Hot surfaces
The surfaces of the device can become very hot. If touched they can cause skin burns.
u Do not touch hot surfaces or else wear suitable protective gloves.
Empty beakers on heating plates
Empty beakers on active heating plates lead to very hot surfaces and can damage the instrument u u
Remove empty beakers from the instrument.
Deactivate heating positions not used.
Mechanical damages
If a device is damaged, sharp edges, moving parts or exposed electrical wires can cause injuries.
u u u
Check device regularly for visible damage.
Make sure that the locking mechanism of the protection shield is working properly.

Glass breakage
Broken glass can cause severe cuts.
Not visible cracks on glassware can lead to breakage.
Minor damage to the ground joints impairs the sealing effect and lead to loss of solvent during the extraction process.
u u u u u u u
Wear protective gloves when handling broken glassware.
Handle the glass components carefully and do not drop them.
Always place the glassware in a suitable holder when they are not in use.
Prevent any mechanical impact.
Prevent thermal shocks on glassware.
Always visually inspect glass components for damage every time they are used.
Do not continue to use glass components that are damaged.
Glass damages during extraction process
Glass damages during the extraction process can cause instrument damages caused by solvents, coolant and fire.
u If fault occurs:
Switch off the device immediately.
Unplug the power cord.
Inform the operator.
Let the temperature of the instrument decrease under observation until it is the same as the ambient.
Overfilled extraction beakers

Product description | 3
Description of function
The FatExtractor E-500 is designed to carry out the following solid-liquid extraction methods:
Soxhlet Extraction (see Chapter 3.1.1 "Soxhlet Extraction", page 13)
Hot Extraction (see Chapter 3.1.2 "Hot Extraction", page 14)
Economic Continuous Extraction (see Chapter 3.1.3 "Economic Continuous Extraction", page 14)
Soxhlet Extraction
Step 1 extraction
The sample is located in the extraction chamber.
The beaker contains the solvent.
The solvent is heated, vapor rises up to the condenser, condenses and drops into the extraction chamber with the sample.
The magnetic valve is closed, the solvent is collected up to the optical sensor and extracts the analyte.
When the optical sensor is reached, the magnetic valve opens and the solvent containing the analyte flows back into the beaker.
Step 2 rinsing
The solvent is heated, vapor rises up to the condenser, condenses and drops into the extraction chamber with the sample.
The magnetic valve is open, the solvent flows back into beaker, the solvent is not collected.
This flushes traces of fat into the beaker.
Step 3 drying
The solvent is heated, vapor rises up to the condenser, condenses and flows into tank.
The analyte remains in the beaker.

Hot Extraction
Step 1 extraction
The sample is located in the beaker.
The beaker contains the solvent.
The solvent is heated, vapor rises up to the condenser, condenses and drops into the beaker with the sample.
Step 2 rinsing
The solvent in the beaker is heated up and evaporated.
The vapor rises up to the condenser.
The condensed solvent flows into the beaker with the sample.
The tank bottle valve opens periodically and condensed solvent flows in the tank bottle.
The solvent level reduce.
Step 3 drying
The solvent in the beaker is heated up and evaporated.
The vapor rises up to the condenser.
The tank bottle valve is open and condensed solvent flows in the tank bottle.
The analyte remains in the beaker.
Economic Continuous Extraction
Step 1 extraction
The sample is located in the extraction chamber.
The beaker contains the solvent.
The solvent is heated, vapor rises up around the sample to the condenser, condenses and drops back into extraction chamber through the sample into the beaker.
Step 2 drying
The solvent is heated, vapor rises up around the sample to the condenser, condenses and flows into tank.
The analyte remains in the beaker.
