General Description of Water/Liquid Prefiltration:
A nanofiber membrane disk is a special type of filtration medium,
characterized by its structure composed of numerous tiny
nanofibers. These fibers typically have diameters on the nanoscale,
ranging from 1 to 100 nanometers. The fabrication of such a
membrane disk usually involves electrospinning technology, a
process that involves the extrusion of polymer solutions or melts
through a high-pressure nozzle, followed by the formation of fine
fibers through the action of an electric field.
Application of Water/Liquid Prefiltration:
1.Common efficient filtration, such as pharmaceutical solutions,
buffers, media
2.Remove or trap fine precipitates and suspended solids from the
sample
3.Purification of aqueous and organic solutions
4.Biological sample preparation
5.Sample preparation for environmental analysis
Features and Benefits of Water/Liquid Prefiltration:
* Possesses high efficiency in adsorption and interception;
* Effectively removes fine particles, bacteria, viruses, etc., and
can even achieve filtration precision down to the nanoscale;
* Has good biocompatibility to avoid adverse effects on biological
organisms;
* Strict quality control system, complete production process flow;
* Short delivery period;
* Flexible payment method: T/T, L/C, West Union, Paypal;
* Free technical support;
* Other specific sizes can be customized;
