rotary evaporator

The method consists of ultrasonic extraction of colistin sulfate in feed sample, condensation of the extraction liquid by rotary evaporator, and determination by HPLC.

该方法首先用超声波法提取饲料中的硫酸粘杆菌素，通过旋转蒸发将提取液浓缩后，利用HPLC进行检测。

Use of a rotary vacuum evaporator will expedite the concentration steps in the procedure.

使用一座旋转真空蒸发器将会加快操作手续的浓缩过程.
