Description
Membrane filtration offer a very convenient, fast and economical separation method.
They offer below mentioned advantages;
- Large load carry capacity
- High permeability to air
- They offer below mentioned advantages
- Non-hygroscopic and biologically inert
- Chemical resistance to most solvents and reagents.
- Very high temperature resistance
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 atmosphere 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.
PTFE: 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, aerosol 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 hydrophobic and can be used for hot gases up to 180°C.
GF/C: glass fibre filter
Suitable for determination of liquid scintillation counting and total suspended solids collection in potable water and in industrial waste. Grade 50C glass fibre filters are hydrophilic and medium / fast, very high loading. They resist temperatures up to 500°C.
