Screw Caps for Cell Culture Flasks

Two types of screw caps are available for TPP culture flasks:

1. Filter cap: a 0.22 µm PTFE membrane allows sterile gas exchange via the cap openings

2. VENT cap: turn the screw cap until the "click" for aeration. Turn the cap mark to the "3 o'clock" position for gas-tight closure.
