NOH® Membrane Filters

N.O.H International

Introduction

Membrane filters or "membranes" are microporous films with specific pore size ratings. Membranes retain particles and microorganisms that exceed their pore ratings by acting as a physical barrier and capturing such particles on the surface of the membrane.
N.O.H International offers membrane discs in diameters from 13mm to 293mm and materials including PES , MCE, Nylon, PVDF , PTFE , PP , CA, PP Mesh, Nylon Mesh, PC and RC which are manufactured in ISO 9001 certified facilities.
N.O.H International' Chemical Compatibility Chart will help you choose the right type of membrane for your application.

Features

High Porosity: N.O.H International’thin membrane with high porosity provide high liquid and gas flow per unit area. High porosity also provides high surface area for adsorption or binding
Diversity: N.O.H International Supply carries many different types of membrane filter which you can easily find your applica tion in one of our membranes.
Clean: As part of comprehensive quality program, only high purity raw materials and reagents are used to produce N.O.H International membranes.
Strong: N.O.H International’membranes are monitored for both burst and tensile strength. PTFE and Nylon are very strong for most aggressive applications.
