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.
Description:
Coarse Porosity. 30ml. Disc Diameter: 30mm. Height Above Disc: 45mm. Stem O.D. 8mm. Stem Length: 75mm. Use when filter paper cannot withstand the attack of the filtrate. Heavy walled stem. Beaded top rim. Federal Specification DD-F-776.
Description:
Coarse Porosity. 350ml. Disc Diameter: 80mm. Height Above Disc: 75mm. Stem O.D. 20mm. Stem Length: 75mm. Use when filter paper cannot withstand the attack of the filtrate. Heavy walled stem. Beaded top rim. Federal Specification DD-F-776.
Description:
47mm Filtration Assembly With [standard taper] 40/35 Connection, With Stainless Steel Support. This unit is designed for filtering viscous or proteinaceous solutions or to produce an ultraclean filtrate.
Description:
Top I.D. 100mm. Stem O.D. 9mm. Stem Length: 97mm. Fits Paper Diameter: 185mm. Fast-filtering glass funnel. Design permits the filter paper to seal itself around the top. ASTM specification E1095, Type 1, Class A.
Description:
Medium Porosity. 2ml. Disc Diameter: 10mm. Height Above Disc: 30mm. Stem O.D. 7mm. Stem Length: 30mm. Use when filter paper cannot withstand the attack of the filtrate. Heavy walled stem. Beaded top rim. Federal Specification DD-F-776.
Description:
