Thomson Instrument Company Optimum Growth 500mL Flask w/ Vent Cap, 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 and sterilized for cleanroom-ready use
•Made in the USA with most products available for same-day shipping

CELLTREAT Scientific Products 125mL Erlenmeyer Flask, Vent Cap, Plain Bottom, PC, Sterile
Designed for mammalian suspension culture applications as well as bacterial & yeast culture. Polycarbonate available with vent cap only. Vent caps with over-sized vent area feature 0.22μm hydrophobic membrane which allows for improved gas exchange without contamination. Avoid contamination with single-use, pre-sterilized flasks. Lightweight material is easier to handle than glass. Flasks include molded graduation lines. Individually bagged for easy storage and handling. Medical grade virgin Polycarbonate is autoclavable.
CELLTREAT Scientific Products 125mL Erlenmeyer Flask, Vent Cap, Baffled Bottom, PC, Sterile
Lightweight plastic material is easier and safer to handle than glass. Designed for mammalian suspension culture applications as well as bacterial & yeast culture. Baffled flasks enhance both vertical and circular culture movement to improve aeration. Vent cap options are available to prevent the common mistake of unintentionally sealing the cap completely and preventing gas exchange. All flasks include molded graduation lines and feature a molded 1/3 fill line to help ensure optimal working volumes. Individually bagged for easy storage and handling. Medical grade virgin Polycarbonate is autoclavable (temperature range of -80°C – 121°C). Working volumes are recommendations only; optimize as required for individual protocols.
