High-performance micro-porous structure

The micro-porous structure of the polysulfone filter is asymmetric as a whole and contains a dense layer. This structural characteristic with larger pore sizes both on the inlet and outlet sides has improved the filtration ability.

Excellent particle removal and retention performance

The dense layer and sharp pore size distribution inside the filter enable reliable retention and high-precision filtration of fine particles and micoorganisms.

Low initial pressure loss and a long service life

The high porosity rate of 80% characteristic asymmetric membrane structure, and large filtration area of the filter ensure a low initial pressure loss and a long filtration service life.

Quick resistivity recovery by the the least degree of flushing

The cartridge is made of carefully selected plastic materials for the highest effect of filter cleaning. The initial resistivity can be quickly recovered by flushing the filter to the least degree for a quick supply of ultrapure water.

Increased variety

With a new 0.1 μm size added to the 0.2 μm, 0.45 μm, and 1.2 μm lineup, the AstroPore PSE Cartridge W is now available in three pore sizes. The types available are G, M, P, and MP to meet specific needs in various fields.
