Organic Chemistry Deluxe Glassware Set, 26 Pieces

This Organic Chemistry Deluxe Glassware Set with standard taper ground glass joints is for distillation, extraction, synthesis, reactions, and other organic chemistry processes. The 24/29 standard taper ground joints fit together with nothing but glass in contact with the chemicals, so nothing contaminates the organic chemistry process. This set includes one each 100 ml, 250 ml, and 1000 ml round bottom flasks, a 500 ml two-neck distilling flask, a 500 ml three-neck distilling flask, a 300 mm Graham condenser, a 300 mm distilling cylinder, a 250 ml separatory funnel, a Claisen adapter, a 75° distilling head, a 105° vacuum receiving tube, a thermometer jacket tube, four glass stoppers, and 10 plastic joint clips. The 26-piece glassware set allows various organic chemistry process configurations. The high-quality GG17 borosilicate glass components, with a low coefficient of thermal expansion, will withstand typical laboratory thermal variations common to chemistry processes like heating and cooling. Standard taper ground joint glassware is commonly used for organic chemistry. 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. The standard taper ground glass joints are the 24/29 international standard, which means 24 mm in diameter at the widest part of the joint with a standard taper and 29 mm length. These pieces also fit together with 24/40 ground joints, which are the US standard: still 24 mm in diameter with a standard taper, but 40 mm in length. You provide support stands and clamps, a burner, thermometer and stopper, and condenser tubing to complete your distillation set-up.
