Descripción general

Antifoam Y-30 Emulsion is an aqueous emulsion containing 30% active silicon. It contains non-ionic emulsifiers different from those in Antifoam Emulsions B and C. It is designed to control foam in aqueous systems.
Antifoam is also known as defoamer. It is a chemical additive that reduces and hinders the formation of foam in industrial process liquids. It is used to prevent formation of foam or is added to break foam that is already formed.

Aplicación

Antifoam Y-30 Emulsion is used for the following applications:
  • Chemostat cultivation.[1]
  • Cultivation conditions, such as Fed-batch fermentation.[2][3]
  • Bacterial strains and growth conditions (used in all aerosol experiments).[4]

Otras notas

Preguntas

1–7 de 7 Preguntas  

  1. Are Antifoam A (product number 10794) and Antifoam Y-30 (product number A5758) the same product? Can I use Antifoam Y-30 (product number A5758) as a replacement for Antifoam A (product number 10794)?

    1 respuesta

    1. The A5758, Antifoam Y-30, is a 30% solution containing non-ionic emulsifiers. It is prepared from an Antifoam A product that does not contain emulsifiers. The 10794, Antifoam A, is a deleted product, but was also a 30% solution containing emulsifiers. These products are from different brands, but functionally are identical and may be used interchangeably.

  2. How can Product No. A5758, Antifoam Y-30 Emulsion be used?

    1 respuesta

    1. This antifoam can be diluted with water. It is effective at low concentrations (1-100 ppm is the usual range to use). Trials can start at 50 ppm (active silicone), and amounts may be reduced to where the level of foam control is desired. The product should be agitated before use.
