CPF Polyethersulfone Membrane Capsule, 1.0 Micron Rating, CPEPS1-0, Electronic Grade, 4/Pack

EPS capsules are hydrophilic and manufactured with the highest quality asymmetric polyethersulfone membrane, double layered for extra security. PES membranes exhibit excellent flow rates with precise retention ratings. EPS capsules are used for critical applications in contamination control.

EPS capsule filters are used for final filtration of ultrapure DI water, low to moderate temperature final filtration of acids and bases, solvents, alcohols, copper plating solutions, photo resists and other liquids. Electronics grade PS capsules are most often applied for final filtration in tools at the point of dispensing.

Polyethersulfone has high flow rates and very low extractables and rinses to high purity very quickly. It is particularly suited for the filtration of water and aqueous solutions used in the production of the latest low nanometer geometry products.
