MD4C NT VARIO^® Self Adjusting Vacuum System

The VACUUBRAND MD4C NT VARIO^® vacuum system features a sophisticated vacuum controller that adjusts the pump speed, eliminating the need for solenoid valves or pump switching. It includes the new CVC3000 controller with intuitive "turn-and-push" jogwheel graphic interface for easy operation. It offers control options previously unavailable with vacuum pumps, such as:

Automatic Evaporation Control
The MD4C NT VARIO^® can automatically find and follow boiling point curves, continuously optimizing vacuum levels for maximum evaporation without bumping. The result: evaporation up to 30% faster than conventional electronic vacuum controllers.

Single Point Vacuum Control
The MD4C NT VARIO^® can maintain stable, hysteresis-free vacuum at a single setpoint.

Of course, the MD4C NT VARIO^® shares all of the other performance features of our other chemistry-design diaphragm pumps, like elimination of oi-changes, flowpaths constructed of corrosion-resistant fluoropolymers, integrated gas ballast and low-maintenance - typically 10,000-15,000 hours between service intervals. Individually accessible diaphragms and valves simplify servicing.

The MD4C NT VARIO^® has an ultimate vacuum of 1.1Torr (1.5mbar), and a free air capacity at maximum speed of 77lpm (2.7cfm).
