Carbon Tetrachloride (Product Code: SCL-805/147) is a dense, non-polar chlorinated solvent used as the organic layer that reveals bromide and iodide during inorganic salt analysis in senior secondary and college laboratories. Teachers who assemble a school salt analysis kit often include a small bottle of it, and it also dissolves oils, greases and free halogens; it is packed as a 500 ml analytical reagent with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

Specifications

What Is Carbon Tetrachloride Used For?

During the confirmatory test for halide anions, a little of the salt solution is shaken in a test tube with carbon tetrachloride and chlorine water. Because the solvent does not mix with water and sinks to the bottom, the colour of the released halogen collects in that lower layer: orange to brown points to bromide, violet points to iodide. The same idea demonstrates the displacement order of the halogens.

Carbon tetrachloride is toxic when inhaled or absorbed through the skin, so dispense it in a fume cupboard, wear gloves and eye protection, and keep the volumes used per test very small. Collect used solvent in a labelled waste container rather than pouring it down the sink. It is also an ozone-depleting substance whose sale and use are regulated in many countries, so check the rules that apply to your laboratory.

Ceric Ammonium Nitrate (Product Code: SCL-807/148) is a solid cerium(IV) salt and strong oxidising agent used for the ceric ammonium nitrate test for alcohols and for redox work in school, college and research chemistry laboratories. Organic chemistry classes value it because only a pinch is needed per test, and it is packed as a 100 gm analytical reagent with an MSDS. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier for teaching laboratories.

Specifications

What Is Ceric Ammonium Nitrate Used For?

For the functional-group test, a small amount of the salt is dissolved in dilute nitric acid to give a yellow-orange reagent. A few drops of an unknown liquid are added: a change to red indicates an alcohol, whereas phenols tend to give a dark brown or greenish precipitate instead. Because only a pinch is needed per class set, a 100 gm pack goes a long way in a teaching laboratory. In higher-level work the same compound is used as a one-electron oxidant and in cerimetric titrations against iron(II) solutions.

As an oxidiser, it should be stored apart from organic solvents, paper and other combustibles, ideally on a separate shelf of a chemistry reagent cabinet. Weigh it with a clean, dry spatula, reseal the container promptly, and make up the test reagent fresh for each practical session so that results stay reliable.

Chlorine Water (Product Code: SCL-809/149) is an aqueous chlorine solution used as a ready-made oxidising reagent for halogen displacement and halide tests in school and college chemistry laboratories. Teachers and lab assistants order it in a 500 ml analytical reagent pack, supplied with an MSDS, for qualitative analysis and bleaching demonstrations. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India for teaching laboratories.

Specifications

What Is Chlorine Water Used For?

The most common classroom experiment adds chlorine water to separate solutions of a bromide and an iodide. Chlorine, being the more reactive halogen, pushes out bromine and iodine, and when a non-polar solvent is shaken in, the lower layer turns orange-brown or violet. The same reaction forms the confirmatory layer test for these anions in qualitative analysis, so the reagent sits comfortably in any chemistry teaching kit built around halogens. Dipping moist blue litmus into it shows the solution first turning the indicator red and then bleaching it.

Chlorine escapes slowly from the solution, and the gas irritates the eyes and airways, so open the bottle only in a well-ventilated area or fume cupboard. Keep it tightly stoppered in a cool, dark place, because warmth and light make chlorine water lose strength; run a quick check with a known bromide before a class if the bottle has been open for a while.

Supplier

Chlorine Water is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company that trades as ScienceLab. The company sources analytical reagents such as this one for schools, colleges, dealers and laboratories in India and international markets, so a chemistry department can place its reagent and apparatus enquiry with one supplier.

Frequently Asked Questions

What pack size is Chlorine Water supplied in?
Chlorine Water (SCL-809/149) is supplied in a 500 ml pack of analytical reagent grade solution, together with an MSDS. Schools running halide tests for several sections usually order a few packs at once, because the solution works best while fresh after opening.

Why does chlorine water lose strength after opening?
Chlorine Water loses strength because dissolved chlorine gradually escapes from the solution and also reacts when exposed to light and warmth. Keeping the bottle tightly closed, cool and dark slows this down, and a quick test with a known bromide confirms the reagent still works.

What is the shelf life of Chlorine Water?
The shelf life of Chlorine Water depends on the chemical, its grade and how it is stored, so no fixed period is stated on this page. Ask us for the expiry date of the batch you are quoted through the contact page.

Is an MSDS included with Chlorine Water?
Yes, Chlorine Water is supplied with an MSDS. The sheet explains the irritant nature of chlorine vapour, safe handling in a ventilated area or fume cupboard, and the first-aid steps that teachers and laboratory staff should know before the practical.

Can chlorine water replace bleaching powder in demonstrations?
Chlorine Water demonstrates the bleaching action of chlorine directly in solution, while bleaching powder is a solid source of chlorine used in other experiments. Many chemistry laboratories keep both, because each suits a different part of the practical syllabus.

Who supplies Chlorine Water (SCL-809/149)?
Chlorine Water (SCL-809/149) is supplied by Jain Scientific Equipments Pvt Ltd, which trades as ScienceLab from Ambala, Haryana, India. The company supplies reagents and laboratory items to schools, colleges, dealers and institutions in India and international markets.

D-Glucose Powder Anhydrous (Product Code: SCL-823/156) is water-free glucose powder used as the reference reducing sugar in carbohydrate tests and for making up glucose solutions in school and college laboratories. Chemistry and biology teachers order it as 500 gm of analytical reagent, supplied with an MSDS, for Fehling, Benedict, osmosis and fermentation practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, alongside the school chemistry lab equipment in India that the company offers.

Specifications

What Is D-Glucose Powder Used For?

In food-test and carbohydrate practicals, a small amount of glucose is dissolved in water and heated with Fehling’s solution, Benedict’s reagent or Tollens’ reagent. The brick-red precipitate or silver mirror that appears is the benchmark against which unknown sugars are judged, which is why teachers who stock Benedict solution in school laboratories usually keep a jar of pure glucose too. Molisch’s test with glucose gives the violet ring that confirms a carbohydrate, and comparing glucose with sucrose shows the difference between reducing and non-reducing sugars.

Biology sections use the same powder to prepare sugar solutions of different strengths for osmosis in potato strips or raisins, and to feed yeast in simple fermentation set-ups. Because the anhydrous form picks up moisture from the air, weigh it quickly, keep the lid screwed down, and scoop with a dry spatula so that the powder stays free-flowing.

Supplier

D-Glucose Powder Anhydrous reaches laboratories through Jain Scientific Equipments Private Limited, an Ambala, Haryana company that does business as ScienceLab. The company sources laboratory reagents like this one for schools, colleges and testing laboratories in India and international markets, and quotes them together with the glassware and heating equipment a practical needs. The company profile describes its range and background.

Related Chemistry Lab Products

Reagents and apparatus used with glucose in sugar-testing practicals:

• Fehling A Solution — one half of Fehling’s reagent for the reducing-sugar test.
• Benedict Solution — a single-solution alternative widely used in schools.
• Tollens Reagent — produces the silver mirror with reducing sugars.
• Molisch Reagent — general test that confirms a carbohydrate is present.
• Water Bath — gentle, even heating for a rack of test tubes.

The Chemistry Lab category lists further reagents and glassware.

Frequently Asked Questions

What does “anhydrous” mean for D-Glucose Powder Anhydrous?
D-Glucose Powder Anhydrous is the water-free form of glucose, as opposed to glucose monohydrate. Because the anhydrous powder picks up moisture from the air, keep the lid screwed down and weigh portions quickly with a dry spatula.

How much D-Glucose Powder Anhydrous is in one pack?
Each pack of D-Glucose Powder Anhydrous (SCL-823/156) contains 500 gm of analytical reagent grade D-glucose, supplied with an MSDS. Schools usually weigh out small portions for each practical group rather than opening the main pack at the bench.

Is this glucose meant for eating or clinical use?
No. D-Glucose Powder Anhydrous is supplied as a laboratory reagent for experiments and demonstrations, not as a food or clinical product. Store it in the chemical store, clearly labelled, and never with food items or in a kitchen area.

What is the shelf life of D-Glucose Powder Anhydrous?

Diethyl Ether (Product Code: SCL-825/157) is a highly volatile, extremely flammable organic solvent used to extract compounds from water-based mixtures in college and senior school chemistry laboratories. Organic chemistry and biochemistry labs buy it in a 500 ml analytical reagent pack, supplied with an MSDS, for solvent extraction, lipid solubility tests and reaction work. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a laboratory chemicals supplier in India for colleges, schools and research labs.

Specifications

What Is Diethyl Ether Used For?

A standard exercise is solvent extraction: an aqueous mixture is shaken with ether in a separating funnel, the lighter ether layer is run off, dried over a drying agent such as fused calcium chloride, and then evaporated to recover the dissolved compound. In food-chemistry and biology practicals, a drop of oil shaken with ether and then with water shows clearly which solvent dissolves lipids. College laboratories also rely on dry ether as the medium for Grignard reactions.

Ether vapour is heavier than air and can travel along a bench to a distant flame, so every burner in the room must be off; warm or evaporate ether only on an electric water bath, never over a flame, and preferably inside a chemical fume cupboard. On storage, especially after opening, ether can form explosive peroxides, so date the bottle when first opened, keep it closed, cool and away from light, and never distil or evaporate it to complete dryness.

Supplier

Diethyl Ether is sourced and supplied by Jain Scientific Equipments Private Limited, which operates under the ScienceLab name from Ambala, Haryana. The company provides solvents, reagents and laboratory apparatus to colleges, schools, research laboratories and dealers in India and international markets. More information is available on the ScienceLab profile.

Frequently Asked Questions

What pack size is Diethyl Ether supplied in?
Diethyl Ether (SCL-825/157) is supplied in a 500 ml pack of analytical reagent grade solvent, with an MSDS. Because opened ether can form peroxides, many laboratories prefer to order only the quantity they expect to use during the current teaching term.

Why is diethyl ether more hazardous than most lab solvents?
Diethyl Ether is extremely flammable, its heavy vapour spreads along benches to distant flames, and it can form explosive peroxides on standing. Read the supplied MSDS, switch off every burner, and set clear storage rules before the solvent is used in class.

What is the shelf life of Diethyl Ether?
Shelf life for Diethyl Ether depends on the chemical, its grade and storage conditions, and opened bottles need extra care because of peroxide formation. Ask us for the expiry date of the batch you are quoted, and record the opening date on the label.

Can Diethyl Ether be used in school practicals?
Diethyl Ether can be used in small, supervised volumes in some senior practicals, but only with all flames off and good ventilation. Many schools reserve it for teacher demonstrations of solvent extraction and lipid solubility rather than open student use.

Is additional analysis paperwork available for Diethyl Ether?
Diethyl Ether is listed as analytical reagent grade and is supplied with an MSDS. If your laboratory needs further documents for purchase or audit, please discuss them with us through the contact page before placing the order.

Who supplies Diethyl Ether (SCL-825/157)?

Dimethyl Glyoxime (Product Code: SCL-828/158) is an organic complexing reagent, often shortened to DMG, used to confirm and estimate nickel in qualitative and gravimetric analysis in chemistry laboratories. It forms a striking red precipitate with nickel ions and is packed as 100 gm of analytical reagent with an MSDS for school, college and university practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a chemistry consumables supplier in India.

Specifications

What Is Dimethyl Glyoxime Used For?

In the scheme of cation analysis, nickel is confirmed by making the test solution alkaline with ammonium hydroxide and adding a few drops of DMG dissolved in alcohol. A bright rose-red to cherry-red precipitate appears if nickel is present, a result so distinctive that students rarely mistake it. A teacher preparing a school salt analysis kit therefore keeps a small bottle of the prepared solution in the Group IV reagent set, making it up from the solid as required.

At college level, the same reaction is used quantitatively: the red nickel complex is precipitated from a warm, buffered solution, filtered, washed, dried and weighed to find the nickel content of an alloy or salt. For both uses, weigh the solid carefully, dissolve it fully in alcohol before adding it to the sample, and store the dry reagent in a closed container on a cool, dry shelf.

Supplier

Jain Scientific Equipments Private Limited, which trades as ScienceLab from Ambala, Haryana, supplies Dimethyl Glyoxime as part of its analytical reagent range. It sources reagents for qualitative analysis and quotes them to schools, colleges, universities and dealers in India and international markets. Visit the company profile for more about the company.

Related Chemistry Lab Products

Materials that complete the nickel test and its gravimetric version:

• Nickel Chloride — a known nickel salt for demonstrating the positive result.
• Nickel Sulfate — an alternative nickel sample for practice analyses.
• Ammonium Hydroxide (ammonia water) — makes the solution alkaline before DMG is added.
• Ethanol (ethyl alcohol) — the usual solvent for preparing the DMG test solution.
• Filter Paper — collects the red precipitate in gravimetric work.

Other qualitative analysis reagents are in the Chemistry Lab category.

Frequently Asked Questions

Is Dimethyl Glyoxime supplied as a solid or a ready-made solution?
Dimethyl Glyoxime (SCL-828/158) is listed by weight, 100 gm per pack, so laboratories dissolve it in alcohol themselves to prepare the test solution. If you are looking for a ready-made DMG solution instead, contact us before ordering.

Which metal does Dimethyl Glyoxime detect?
Dimethyl Glyoxime is the classic confirmatory reagent for nickel. In ammoniacal solution it gives a bright rose-red to cherry-red precipitate with nickel ions, a result distinctive enough that students rarely mistake it in the Group IV cation tests.

Why must the solution be ammoniacal for the Dimethyl Glyoxime test?
The red nickel complex of Dimethyl Glyoxime forms properly only in a slightly alkaline medium. In acid solution the precipitate does not appear, so ammonium hydroxide is added to the test solution first, followed by a few drops of the DMG reagent.

What is the shelf life of Dimethyl Glyoxime?
The shelf life of Dimethyl Glyoxime depends on the chemical, its grade and storage conditions, so this page does not quote a fixed period. Ask us for the expiry date of the batch you are quoted, and store the solid closed on a cool, dry shelf.

Is an MSDS supplied with Dimethyl Glyoxime?
Yes, Dimethyl Glyoxime is supplied with an MSDS. The sheet covers safe handling of the solid and of the alcoholic solution prepared from it, together with storage and first-aid information that laboratory staff should read before the practical.

Diphenyl Amine (Product Code: SCL-831/159) is an aromatic amine used as a redox indicator in dichromate titrations and as a colour reagent for nitrates and other oxidising agents in chemistry laboratories. College, school and quality-control laboratories buy it as 100 gm of analytical reagent, supplied with an MSDS, and prepare indicator solutions from it as needed. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, a lab chemicals supplier in India.

Specifications

What Is Diphenyl Amine Used For?

When iron(II) is titrated with potassium dichromate, the end point cannot be seen from the titrant colour alone, so a few drops of diphenylamine indicator solution in sulphuric acid are added to the flask. At the equivalence point, the first slight excess of dichromate oxidises the indicator and the solution turns an intense violet-blue. This titration appears in many undergraduate courses and fits neatly into a volumetric analysis kit alongside Mohr’s salt, dichromate and a burette.

The same compound, dissolved in concentrated sulphuric acid, gives a deep blue colour with nitrates, nitrites and several other oxidising agents, making it a quick spot test in anion analysis and in soil or water investigations. Prepare indicator solutions in small batches, handle the concentrated acid with care, and wear gloves, since diphenylamine is harmful by skin contact and ingestion.

Supplier

Diphenyl Amine is supplied by Jain Scientific Equipments Private Limited, known to customers as ScienceLab, from Ambala, Haryana. The company sources titration indicators and analytical reagents for schools, colleges and industry laboratories in India and international markets. Its export shipments are handled under Importer-Exporter Code AAECJ8618A (DGFT), and buyers completing vendor registration can use its GSTIN 06AAECJ8618A1ZT. Read the company profile for more.

Frequently Asked Questions

How is Diphenyl Amine supplied?
Diphenyl Amine (SCL-831/159) is supplied as 100 gm of analytical reagent grade diphenylamine per pack, with an MSDS. Laboratories prepare the titration indicator or the nitrate test solution from it, usually in concentrated sulphuric acid, in small batches as needed.

What colour change marks the end point with Diphenyl Amine indicator?
With Diphenyl Amine as indicator, the solution turns an intense violet-blue once potassium dichromate is in slight excess over the iron(II) being titrated. Adding phosphoric acid, as many dichromate procedures specify, makes this colour change sharper and easier to judge.

Can Diphenyl Amine tell nitrate apart from nitrite?
No. Diphenyl Amine in concentrated sulphuric acid gives a blue colour with nitrates, nitrites and several other oxidising agents. Use it as a screening test and confirm the anion with a more specific method, such as the brown ring test for nitrate.

What is the shelf life of Diphenyl Amine?
The shelf life of Diphenyl Amine depends on the chemical, its grade and storage conditions, so no fixed expiry period is given on this page. Ask us for the expiry date of the batch you are quoted, and keep the pack closed, dry and away from light.

EDTA N/10 (Product Code: SCL-835/161) is a ready-made EDTA (ethylenediaminetetraacetic acid) titrant solution used for complexometric titrations, above all the determination of water hardness, in chemistry laboratories. Environmental and engineering chemistry courses use this 500ml analytical reagent solution, supplied with an MSDS, to save weighing and dissolving the salt themselves. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India, together with a wide range of chemistry lab equipment in India.

Specifications

What Is EDTA N/10 Used For?

To find the total hardness of a water sample, a measured volume is pipetted into a conical flask, an ammonia buffer and a few drops of Eriochrome Black T indicator are added, and EDTA is run in from a burette. The wine-red colour caused by calcium and magnesium turns clear blue once EDTA has captured all of these ions, and the titre gives the hardness. The experiment is a staple of environmental chemistry and engineering chemistry courses, and a bottle of standard EDTA is a sensible addition to any school titration kit that goes beyond acid-base work.

Beyond hardness, the solution is used to estimate metal ions such as calcium, magnesium and zinc in salts and pharmaceutical samples. For accurate results, check the strength against a standard metal-ion solution when a new bottle is opened, rinse the burette with a little EDTA first, and keep the bottle tightly capped between sessions.

Supplier

EDTA N/10 is supplied by Jain Scientific Equipments Private Limited, the Ambala, Haryana company behind the ScienceLab trade name. It sources standard solutions and titration reagents for schools, colleges, engineering institutes and laboratories in India and international markets, and can quote them with the burettes and flasks the titration needs. The company profile has the details.
