Sterilizing-Grade PES Membranes Capsule Filters

Short Description:

Puno PES capsule filters is family of full size capsule filters

with various ways of connection at the vent, which enables in-line integrity test.

The PES membrane bio-burden reduction capsule utilizes single layer hydrophilic

polyethersulfone membrane. It offers broad chemical compatibility,

high flow rate and low extractables

Polyethersulfone is particularly suited for the filtration of products that

contain substances that adsorb to the media The lower binding characteristics

of polvethersulfone make it a good choice for filtration of valuable

protein solutions such as vaccines and biologicals
