Rasayan Class B Burettes With Ptfe Key Stopcock

Rasayan Class B burettes with PTFE key stopcocks are laboratory instruments used for volumetric measurements and titration experiments. Here's an overview of the components and their functions: Rasayan Class B Burette: The burette is a long, graduated glass tube with volume markings along its length. Class B burettes are manufactured with a slightly lower level of accuracy compared to Class A burettes but are still suitable for many analytical applications. They provide accurate measurements within acceptable tolerances for most laboratory work. PTFE Key Stopcock: The PTFE (polytetrafluoroethylene) key stopcock is a valve mechanism located at the bottom of the burette near the tip. It controls the flow of liquid from the burette. PTFE is chosen for its chemical resistance and non-reactivity with most substances. The key design enables precise control over the flow rate, allowing for accurate titration.
