GL45 Vented Caps for Sterilization with PTFE Membrane
GL45 vented caps are designed as closures for laboratory bottles used for sterilizing and storing media or buffer solutions. They are suitable for aerobic microbial culture, shaker culture, and suspension cell culture applications that require sterile gas exchange.
Product Features
-
GL45 compatibility: Compatible with most GL45 reagent bottles, including blue cap bottles of various capacities.
-
PTFE membrane: Supports bi-directional sterile gas exchange while helping block liquids and contaminants.
-
Pressure equalization: Allows pressure equalization during autoclaving so the screw cap can remain tightened while helping maintain bottle content sterility.
-
Improved sealing ring design: Designed for compatibility with GL45 reagent bottles and polypropylene plastic reagent bottles.
-
Ultrasonic welding: The PTFE membrane is ultrasonically welded to the cap to form a durable seal.
-
Reusable under normal use: The caps can be reused multiple times under normal usage conditions, helping reduce laboratory consumable cost.
Sterilization Resistance
- Withstands autoclave sterilization cycles at 134°C for 15 minutes.
Applications
- Sterilization and storage of media or buffer solutions
- Aerobic microbial culture
- Shaker culture
- Suspension cell culture
- Pressure equalization during autoclaving
- GL45 laboratory reagent bottles and blue cap bottles
