Millipore boosts availability of PES filter

SEPT. 4–BILLERICA, Mass.–Millipore has announced the availability of its high flux sterilizing-grade polyethersulfone (PES) filter for the filtration of buffers, pH adjusters and other clean aqueous intermediate process solutions.

Millipore Express SHF (Sterilizing-grade High Flux) hydrophilic 0.2 µm filters provide superior flux, high sterility assurance and broad chemical compatibility with a wide range of buffer chemistries (pH 1- 14), including acids and sodium hydroxide (NaOH). The patented asymmetric composite membrane delivers high permeability and flow rates up to two times faster than competitive sterilizing-grade filters.

Improving process efficiency by up to 50 percent, the Millipore Express SHF filters allow biopharmaceutical manufacturers to either reduce filtration area while maintaining the same batch volume; or double output capacity without increasing filtration area requirements.

Millipore Express SHF filters are available in a variety of formats to meet customer needs from process development to full-scale manufacturing.
