Adapters, Distilling Trap, Kjeldahl
ChemglassAdapter is placed above flask to prevent carry-over of reactions which have a tendency to foam. With top standard taper outer and lower inner joints, both being the same size.
-
Side Seal Joints
ChemglassOuter joint having a tubulation sealed at the midpoint of the ground portion, and a corresponding hole drilled in the inner joint permitting venting of the side tube when the inner joint is turned to the proper position. Both of the 19/38 sizes are compatible with Buchi Rotary Evaporators. Part…

Adapters, Distilling Trap, Kjeldahl
ChemglassSimilar to CG-1032, but with joints of non-similar sizes at the upper and lower portion of the adapter. Dimensions are the same as the CG-1032.
-
Vapor tube/bump trap adapter is designed to be used with the Büchi® R-200/205 rotary evaporators. This adapter combines a vapor tube adapter and a bump trap. Trap has an extra coarse fritted disc sealed between the lower inner joint and the top flange. Adapters have a 50mm OD top flange…

Adapters, Moisture Test
ChemglassAdapter used to construct a simple moisture trap. Add a condenser to the top outer joint and a graduated funnel to the lower inner joint. Adapters with larger center to center spacing can be used with process reactors and larger flasks up to 50L.
-
Adapter has a coarse frit sealed between the #15 o-ring joint and the standard taper inner joint. Frit permits filtration of large particles before introduction into the flask and also serves as a bump trap for reactions being performed in flasks while connected to the manifold. Each adapter is…

Midget Bubblers, Graduated
ChemglassMicro impinger designed for sampling of small volumes of air at low jet velocity, as per EPA Method 6. Impinger bottle is graduated from 5 to 30mL in 5mL subdivisions. Both the bottle and stopper have 24/40 standard taper joints. The nozzle being replaced with an extra coarse fritted gas dispersion…
