Product Description
Reduce bumping and foaming carryover when distilling under vacuum or at small scale. A Claisen adapter adds a second neck to a single flask, so you can fit a thermometer and a capillary or addition line while vapor travels a longer, safer path.
This listing is for Kimble catalog number 274200-0000: KONTES Claisen Distillation Adapter. This adapter includes a side drip tip tube and a 10/18 thermometer joint, with all other joints at 14/20 standard taper. It is made from low extractable 33 expansion borosilicate glass.
