一种简易连续萃取装置的实验研究

The Device's Experiment Research on a Simple Continuously Withdraw

研究了一种连续萃取装置,并用这种装置代替Soxhlet萃取器进行了提取实验.结果表明,使用这种装置具有操作简便;减少溶剂消耗,降低实验成本;适合少量物质的提取;更不容易损坏;提取效率高。

A the kind consecutive extraction instruments are researched in this paper, by using the instruments to extract caffeine instead of Soxhlet extractor. It is demonstrated that these instruments have many advantages as follows：The operation is simple eonveniem ; Decreasing the consumption of solvent, lowering the cost of experiment ;Suitable for extracting a small amount of materials;It＇s not easily damaged;High extraction effectiveness can shorten the time of experiment.
