Product Description
Turn an open flanged reaction flask into a fully equipped reactor. A multi-neck top adds standard taper ports for a stirrer, condenser, addition funnel and thermometer, so you can configure the vessel exactly for the chemistry at hand. It is a flexible foundation for scale-up and process work.
This listing is for Kimble catalog number 296170-0000: KONTES Multi-Neck Reaction Flask Top, 19/22, 14/20. Tops have a ground flange that mates with 2 inch or 4 inch cylindrical and spherical reaction flasks and is held with a reaction flask clamp. Three and four neck versions are offered with center joints of 19/22, 24/40 or 29/42 and side joints of 14/20 or 24/40, some with a 10/18 or 10/30 thermometer joint. Glass is low extractable borosilicate. Add it to your LIGHT LABS order alongside the rest of your glassware and closures.
