This is both an excellent and affordable kit for vacuum filtration.
A specialized funnel with a flat, perforated bottom (known as a Buchner Funnel) is used with a Vacuum Filtering Flask and Vacuum Pump. Suction from the pump forces the liquid to be filtered through the filter paper. This dramatically speeds up filtration of solutions that can take hours to filter on their own.
Included in the kit is:
one 500 ml Filtering Flaskone 90 mm porcelain Buchner Funnel100 sheets of 90 mm Filter Paperone specialized Rubber Stopper (to accept the large Buchner Funnel neck) a lab-quality hand operated Vacuum Pump with gauge.The kit comes packed in a box for easy storage.
