A Dropping Funnel is a type of laboratory glassware used for the precise dispensing of liquids in a dropwise manner. It is typically used in chemical reactions where small, accurate amounts of reagents need to be added.

A Cylindrical Dropping Funnel is a type of dropping funnel that has a cylindrical shape. This design allows for precise control of the liquid flow and helps prevent spills and drips.

A PTFE Stopcock is a type of stopcock valve made of polytetrafluoroethylene (PTFE), a material known for its chemical resistance, non-stick properties, and low friction. The valve consists of a cylindrical body with an opening that can be opened or closed by turning a knob or lever, allowing liquids to flow through or stopping the flow. PTFE stopcocks are commonly used in laboratory settings due to their chemical resistance and ease of use.
