Rasayan Burettes Mounted on Reservoir with PTFE key Stop Cock

Rasayan burettes mounted on reservoirs with PTFE key stop cocks are specialized laboratory instruments used for precise volumetric measurements, particularly in titration experiments. Here's a breakdown of the components and their functions: Rasayan Burette: The burette is the main component used for delivering precise volumes of liquid. It typically has volume markings along its length, allowing for accurate measurement of the liquid dispensed. Reservoir: The reservoir, usually made of glass, is attached to the burette. It holds the liquid (often the titrant solution) that will be dispensed through the burette during the titration process. Having the liquid in a reservoir ensures a continuous and steady flow during titration. PTFE Key Stop Cock: The stop cock is a valve mechanism located at the bottom of the burette, near the tip. It controls the flow of liquid from the burette. PTFE (polytetrafluoroethylene) is a common material used for the stop cock due to its chemical resistance and non-reactivity with most substances. The key design allows for precise control over the flow rate, enabling accurate titration.
