Thomson Instrument Company Ultra Yield 2.5L 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
•Made in the USA with reliable, fast shipment
Alkali Scientific Erlenmeyer Shake Flask, PETG, flat bottom w / vented screw cap, sterile, indiv wrapped, 1000mL, 6/cs
• Vented screw caps • Flat or baffled bottoms • Gamma sterile (SAL 10-6) • Pyrogen free and RNase/DNase free • Individually wrapped Erlenmeyer Shaker Flasks are made of polycarbonate, PETG or styrene/butadiene (Jumbo Flasks only). The polypropylene screw caps are vented with 0.2µm membranes to increase air transmission and enhance cell growth. The mouth size conforms with the international SBS standard, for quick, secure connection to bioreactor equipment.Polycarbonate flasks and Jumbo Fernbach flasks have baffled (ribbed) bottoms to provide increased oxygenation and mixing efficiency even at lower shaking speeds. All flasks, regardless of size, are individually wrapped and gamma sterilized to SAL 10-6, and they are free of RNase, DNase, pyrogen, endotoxins and human DNA. Polycarbonate Flasks are autoclavable at 121°C and 15PSI for 30 minutes.

Thomson Instrument Company Optimum Growth 5L 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
