Laboratory distillation since 1966
B/R fractional distillation systems separate close-boiling materials with spinning band and packed column technology—from micro samples to production-scale boilers.
Glass and stainless steel fractional distillation apparatus for research, QC, and production environments.
Simple distillation collects everything that vaporizes once. Fractional distillation returns part of that vapor as reflux so the mixture is distilled again and again—each step raising purity.
Lower-boiling components enrich in the vapor phase above the boiling flask.
Spinning band or packing maximizes vapor–liquid contact inside the column.
Controlled reflux ratio delivers successive “steps” of separation at the condenser.
Vapor–liquid diagram: each equilibrium step moves composition toward higher purity.
From petroleum labs to fragrance houses, B/R systems handle close-boiling and high-purity work.
