Laboratory vacuum pump PC 3012 NT VARIO select DUO

diaphragmoil-freedry

Overview

• VACUU·SELECT vacuum controller with graphical user interface and predefined vacuum processes; easy integration via digital or analogue interfaces
• Automatic boiling point detection and vacuum adjustment for short process times
• Designed to meet vacuum requirements for very large quantities of most high-boiling solvents
• Long diaphragm lifetime for reduced operational and service costs
• Environmentally compatible: low energy consumption, oil- and water-free operation, efficient solvent recovery

Product description
The VARIO® DUO pumping units combine two VARIO® pumps connected in parallel on the inlet side and are driven synchronously by a single VACUU·SELECT vacuum controller. The controller synchronises pump speeds and controls vacuum accurately to match process requirements. It provides predefined vacuum programs, automatic boiling point detection and allows fully automatic or reproducible program sequences without user pre-settings. Integration into existing control systems is possible via digital and analogue interfaces. The oil‑ and water‑free diaphragm design and chemically resistant materials make the unit suitable for universal use in chemistry and pharmaceuticals.
