Opis

Opis ogólny

Antifoam A is a silicone-based product used to prevent or minimize foaming in both microbial fermentation systems and mammalian suspension cultures. Control of foaming minimizes damage to the cells, resulting in increased protein/antibody production. Extremely effective for aqueous and non-aqueous systems. Effective at concentrations in the 1-50ppm range.

Zastosowanie

Antifoam A concentrate has been used:

• in bioreactor culture for Staphylococcal enterotoxin C (SEC) production.
• to prevent foam formation during the aerobic treatment of sludge.
• to study the impact of surface tension on bioaerosol generation during bubbling.

Cechy i korzyści

• Molecular biology grade and tested for use in bacterial fermentation.
• Extremely effective foam suppressor for aqueous and non-aqueous systems.
• Made of 100% active silicone polymer, free of emulsifiers.
• Typically, effective at 1-100 ppm.
• Product will be stable in the pH range of 5 to 9.
• Can be directly added to a fermentation medium but it is not recommended that it be pumped to a fermenter on an as-needed basis.

Komponenty

Antifoam A is a 100% active silicon polymer containing no non-ionic emulsifiers .

Uwaga dotycząca przygotowania

Antifoam A can be pre-diluted with 3-10 parts of aqueous propylene glycol or non-aqueous vegetable oil with slow mixing.
