Overview
Benefits

Flexible and efficient

  • Soxhlet, Soxhlet Warm, Hot Extraction and Continuous Flow on the same instrument
  • Combine the benefits of Soxhlet and Randall extraction in one instrument
  • Reach the required detection limit thanks to 60% larger sample volume (LSV configuration)
  • Compatible with many solvents and samples

Reliable

  • Contamination free instrument thanks to autoclavable parts
  • No alternating blank values thanks to elimination of residual effects
  • Better recoveries by drying under inert gas

Safe and compliant

  • Perfect observation of the process thanks to visible glass setup
  • Minimized solvent loss thanks to high performance condenser
  • Risk of burns reduced by effective shielding and heating control
  • Full compliance achieved using the Soxhlet mode
Features
Compliant Soxhlet extraction

Compliant Soxhlet extraction

Soxhlet extraction in full compliance with official methods for environmental applications or for fat determination in food and feed samples.

Optimized sample size

Optimized sample size

The B-811 LSV with the larger sample volume allows for higher quantities to reach the required detection limit of the analyte. The main glass parts are expanded up to 60 %.

Sample level adjustment

Sample level adjustment

Easy adjustment of the level detection sensor 1 to the sample volume for increased throughput and efficiency of the Soxhlet cycle.

Wide application spectrum

Wide application spectrum

Use high-boiling solvents of up to 150 °C thanks to two built-in heating sources per extraction location and optimal heat transfer.

Working under fully inert conditions

Working under fully inert conditions

All components in contact with the sample are inert. Contamination of the sample is prevented as leaching of additives from sealing membranes is eliminated.

Higher safety standards

Higher safety standards

Complete tightness of joints and a protective shield guarantee excellent operator protection. Cooling water, level of solvent and heat source are monitored at any time.

Voice of the customer

"Reliable product, extraction can run overnight, safe handling of volatile samples." Since 1989 the BUCHI Rotavapor is familiar in our research lab. BUCHI Rotavapors are safe and provide a very good working method. The pump has definitely simplified processes. We have passed from days to only hours of work. BUCHI's service has always been impeccable.
