A membrane filter that does not use any adhesives or surfactants, resulting in extremely low leaching!
The "LPFPE series" is a filter that uses a high-precision PTFE membrane for the filtration medium and HDPE for the structural components, providing excellent chemical resistance to organic solvents. Since it does not use any adhesives or surfactants, the leaching is extremely low, making it suitable for filtering high-purity chemicals such as photoresists, resist raw materials, developing solutions, and etching solutions. It is particularly effective at filtering gel-like foreign substances in resists. 【Features】 ■ Uses a high-precision PTFE membrane for the filtration medium and HDPE for the structural components ■ Excellent chemical resistance to organic solvents ■ Suitable for filtering high-purity chemicals ■ Particularly effective at filtering gel-like foreign substances in resists ■ Completeness tests are conducted on all products before shipment *For more details, please refer to the PDF materials or feel free to contact us.
