Hydrophilic PTFE Filter Cartridge
MLSTFL Hydrophilic filter cartridges are ideally suited for filtration of aggressive acids, bases & organic compound. The hydrophilic PTFE membrane has excellent chemical compatibility, wide-ranging thermal/PH resistance. These make the cartridge has a very good performance in chemical filtra-tion at aggressive environment. With no need to pre-wet or flush pre-wetting, these hydrophilic cartridges are able to maintain filtration integrity, allow optical clarity when wet, reduce interfer-ence with biological processes, and maximize shelf-life.
