GL45 Vented Caps for Sterilization
BIOVENT® GL45 vented caps serve as the ideal closures for laboratory bottles used for sterilising and storing media or buffer solutions. They are suitable for aerobic microbial, shaker, and suspension cell cultures. These caps feature a sPTFE membrane that facilitates sterile gas exchange while preventing the entry of contaminants and liquids.
FEATURES & BENEFITS
BIOVENT® Caps address the issues of contamination and bottle failure due to vacuum & pressure build-up during autoclaving cycles.
The sPTFE membrane’s microporous structure allows bi-directional sterile gas exchange while blocking liquids and contaminants. This enables pressure equalisation, allowing sterilisation in an autoclave with the screw cap tightened, ensuring the sterility of the bottle contents.The sPTFE membrane is ultrasonically welded to the cap, forming a durable seal.
The caps are reusable multiple times, reducing cost.
Properties
- The sPTFE membrane has a pore size of 0.1 µm. Combined with large venting windows in the cap, it allows efficient gas exchange
- The caps can withstand autoclaving at 121°C for 20 minutes or 134°C for 3 minutes
- The caps are resistant to temperatures up to 140°C
Material Compliance
- The sPTFE filter material is biocompatible, conforming to USP Class VI
- >99.999% Bacterial Filtration Efficiency (BFE)
- Free from perfluoro-octanoicacid (PFOA)
- Free of animal derived components (ADCF)
