burners lit in the room, use it in a fume cupboard or near an open window, and dispense only the small volume each group needs. Once a bottle is opened, write the opening date on the label: ether can form hazardous peroxides with prolonged exposure to air and light, so opened stock should be used promptly and stored cool, dark and tightly sealed.

Ether is supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab brand in Ambala, Haryana. It provides laboratory reagents together with glassware and apparatus to schools, colleges, training institutes and laboratories in India and international markets.

Spirit (Product Code: SCL438/0126) is a laboratory alcohol used to fuel spirit lamps, clean slides and instruments, and prepare or keep specimens in school and college biology labs. Its large 2 litre pack of analytical reagent grade suits institutions that run several practical batches each week, and it is dispatched with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier for schools and colleges.

Specifications

What Is Laboratory Spirit Used For?

Most bottles of spirit in a school lab end up in spirit lamps, which give a clean, small flame for flaming inoculation loops and needles, warming a stained slide gently, or heating a test tube in a botany practical. Spirit is also the usual liquid for wiping grease and fingerprints off glass slides before mounting, cleaning dissection instruments after use, and swabbing work surfaces at the end of a microbiology session. In slide-making work, alcohol is used to dehydrate stained sections before mounting, and teachers often keep collected specimens in spirit for short-term study.

The word spirit can mean different alcohol-based products in different syllabi and regions, so tell us whether your manual specifies rectified, methylated or another type and we will confirm what this pack supplies. Treat it as a flammable liquid: refill lamps only after they have been put out and cooled, never overfill the reservoir, decant from the 2 litre pack into a smaller labelled bottle for bench use, and store the main container in a cool cupboard away from flames.

Supplier

Spirit is supplied by Jain Scientific Equipments Private Limited, located in Ambala, Haryana, which trades as ScienceLab. Alongside reagents like this one, the company supplies glassware, instruments and teaching apparatus for laboratories in India and international markets. Learn more on our company profile.

Sucrose (Product Code: SCL440/0128) is an analytical reagent grade cane sugar used as the standard non-reducing sugar, osmosis solute and yeast food in school and college biology practicals. The 500 g pack gives plant biology and biochemistry classes material for many class sets of sugar-test and osmosis solutions, and each pack carries an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as one of its lab chemicals for teaching laboratories.

Specifications

What Is Sucrose Used For?

In the carbohydrate practical, a sucrose solution heated with Benedict's or Fehling's reagent stays blue, because sucrose has no free reducing group. Boiling a second portion with dilute acid splits it into glucose and fructose; after neutralising, the same test turns brick red. Running both tubes side by side, with a glucose tube as a positive control, is one of the clearest ways to teach the difference between reducing and non-reducing sugars.

Sucrose is equally useful in plant physiology. Solutions of increasing strength are used to show osmosis in potato strips or a thistle-funnel osmometer, and to demonstrate plasmolysis in onion or Rhoeo peel under the microscope, making it a staple next to plant biology lab equipment such as osmosis apparatus. Weigh it on a balance for accurate solutions, use distilled water, and make fresh solutions for each session, because sugar solutions left standing can grow moulds and bacteria.

Supplier

Sucrose is supplied by Jain Scientific Equipments Private Limited, trading as ScienceLab, which is based in Ambala, Haryana and sources reagents, glassware and laboratory apparatus for educational and research users. Institutional buyers completing vendor forms can note the company's GST registration, GSTIN 06AAECJ8618A1ZT, and its Importer-Exporter Code AAECJ8618A from the DGFT, under which export orders are shipped.

These products are used with sucrose in carbohydrate and osmosis practicals:

• Benedicts Reagent (Test Of Glucose) — shows that sucrose does not reduce copper until it is hydrolysed
• Fehling's Sol A (Test Of Sucrose) — the alternative copper test many manuals use for the same comparison
• Glucose — the reducing-sugar positive control run beside the sucrose tube
• Hydrochloric Acid (Conc) — diluted for the acid hydrolysis step
• Osmotic Pressure Apparatus — uses sucrose solution to demonstrate osmosis through a membrane

Explore more in the Biology Lab category.

Frequently Asked Questions

Why use reagent-grade Sucrose instead of table sugar?
This Sucrose is analytical reagent grade, so test results are not affected by the colourings, anti-caking agents or impurities that kitchen sugar may carry. That matters most when a Benedict's or Fehling's test depends on a clear negative result.

How much Sucrose does one pack contain?
Each pack of Sucrose contains 500 g of analytical reagent grade sugar and comes with an MSDS, enough for many class sets of osmosis, plasmolysis and sugar-test solutions in a school or college laboratory.

Will Sucrose give a positive Benedict's test?
Not directly. Sucrose gives a positive Benedict's result only after acid hydrolysis and neutralisation, which split it into glucose and fructose; this is exactly why it is used to teach the idea of a non-reducing sugar.

What is the shelf life of Sucrose?
The shelf life of Sucrose 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 keep the pack tightly closed and dry, because sucrose absorbs moisture and forms lumps.

Who supplies Sucrose?
Sucrose is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges and distributors, together with Benedict's and Fehling's reagents, glucose and osmosis apparatus for complete carbohydrate and plant physiology practicals.

Is batch documentation available for Sucrose beyond the MSDS?
Sucrose is supplied with an MSDS. For any further batch documentation, please discuss your needs with us through the contact page before ordering, and we will tell you what can be provided for the current batch.

Can Sucrose be ordered in bulk or for export?
Yes. Sucrose is supplied to schools, colleges and distributors in India and international markets; share the number of 500 g packs and the destination, and a quotation will be prepared with suitable packing.

Sulphosalicylic Acid (Product Code: SCL441/0129) is an analytical reagent grade acid used to precipitate proteins, most often to check urine for protein (albumin) in physiology and paramedical practicals. Supplied as a 500 g pack with an MSDS, it lets teaching and clinical training labs make their own working solution, which turns a clear protein-containing sample cloudy. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, which also supplies school laboratory equipment and reagents.

Specifications

What Is Sulphosalicylic Acid Used For?

Lab staff dissolve the acid in distilled water to make the working solution recommended in their practical manual. A clear urine sample is placed in a test tube, the solution is added, and the tube is held against a dark background: a white turbidity or precipitate indicates protein, and the degree of cloudiness gives a rough idea of how much is present. Because the reagent precipitates a broad range of proteins, it is a helpful cross-check alongside dipstick results and the biuret test in physiology and paramedical courses.

Cloudy urine should be filtered or centrifuged before testing, otherwise suspended material can be mistaken for a positive result; always test a portion of the untreated sample as a comparison. Wear eye protection when weighing the solid and preparing solutions, and label the working bottle with the date it was made. Teachers building a complete urine-analysis bench usually order this acid together with the sugar and bile-pigment reagents so each station has a full set.

Supplier

Sulphosalicylic Acid is supplied by Jain Scientific Equipments Private Limited, the company behind the ScienceLab brand in Ambala, Haryana, which sources laboratory reagents, glassware and teaching apparatus. Its customers include schools, colleges, hospital training labs and distributors in India and international markets. See our company profile for details.

Frequently Asked Questions

Is Sulphosalicylic Acid the same as "sulphosalicyclic acid"?
Yes. "Sulphosalicyclic acid" is a common misspelling of Sulphosalicylic Acid, the reagent used for protein precipitation; purchase lists or tenders that use either spelling refer to this same 500 g analytical reagent pack.

In what form and quantity is Sulphosalicylic Acid supplied?
Sulphosalicylic Acid is supplied in a 500 g pack of analytical reagent grade, with an MSDS. Labs prepare the working solution themselves, in the concentration their practical manual or clinical protocol directs.

What strength of Sulphosalicylic Acid solution should we prepare?
Follow the concentration of Sulphosalicylic Acid solution given in your practical manual or clinical protocol. If you are unsure, ask us through the contact page and we will point you to the right reference rather than guess a figure.

What does a positive Sulphosalicylic Acid test look like?
In the Sulphosalicylic Acid test, a white turbidity or precipitate in clear urine indicates protein, and the degree of cloudiness gives a rough idea of the amount. Filter or centrifuge cloudy urine first and compare with an untreated portion.

What is the shelf life of Sulphosalicylic Acid?
The shelf life of Sulphosalicylic Acid 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 store the container closed, dry and away from strong bases and oxidisers.

Who supplies Sulphosalicylic Acid?
Sulphosalicylic Acid is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India, to schools, colleges, hospital training labs and distributors in India and international markets, often with the other urine-analysis reagents.

Sulphuric Acid (H2SO4) Cono (Product Code: SCL443/0130) is a concentrated mineral acid used to drive colour tests for carbohydrates and to prepare dilute acid for hydrolysis steps in school and college biology laboratories. Teachers and lab assistants order it as a 500 ml pack of analytical reagent grade, shipped with an MSDS because the acid is highly corrosive. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India for teaching and research users.

Specifications

What Is Concentrated Sulphuric Acid Used For?

In Molisch's test, a carbohydrate solution is mixed with Molisch reagent and the concentrated acid is run slowly down the side of the tilted tube so that it forms a dense bottom layer; a violet ring at the junction shows that a carbohydrate is present. The same acid is used in the Salkowski test for cholesterol and, once diluted, to hydrolyse starch or sucrose before a reducing-sugar test. Because the result depends on a clean layer, students should add the acid with a pipette fitted with a filler rather than pouring from the bottle.

Safety comes first with this reagent. Always add acid to water, slowly and with stirring, never water to acid, because dilution releases a lot of heat. Wear splash goggles and acid-resistant gloves, keep running water close by for rinsing any splash, and store the bottle upright in an acid cabinet or tray away from bases, metals and organic materials. Dispensing small volumes into labelled bench bottles keeps the stock bottle closed and clean, a habit that suits any school biology lab setup in India.

Supplier

Jain Scientific Equipments Private Limited trades as ScienceLab from Ambala, Haryana, and supplies this acid as part of its reagent range for teaching and research laboratories. The company sources and dispatches chemicals, glassware and apparatus to schools, colleges, universities and institutional buyers in India and international markets.

Frequently Asked Questions

Is Sulphuric Acid (H2SO4) Cono concentrated or dilute acid?
Sulphuric Acid (H2SO4) Cono is concentrated sulphuric acid, supplied as a 500 ml pack of analytical reagent grade with an MSDS. Dilute solutions are not sold under this code; labs prepare them from the concentrated acid as their practical manual requires, always adding acid to water.

How do we prepare dilute sulphuric acid safely from this pack?
To dilute Sulphuric Acid (H2SO4) Cono safely, measure the water first into a heat-resistant beaker, then add the concentrated acid slowly while stirring and let the solution cool before bottling. Never reverse the order, and wear goggles and gloves throughout, because the mixing releases strong heat.

What is the shelf life of Sulphuric Acid (H2SO4) Cono?
Shelf life depends on the chemical, its grade and storage conditions, so we do not quote a blanket period for Sulphuric Acid (H2SO4) Cono. Ask us for the expiry date of the batch you are quoted, and keep the cap tight so the acid does not absorb moisture from the air.

What should we do if the acid splashes on skin?
If Sulphuric Acid (H2SO4) Cono splashes on skin, rinse the area immediately with plenty of running water and follow the first-aid steps in the MSDS supplied with the pack. Seek medical help for any significant exposure and for any splash that reaches the eyes.

Universal Indicator Sol (Product Code: SCL444/0131) is a universal indicator solution used to estimate by colour how acidic or alkaline a sample is in school biology and chemistry practicals. Teachers choose it over litmus because it passes through a whole spectrum of colours rather than two, and it comes as a 500 ml pack of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, for buyers sourcing universal indicator solution in India.

Specifications

What Is Universal Indicator Solution Used For?

In biology practicals the indicator turns up in more places than students expect. Soil shaken with distilled water and allowed to settle is tested for acidity before a plant-growth project, and breathing gently through a straw into water containing the indicator shows the colour shifting towards acid as carbon dioxide dissolves. In digestion experiments it tracks the fall in pH as lipase breaks milk fat down into fatty acids, and environmental studies use it to survey pond, tap and rain water.

Add only a few drops to a colourless or lightly coloured sample, mix, and compare the colour straight away with a universal indicator colour chart under white light. Strongly coloured samples such as plant extracts can mask the result, so pH paper or a pH meter is the better choice there. Teachers who need a number rather than a colour band keep a meter alongside, and the solution fits naturally into an acid base indicator kit for the school laboratory.

Supplier

Universal Indicator Sol is supplied by ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, Haryana. The company supplies reagents, glassware and science lab apparatus to schools, colleges and research users in India and international markets. Our company profile explains more about who we are.

Tools that complement a universal indicator in pH work:

• Ph Paper — a quick strip test for samples too coloured for the liquid indicator.
• Digital Ph Meter (Table Top) — gives a numerical reading when a colour estimate is not precise enough.
• Litmus Sol Red/Blue — the simpler acid/alkali indicator for introductory lessons.
• Phenol Red (Test Of Urea In Urine) — a single indicator for the urease test and carbon dioxide experiments.
• Dropper — adds the indicator drop by drop so the colour is not diluted out.

Visit the Biology Lab category for more practical supplies.

Frequently Asked Questions

How much indicator is in one pack of Universal Indicator Sol?
Each pack of Universal Indicator Sol holds 500 ml of analytical reagent grade solution and is supplied with an MSDS. Since only a few drops are needed for each test, a single pack can serve many practical classes, depending on how the stock is dispensed.

Is a colour chart included with Universal Indicator Sol?
The listing for Universal Indicator Sol does not state that a colour chart is included, so please confirm this with us through the contact page before ordering. We will not promise an accessory that we cannot confirm for your consignment.

How is Universal Indicator Sol different from litmus?
Litmus only shows whether a sample is acidic or alkaline. Universal Indicator Sol changes through a sequence of colours across the pH scale, so students can also estimate how strongly acidic or alkaline the sample is, which makes it more useful for soil, water and enzyme experiments.

What is the shelf life of Universal Indicator Sol?
Shelf life depends on the chemical, its grade and storage conditions, so no fixed period is quoted for Universal Indicator Sol. Ask us for the expiry date of the batch you are quoted, keep the bottle closed and out of sunlight, and check the stock against a known buffer if its colour changes.

Is Universal Indicator Sol flammable?
Some universal indicator solutions contain alcohol, so treat Universal Indicator Sol as potentially flammable until you have read the MSDS supplied with the pack. The MSDS gives the exact hazard information; as a precaution, keep the bottle away from flames and heat sources.

Who supplies Universal Indicator Sol?
Universal Indicator Sol is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), based in Ambala, Haryana, India. The company provides the indicator alongside pH paper, pH meters and other reagents, and it quotes schools, colleges, dealers and export buyers in India and international markets.

Urease Powder (Test Of Urea Urine) (Product Code: SCL447/0132) is a powdered urease enzyme used to detect urea in urine samples in biology practicals. Students add it with an indicator such as phenol red, because urease breaks urea into ammonia and carbon dioxide and the rising alkalinity shows as a colour change; the pack is listed at 125 ml, analytical reagent grade, with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, as the core of an enzyme activity kit for biology classes.

Specifications

What Is Urease Powder Used For?

A typical school or college set-up uses three tubes: urine with a few drops of phenol red, water with indicator as a blank, and urine with indicator plus urease that has been boiled first. When a pinch of active urease is added to the first tube, the colour moves from yellow-orange towards pink-red as ammonia forms, while the blank and the boiled-enzyme tube stay unchanged. In one short practical, students see a positive test for urea, the specificity of an enzyme for its substrate and the effect of heat denaturation.

Because the test depends on enzyme activity, keep the container tightly closed in a cool, dry place and try the powder on a prepared urea solution before the class, so a weak batch or damp powder is noticed in advance. Warm rather than hot conditions speed the reaction, while boiling destroys it. Combined with phenol red and urea, this powder forms a low-cost enzyme experiment kit for school biology.

Frequently Asked Questions

Why is Urease Powder (Test Of Urea Urine) listed with a capacity of 125 ml?
The listing gives the pack capacity of Urease Powder (Test Of Urea Urine) as 125 ml, which most likely describes the container rather than the weight of powder inside. Ask us through the contact page for the exact fill quantity before you order.

Do I need phenol red as well as the urease powder?
Yes. Urease Powder (Test Of Urea Urine) produces no visible colour by itself; it releases ammonia from urea, and an indicator such as phenol red shows the resulting rise in pH. Order the indicator alongside the enzyme if your lab does not already stock one.

Why did the urease test tube not change colour?
When a test with Urease Powder (Test Of Urea Urine) shows no change, check that the enzyme was not heated or stored damp, that indicator was added, and that a prepared urea control turns colour. A failed control points to the enzyme or indicator rather than the sample.

What is the shelf life of Urease Powder (Test Of Urea Urine)?
Shelf life depends on the chemical, its grade and storage conditions, so no blanket period is given for Urease Powder (Test Of Urea Urine). Ask us for the expiry date of the batch you are quoted, store it closed, cool and dry, and confirm enzyme activity with a urea control each term.

Who supplies Urease Powder (Test Of Urea Urine)?
Urease Powder (Test Of Urea Urine) is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab) of Ambala, Haryana, India. The company can quote the enzyme together with phenol red, urea and test tubes, so a complete urea-in-urine practical can be ordered from one source.

What should an institutional enquiry for this urease powder include?
An enquiry for Urease Powder (Test Of Urea Urine) should give product code SCL447/0132, the number of packs, any companion reagents, the delivery address and billing details. We quote for schools, colleges and distributors in India and international markets.

Phenol Red (Test Of Urea In Urine) (Product Code: SCL449/0133) is a pH indicator used to reveal the ammonia released when urease acts on urea during urine tests in biology laboratories. It is yellow in acidic conditions and turns red, then pink-magenta, as a mixture becomes alkaline, and schools receive it as a 500 ml pack of analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier for schools and colleges.

Specifications

What Is Phenol Red Indicator Used For?

For the urea test, a few drops of phenol red are added to the urine sample, which usually shows a yellow to orange tint. After urease is added, the enzyme releases ammonia from any urea present and the colour deepens to red and then pink as the mixture becomes alkaline. Setting up an indicator-only blank and a known urea standard beside each sample helps students judge the change fairly and stops a naturally alkaline sample from being misread.

The same indicator is useful beyond the urea test. Because dissolved carbon dioxide makes water more acidic, phenol red turns from red towards yellow when students breathe into it, and it can show carbon dioxide uptake by aquatic plants in light as the water drifts back towards red. That versatility makes it a practical member of any acid base indicator kit on the biology bench; dispense it with a dropper and keep the stock bottle closed and free of sample contamination.

Frequently Asked Questions

What volume of Phenol Red (Test Of Urea In Urine) is supplied?
Each pack of Phenol Red (Test Of Urea In Urine) contains 500 ml of analytical reagent grade indicator and is supplied with an MSDS. Only a few drops are needed per tube, so one pack covers a large number of student tests.

Can Phenol Red (Test Of Urea In Urine) detect urea on its own?
No. Phenol Red (Test Of Urea In Urine) only shows a change in pH. The urease enzyme is needed to convert urea into ammonia, and it is that ammonia which raises the pH and turns the indicator from yellow-orange towards red and pink.

Why did the sample turn pink before urease was added?
Some urine samples are already alkaline, especially after standing for a long time, so Phenol Red (Test Of Urea In Urine) may turn pink before any enzyme is added. Use fresh samples and always compare each tube with an indicator-only blank.

What is the shelf life of Phenol Red (Test Of Urea In Urine)?
