This Vacuum Distillation Glassware Kit for organic chemistry has standard taper ground joints supports regular or vacuum distillations. The 24/29 standard taper ground joints means the different pieces fit together with only glass in contact with the chemical solutions and distillation process. This means nothing contaminates the distillate produced. This kit includes a 500 ml round bottom flask, a 1000 ml round bottom flask, a 300 mm Graham condenser, a 75° distilling head, a 105° vacuum receiving tube, a thermometer jacket tube, a glass stopper, and five plastic joint clips. Does NOT include a thermomter.
The glass components are all made from high-quality GG17 borosilicate glass that has a very low coefficient of thermal expansion. This means the glassware is capable of withstanding typical laboratory thermal variations common to chemistry processes like heating and cooling. Standard taper ground joint glassware is commonly used for organic chemistry processes. Just a thin film of silicone grease or a layer of PTFE tape on the joint creates a leak-proof connection, even under vacuum or modest pressure. The plastic joint clips hold the connections tightly together.
These standard taper ground glass joints are the 24/29 international standard, which means 24 mm diameter at the widest part of the joint with a standard taper that is 29 mm long. These pieces also fit 24/40 ground joints, which are a US standard, having the same 24 mm diameter and standard taper but 40 mm length. You provide support stands and clamps, a burner, thermometer and stopper, and condenser tubing to complete your distillation set-up.
