Laboratory vacuum pump MZ 2C EX

for rotary evaporatorsdiaphragmmulti-stage

Overview

• Outstanding chemical resistance and superior vapor tolerance
• Flameproof motor with integrated, self-locking overload and excess temperature protection for direct 230 V / 50 Hz single-phase supply; no additional overcurrent protection required
• Overpressure safety relief valves internally and at outlet
• Safety diaphragm technology with option for inert gas purge and detection of diaphragm breakage
• Inlet separator AK and emission condenser EK for pump protection and solvent recovery

Product description
ATEX chemistry vacuum systems are ready-for-use units configured for applications with large amounts of condensable vapors. Typical applications include rotary evaporators and drying ovens in potentially explosive atmospheres. The inlet separator (AK) retains particles and liquid droplets. The outlet emission condenser (EK) is compact and highly efficient, enabling near-100% solvent recovery. A separate gas ballast connection for use with inert gas is included with delivery.
