Q 7 . How can I choose the material of filter bags for pre-filter part of vapor sterilization (about 90ºC)？

Generally, the materials of filter bags are PP, PE and Nylon.
PE(hot resistance 100ºC) and Nylon(hot resistance 130ºC) are more suitable.
However, the loop has to used for stainless steel.
Besides, PP will be soften under 85ºC. PP is not suitable for high temperature filtration condition.
