Thomson Ultra Yield™ Solution

Thomson’s Ultra Yield™ Flasks (patented) have proven over the last decade to enhance the growth of E. coli & other microbial cells. The patented flask design makes them the workhorse of protein and DNA labs worldwide. The Ultra Yield™ Flasks come in standardized sizes of 125mL, 250mL, 500mL, and 2.5L.

The flasks are designed to be closed on top by using our AirOTop™ Enhanced Seals (patented). These seals are designed to fit on the tops of the flasks. AirOtop™ Enhanced Seals are sterile, easy to use, and single use. AirOtop™ properties include a 0.2μm re-sealable and sterile membrane barrier providing high air exchange for all types of shake flasks. Multiple sizes are available to keep all of your flasks covered. Testing has been conducted at multiple customer sites with great results on up to 24-hours of growth. The organisms tested included Protista (Algae), E. coli, and other microbes which have resulted in improved cell density, a more neutral pH of the cultures with the increased gas exchange.
