Sampling Flasks
Optimum Growth® Sample Flasks with one-way sampling valves that help reduce viable cell count sampling times and eliminate the need to remove flask caps & allow aseptic sampling on the benchtop
Choose one from each option to find the perfect match.
Several Options for aseptic Sampling
Optimum Growth® Flasks provide several options for aseptic sampling in all flask sizes. The 125mL, 250mL, and 500mLOptimum Growth® Flasks have an optional 1-way valve in the vented sample cap. The 5L Optimum Growth® Flask has an optional 1-way valve in the side of the flask.
The aseptic sampling option is available for the 125mL, 250mL, 500mL & 5L Optimum Growth® Flasks.
Vented Sampling Caps
The Vent Cap of the Optimum Growth® Sampling Flask incorporates a 1-way valve that only allows media to flow out of the flask. This eliminates contamination and allows for aseptic sampling of cells while the flasks remain in the shaker or on the benchtop, eliminating the need for transfer to the hood from the shaker.
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.
Sampling in the Shaker
Thomson's improved sampling method allows you to sample directly in the shaker without the need to remove caps or use a deteriorating needle septum.
