提氏索取器是一种用于连续提取植物有效成分的常用仪器,其主要原理为通过溶剂回流及虹吸现象,使固体中的成分每次均为纯净的溶剂所提取、其效率极高并节省溶剂。但一般索氏提取器容量较小,目前市售最大规格仅为100ml,不适宜对较大量原料进行提取,给实际运用带来不便。为此,我们参考了有关文献自制了一种容量可达1000ml的大容量索氏提取器。 Thithoffer is a commonly used instrument for the continuous extraction of active ingredients from plants. Its main principle is that the components in the solid are extracted by pure solvent every time the solvent is refluxed and siphoned. The efficiency is high and it saves. Solvents. However, the general Soxhlet extractor has a small capacity, and the largest size currently available on the market is only 100 ml, which is not suitable for the extraction of a relatively large amount of raw materials, which brings inconvenience to practical use. For this reason, we referenced the relevant literature to create a large-capacity Soxhlet extractor with a capacity of up to 1000 ml.
