The heart of Pall Life Sciences is the manufacture of membrane filters. From the polymer used to the final pore size, it is the membrane that determines a filter's effectiveness. A filtration membrane is a thin, polymeric film made up of thousands of microscopic pores. The size of these pores determines the size rating of the membrane. Membranes can be used in the quantitative separation or filtration of suspended matter from liquids and gases.
Membranes have many different properties which affect the performance of the filter in applications.
These properties are discussed in detail in our Basic Filtration Concepts section . Pall Life Sciences offers an extremely broad range of membranes for scientific research and testing for Life Sciences, Analytical Chemistry, Microbiological Analysis, and Environmental Sampling. This section lists specifications for the entire range of membrane filters offered by Pall Life Sciences.
