Thomson Instrument Company Optimum Growth 500mL Flask, Double Bagged, Sterile
Thomson’s patented Optimum Growth Flasks are engineered for mammalian and insect cell culture, supporting applications from research to production. Available in 125mL, 250mL, 500mL, 5L and 7L sizes, these flasks support 40–50% fill capacity (vs. 33% in traditional shake flasks) and maintain consistent performance across scales—making them a leading choice for modern bioprocessing workflows.
•Higher culture volume per flask helps grow more cells in the same shaker space, increasing throughput
•Same footprint as standard Fernbach flasks, but with greater media capacity and less foaming
•Unique low shear baffle design increases aeration while preserving cell viability
•0.2μm PTFE vented cap maintain sterility and efficient gas exchange
•Easier to handle than bioreactor bags or bioprocess containers.
•Individually packaged, double-bagged, and sterilized for cleanroom-ready use
•Made in the USA with most products available for same-day shipping
