3.1
3.1.1
BÜCHI Labortechnik AG
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 14)
Hot Extraction (see Chapter 3.1.2 "Hot Extraction", page 15)
Economic Continuous Extraction (see Chapter 3.1.3 "Economic Continuous Extraction", page 15)
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.
Step 3: Drying
The solvent is heated, vapor rises up to the condenser, condenses and flows into tank.
The analyte remains in the beaker.

3.1.2
Product description | 3
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 decreases.
Step 3: Drying
The solvent is heated, vapor rises up to the condenser, condenses 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.
