3.1.2 Soxhlet Extraction (with and without chamber heater)
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 level
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.
3.1.3 Continuous Extraction (with and without chamber heater)
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 open, the solvent extracts the analyte and
flows back into the beaker.
Step 2 drying
 The solvent is heated, vapor rises up to the condenser, condenses
and flows into the tank bottle.
 The analyte remains in the beaker.
