Sulphosalicylic Acid
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.

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.

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.
What details are needed for a Sulphosalicylic Acid tender or purchase order?
For a tender or purchase order for Sulphosalicylic Acid, include the product code SCL441/0129, the number of 500 g packs, the delivery address and your billing format, so the quotation matches your institution's paperwork.
