Quick answer: This Burette uses a screw-type glass stopcock mechanism, giving fine, controlled adjustment of liquid delivery during titration. Burette, Screw Type Glass Key is priced at approximately ₹300 (indicative market benchmark, incl. GST, August 2026).
A burette is a long, graduated glass tube used to deliver a precisely measured, variable volume of liquid reagent during a titration. This version uses a screw-type glass key mechanism, where turning a threaded screw incrementally opens or closes the stopcock, giving fine, controlled adjustment of flow rate. Made from borosilicate 3.3 glass for chemical resistance, it’s a standard instrument for titration in college and research analytical chemistry laboratories.

Frequently Asked Questions
What is a screw-type glass key burette used for?
It’s used for titration, giving fine, incremental control over reagent flow rate via a threaded screw mechanism on the glass stopcock.
What capacity does this burette hold?
The exact capacity and graduation increments have not been independently verified for this listing — confirm with STEMAids before ordering.
What’s the difference between this and a straight bore glass key burette?
The screw-type mechanism gives finer, more incremental flow adjustment compared to a straight-bore key, which is a simpler on/off style stopcock.
Is this suitable for a college chemistry teaching lab?
Yes — burettes of this kind are standard equipment for titration practicals in analytical chemistry coursework.
Does STEMAids supply matching burette stands and clamps?
Contact STEMAids to confirm compatible support equipment for a complete titration setup.
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.
