Product Description
A chipped or broken funnel should not sideline an entire vacuum filtration setup. This 300 mL glass replacement funnel restores a 47 mm filter holder to full working order, giving a generous reservoir for membrane filtration of water samples, buffers and other liquids without frequent refilling.
This listing is for Wheaton catalog number 419350: 300 mL Glass Funnel for 47 mm Filtration Assembly. The funnel sits on a 47 mm support base and is held in place over the membrane with a clamp, forming a seal around the filter edge. Made from borosilicate glass, it resists chemical attack and can be cleaned and reused. Pair it with a fritted or stainless steel support base and clamp sized for 47 mm filters. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
