Enhanced Flask Seal™

U.S. Patent 7,381,559. U.K. Patent 2414994

Enhanced AirOtop Seals (patented) are simple, disposable, sterile High Air Exchange seals for all shake flasks. The Enhanced AirOtop Seal's properties include a .2um sterile barrier with a long term resealable membrane for use with Ultra Yield and other brand flasks. Multiple sizes are available to keep all of your flasks covered. Testing has been conducted on multiple customer samples with great results on up to 7 days of cellular growth. This testing included Protista (Algae), E.coli and other microbes which, has all resulted in improved growth and more aerobic growth. Also, showing that the pH of the cultures were more neutral.

Why do they work?

Enhanced AirOtop Seals (patented) 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. Enhanced AirOtop Seals replace plastic & metal flask caps, aluminum foil over flasks, cotton plugs, cheese cloth, etc. Enhanced AirOtop Seals are a convenient seal for all different flasks. When used in combination with the Ultra Yield Flasks they become a simple "Disposable Bioreactor" at a fraction of the price. Maximum aeration results from an Ultra Yield Flask using an Enhanced AirOtop Seal.
