Review on StonyLab Glass Vacuum Adapter: 105° Bent, Short Stem With 24/40 Joints For Effective Take-Off by Christopher Kanter

The quality of this piece of glassware is good and the angle is spot on at 105 degrees. The only problem I have with it is that the outer joint does not accept a 14/20 Keck clip. All of my other 14/20 glassware easily accepts the clips and after comparing the outer joint with my other glassware the outside diameter of the outer joint is noticeably larger. The actual joint itself is fine and provides an air tight connection. This was a serious problem for my setup and forced me to improvise a solution.
