Whatman polyamide membranes are made from pure polyamide making them the universal filter for clarification and sterile filtration.
Polyamide membrane filters are mechanically very strong and exhibit excellent wet strength and dry strength. They are hydrophilic making them suitable for aqueous and organic solutions. The membrane filters can be used up to 135º C.
