Generally speaking, PTFE bubble point membrane has a fibrillar microporous structure. The porosity of this membrane can reach more than 88% or even higher, and there are 1.4 billion micropores per square centimeter. The pore diameter ranges from 0.1um to 0.5um.
Let’s find out today.
In chemical analysis, whether it is ion chromatography/gas chromatography or high-performance liquid chromatography, if the sample contains particulate matter, it will cause clogging of the chromatography column and greatly shorten the service life of the chromatography column; impurities in the sample It will also affect the accuracy of experimental results and waste a lot of time on repeated experiments.
I believe that you are smart and will not lose the big for the small.
Choose reasonable filters to get twice the result with half the effort.
Polytetrafluoroethylene bubble point film, also known as ptfe bubble point film, is generally made of polytetrafluoroethylene suspended powder as raw material, which is expanded and stretched to form a microporous film.
It has a fibrillar microporous structure, the porosity can reach more than 88%, there are 1.4 billion micropores per square centimeter, and the pore diameter ranges from 0.1μm to 0.5μm.
Generally, this film is coated on various fabrics and substrates using special processes to become a new filter material.
PTFE film manufacturer specializes in the production of polytetrafluoroethylene bubble point film. It has a full set of advanced production equipment and technology, and also has an advanced clean room and an independent composite slitting workshop to ensure the production quality of ptfe film; The product materials are all imported raw materials, with high uniformity, stable performance, good air permeability, and the filtration efficiency can reach 99.999995%! It can basically meet the filtration efficiency grade requirements of sub-high efficiency, high efficiency and ultra high efficiency filters.
