Pore Sizes and Volumes. The filter size depends highly on the filtration volume. For small volumes (< 1 ml), syringe filters with a diameter of 3 mm are used for medium volumes (1-10 ml), 15 mm and for large volumes (> 10 ml) 25 mm. Common pore sizes for UHPLC and HPLC columns with small particle sizes (< 3 µm) are 0.2 and for columns with larger particle sizes (> 3.5 µm) 0.45 µm, respectively.

Understanding syringe filters – Andy Connelly

Sep 28, 2016· Some of the most common are cellulose acetate (CA) and polyethersulfone (PES). The key differences are chemical compatibility, flow rate, and burst pressure (i.e. strength). The material will also give variation in the effective filtration area (EFA) and therefore the capacity of the filter.

How to Choose a Merane Filter - Sterlitech Corporation

The pore size of a filter, stated in microns (aka micrometers or µm), is determined by the diameter of particles retained by the filter or by a bubble point test • Nominal ratings are the pore size at which a particle of defined size will be retained with an efficiency below 100% (typically 90-98%)

Merane Filters, High Performance Merane Filter

Labfil merane filters are available in PES (polyethersulfone), PTFE (Polytetrafluoroethylene) and CA (Cellulose Acetate). PES is an extra high performance merane formulated and optimised for critical fluid appliions. They have an asymmetric pore structure resulting in gradedparticle retention and therefore have excellent throughput.
