Nesslers Reagent (Product Code: SCL-903/194) is an alkaline colour reagent used to detect ammonia and ammonium ions in school, college and water-testing laboratories. Chemistry students rely on it to confirm the ammonium radical in salt analysis, and each 100 ml bottle is analytical reagent grade and comes with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India for teaching and testing laboratories.

Specifications

What Is Nessler's Reagent Used For?

In salt analysis, the ammonium radical is usually indicated first by warming the salt with sodium hydroxide and noticing the smell of ammonia; Nessler's reagent then gives the confirmatory result. Pass the evolved gas into the reagent, or add a few drops of reagent to the alkaline test solution, and a brown precipitate or deep yellow-brown colour confirms ammonium. In water studies, students add the reagent to samples from different sources and compare the depth of yellow colour against a clean distilled-water blank to see which samples carry more ammonia.

Nessler's reagent is a mercury-based alkaline reagent, so it is toxic and corrosive: dispense it with a dropper, wear gloves and eye protection, and collect used solutions for proper heavy-metal waste disposal instead of pouring them into the sink. The 100 ml bottle is sized for drop-wise use, which suits a salt analysis kit for school practicals where each student needs only a few drops per test.

Oxalic Acid (Product Code: SCL-911/198) is a dicarboxylic acid used to prepare primary standard solutions for titrations in school, college and quality-control laboratories. Chemistry teachers choose it because it weighs out accurately and reacts in a fixed ratio with potassium permanganate and sodium hydroxide; this analytical reagent grade material is supplied with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, and is a core item in any volumetric analysis kit in India.

Specifications

What Is Oxalic Acid Used For?

The best-known practical is the redox titration of potassium permanganate against a standard oxalic acid solution. Students weigh the acid on an analytical balance, make it up to the mark in a volumetric flask, pipette a portion into a conical flask, acidify it with dilute sulphuric acid and warm it, because the reaction is slow when cold. Permanganate is run in from the burette until a faint pink colour stays; no separate indicator is needed because permanganate itself shows the end point. The same standard solution is used in acid–base work to find the exact strength of a sodium hydroxide solution with phenolphthalein as indicator.

Weigh by difference, use freshly boiled and cooled distilled water for the alkali titration, and label each standard solution with its concentration and date. Oxalic acid is harmful if swallowed and irritates skin and eyes, so keep it well away from food areas and wash hands after weighing. Schools putting together a titration kit for school practicals generally keep oxalic acid as their primary standard because it is easy to handle.

Supplier

Oxalic Acid is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India. The company sources titration reagents such as this one so that a school or college can order its standards, indicators and glassware in a single enquiry, for delivery in India and international markets.

Petroleum Jelly White (Product Code: SCL-913/199) is a soft white semi-solid jelly used to seal, lubricate and protect in school and college laboratories, from bell-jar rims to glass stopcocks. Each 500 gm pack is paraben and phthalate-free, and the product listing also describes it as a skin-care jelly for dry skin and minor cuts. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab consumables supplier in India for institutional laboratories.

Specifications

What Is Petroleum Jelly Used For?

A thin smear of petroleum jelly around the ground rim of a bell jar or the flange of a desiccator lid creates an airtight seal, which is essential in experiments on plant respiration, photosynthesis and drying of samples. It is also used to lubricate glass stopcocks and to seal the joints of simple gas apparatus. In biology practicals, students coat the upper or lower surface of leaves with the jelly to block the stomata and compare water loss, and in rusting experiments an iron nail greased with petroleum jelly shows how a barrier layer keeps out air and moisture.

Apply only a thin, even film with a spatula or clean fingertip; excess jelly can creep into apparatus and contaminate samples. Wipe off old grease with a dry cloth before re-applying. Its skin-softening character makes it handy in the lab for chapped hands, although it is not a substitute for gloves when handling chemicals. A pack sits comfortably among the biology lab equipment in India that schools stock for plant physiology work.

Plaster of Paris (POP) (Product Code: SCL-919/202) is calcium sulphate hemihydrate, a fine white powder used to study setting reactions and to cast moulds and models in school science laboratories. Teachers use the 500 gm pack, listed as analytical reagent grade with an MSDS, for lessons on the properties of salts and for art-integrated casting projects. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside the science kits for students in India that schools order for practical work.

Specifications

What Is Plaster of Paris Used For?

When students study salts, they mix a spoonful of POP with water in a china dish and observe that the paste warms slightly and hardens as it takes up water and turns back into gypsum. The same property is used to make casts of leaves, shells and footprints for biology and earth-science displays, to prepare moulds for small models, and in older laboratory practice to seal gaps around apparatus joints. Teachers can pair the setting experiment with a discussion of how POP is made by heating gypsum and why it is stored away from moisture.

For a smooth paste, sprinkle the powder into the water rather than the other way round, stir without whipping in air, and pour promptly because the mix stiffens quickly. Clean bowls and spatulas before the plaster hardens, and never pour leftover slurry into a sink, where it can set in the drain. A 500 gm pack is a convenient quantity for class demonstrations and project work.

Supplier

Plaster of Paris (POP) comes from Jain Scientific Equipments Private Limited, which trades as ScienceLab in Ambala, Haryana, India. The company supplies practical materials such as this alongside laboratory apparatus, so teachers can order a casting activity's powder, dishes and spatulas together for delivery in India and international markets. Background on the company is on the company profile page.

Frequently Asked Questions

Who supplies Plaster of Paris (POP) SCL-919/202?
Plaster of Paris (POP) SCL-919/202 is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, Ambala, Haryana, India. The company sources the 500 gm analytical reagent grade pack, sends it with its MSDS and supplies schools and colleges in India and international markets.

How much Plaster of Paris does one pack contain?
One pack of Plaster of Paris (POP) contains 500 gm of fine powder, a convenient quantity for classroom setting demonstrations and several small casting projects such as leaf prints, shell casts or model moulds. Larger needs can be met with multiple packs.

Why does Plaster of Paris harden after mixing with water?
Plaster of Paris hardens because the calcium sulphate hemihydrate takes up water and re-forms gypsum crystals, which grow and interlock into a solid mass. The reaction releases a little heat, so students can feel the paste warm slightly as it sets.

What is the shelf life of Plaster of Paris (POP)?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep Plaster of Paris sealed in a dry place, because moisture from the air makes the powder lump and set poorly.

Is Plaster of Paris safe for students to handle?
With normal care, Plaster of Paris is suitable for supervised student use. Avoid breathing the dust, keep it out of eyes, and never cast plaster around hands or fingers because it warms as it sets. The MSDS supplied with each pack gives full guidance.

What should a school include in a Plaster of Paris enquiry?

Potassium Ferricyanide (Product Code: SCL-927/206) is potassium hexacyanoferrate(III), a reagent used to identify ferrous iron by its intense dark blue precipitate in inorganic qualitative analysis. Schools and colleges also use it for corrosion indicator gels and cyanotype demonstrations, and each 500 gm pack is analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, whose role as a laboratory chemicals supplier in India lets departments order reagents with their apparatus.

Specifications

What Is Potassium Ferricyanide Used For?

In salt analysis, a freshly prepared potassium ferricyanide solution is added to the original solution when iron is suspected. A dark blue precipitate confirms ferrous ions, while ferric ions give only a brown or greenish colour; the companion reagent potassium ferrocyanide is then used to confirm ferric iron with its own blue precipitate. Beyond qualitative analysis, the reagent is mixed into salt-agar or ferroxyl gels to show the blue patches where iron nails begin to corrode, and it is one of the two chemicals in the cyanotype or blueprint process used in photography and art-science projects.

Prepare the test solution in small amounts on the day of use, since solutions slowly decompose in light. Never mix the solid or its solution with concentrated acids or heat it strongly, because toxic cyanide fumes can be released; carry out tests in test tubes and dispose of residues as advised in the MSDS. For departments building a full set of school chemistry lab equipment in India, this reagent sits naturally beside the iron salts used in cation analysis.

Supplier

Potassium Ferricyanide is supplied by Jain Scientific Equipments Private Limited, known by its trading name ScienceLab and based in Ambala, Haryana, India. The company sources analytical reagents for cation analysis and dispatches them with the iron salts and glassware a practical needs, to institutions in India and international markets. For company background, see the company profile.

Potassium Hydroxide Pellets (Product Code: SCL-933/209) are analytical reagent grade pellets of the strong alkali potassium hydroxide, used to prepare alkaline solutions for titrations, saponification and organic chemistry practicals in college and school chemistry labs. They come in a 500 g pack supplied with an MSDS. They are supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India.

Specifications

What Are Potassium Hydroxide Pellets Used For?

Dissolved in water or ethanol, potassium hydroxide gives a strong base for acid-base titrations and for saponification, in which fats and oils are boiled with alcoholic KOH to form soap and glycerol — the basis of saponification-value determinations in college labs. Its high solubility also makes it a useful base in organic preparations and for absorbing carbon dioxide from gas streams.

The pellets absorb moisture and carbon dioxide from the air, so weigh them quickly and close the container at once; solutions for accurate work should be standardised against a primary standard rather than made up by weight alone. Dissolving the pellets releases considerable heat, so add them gradually to cold water in a heat-resistant vessel while wearing goggles and gloves.

Potassium Meta Bisulphite (Product Code: SCL-935/210), often shortened to KMS, is a white salt used as a preservative and as a laboratory source of sulphur dioxide in chemistry, home science and food technology labs. It releases sulphur dioxide when it meets acid, and each 250 gm pack is analytical reagent grade with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, together with the school chemistry lab equipment in India that the company provides.

Specifications

What Is Potassium Meta Bisulphite Used For?

In food science and home science practicals, students add a measured pinch of KMS to fruit juices, squashes or pulp and compare how long treated and untreated samples take to ferment or grow mould, which demonstrates chemical preservation in a way that is easy to observe. In chemistry, a little of the salt warmed with dilute hydrochloric acid generates sulphur dioxide, which students identify by its sharp smell and by its ability to decolourise acidified potassium permanganate. The same reducing action explains why KMS is used to sterilise fermentation equipment and to stop browning of cut fruit.

Carry out the gas-generation test in a fume cupboard or near an open window, as sulphur dioxide irritates the airways and can trouble people with asthma. Keep the pack sealed and dry; damp salt slowly loses sulphur dioxide and becomes weaker. Buying from a lab consumables supplier in India that also stocks sodium benzoate lets a class compare two common preservatives side by side.

Supplier

Potassium Meta Bisulphite is supplied by Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, India, to schools, colleges and food technology laboratories in India and international markets. For vendor registration, the supplying company is Jain Scientific Equipments Private Limited (CIN U29309HR2020PTC087597, GSTIN 06AAECJ8618A1ZT). Learn more on the company profile page.

Propane-2-ol (Product Code: SCL-939/212), better known as isopropyl alcohol or propan-2-ol, is the simplest secondary alcohol, used as a solvent and as a test compound in school, college and biotechnology laboratories. Each 250 ml bottle is analytical reagent grade and is supplied with an MSDS for alcohol-test practicals, lens cleaning and DNA precipitation. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

Specifications

What Is Propane-2-ol Used For?

Propan-2-ol is the standard example of a secondary alcohol in practicals that distinguish primary, secondary and tertiary alcohols. With the Lucas test it turns cloudy after a short delay, placed between methanol, which shows no quick change, and tertiary butyl alcohol, which clouds almost at once. It also gives a positive iodoform test, producing a yellow precipitate with iodine in alkali, and on oxidation it forms acetone, a useful link between the alcohol and ketone chapters. In biology and biotechnology labs, cold isopropyl alcohol is used to precipitate DNA in simple extraction experiments.

It evaporates quickly and leaves little residue, so a lint-free tissue moistened with it is handy for cleaning microscope lenses, pH electrodes and glass slides. The liquid and its vapour are highly flammable: keep the bottle capped, work away from burners, and use only small amounts on open benches. A 250 ml bottle is a practical size for a class set of alcohol tests within a well-planned set of chemistry lab equipment in India.

Supplier

Propane-2-ol is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades as ScienceLab.

Yes. Propane-2-ol, propan-2-ol, isopropanol and isopropyl alcohol are all names for the same secondary alcohol. The product code SCL-939/212 identifies this analytical reagent grade bottle, so quote it in your enquiry to avoid confusion with other alcohols.

What volume does a bottle of Propane-2-ol hold?
Each bottle of Propane-2-ol holds 250 ml, a practical size for a class set of Lucas and iodoform tests or for cleaning optics. Larger requirements are met with multiple bottles, so state the total volume you need when you request a quotation.

Can Propane-2-ol be used to clean microscope lenses?
Yes. Applied sparingly on lens tissue, Propane-2-ol removes oil and fingerprints from microscope lenses, pH electrodes and glass slides and evaporates with little residue. Check the microscope maker's advice first for lenses with special coatings.

What is the shelf life of Propane-2-ol?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep Propane-2-ol tightly capped in a cool, ventilated place away from heat and flames, because it is highly flammable.

What should an institutional quotation for Propane-2-ol include?
An institutional request for Propane-2-ol should list the product code SCL-939/212, the number of bottles, the delivery address and any tender reference. Send these through the contact page, and add the other alcohols for the comparison practical so they are quoted together.
