带 HPLC 接口的自动多通道流通池溶出系统
Regulated labs filing extended-release profiles need fractions timed and traceable without staff on shift. This software-controlled system runs 6–8 channels in parallel and sends samples to an HPLC autosampler or UV flow cell. Programmable flow from 1 to 50 mL/min supports pH-gradient methods and overnight runs.
