Liquid Viscosity (Prefiltration)-Sterile Filtration
When selecting a filtration membrane, consider the fluid characteristics of your sample and the degree of filtration required. The more particulate-laden and/or the higher the protein concentration in a solution, the more difficult it is to filter. These types of liquids may clog filters prematurely, and multiple filters may be needed to process single batches, increasing the cost of filtration. The most efficient way to filter these solutions is to choose a filter with a built-in prefilter or a filter with more EFA. Pall Life Sciences can recommend an efficient filter for your toughest application needs. These include:
Built-in Prefilter Enhances Throughput of Viscous, Particulate-laden or Proteinaceous Solutions
Acrodisc and Acrodisc PF syringe filters with 0.2 µm Supor membrane were challenged with bovine serum or a bacterial culture (107 cfu/mL) at a constant pressure of 1.4 bar (140 kPa, 20 psi).
Pall also offers a variety of prefiltration and clarification devices optimized for non-critical or coarse filtration.
