Distillation Tester

What It Is, How It Works, and Where It’s Used

Distillation Testers are laboratory instruments that determine the distillation range (initial boiling point, recovery curve, dry point, residue, and loss) of petroleum products and volatile organic liquids. By heating a precisely measured sample and condensing vapors under controlled conditions, a distillation tester reveals how a fluid separates into fractions across temperature—critical insight for quality control, product classification, and process optimization.

Qualitest offers Automatic Distillation Testers in single-station (standard) and Dual-unit configurations that conform to ASTM D86, ASTM D850, and ASTM D1078—the industry’s most referenced standards for atmospheric distillation testing.

Why Distillation Testing Matters

  • Product identity & compliance: Confirms products meet grade specifications (e.g., gasoline, jet fuel, kerosene, diesel, solvents).
  • Refining & blending control: Guides cut points and blending recipes to hit target volatility and performance.
  • Safety & performance: Ensures proper volatility for storage, transport, combustion efficiency, and emissions.
  • Incoming inspection: Validates supplier lots to reduce variability and prevent downstream issues.

Standards We Support

  • ASTM D86 – Atmospheric distillation of petroleum products and liquid fuels (e.g., gasoline, naphtha, jet fuel, kerosene, diesel, heating oils).
  • ASTM D850 – Distillation of industrial aromatic hydrocarbons and similar materials at atmospheric pressure.
  • ASTM D1078 – Distillation range of volatile organic liquids (e.g., solvents and oxygenated blends) at atmospheric pressure.

Qualitest Automatic Distillation Testers are engineered to deliver accurate, repeatable results across these methods with minimal operator intervention.
