PES membrane filter
Product Description

Microlab PES membrane is a highly microporous membrane composed of modified polyethersulfone that is a tough, durable, and temperature-resistant aromatic polymer.
Microlab PES membrane provides high flow rate, low extractables and greater mechanical strength than competitive membranes. This membrane is specifically designed for biological, analytical, electronic, pharmaceutical, beverage, and sterilizing filtration applications.

•    Bacterial removal
•    Biosensors
•    HPLC flowing particle removal
•    Drug filtration
•    Organic solvents filtration    •    IV filters
•    Lateral flow assays
•    Particulate removal

Products Feature

A naturally hydrophilic membrane, Microlab PES Membrane does not require wetting agents that can interfere with biological processes. Additionally, its high surface area successfully immobilizes antigens, antibodies and other proteins. The resulting membrane has a void volume of 70-85 percent for high diffusion and low-flow resistance.
