Heavy duty filtration funnels assist in collecting solid compounds present in liquids. Poured liquids travel by vacuum suction through fritted discs or perforated plates to flow out the long, angled stems. Common Hirsh or Buchner styles with ribs prevent airlock and make operation faster. The chemical and temperature resistance permits fluted filtration funnels to accommodate harsh materials and repetitive sterilizing procedures. Models vary in capacity, porosity, and filter paper accommodating sizes.
