The Wiggens DVR480 is a multifunctional vacuum controller designed for chemical laboratory processes, most notably for precise solvent recovery on a rotary evaporator. It is frequently used with Wiggens Rotary Evaporators to enhance distillation efficiency through multi-step vacuum control. All parts that come into contact with gases are made of PTFE or highly durable ceramic to ensure the resistance to various acid, base, or organic solvent gases.

• Controllable Range: Precise vacuum control from 0.1 mbar to 1000 mbar.
• Multi-Step Programming: Supports up to 5-step vacuum control, which is highly effective for distillations involving dual or multiple boiling points.
• Chemical Resistance: All parts in contact with gas or condensate (such as the sensor and valves) are made of PTFE or highly anti-corrosive ceramics.
• Connectivity: Features both RS-232 and analog connections for remote control via PC or integration into larger chemical reaction systems.
• Safety Features: Includes a pressure release feature and allows for direct electric control of the connected vacuum pump

• Solvent Recovery: Precise management of boiling points to maximize recovery rates on rotary evaporators.
• Chemical Reactors: Maintaining vacuum-stat processes inside sealed reactors.
• Distillation: Automated control for complex mixtures with varying volatility.
