Sloping Claisen Head with Two B14 Sockets, 19/26 Flask and 19/26 Condenser Cones, Borosilicate Glass

This sloping Claisen head is made from borosilicate glass with two B14 socket joints on the upper arms and a 19/26 cone joint at the base. A second 19/26 socket joint connects to a condenser. The sloping design directs distillate toward the condenser arm while the second neck accommodates a thermometer, addition funnel, or stopper. This adapter converts a single-neck flask into a two-neck configuration for distillation, reflux, and fractional distillation setups.
