Warning: The instrument can not provide the designed protection for

operators who do not follow the right procedures and requirements given by
the manufacturer.

Warning: All solutions must be handled with care according to the

lab’s safety regulation. Please make a reference to the related material safety

data sheet. Wear the lab-gown, goggle and rubber gloves all the time. Be
care of hot reagents.

Warning: Be aware of the risk of electric shock. Only the trained
professionals are permitted to open the face panel or back cover.

I. Summary

1. Application

)$46 Fat Analyzer, designed in accordance with GB/T 14772-2008, can
be used not only in measuring the fat content in food, diary product and
feedstuff, but also in testing the soluble organic compound in detergent,
medicine, petrochemicals, fiber products, soil and sewage etc.
For example:
(1). To test the fat content in the food, feedstuff, grain, and seed.
(2). To extract the fat from the sewage and mud.
(3). To extract the semi-volatile organic compound such as pesticide and
weedicide.
(4).To extract plasticiser from plastics; to extract colophony from the paper; to
extract grease from the leather.
(5).To perform the pre-digestion process to the solid samples for the Gas
chromatography (GC) or Liquid chromatography (LC).

2. Principle

Based on the principle of Soxhlet extraction, )$46 uses the weighing
method to obtain the fat content. After being extracted from the sample by
solvents such as absolute ether or petroleum ether, the fat is dried and

weighed. The difference between the vessel’s weights before and after the

extraction is the fat content.

(6).The elevation connection using the transmission technique of the linear
bearing brings the flexible elevating operation.
(7).All information can be clearly displayed on the screen. The preset
temperature, actual temperature and heating time can be displayed
simultaneously on the screen.
(8).The safe operation is ensured because the electric circuit is completely
isolated with the extraction cell.
(9).With the unique air space insulation technique, the temperature of
instrument’s case can be kept normal.
(10). Compared with the traditional soxhlet extraction, its speed and
efficiency are better.

3. Working Condition

(1). Input voltage: 220V 50Hz；air break switch and leakage circuit breaker
are required.
(2). The apparatus should be placed where water, drain basin, electric pocket
are available.
(3). Power supply should meet the requirements of the apparatus to avoid
electric over stress; independent switch, safety device and reliable grounding
are required.
(4). The apparatus should be placed away from big electric equipment to
avoid strong magnetic field.
(5). Ensure the good ventilation of the laboratory.
