EMD Millipore, the Life Science business of Merck KGaA of Darmstadt, Germany, 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 sterilizing-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 30 inch 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 sterilizing-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 sterilization cycles.

“Improving process economics is always an imperative for our customers,” said Andrew Bulpin, Vice President, Process Solutions, EMD 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.”
