At one time, people thought that the smallest microorganism in the world was Serratia marcescens (minimum diameter of about 0.5μm). When syringe filter membrane When the pore size is small enough to completely intercept/filter Serratia marcescens, the pore size of the membrane/filter with this pore size is nominally 0.45 μm.
Later, people discovered Pseudomonas defectives (minimum diameter is about 0.3μm, now considered the smallest microorganism ), and the 0.45μm filter membrane cannot retain/filter out, so people further change the production process of the filter membrane. When the filter membrane can completely retain/filter out Pseudomonas deficiencies, people define the pore size as 0.22μm (That is, half of 0.45μm). Sometimes, for the convenience of use, it is said to be 0.2μm. Under the current technology, 0.22μm and 0.2μm are the same thing, and there is no one who is more precise.
PTFE membrane manufacturer specializes in the production of syringe filter membrane, with a full set of advanced production equipment and technology, as well as advanced clean rooms and The independent composite slitting workshop ensures the production quality of PTFE film; the product materials produced are all imported raw materials, with high uniformity, stable performance and good air permeability!
Needle filters using syringe filter membrane can well intercept harmful particles in the infusion liquid and inject them into the human body. The medicinal liquid is purified to reduce the potential or direct harm caused by particles to patients, thereby achieving the purpose of reliable treatment. We have a complete service system, with thoughtfulness before sales, attentiveness during sales, and peace of mind after sales! You are always welcome to come to the company for inspection or enter the store to consult with us.
