Millipore Corporation announces the availability of 33-mm Millex syringe filters with nylon membrane in 0.20-m and 0.45-m pore sizes for analytical sample preparation. The non-sterile syringe filters are used for 10 to 100 mL of aqueous and mild organic solution filtration prior to high performance liquid chromatography (HPLC) or other instrument analysis. The color-coded, over-molded design results in a high operating pressure of 100 psig (10 bar) and delivers faster filter rates for high throughput. http://www.millipore.com
