Antifoam defoamer

Japanese name: 消泡剤（アンチフォーム）

Antifoam agents, mostly silicone-based, suppress foam that forms in fermentation and cell culture, at low concentration. They prevent the oxygen transfer losses and filter blockage that foaming causes during bioreactor runs. Buyers choose by process: cell culture grades that spare cell growth and are animal-origin-free and sterile, silicone types for microbial fermentation, or organic non-silicone polyethers when silicone residue is a concern. Active concentration, sterilization form and effect on kLa matter too. The list below pairs each product with its maker and its Japanese sales channel.
