Filtration System

Membranes are important components of filtration systems. They are microporous plastic films with specific
pore size ratings, and retain particles or microorganisms larger than their poresize primarily by surface
capture. All of them are made of medical grade materials, available in five kinds of membranes with 0.22µm
(sterilizing grade) or 0.45µm (clarification grade), sterilized by gamma, RNase-free, DNase-free and
non-pyrogenic.

Vacuum Filtration System

Designed for vacuum filtration of different solutions

● Gamma sterile, RNase-free, DNase-free and Non-pyrogenic

● Four types of membranes include PVDF, PES, MCE and NYLON optional
