Product Description
Charge solid reactants into a jointed flask without dusting the neck or contaminating the joint. A powder funnel with a ground joint seats directly in the flask, so solids drop straight in and the joint stays clean for a good seal afterward.
This listing is for Kimble catalog number 629000-0023: KONTES Jointed Powder Addition Funnel, 29/42. These funnels are useful for adding reactants to a variety of flasks and are made from low extractable 33 expansion borosilicate glass meeting USP Type I and ASTM E438, Type I, Class A. They are offered with 14/20, 24/40 and 29/42 joints, with overall heights of about 68, 150 and 190 mm. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
