General Description
The Labconco Goldfisch Fat Extraction Apparatus is designed for single or
multiple fat extractions according to the methods prescribed in the
Association of Official Analytical Chemists (AOAC) or other technical
methods involved with the use of a continuous extractor.
These units operate on a continuous type extraction principle; however, the
refluxing time normally required by the Soxhlet Extraction Method is usually
reduced through the design principles incorporated in the Goldfisch
Extractors.
The following instructions outline the features, installation and maintenance
of the Goldfisch Extractor. This manual should be kept handy so that
questions of use or service can be answered.
Component Identification
Refer to Figure 1 for the specific location of these components.
1.
Manifold Assembly. This assembly is located at the top of the apparatus
and provides an even flow and distribution of water to the condenser
heads. Water exits through the water control valve, located on the upper
left hand portion of the unit. And flows through the manifold assembly,
depositing cool water in the condenser head system.
2. Pressure Release Valve . These valves are located at the top of the
manifold above each of the condensers. It provides an escape for excess
gaseous pressure which may build up in the condenser. The valves
automatically reset themselves to assure a closed system of extraction.
3. Condenser Head System . These cylindrical shaped condensers located
above each heater provide an essential part of the extraction process. The
solvent vapor rises from the boiling solvent and reaches a point inside the
condenser head coming into contact with metal cone shaped surface
which is cooled by water. The vapors condense and drip through the
sample held in the ceramic thimble, extracting the fat from the sample.
4. Heater System . Each 100 watt adjustable spring loaded heater provides
an even distribution of heat through the use of coiled heater wires
embedded in a ceramic material. The variable heat control switch located
at the front of the unit provides a variety of settings.
