Description
Burette stopcock for compact burettes and titration apparatus is a PTFE component supplied without a burette tip. Designed for precise flow control, this stopcock integrates into compact burette and titration systems used in volumetric analysis and quantitative chemistry. The PTFE construction provides excellent chemical resistance toward a broad spectrum of titrants, solvents and reagents commonly encountered in laboratory titration work. Offered as a single piece, the stopcock is ready for installation in compatible apparatus. From manufacturer Brand, it supports accurate dispensing, reliable sealing and smooth operation during repeated titration cycles. The absence of an integrated burette tip allows flexible pairing with existing tips or custom configurations according to the specific titration setup. Suitable for educational laboratories, research environments and quality-control departments, this accessory maintains consistent performance under routine analytical conditions. Its durable PTFE material ensures low-friction movement and long service life while preserving the precision required for reliable endpoint determination and volumetric measurements.
This article is part of Burettes, in Volumetric glassware.

Questions about Stopcock for compact/automatic burettes, PTFE, without burette tip
What is this article?
Stopcock for compact/automatic burettes, PTFE, without burette tip is the article on this page. Luminix Health distributes Brand for laboratory use. It sits in Burettes, inside Volumetric glassware, in Labware.
A burette delivers a measured volume through a stopcock, which is how a titration is read. Class A and class AS state the tolerance. The stopcock, glass or PTFE, and the volume of the burette are the choices. A dirty bore changes the delivered volume.
Volumetric glassware is glass that has been calibrated to contain or to deliver one stated volume at a reference temperature. That calibration is the whole point. Class A and class AS have a tighter tolerance than class B. A volumetric flask contains. A pipette and a burette deliver. A measuring cylinder is the coarser reading, used when the volume is not the result. The classes sit under ISO laboratory glassware. The chain back to the unit of volume is the work of the BIPM and of NIST.
