3.1.1 Economic Continuous Extraction (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 around the sample to the con-
denser, 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 con-
denser, condenses and flows into tank.
 The analyte remains in the beaker.
