Extracts fat from a dried, ground food sample with a repeatedly recycled organic solvent. The solvent is then evaporated and the fat left behind is weighed.

Soxhlet calibration procedures
Instrument qualification (DQ · IQ · OQ · PQ)
- 01
DQ — Design qualification
Defines number of positions, solvent compatibility, heating range, solvent recovery, safety cut-outs and ventilation needs.
- 02
IQ — Installation qualification
Records the unit, glassware, cooling water and exhaust connections, and safety devices as installed.
- 03
OQ — Operational qualification
Checks heating plate temperature, timer, solvent recovery and safety cut-outs (over-temperature, low water flow) work as specified.
- 04
PQ — Performance qualification
Shows that fat results on a reference material agree with the certified value and that duplicates meet the method repeatability.
Keep every Soxhlet in control: usage logs, calibration and maintenance schedules, and automatic blocking of overdue instruments.
