Thomson Optimum Growth Flask – 125mL to 5L

Designed for mammalian and insect cell culture, superior to traditional shake flasks making shake cabinets a much more efficient space in the lab.

Thomson Optimum Growth™ Flasks (patented) for mammalian and insect cell culture come in multiple sizes of 125mL, 250mL, 500mL, 1.6L, 2.8L and our popular 5L. They are superior to traditional shake flasks due in part to the fact that they support a 50-60% fill volume versus 33% fill volume making your shake cabinet a much more efficient space.

  • Gives excellent growth
  • Space saving capability
  • Individually packaged and sterilized
  • Baffles designed for high aeration and low shear to maintain cell viability
  • Same footprint as comparable Fernbach flask but with a 50-60% fill volume
  • Less foaming than disposable Fernbach potentially eliminates additives
  • 0.2μm Vented Cap simultaneously maintains high gas exchange and sterility
  • Transfer cap option connects directly to cell bags or bioreactors with multiple connection options
  • Scalability from 125mL up to 5L lets you mix and match different flask sizes in your shaker greatly improving space efficiency
  • Individually packaged and sterilised for immediate use
