Sigma Aldrich Fine Chemicals Biosciences TPPR tissue culture flasks
The inside surface treatment by TPP provides an optimal growth surface on the flask base for the most varied matrix-dependent tissue cultures. The untreated side and top inside surfaces reduce the amount of cell loss during the separation phases because undesired tissue adhesion outside the growth zone is diminished. The flasks innovative shape is of such a design that devices inserted through the flasks neck have optimal access to the entire base surface. This means that there are no dead corners that cannot be reached with pipettes or cell scrapers.This excellent accessibility is due to the large neck opening and the favorable angle of inclination. The angled neck also reduces the chance of accidental spills and permits dribble-free pouring.When the vented screw cap is tightened to the end position the closed tissue culture flask is liquid and gas tight. By simply unscrewing the cap one quarter of a turn the flask is in the VENT position with the inside of the flask being aerated

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
Thomson Instrument Company Multiported Optimum Growth 1.6L Flask, Sterile
Thomson’s Optimum Growth Multiport Flasks offer integrated ports that enable closed-system feeding, sampling, and media transfer—supporting sterile workflows without the need to open the flask, even during extended culture periods.
•Available in 125mL, 250mL, 500mL, 1.6L, 2.8L, 5L and 7L sizes.
•One-way sampling valve allows safe and aseptic sampling while the flask remains in the shaker or on the benchtop
•Two-way Luer lock port supports sterile feeding, inoculation, and direct media transfer to larger vessels
•Closed system design helps maintain sterility throughout use, reducing contamination risk and supporting GMP compliance
•Eliminates the need for cell bags up to 50L, reducing cost and complexity
•Compatible with multi-day batch feeding in shaker environments
•Includes sterile, pre-attached tubing for plug-and-play integration into cleanroom workflows
• Made in the USA
Thomson Instrument Company Optimum Growth 5L Flask w/ Port, Sterile
Thomson’s Optimum Growth Sampling Flasks feature integrated one-way valves that enable aseptic sampling directly in the shaker or on the benchtop, helping reduce contamination risk and improve efficiency—especially in high-throughput environments.
•Available in 125 mL, 250 mL, 500 mL, and 5 L sizes with integrated one-way sampling valves
•Aseptic sampling without removing the cap—simply connect a syringe and collect samples
•Enables sampling without removing flasks from shakers or moving them to biosafety cabinets
•Streamlines workflows and minimizes time, contamination risk, and handling complexity
•0.2 µm PTFE vented caps support sterile gas exchange and maintain culture integrity
• Made in the USA

Chemglass Life Sciences Flask, Shake, 125mL, Deep Baffles, Delong Neck, Approx OD x Height (mm): 70 x 145
Flask, Shake, 125mL, Deep Baffles, Delong Neck, Approx OD x Height (mm): 70 x 145. Extra deep baffle indents on the lower outside edge of the flask to maximize oxygen transfer to the culture medium when used on an orbital shaker. Delong style neck is made to fit stainless steel or plastic closures, while the longer neck reduces the amount of splashing that would reach the closure.
