查询词典 vacuum bulb

In the state of vacuum,the boilling point of raw material will be dr-opped.therefore it is suitable for drying raw materials that are unstable or thermalsensitive.the vacuum drier also has good airtighenss.so it is also for drying raw materials that contain strong irriative and toxic gases and toxicgases and the solvent needs to recover.
