Seals for bacteria culture flasks

Seals for bacteria culture flasks

AirOtop Enhanced Seals (patented) are disposable, high gas exchange, sterile, simple seals for all shake flasks. Properties of the seal include a 0.2μm sterile barrier with a resealable membrane for use with Ultra Yield Flasks as well as other brand flasks. Multiple sizes are available to work with most commercially available shake flasks. Testing has been conducted by multiple customers with great results of up to 24-hours of growth. Testing included Protista (Algae), E. coli, and other microbes, and resulted in improved growth and more aerobic growth for all lines tested. Testing also showed that the pH of the cultures was more neutral.

How do they work?
AirOtop Enhanced Seals can be applied as a clean, sterile barrier that allows samples to vent while preventing contamination from condensation and airborne particles such as phage, mold, spores, and dust. AirOtop Enhanced Seals replace plastic & metal flask caps, aluminum foil over flasks, cotton plugs, or cheese cloth. AirOtop Enhanced Seals are a convenient seal for many different types of flask. When used in combination with the Ultra Yield flasks they become a simple “High yield production system”. The combination of Ultra Yield Flasks and AirOtop Enhanced Seals allows maximum gas exchange improving production yields.
