Description

General description

Antifoam function as an effective foam suppressor. Antifoam 204 contains 100% active components and is a mixture of organic non-silicone polypropylene-based polyether dispersions. It does not contain mineral oil. Antifoam 204 can itself be considered a surfactant, but it contains no other surfactants. This product is synthetic and not derived from animal or plant sources. Antifoam 204 can be sterilized repeatedly. The flow properties of Antifoam 204 are such that it can be pumped to a fermenter on an as-needed basis. For use in microbiological media, Sigma recommends a starting concentration of between 0.005% and 0.01%.

Application

Antifoam 204 has been used:

• to suppress bubbling in thylakoid solutions during intramembrane isoprene quantification
• as a component of fed-batch continuous culture fermentation medium
• to suppress severe foaming in fermenter

Features and Benefits

• Highly versatile surfactant for your cell biology and biochemical research
• Suitable for microbiological culture

Other Notes

Contains 100% active components and is a mixture of non-silicone organic defoamers in a polyol dispersion. Can be sterilized repeatedly.
