CELLTREAT Scientific Products 1000mL Erlenmeyer Flask, Vent Cap, Plain 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.

•Includes sterile, pre-attached tubing for plug-and-play integration into cleanroom workflows
• Made in the USA
Thomson Instrument Company Ultra Yield 500mL Flask, Sterile
Ultra Yield Flasks are sterile, single-use shake flasks engineered for max oxygen transfer and high-density growth. Their high-aeration geometry, used on standard orbital shakers, drives faster cultures and cleaner downstreams. Pair with AirOtop Enhanced Seals or Vented Screw Caps; with Plasmid+ Media, customers have reported plasmid yields up to 610%.Key features
•High-aeration geometry/baffled base to boost OTR and mixing
•Sterile, ready-to-use single-use format for low contamination risk
•Sizes from 125 mL to 2.5 L for bench-to-pilot scalability
•Engineered for high-rpm orbital shaking (stable, leak-tight operation)
•Closure flexibility: AirOtop seals, Vented Screw Caps, or Bidirectional Transfer Caps
•Clear graduations & label area for easy sampling and tracking

Chemglass Life Sciences Flask, Erlenmeyer, 2000mL, Sterile, Baffled, Polycarbonate, 53-B, with Blue Duo Cap, BULK PACK
Flask, Erlenmeyer, 2000mL, Sterile, Baffled, Polycarbonate, 53-B, with Blue Duo Cap, BULK PACK. Quadruple baffled Erlenmeyer flasks are sterile, non-pyrogenic and manufactured with polycarbonate resin. Flasks are supplied with exclusive DuoCap designed for both aerobic and anaerobic applications (for aerobic applications the cap utilizes a 0.22m pore size PTFE membrane for sterile air exchange; for anaerobic applications the cap can easily be converted to a solid cap design). Solid top caps are also ideal for applications requiring mixing, shaking and storage of biological fluids. Graduations are molded for accuracy.EZ-Tear packaging allows for easy access.
Thomson Instrument Company Optimum Growth 2.8L 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
