u Do not fill more than 175 mL in the extraction beakers.
u Do not fill more than 320 mL in the extraction beakers LSV.
u Do not fill more than 100 mL in the extraction beakers HE.
2.6.7 Spilled hazardous materials
It is the responsibility of the operator to ensure the safety of users and the selection of
correct decontamination agents.
u Make sure that the personal protective equipment meets the requirements of the
safety data sheets for the chemicals used.
u Make sure that the decontamination agent meets the requirements of the safety
data sheets for the chemicals used.
u Make sure that the decontamination agent is compatible with the materials used.
See Chapter3.5 "Technical data", page22
u If you have any further questions, contact BUCHI Customer Service.
2.6.8 Solvent leakages during extraction process

3 Product description
3.1 Description of function
The FatExtractor E-500 is designed to carry out the following solid-liquid extraction
methods:
Soxhlet Extraction (see Chapter3.1.1 "Soxhlet Extraction", page14)
Hot Extraction (see Chapter3.1.2 "Hot Extraction", page15)
Economic Continuous Extraction (see Chapter3.1.3 "Economic Continuous Extrac-
tion", page15)
3.1.1 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, con-
denses 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, con-
denses 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.
Step 3: Drying
The solvent is heated, vapor rises up to the condenser, con-
denses and flows into tank.
The analyte remains in the beaker.
14/88 Operation Manual FatExtractor E-500
Page 15
BÜCHI Labortechnik AG Product description | 3
3.1.2 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, con-
denses 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 decreases.
Step 3: Drying
The solvent is heated, vapor rises up to the condenser, con-
denses and flows into tank.
The analyte remains in the beaker.
3.1.3 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.
3.1.4 Description of the Analyte Protection Sensor (option)
The Analyte Protection Sensor protects the analyte from overheating.

4.1 Transport
NOTICE
Risk of breakage due to incorrect transportation
Make sure that the instrument is fully dismantled.
Pack every instrument components properly to prevent breakage. Use the original
packaging whenever possible.
Avoid sharp movements during transit.
u After transporting, check the instrument and all glass components for damage.
u Damage that has occurred in transit should be reported to the carrier.
u Keep packaging for future transportation.
4.2 Storage
u Make sure that the ambient conditions are complied with (see Chapter3.5 "Tech-
nical data", page22).
u Wherever possible, store the device in its original packaging.
u After storage, check the device, all glass components, seals and tubing for dam-
age and replace if necessary.

NOTICE
Instrument damage due to switching it on too early.
Switching on the instrument too early after transportation can cause damage.
u Climatize the instrument after transportation.
5.2 Installation site
The installation site must meet the following requirements:
Firm, level surface
Make sure that the installation site meets the requirements of the safety data
sheets for all solvents and samples used.
Inside a fume hood or minimum 500 mm space requirement above the instrument.
Make sure that no instruments generating heat or corrosive vapors are in the same
fume hood (e.g. HydrolEx H-506).
Take into account the maximum product dimensions and weight. See Chapter3.5
"Technical data", page22
Do not expose the instrument to any external thermal loads, such as direct solar
radiation or other ignition source.
Do not place any flammable devices or substances close to the instrument, as they
could ignite due to the heat from the heating plates.
Make sure that cables / tubes can be routed safely.
NOTE
Make sure that the power supply can be disconnected at any time in an emergency.
5.3 Establishing electrical connections
NOTE
Observe the regulatory provisions when connecting the instrument to power supply.
4 Use external main switches (e.g., emergency off) in accordance with the stan-
dards IEC 60947-1 and IEC 60947-3.
4 Use additional electrical safety features (e.g., residual-current circuit breakers) to
comply with local laws and regulations.
The power supply must fulfill the following conditions:
1. Provide the mains voltage and frequency specified on the type plate of the instrument.
2. Be designed for the load imposed by the instruments connected.
3. Be equipped with suitable fuses and electrical safety features.
4. Be equipped with a proper grounding.
