ASTM D2892 (TBP)
True boiling point distillation of crude petroleum with a 15-theoretical-plate packed column and controlled reflux. Typically run to about 400°C atmospheric equivalent temperature (AET).
Laboratory crude oil distillation systems for ASTM D2892 true boiling point and ASTM D5236 vacuum pot still, plus mini and micro systems for small-sample crude assay. Turn-key, PC-controlled, made in the USA.

True boiling point distillation of crude petroleum with a 15-theoretical-plate packed column and controlled reflux. Typically run to about 400°C atmospheric equivalent temperature (AET).
Vacuum pot still method for heavy hydrocarbon mixtures. Extends the crude assay into the residue range after D2892, typically into the 370-565°C AET region.
Naphtha-cut distillation for organic chloride determination in crude oil. Precise fraction collection to 204°C (400°F).
When only milliliters of crude are available: mini (50-1000 ml) and micro (3-100 ml) systems distill from IBP to above 500°C on a single column.
Everything needed to perform a crude oil distillation in one package: column, vacuum, fraction collection, baths, and PC control. All you need is a sample and an operator.
Software guides the distillation from start to finish. Automatic vacuum control, fraction collection, AET calculation, and a permanent record of every run.
B/R offers expert support for crude oil distillation. A petroleum chemist is on staff who is a 30+ year member of ASTM.
