Quick answer: A Stirring Rod with Policeman is a plastic stirring rod fitted with a soft rubber tip (‘policeman’) used to scrape precipitate cleanly off vessel walls during filtration and quantitative analysis in chemistry labs. Stirring Rod, Plastic, Policemen is priced at approximately ₹185 (indicative market benchmark, incl. GST, August 2026).
The Stirring Rod with Policeman combines general-purpose stirring with a specific analytical-chemistry function: the soft rubber tip, called a ‘policeman,’ is used to gently scrape precipitate that clings to the walls of a beaker or flask so it can be fully transferred during filtration. This matters in quantitative analysis, where an accurate result depends on recovering as much of the precipitate as possible rather than leaving some stuck to the glassware. Made from chemically inert plastic, the rod itself is shatterproof compared with a traditional glass stirring rod, while still handling routine mixing and stirring tasks across general chemistry practicals.

Frequently Asked Questions
What is the ‘policeman’ tip for?
It is a soft rubber tip used to gently scrape precipitate off the walls of a beaker or flask, helping ensure complete recovery during filtration for accurate quantitative analysis.
Why use a plastic rod instead of glass?
Plastic is shatterproof and chemically inert, making it a durable, safer alternative to glass for routine classroom and lab handling.
Is this rod suitable for corrosive chemicals?
It is described as chemically inert, but exact chemical-compatibility testing for specific corrosive reagents has not been independently verified for this listing — confirm compatibility with STEMAids for demanding applications.
Does STEMAids supply this in bulk for institutional labs?
Yes — STEMAids supplies laboratory consumables including stirring rods for institutional and bulk orders; contact STEMAids to confirm current quantities and pricing.
Are exact rod length and tip dimensions available for tender specification?
Exact length and tip dimensions have not been independently verified for this listing. Institutions preparing tender documents should confirm precise specifications directly with STEMAids before finalising procurement paperwork.
Is STEMAids a registered manufacturer of this product?
Yes. Eduscope Smart Learning Solutions Private Limited is a Udyam-registered micro manufacturing enterprise (UDYAM-DL-06-0069460) and is ISO 9001:2015 certified. See the About page for full registration and certification details — manufacturer-stated, verify before citing in procurement documents.
