Nesslers Reagent Manufacturer,Supplier and Exporter in India

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.

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.

Frequently Asked Questions

Who supplies Nesslers Reagent SCL-903/194?
Nesslers Reagent (SCL-903/194) is supplied by Jain Scientific Equipments Pvt Ltd, trading as ScienceLab, of Ambala, Haryana, India. The company sources this analytical reagent and sends each 100 ml bottle with its MSDS to schools, colleges and testing laboratories in India and international markets.

What colour change does Nesslers Reagent give with ammonia?
Nesslers Reagent turns yellow when small traces of ammonia or ammonium ions are present, and the colour deepens to an orange-brown precipitate as the amount rises. Comparing each tube against a distilled-water blank made with the same reagent helps students notice faint positive results.

How many tests does a 100 ml bottle of Nesslers Reagent cover?
A 100 ml bottle of Nesslers Reagent covers a large number of student tests, because each confirmatory test or water sample needs only a few drops. The exact count depends on how many drops your method uses per tube and how many students share a bottle.

Is Nesslers Reagent hazardous to handle?
Yes. Nesslers Reagent is a toxic, strongly alkaline mercury-based solution. Dispense it with a dropper, wear gloves and eye protection, and collect used solutions as heavy-metal waste rather than pouring them down the sink. The MSDS supplied with every bottle gives handling, first-aid and disposal instructions.

What is the shelf life of Nesslers Reagent?
Shelf life depends on the chemical, its grade and storage conditions; ask us for the expiry date of the batch you are quoted. Keep the Nesslers Reagent bottle tightly closed, away from light and acids, and replace it if heavy sediment or strong discolouration develops.

Can Nesslers Reagent be used for quantitative ammonia measurement?
Nesslers Reagent is widely used for visual colour-comparison work in teaching labs. If you plan quantitative ammonia measurement with a colorimeter, share your method requirements through our contact page before ordering so we can confirm the reagent suits it.

Can Nesslers Reagent be shipped outside India?
Export of Nesslers Reagent depends on dangerous-goods rules, because it is a toxic reagent. We serve customers in India and international markets; tell us the destination country and number of bottles and we will confirm which shipping options are possible before quoting.
