The PTFE stirring rod adapter is a component designed to ensure a secure and hermetic seal in laboratory stirring systems, especially in flasks and reactors.
Manufactured from polytetrafluoroethylene (PTFE), this adapter offers excellent chemical and thermal resistance, making it suitable for demanding applications in scientific, chemical, and pharmaceutical environments.
The system incorporates an FPM elastomer sealing gasket that is compressed by a standardized GL thread, allowing for a precise fit over the stirring rod, whether glass or stainless steel.
Operating Characteristics
Hermetic seal: ensures tightness under vacuum conditions
Fluid rotation: allows continuous movement of the rod without loss of seal
Compatibility: suitable for standard diameter stirring rods
Glass protection: design minimizes stress and risk of breakage
Technical Characteristics
Main material: PTFE (polytetrafluoroethylene)
Sealing system: FPM elastomeric gasket
Compatibility: Glass or steel stirring rods
Connection: Standard ground glass joint (various sizes)
Temperature range: -270 °C to 270 °C
Chemical resistance: Excellent against reagents and solvents
Sterilization: Suitable for standard methods (except gamma radiation)
Certification: FDA and USP Class VI
