Overview
The CHROMAFIL Xtra GF/PTFE-20/25 combination filter is recommended for processing high particle load solutions or high viscosity solutions. This series of products adopts a composite structure of coarse glass fiber pre filter layer and small pore size polytetrafluoroethylene (PTFE) main filter membrane. The hydrophobic PTFE filter membrane has excellent solvent resistance and can withstand various organic solvents and strong acids and alkalis. The activation treatment of ethanol pre washing and water washing can make the originally hydrophobic filter membrane hydrophilic. The filter membrane is equipped with method validation and certification marks.
