Perform economic fat determination in food and feed samples with the E-816 ECE (Economic Continuous Extraction). The automated continuous extraction method ensures simple method selection and easy operation. Highest solvent recovery and reduced solvent consumption guarantee cost savings.

Benefits

Economic

  • Low solvent consumption due to the compact design of the glass assembly
  • More than 90% recycling yields thanks to minimized solvent emission and cooled tank

Convenient

  • Quick and simple method selection thanks to intuitive solvent library
  • Minimal operator intervention thanks to easy sample loading
  • Increase operator availability due to unattended process for walk-away

Fast and reliable

  • Up to four times faster compared to extractions using classical glassware
  • High reproducibility and reliable results thanks to continuous extraction method
  • Automated and compliant Twisselmann extraction (according to ISO, etc.)
  • High speed heating due to ceramic plates and individual heating zones

Expert Advice

When is it recommended to work with a recirculating chiller?

When you use a solvent like petroleum ether, a recirculating chiller should be implemented if the tap water is warmer than 15 °C. The temperature difference between the boiling point of the solvent and the cooling water temperature should be 20 - 25 °C in order to achieve a good condensation of the solvent in the condenser and to keep a good solvent recovery.

Can I re-use solvent from the tank?

Yes, all material is resistant, solvent is drained directly from the condenser.

Where do you fill the solvent?

It is an advantage to fill it by the condensers (first cycle is quicker).

Is it possible to install the unit outside of a fume hood?

Yes, only when working with D-Ether (volatility) or chloroform (toxicity), working in the fume hood is necessary.

What are the reasons to adjust the heating plate / user panel?

Boiling behavior is depending on sea level, ambient temperature and different solvent compositions (petroleum ether 40-60).

Set of glass beakers

The beakers are specially designed for the BUCHI extraction units. The bottom of the beaker is perfectly plane, which gives excellent heat transfer. The lip of the beaker is manually polished to ensure the best tightness of the system.

Recirculating chiller for E-812 / E-816 SOX or HE

The temperature difference between the boiling point of the solvent and the cooling water temperature should be 20-25°C in order to achieve good condensation of the solvent in the condenser and to achieve a good solvent recovery throughout the extraction.
