Heavy Duty Borosilicate Glass Filter Funnel

The Eisco Labs Heavy Filter Funnel is constructed from high-quality borosilicate 3.3 glass with thick, uniform walls for greater mechanical strength and longer service life under heavy use. The 60° angle and 8mm-diameter plain stem support continuous, even flow of liquid during filtration. Funnel measures 76mm (3") in diameter and 5.5" in total length. Stem length is 2.75", with a 4mm inner diameter and 8mm outer diameter. Filter paper is required (sold separately) and the funnel accommodates a range of standard paper sizes for routine laboratory filtration.
