Millipore expands line of hydrophilic PTFE membranes

Millipore announced today the availability of their Omnipore™ membrane filters, which joins the LCR membrane to complete their offering of hydrophilic PTFE membranes.

Omnipore membrane is compatible with virtually all solvents, acids, and alkaline solutions. Omnipore membrane filters are available as 13 mm, 25 mm, and 47 mm cut disks in a range of pore sizes from 0.1–10 µm. The LCR membrane is specifically manufactured for HPLC solvent filtration applications.

Hydrophilic PTFE membrane is optimized for low drug and protein binding with excellent throughput in typical aqueous and solvent sample preparation. High sample recoveries and low extractables provide for optimum analysis by HPLC and LC/MS/MS. The membrane is suitable for applications including natural product screening, aqueous solubility testing and total drug analysis.

Millipore also offers a full line of hydrophobic PTFE membranes, both supported (Fluoropore™ membrane) and unsupported (Mitex™ membrane). For the broadest chemical resistance, hydrophobic PTFE membrane is recommended. Designed for extended sample incubation times and the lowest extractables, hydrophobic PTFE membrane is ideal for NCE cleavage and cleanup. It is also suitable for in-plate protein precipitation and sample recovery following in-plate compound cleavage from solids or beads.
