最近,国外开拓出一种称为混和分离系统(mix separatory systems)的新一代液—液萃取器,它具有精密、快速、高效率萃取等特点,因而取代了传统的分液漏斗萃取器。现浙江省海宁玻璃仪器厂在有关科研人员的支持下,根据国外先进原理,设计、试制了一批新型萃取器,经供有关单位使用效果极佳。目前该厂己试制有2、5、10、20、50毫升五种规格,并即将通 Recently, a new generation of liquid-liquid extractor called mix separatory systems has been developed abroad to replace the traditional separatory funnel extractor with the features of precision, fast and efficient extraction. Now Haining Glass Instrument Factory in Zhejiang Province, with the support of relevant scientific researchers, according to foreign advanced principles, design, trial production of a new batch of extractors, by the relevant units with excellent results. At present, the factory has trial production of 2,5,10,20,50 ml five specifications, and is about to pass
