Product Description
Know exactly how much reagent you have added at every point in a reaction. A double scale reads both up and down, so you can track volume added or volume remaining at a glance, and the PTFE stopcock delivers smooth, grease-free control throughout the addition.
This listing is for Kimble catalog number 29040F-500: KONTES Graduated Addition Funnel With PTFE Stopcock, 500 mL. The funnel carries a double white ceramic enamel scale, with the right side ascending and the left side descending, and is calibrated to contain. A pennyhead glass stopper is supplied. Designed from ASTM E1096, Type 1C, it is made from low extractable 33 expansion borosilicate glass in 125, 250, 500 and 1000 mL capacities. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
