MEMBRANE FILTERS

Membrane filtration offer a very convenient, fast and economical separation method.

They offer below mentioned advantages;

Excellent level of particle retention
Large load carry capacity
High permeability to air
Non-hygroscopic and biologically inert
Chemical resistance to most solvents and reagents.
Very high temperature resistance

Available 2 products:

filters with 0,45 μm pore size
filters with 0,20 μm pore size

CM: cellulose mixed ester membrane

Particularly suitable for aqueous solutions. They are hydrophilic. Thermally stable to 121°C. Ideal for gravimetric analysis and are often used for contamination tests.

NC: nitrocellulose membranes

They are easily wettable and suited for filtration of aqueous solutions. In dry athmosphere these membranes are thermally stable at 125°C and can be autoclaved at 121°C. RC: regenerated cellulose membranes These membranes are resistant to most organic solvents. They are mostly used for filtration of solvent mixtures and ultra-purification and degassing of HPLC eluents.

TE: polytetrafluoroethylene membranes

Particularly suitable with aggressive media, as well as to concentrated acids and bases. They are hydrophobic, they can be used up to 145°C.

PE: polyester membranes

They are hydrophilic. Particularly suitable for fine titration, dust analysis, aerrosol analysis and ultra-purification of solvents.

CA: cellulose acetate membranes

They have a low protein binding capacity and they are suited for aqueous and alcoholic media. They are hydrophibic and can be used for hot gases up to 180°C.
