Descrizione generale
Antifoam A Concentrate is an extremely effective foam suppressor for aqueous and non-aqueous systems. It is 100% active silicone polymer. No emulsifiers are present. Antifoam A Concentrate is typically effective at 1-100 ppm. Antifoam A Concentrate should be diluted with 3-10 parts of propylene glycol (aqueous) or vegetable oil (nonaqueous) with slow mixing. The product will be stable in the pH range of 5 to 9. Antifoam A Concentrate can be added directly to a fermentation medium, but it is not recommended that it be pumped to a fermenter on an as-needed basis.
Applicazioni
An extremely effective foam suppresser for use in aqueous and non-aqueous systems.
Antifoam A Concentrate has been used as a component of Luria Bertani culture medium for growth of BL21 (DE3) E. coli cells transformed with the plasmids. It has also been used as a constituent in the preparation of aerosol generation fluid.
Ricostituzione
1-50 ppm is adequate for most applications.
