Applications of Vacuum Controller
- Rotary Evaporation: Vacuum control during solvent evaporation and concentration.
- Gradient Distillation：Programmable vacuum control for progressive distillation workflows.
- Reduced-Pressure Concentration: Controlled vacuum for laboratory sample concentration.
- Low-Boiling Solvent Recovery: Controlled evaporation of compatible low-boiling solvent systems.
- Corrosive Vapor Handling：Vacuum control for compatible acidic or alkaline vapor environments.
Why Use a Vacuum Controller?
Stable Vacuum Adjustment
Set the required vacuum directly instead of relying only on manual valve adjustment.
Progressive Distillation Control
Programmable vacuum stages allow the vacuum level to change gradually during a distillation process.
Low-Boiling Solvent Recovery
Controlled vacuum can help reduce excessive solvent loss during applicable low-boiling solvent evaporation.
Repeatable Workflows
Programmed conditions reduce repeated manual vacuum adjustment during similar experiments.
