33990-250 PYREX 250mL Morton Bacteria Vacuum Filter System w

Corning Designed by Dr. H.E. Morton of the University of Pennsylvania, this convenient 250mL PYREX® bacteria-filtering assembly 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 the following 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. -These units are not designed for filtration sterilization of media and solutions.
