Troubleshooting of Zhengzhou Greatwall Glass Reactors
GR-series speed-regulation glass reactors are mainly used for synthetic reaction, distillation and concentration of different types of materials. We have single wall and double wall glass reactors.
The reactor can be pumped to a negative pressure state according to some experimental requirements. A constant pressure funnel or an adjusting valve on the feeding bottle allows you to add material the vessel at a uniform and controlled speed. Condenser helps to recover some materials distillated during reaction.
Single wall glass reactor has no jacket.
Double wall glass reactor has a jacket. Circulating liquid can be filled into the jacket to heat or cool materials inside.
We have 1L/2L/3L/5L/10L/20L/30L/50L/80L/100L Glass reactors for you to choose from.
