The micropore separation process uses the size selectivity of the membrane to the separated components under the action of fluid pressure difference to trap particles and macromolecular solutes that can be retained by the membrane pores, while leaving particles or macromolecules that cannot be retained by the die pores. Small solute molecules pass through the membrane.
Teflon liquid filtration membrane operations include dead-end filtration (vertical flow filtration) and cross-flow filtration (tangential flow filtration).
Dead-end filtration is mainly used for fluids with small solid content and general processing scale. Most membranes are made disposable.
The commonly used filtration mobile phase and disposable syringe filter membrane for analysis is dead-end filtration.
It is a manufacturer of polytetrafluoroethylene (ptfe) membrane environmentally friendly materials that specializes in R&D, production and sales.
