Product Description
Filter under vacuum directly into jointed glassware without an adapter or a stopper that can leak. A sealed fritted disc, drip tip and built-in side hose connection make this a compact, all-in-one filtration unit for air-sensitive or small-scale work. It is a smart choice for inert-atmosphere and small-scale synthesis work.
This listing is for Kimble catalog number 954100-0123: KONTES Jointed Buchner Funnel, 40-60 µm, 145 mm, 20 mm. The funnel has a sealed-in fritted disc, a drip tip and an integral number 2 side hose connection. It is not recommended above 15 psi. Joints include 14/20, 24/40 and 29/42, capacities run from 15 to 600 mL, and porosities are coarse 40 to 60, medium 10 to 15 and fine 4 to 5.5 microns, all in low extractable borosilicate glass. LIGHT LABS supplies the complete DWK Life Sciences line, including Kimble, Wheaton and DURAN labware.
