Quick answer: This Straight Bore Burette uses a glass stopcock (key) to control the precise, drop-by-drop delivery of a liquid reagent during titration. Burette, Straight Bore Glass Key is priced at approximately ₹335 (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 straight-bore glass stopcock (key) at the bottom to control flow — turning the key opens a straight channel through the glass, letting the user control the rate of delivery down to individual drops. Made from borosilicate glass, it’s a standard instrument for titration in college and research analytical chemistry laboratories.

Frequently Asked Questions
What is a straight bore glass key burette used for?
It’s used to deliver a precisely controlled, variable volume of liquid reagent during titration, using a glass stopcock to control the flow rate down to individual drops.
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 STEMAids’ PTFE key or Rotaflow burettes?
This version uses a glass-on-glass stopcock, which needs greasing; STEMAids also lists PTFE-key and Rotaflow versions that use different stopcock mechanisms — choose based on your preference for maintenance and chemical compatibility.
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.
