一般說明

消泡剂Y-30乳液是含有30%活性硅的水性乳液。它含有的非离子乳化剂与消泡乳液B和C不同。它专用于控制含水体系中的泡沫。
消泡剂又称为去沫剂。它是一种化学添加剂,可减少和阻碍工业过程液体中泡沫的形成。它被用于防止形成泡沫或破坏已经形成的泡沫。

應用

消泡剂Y-30乳液适用于以下应用:
  • 恒化培养。[1]
  • 培养条件,如补料分批发酵。[2][3]
  • (所有气溶胶实验采用的)细菌菌株和生长条件。[4]

其他說明

消泡剂A浓缩液的30%水乳液。

聯結

在含水体系中的分散性比消泡剂A浓缩液更好。

The synthesis and assembly of the active site [FeFe] unit of [FeFe]-hydrogenases require at least three maturases. The radical S-adenosyl-l-methionine HydG, the best characterized of these proteins, is responsible for the synthesis of the hydrogenase CO and CN(-) ligands from

A murine low dose (LD) aerosol model is commonly used to test tuberculosis vaccines. Doses of 50-400 CFU (24h lung CFU) infect 100% of exposed mice. The LD model measures progression from infection to disease based on organ CFU at

Questions

1–7 of 7 Questions  
  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 answer
    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 answer
    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.
