名称：全自动索氏萃取仪

厂家：步琦实验室仪器公司

规格型号：BUCHI B-811  

购置时间：2017年

开展实验：索氏萃取（400元/样）

主要技术指标：尺寸638x595x613mm；重量42kg；连接电压100-240V（+/-10%VAC）；功率max.1300W；频率50/60Hz；溶剂回收＞90％；用水量max.1.7L/min。使用光学传感器、大功率加热装置和优化型玻璃组件等高端组件，缩短循环时间；轻松更换符合索氏萃取法、Randall (HE) 和 Twisselmann (ECE) 要求的玻璃组件；模块化设计，通过更换玻璃配件实现索式提取法、索式提取大体积、热萃取法、连续萃取法4种模式切换；全自动系统，设定程序后仪器自动完成所有测量步骤。每个浸提过程包括三个步骤：萃取、淋洗、预干燥和溶剂回收；带有独立加热区的一体化陶瓷表面，在5min内即可达到设定温度。
