FAQs:

1. What is the difference between the membranes?
Nylon is good for aqueous solutions, PTFE is chemical resistant, PVDF has low protein binding, and wwPTFE combines PTFE's chemical resistance with hydrophilicity.

2. How do I choose between 0.2µm and 0.45µm filters?
Use 0.2µm for bacterial removal and 0.45µm for particulate filtration. Select based on the specific needs of your application.
