Faster flow rates than most sterilising-grade filters, reducing footprint
Ideal for buffers, other intermediate process fluids and cleaning solutions
Offer broad chemical compatibility, high flow rates and extended throughput

Merck Millipore, the Life Science business of Merck, today introduced Millipore Express® PHF (process protection, high-flux) hydrophilic filters for fast, efficient and economical buffer filtration.

The single layer, fast-flowing 0.2 µm PES membrane filters provide sterilising-grade performance and are ideal for buffers, pH adjusters and other process additives and intermediate fluids as well as cleaning fluids. The single-use, gamma ready filters are available in a fully scalable range of sizes from 25 mm to 76.2 cm cartridges.

The filters are designed to offer high-flux performance and improved process economics. Superior process efficiency and economy result from broad chemical compatibility, high flow rates and extended throughput.

Offering faster flow rates than most sterilising-grade filters, Millipore Express® filters allow users to accelerate their processes with the same size filter or reduce their process footprint, using a smaller filter.

Millipore Express® PHF filters are compatible with a wide range of buffer chemistries including acids and sodium hydroxide across the entire pH range. The filters can withstand multiple steam-in-place or autoclave sterilisation cycles.

“Improving process economics is always an imperative for our customers,” said Andrew Bulpin, Vice President, Process Solutions, Merck Millipore. “With a fast flowing membrane design, Millipore Express® PHF filters can be used to accelerate current processes or run the same process with a smaller filter footprint. And with a comprehensive range of sizes, these filters can support scale up and technology transfer with ease.”
