Product Introduction
Alioth Membrane Filter is made from hydrophilic polyethersulfone (PES) membrane, and placed in a compatible membrane holder. It can remove particles and microorganisms from liquids, thus very suitable for the development and validation of early-stage filtration process. Besides, it can withstand multiple cycles of high-temperature and high-pressure sterilization, meeting the common requirements for liquid filtration in pharmaceutical industry.
