Syringe filters Puradisc™ FP30, CA

Syringe filters are suitable for rapid sample filtration and are used in a variety of applications, such as capillary electrophoresis, protein filtration, and UV spectroscopy sample preparation. With female Luer lock inlet.For the ready-to-use filter units, only virgin raw material is used. This ensures that there is no interaction with the sample to be filtered, provided that the units are used properly. The filter units are intended for laboratory use only.Note: If syringes with a volume <10 ml are used, a pressure could be created which exceeds the max. operating pressure (700 kPa/7 bar) of the filter unit.Hydrophilic membrane made of cellulose acetate (CA). Very low protein binding capacity.Housing made of PCOutlet male Luer coneAutoclavable at 121 °C
