Millipore® AP20 Glass Fiber Filters and Prefilters, 2µm

Millipore® AP20 glass fiber filters are widely used as prefilter for 0.8 to 8.0µm glass fiber filters. They are often used as a prefilter in applications using them upstream to protect type AP15 glass fiber filters in serial filtration. Millipore® AP20 glass fiber filters have lower retention and higher dirt-holding capacity than AP15 glass fiber filters.

Millipore AP20 glass microfiber filters with binder resin have superior wet strength and are excellent for qualitative analysis and prefiltration, especially for heavily contaminated liquids. Glass microfiber filters with binder resin are also widely used for clarification of aqueous solutions. Glass fiber filters can be sterilized by EO, gamma irradiation, or autoclaving at 121°C at 1bar. Pore Size: 2.0µm; Thickness: 380µm. Water Flow Rate: 1.3mL/Minute x cm2; Porosity: 90%; Protein Binding: 60µg/cm2.
