Crude Oil Distillation Equipment
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.
01
Lab-Scale Crude Oil Distillation Methods
ASTM D5236 (Pot Still)
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.
ASTM D4929
Naphtha-cut distillation for organic chloride determination in crude oil. Precise fraction collection to 204°C (400°F).
Mini and Micro
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.

Questions
Crude Oil Distillation FAQ
What is laboratory crude oil distillation?
Lab-scale crude oil distillation separates crude into boiling-range fractions that model refinery yields. It provides true boiling point data for assay, quality control, purchase decisions, and refining models. See why labs distill crude on a lab scale.
What is the difference between ASTM D2892 and D5236?
ASTM D2892 is true boiling point distillation with a 15-plate packed column and reflux (typically to ~400°C AET). ASTM D5236 is the vacuum pot still method that continues the assay into heavy fractions. Many labs run both on complementary B/R systems. Read more on D2892 TBP and D5236 pot still.
What sample sizes are available?
How does this relate to ASTM D1160?
ASTM D1160 is vacuum distillation of petroleum products (heavy oils, residuals, biodiesel) at reduced pressure, not full crude TBP assay. For D1160 boiling-range work, see our ASTM D1160 vacuum distillation apparatus.
