This vacuum distillation set is made from Borosilicate 3.3 glass and includes five pieces: a 250 ml round-bottom flask, a still head, a Liebig condenser, a vacuum receiver adapter, and a 100 ml Erlenmeyer flask. All joint sizes are 24/29. Vacuum distillation allows for the separation of compounds at lower temperatures than atmospheric distillation, which is useful for heat-sensitive materials. The borosilicate glass construction provides chemical durability and thermal resistance suitable for reduced-pressure distillation procedures.
