Antifoam 204
Mechanism of foam breakage by a defoamer. This inolves spreading of an water-insoluble surfactant on the bubble surfaces.
Application & Uses
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
Dosage & Directions for Use
Features and Benefits
- Highly versatile surfactant for your cell biology and biochemical research
- Suitable for microbiological culture
Other Notes
Product Description & Chemical Profile
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%.
