4-Piece Fractional Distillation Set with 250mL Flask and Vigreux Column, 24/29 Joints, Borosilicate Glass

This fractional distillation set is made from Borosilicate 3.3 glass and includes five pieces: a 250 ml round-bottom flask, a Vigreux column, a still head, a second still head, and a receiver adapter. All joint sizes are 19/26. Fractional distillation is used to separate a mixture into its individual components by heating. The Vigreux column provides additional surface area for vapor condensation and re-evaporation, improving separation efficiency compared to simple distillation. The borosilicate glass construction provides chemical durability and thermal resistance suitable for standard distillation procedures.
