Ammonium Sulfate
Ammonium Sulfate (Product Code: SCI-405/169) is an analytical reagent grade ammonium salt used for salt-analysis practice, fertiliser chemistry and protein precipitation in school, college and biology laboratories. It comes in a 200 g pack with its MSDS, a straightforward addition for chemistry teachers assembling a salt analysis kit for school practicals. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, India.

What Is Ammonium Sulfate Used For?
Ammonium sulfate is a common unknown in qualitative analysis because both of its ions give clean, visible results. Warming a little of the salt with sodium hydroxide releases ammonia, recognised by its sharp smell and by turning damp red litmus paper blue. Its solution gives a white precipitate with barium chloride that does not dissolve in dilute hydrochloric acid, which confirms the sulfate.
Agriculture and environmental science lessons use it as an example of a nitrogen and sulphur fertiliser, and to explain why heavy use of ammonium fertilisers tends to make soil more acidic. In biology and biochemistry, concentrated ammonium sulfate solution is used to salt out proteins such as egg albumin, a simple first step in protein purification. Store it away from strong alkalis, since the two together release ammonia.
What to Specify When Ordering
- How many 200 g packs each laboratory or store needs.
- The main use (salt analysis, fertiliser demonstrations or protein work), so we can check the reagent suits your method.
- Companion items for the same enquiry, such as sodium hydroxide, red litmus paper or barium chloride.
- The product code you want, because the catalogue also has a separate Ammonium Sulfate 200 g listing.
Supplier
ScienceLab, the trading name of Jain Scientific Equipments Private Limited in Ambala, sources Ammonium Sulfate for chemistry, agriculture and biology laboratories and sends it in 200 g packs with the MSDS. As a lab consumables supplier in India, the company can combine it with litmus paper, glassware and other reagents on one quotation for schools, colleges, dealers and importers in India and international markets. More about the company is on the ScienceLab profile.

Frequently Asked Questions
How do you test Ammonium Sulfate for the ammonium ion?
To test Ammonium Sulfate for the ammonium ion, warm a small sample with sodium hydroxide solution in a test tube. Ammonia gas is released, which smells sharp and turns damp red litmus paper blue; carry out the test in a well-ventilated area.
Can Ammonium Sulfate be used for protein precipitation?
Yes. Ammonium Sulfate is widely used to salt out proteins, because high salt concentrations lower protein solubility. Ammonium Sulfate SCI-405/169 is analytical reagent grade in a 200 g pack, so tell us the amount your method uses and we will quote the right number of packs.
Is Ammonium Sulfate SCI-405/169 a field fertiliser?
No. Ammonium Sulfate SCI-405/169 is an analytical reagent for laboratory teaching and analysis, not a bulk field fertiliser. Schools and colleges use it to demonstrate how nitrogen fertilisers behave in soil and water, working from its 200 g pack and MSDS.
How should Ammonium Sulfate be stored?
Keep Ammonium Sulfate SCI-405/169 in its closed container in a cool, dry cabinet, apart from alkalis and oxidising agents. Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted.
Who supplies Ammonium Sulfate SCI-405/169?
Ammonium Sulfate SCI-405/169 is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, Haryana, India. The company sources the reagent and provides it with its MSDS to schools, colleges, agricultural and biology laboratories, and dealers in India and international markets.
What details does an Ammonium Sulfate quotation need?
An Ammonium Sulfate quotation needs the product code SCI-405/169, the number of 200 g packs, your delivery location and any companion reagents. Send these through our contact page or enquiry cart and we will reply with the quotation.
