of filter units that is. :D

Ok so it seems everyone likes PVDF membranes but on a certain website I see some bottle tops that have a PES, PVTF, CES etc. Is PVDF absolutely necessary when using bottle tops?

This is from a website with PES membrane: Thermo Scientific* Nalgene Rapid-Flow sterile disposable bottle top filters with PES (polyethersulfone) membrane provide the last line of defense against cell culture contamination.
Low protein binding PES membranes with low extractables are the best choice for sterile filtration of cell culture media, serum, additives and buffers. Asymmetric PES membranes and exclusive Rapid-Flow support plate design provide fast flow rates and high throughput for increased filtration efficiency.
