• Highly solvent resistant
• Low no-specific absorbing membrane for maximum protein recovery in critical analysis
• HPLC certification which guarantees the filter will not produce extraneous peaks in the UV range
• 100% integrity tested with higher burst strength ratings assuring they will perform as expected every time
• Available in 13, 25mm sizes so that you can pick the size that’s right for your application and minimize precious sample loss
• Wide range pore sizes 0.1um, 0.22um, 0.45um, 0.8um, 1.0um available, especially 0.45um for the most clarification applications and 0.2um when fine particulates removal is required


• HPLC samples containing low solid content
• Cell Culture samples filtration
• Sterile filtration of low volume samples
• Refravtometry
• UV/Vis samples
