Overview

Benefits

Save time and money

Run 6 samples simultaneously by just pushing one button
Reduced solvent consumption and lower running costs
High speed heating with ceramic plates and individual heating zones
Achieve the best reproducibility thanks to time AND cycle control

Easy to use

Quick method selection of the entire process including rinsing and drying
Intelligent heating power selection by using the solvent library
Unattended operation due to cycle and/or time monitoring

Safe and compliant

Minimized solvent emissions thanks to z-seal-system and high performance condenser
Optimal recycling as a result of a cooled solvent tank (recovery > 90 %)
No risk of burns by effective shielding and heating control
The SOX configuration is a fully compliant real Soxhlet apparatus

Features

Automated hot extraction according to Randall or Goldfisch

Official method for many extractions, e.g. crude fat determination, a hydrolysis step prior to extraction may not always be necessary.

Clever menu navigation and solvent library

Easy to understand from the beginning. Choose your solvent and respective settings are loaded. No time-consuming application work necessary.

Best solvent recovery rates

Insulated tank with condenser, no unpleasant odor even with petroleum ether.

High speed heating

Ceramic surface with integrated individual heating zones. Every heating plate reaches boiling point within five minutes.

Expert Advice

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

Read more about 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.

When is it recommended to work with a recirculating chiller?

Read more about 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?

Read more about 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?

Read more about Where do you fill the solvent?

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

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

Read more about 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).

What are the main advantages of the HE unit?

Read more about What are the main advantages of the HE unit?

The E-812/ E-816 HE run an automated hot extraction according to Randall or Goldfisch.
Efficient extraction to determine crude fat.
Much faster than Soxhlet extraction (40 min instead of 120 min).

Options

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 F-305 / F-308 / F-314

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.
