Duran - Filter Funnels
The glass filters are classified as being in porosity classes 0 to 5 according to their nominal maximum pore size. The following table shows the corresponding porosity range. The specified pore sizes always relate to the largest pore in the plate. This specification also characterises the minimum nominal size of particles which may be retained by the filtration.
