0.22 um Filter

0.22 um filter uses imported medical-grade production equipment and a 100,000-level clean workshop. Each filter is tested for air tightness, and each batch of products is tested for integrity, chromatographic analysis, and ultraviolet absorption comparison. Strive for a 100% pass rate.

Compatibility and Material

0.22 μm filters are available in various materials such as cellulose, mixed cellulose esters, polyethersulfone (PES), polytetrafluoroethylene (PTFE), and nylon. The choice of material depends on compatibility with the filtered substance and the specific application requirements.

Pore Size

The pore size of 0.22 μm indicates that the filter membrane has pores with a diameter of 0.22 micrometers. This pore size is effective for filtering out bacteria, larger particles, and microorganisms from liquids. However, it is important to note that while 0.22 μm filters are effective in removing many microorganisms, they may not capture all viruses due to their smaller size.

Uses

PTFE is a relatively stable material, which can filter water, organic solutions, strong acids, and alkaline solutions (not suitable for trichloroethylene, gasoline, hexane, etc.). 0.22 um Filter can be used for experimental sample clarification filtration, liquid chromatography sample filtration, and so on. The filter is for one-time use, filtering about 10ml at a time (specifically depending on the impurities of the filtered liquid). The filter membrane cannot be disassembled.

Hawach provides a 0.22 um filter membrane for you to choose from, it can remove conventional impurities and bacteria invisible to the naked eye. Generally used in conjunction with the syringe.
