Mini High Efficiency Fractional Distillation

by B/R Instrument

Purifying Flavors, Fragrances, Natural Products, and Essential Oils (25 ml to 1 liter)

The 36-100 fractional distillation system is ideal for purifying flavors, fragrances, natural products and essential oils in the 25ml to 1 liter range.

Key features include:
High purity

The 200 theoretical plate fractional distillation column can product high purity distillates. For flavors, fragrances, natural products and essential oils, even small increases in purity can translate to large increases in value.

Low pressure drop

The spinning band distillation column has virtually no pressure drop from the top to the bottom compared to a packed column. This can be a big advantage when distilling delicate samples that decompose easily when heated too high.

Low "hold up"

The spinning band distillation column has less than 1.5 milliliters remaining behind in the column after the distillation is complete. This means that the smallest amount of valuable material possible is lost in the purification process.


The 36-100 fractional distillation system can be fully automated. Once the desired parameters are programmed, the distillation proceeds without any operator intervention, freeing up valuable operator time to perform other important work.

The 36-100 spinning band fractional distillation system features:
  • All Glass and Teflon Components
  • 200 Theoretical Plates Distillation Column (maximum at atmosphere)
  • 25ml to 1 liter boiler capacities
  • Automatic and Manually Operated Distillation Systems
Column Length Diameter Plates Flask Sizes
36-100 Spinning Band 90 cm 8 mm 200 (Teflon Band) 50, 100, 250, 500 and 1000 milliliters
Automation and Accessories

All our distillation equipment is available in fully automatic or manually operated models. Manually operated distillation systems are inexpensive and simple to operate. Automatic models are microprocessor controlled. All the distillation functions are fully automated to make the distillation process easy and efficient from beginning to end.

Automatic Controller (Optional PC Interface)

The automatic controller minimizes the amount of operator time required for each distillation. Select your stored distillation program and let the controller perform the distillation. Collect up to 8 fractions. Each fraction has programmable:

  • Open Temperature
  • Close Temperature
  • Heat Rate
  • Reflux Ratio
  • Programmable shut down at end of distillation

Each distillation program has a programmable:

  • Vacuum level
  • Maximum Boiler temperature (safety feature)
  • Equilibration Time

The controller allows easy editing of parameters while the distillation is in progress. Or run the distillation from a PC.

VAC-1000 Vacuum Regulation System

Materials that have very high boiling points or are subject to thermal degradation should be distilled at reduced pressures. The VAC-1000 is a complete, stand alone vacuum system that can provide regulated vacuum to any distillation system. It features a 5 decade pressure sensor, proportional control valve, vacuum manifold/trap, 2 stage mechanical pump, all mounted on a roll around cart for easy maneuverability in the laboratory. The VAC-1000 can be used with automated or manually operated columns.

Automatic and Manually Operated Fraction Collectors

Four and eight place fraction collectors are available to direct distilled material to the desired receiver. Automated versions allow distilled fractions to be collected unattended. Manually operated versions are also available. Various size receivers are available in glass, stainless steel and plastic.
