The "Universal" Membrane Filter for All of Your Analytical Filtration Requirements
 - Acrodisc PSF syringe filters are Zymark* and SOTAX* Automation Certified to ensure smooth

    operation and worry-free performance 24 hours a day in automated workstations. 
 - Avoid the expense and inconvenience of keeping a variety of filters on hand. Versatile filter for

    aqueous and aggressive organic solvent-based solutions. 
 - Low protein binding membrane gives high recovery of critical proteinaceous samples. 
 - Accurate analysis. HPLC certified for low levels of UV-absorbing extractables. 
 - Easy filtration of particulate-laden samples with glass fiber prefilter version. 
 - 13 mm Acrodisc syringe filter with minispike configuration offers low hold-up and easy filtration into autosampler vials. 
 - Protects columns and instrumentation from particulate buildup better than other filters
