Millipore has introduced Omnipore membrane filters, which join the LCR membrane to complete the company’s 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.
