脂肪测定仪与索氏提取器的区别

The method of "fat tester extraction" requires the use of a crude fat tester, which is mainly the extraction process. The coarse-fat tester is composed mainly of heat extraction, solvent recovery ａnd cooling. Operation can be regulated according to different reagent boiling point ａnd the environmental temperature ａnd heating temperature, sample extraction process with repeated immersion ａnd extraction, so as to achieve rapid determination

Compare the two methods are as follows: extracted by soxhlet extractor, join the methanol in the process of experiment are concentrated by evaporation, volatilization of organic solvent not only caused certain pollution to the air, ａnd cause personal injury to the researchers. If the rotary evaporator is used to recycle the organic solvent, it is easy to make a large measurement error because of the transfer of the extract from the container. The method of extracting the solvent is avoided by using the method of fat meter extraction, which can be easily condensed ａnd recycled.

Practice, soxhlet extractor in extraction ａnd enrichment of two link conversion to change different instruments, process is more complex, while fat tester does not exist at this stage, just turn the knob can complete the transformation, ａnd the oil content meter has six extraction bottle, for the determination of large quantities of materials, than the traditional method has obvious advantages.
