Why Choose a PTFE Needle-Valve Stopcock and Amber Graduations
A PTFE needle-valve stopcock does not need grease and is resistant to most laboratory reagents, which is why it is a common alternative to a glass key stopcock on routine-use burettes such as the Burette Class B With PTFE Key Stopcock.
Amber-printed graduations improve the visibility of the printed scale and are a traditional choice on burettes used for titrations involving light-sensitive reagents, such as iodometric titrations. Buyers who need a glass-stopcock version instead can see the Burette Class B With Glass Stopcock.
