The primary concern when choosing a solvent filter is solvent compatibility with the filter material. Pall offers several filters to accommodate the various types of HPLC solvents. Pall’s wwPTFE membrane that is chemically compatible with the majority of common mobile phase solutions and solvents, thus eliminating confusion with filter selection.
To ensure you always have the most accurate information for using Millipore ® products, we have compiled several published solubility and compatibility tables to provide a comprehensive compatibility guide for Millipore ® membranes, filtration devices, ultrafiltration products, centrifugal filters, and MultiScreen ® filter plates. All information presented below is based entirely upon published polymer and metal compatibility tables, not from usage experiments conducted by our scientists.

Filter Membranes. Produced by the precipitation or stretching of polymeric materials, membrane filters are commonly used in both industry and research. Properties of membrane filters vary widely with differences in composition, surface treatments, and pore size. Selecting the ideal filter requires an understanding of basic characteristics.
1) Syringe filter housings are manufactured from solvent-resistant, low-extractable polypropylene resins specifically selected for wide compatibility with common HPLC sample matrices. 2) Solutions at temperatures up to 100°C can be filtered using syringe filters. 3) Syringe filters can be sterilized by autoclave at 125°C for 15 minutes.
Note: Extractable levels may be reduced by flushing the filter prior to use.

Depth filtration. In terms of particle retention, filters fall into two categories: surface filters and depth filters. Surface filters, generally referred to as membranes, trap particles exclusively on the top surface. These filters are well suited to samples with low particulate content. However, high particulate content tends to rapidly clog
relate to a membrane that may respond almost immediately to immersion in solvent. In addition, solvent-membrane compatibility requires additional consideration of filtration-specific factors. None of these published compatibility guides, for example, monitors the solvent’s ability to wet a membrane or increase extractables. 4.

Membrane filters Unlike cellulose and glass microfiber depth filters, membrane filters are conventionally classified as surface filters because the filter matrix acts as a screen and retains particulates almost entirely on the smooth membrane surface. The retention levels for these filters extend down to 0.02 µm and allow the efficient retention
