Filtration Water for Patient Care - Membrane Solutions
This membrane is incorporated in other filters from Membrane Solutions Corporation for use in the pharmaceutical industry, where it has met the standards for sterilizing filtration of parenteral solutions. Contamination of the water supply with potentially pathogenic organisms is common.
Choosing the Best Syringe Filters for Biological Sample
Captiva Premium PES syringe filter versus PVDF syringe filters PVDF membranes have been claimed to feature low protein binding, and thus they have been widely used for filtering biological samples targeted to protein and peptide analysis. Four types of PVDF syringe filters from different suppliers were thus selected for comparison.
Syringe Filter Efficiency on HPLC Column Life - Membrane
Using Membrane Solutions syringe filters with GHP (hydrophilic polypropylene) membrane is the most efficient way to remove particulate and prolong the life of HPLC system components. Membrane Solutions’ syringe filters with GHP membrane are widely used for this purpose. The average retention efficiency of 0.45 µm rated syringe filters with

Understanding syringe filters – Andy Connelly
Sep 28, 2016 · Other, filter holder (in-line) types allow you to regain your filter (Figure 1). Syringe filters normally use membrane type filters which have a specific particle size cut off (e.g. 0.45 μm). Syringe filters are also available for the filtration of gases and for the removal of bacteria from a sample.
