Details

This convenient 250mL PYREX® bacteria-filtering assembly was designed by Dr. H.E. Morton of the University of Pennsylvania. It has an ultra-fine porosity (0.9 to 1.4µm) fritted disc that eliminates the need for rubber stoppers and the usual difficulties encountered when sterilizing rubber. Bacteria-free solutions are obtained as a result of these design features. The 10mm sidearm on the apparatus permits the insertion of a plug. A recess at the bottom of the outer ground joint also allows a plug. The unit will withstand the repeated autoclaving usually employed in laboratories. The unit is not designed for filtration sterilization of media and solutions. Autoclavable. Material: Borosilicate Glass Code 7740. Funnel Style: Filter. Disc Type: Fritted. Porosity: Ultra Fine (0.9 to 1.4µm). Height: 282mm (approximately). Disc Diameter: 40mm (approximately). Sidearm Length: 10mm. Capacity: 250mL. Corning® #: 33990-250.
