A burette with a straight bore PTFE key stopcock, Class B is a type of laboratory glassware used for accurate measurement and dispensing of liquids. A burette is a long, narrow tube with a stopcock that allows for precise control of the flow of liquid.
The straight bore PTFE key stopcock is a type of stopcock that has a key mechanism for controlling the flow of liquid, made from Polytetrafluoroethylene (PTFE), a chemical-resistant material. Class B burettes have a higher level of accuracy compared to other classes, with a tolerance of +/- 0.05 mL.
The burette is commonly used in a variety of laboratory applications, including titrations and chemical reactions, where accurate measurement and dispensing of liquids is important. The straight bore PTFE key stopcock, Class B burette is an important piece of laboratory glassware and is widely used in chemical and analytical laboratory applications.
