The Optimum Growth™ Flasks provide several options for aseptic sampling in all flask sizes. The 125mL, 250mL, and 500mL Optimum Growth™ Flasks have an optional 1-way valve in the vented sample cap. The 5L Optimum Growth™ Flasks has an optional 1-way valve in the side of the flask.
Vented Sampling Cap
The Optimum Growth™ Sampling Cap is ventilated for optimal cultivation and has a 1-way valve built into it. This reduces contamination and allows for aseptic sampling of cells while the flasks remain in the shaker, eliminating the need for transfer to the hood from the shaker.
The Optimum Growth™ Sampling Flasks come with a 0.2μm PTFE vented cap for optimum aeration during cultivation. The Thomson vented caps create a safe aseptic barrier from harmful contaminants, while the large surface area creates an optimum air exchange for cell growth.
