About Micro-Porous Filtration Membrane Application

Micro-porous filtration membrane

Categories:
There are mixed cellulose filter membrane, grid membrane, nitrate cellulose, acetate cellulose, nylon, and other filter membranes, as essential products in fine filtration process, whose pore size is from 0.15 to 5.0 microns.

Main Characteristics:
(1) Good hydrophilicity: Suitable for liquid filtration in condition from pH 3 to 10.
(2) High porosity: 70% – 80% with the pore size distributed evenly.
(3) Membrane thickness: 100-160um.
(4) Fast filtration speed, less adsorption, no medium shedded.
(5) Appearance: white, flat, smooth, without pinholes.

Filtration accuracy(um): 0.15, 0.22, 0.45, 0.65, 0.8, 1.2, 2.0, 5.0.

Filtration Membrane Application

Material Symbol Main Properties Application
Mixed cellulose filter membrane CA-CN

1 High porosity and good interception effect.

2 Intolerant to organic solutions, strong acid and strong alkali solutions.

3 High value-cost ratio.

1 In labs and small craft products, especially during removal filtration of bacteria and particle removal.

2 Detection OF coil-group in water

3 Filter membranes of two and five microns are also applied to oil filtration.

Grille Membrane

 

G/CA-CN

It is an ideal and accurate product of laboratories and quality supervision departments, also a super-clean blend membrane with printed grids for operators to easily count retentate amounts. It is usually applied to particle and bacteria detection as a composition of culture medium.
