PES Pleated Filter Cartridge


Product Details

Product Description:

PES Cartridges are made up of Polyethersulfone with uniform pore distribution to ensure maximum performance in bacterial retentions. It’s upstream &downstream polyester support ensures complete resistance to pressure shocks. Polyethersulfone membrane is hydrophilic in nature, hence it allows easy integrity testing for all applications where daily controls are required. The membrane possesses broad chemical compatibilities & contains no surfactants. And it can provide absolut rating to fulfil the most demanding filtering requirements, widely used for sterile filtration in Active Pharmaceutical Ingredients production.
