Our PTFE mixing plug (or stirrer stopper/bearing adapter) is provides a safe, sealed entry point for a stirring rod into a reaction flask or vessel. It combines the functions of a standard stopper with a low-friction bearing to facilitate mechanical stirring in chemically aggressive or temperature-controlled environments.
Key Features:
The primary function of a PTFE mixing plug is to create a secure, chemical-resistant seal around a moving stirrer shaft, often inside a ground glass joint flask.
Sealing: It creates a tight seal using an O-ring and a screw cap system (e.g., GL 25 cap) to isolate the reaction mixture from the external atmosphere, which is crucial for air-sensitive or anaerobic reactions.
Stirring Support: It acts as a low-friction bearing for the stirrer shaft (typically an 8mm diameter rod), allowing the shaft to rotate smoothly with minimal wear or friction.
Chemical Inertness: Made entirely of PTFE, it is resistant to nearly all corrosive chemicals and solvents, including strong acids like hydrofluoric acid and aqua regia, ensuring no contamination of the reagents.
Temperature Tolerance: It can operate across a wide temperature range, typically from -200°C to +250°C, making it versatile for various experimental conditions.
Applications:
Chemical Synthesis: Essential for complex organic and inorganic syntheses where precise control over the environment (e.g., inert atmosphere) and efficient mechanical stirring are needed.
High-Purity Work: Used in trace element analysis (e.g., ICP-MS sample preparation) to prevent metal ion leaching that can occur with glass or metal components.
Corrosive Environments: Provides a reliable solution for mixing highly corrosive media that would degrade standard rubber stoppers or metal bearings.
Biochemical and Medical Research: The non-toxic and physiologically inert properties make them safe for use in sensitive biological and medical applications where contamination is a concern
