Do you know the material ptfe ultrafiltration membrane? Do you know what it is used for? Let us uncover its mysterious veil together.
Ultrafiltration is a membrane separation technology, (UItrafil-tration referred to as UF).
Able to purify, separate or concentrate solutions.
Ultrafiltration is between microfiltration and nanofiltration, and there is no obvious dividing line between the three.
Generally speaking, the pore size of ultrafiltration membrane is between 0.05um-1nm, and the operating pressure is 0.1-0.5Mpa.
It is mainly used to intercept and remove macromolecular substances such as suspended solids, colloids, particles, bacteria and viruses in water.
Ultrafiltration membranes can be divided into organic membranes and inorganic membranes according to membrane materials.
According to the appearance of the membrane, it can be divided into: flat type, tubular type, capillary type, hollow fiber and porous type.
Currently, most household ultrafiltration water purifiers are based on hollow membranes.
PTFE ultrafiltration membrane has a minimum molecular weight cutoff of 500 Daltons and can be used to separate proteins, enzymes, nucleic acids, polysaccharides, polypeptides, antibiotics, viruses, etc. in biopharmaceuticals.
The advantages of ultrafiltration are that there is no phase transfer, no need to add any strong chemicals, it can be operated at low temperatures, the filtration rate is fast, and it is easy to perform aseptic processing.
All of these can simplify the separation operation and avoid the loss of activity and denaturation of biologically active substances.
