Burette with PTFE Key Stopcock Manufacturer,Supplier and Exporter in India
Product Code : TVT-GP-10769
The Burette with PTFE Key Stopcock is a Class AS borosilicate glass 3.3 burette manufactured on computer-controlled machinery for tight dimensional accuracy, fitted with a PTFE key stopcock for precise titrant delivery.
How It Works
Manufactured on computer-controlled machinery, the burette achieves the tight bore and graduation accuracy required for Class AS (rapid-delivery, high-precision) classification. Its PTFE key stopcock provides smooth, leak-free flow control that is unaffected by most laboratory chemicals, avoiding the grease-sealing and sticking issues that can affect a glass stopcock. Blue enamel printing on the borosilicate glass 3.3 body gives clear, chemical-resistant graduation markings for accurate volume reading throughout a titration.

Frequently Asked Questions
What does Class AS mean for this burette?
Class AS refers to the rapid-delivery, high-precision accuracy grade defined in ISO 385 for burettes.
Why use a PTFE stopcock instead of glass?
A PTFE key stopcock provides smooth, leak-free flow control that resists most laboratory chemicals without the sticking or grease-sealing issues of a glass stopcock.
What glass is this burette made from?
It is made from borosilicate glass 3.3, chemical resistant with blue enamel graduation printing.
