Heavy-walled and flexible.

Vacuum regulator valve for ME 1, ME 1C and MZ 1C with manual vacuum control using air bleed. The manometer can be mounted and pivoted in several orientations for optimal visibility. High chemical compatibility (especially with the vacuum regulator valve for ME 1C)

Premium module: The premium module comprises the inert gas inlet (only sizes 49/101), extra connectors for thermoshelves, one for VO29, two for VO49/VO101, an additional thermoshelf for model size 49/101.

Vacuum pump module: Without pump with antivibration metal plate at the bottom to accommodate the vacuum pump, including full-sight glass door, socket, signal cable and connecting hose to the vacuum oven.

Chemical-resistant vacuum pump: With 4x diaphragm, pump capacity: approx. 50 Nl/min = 3.0 m/h³, automatic purge control, with signal cable (3 m) to control the rotation speed and vacuum connecting hose (3 m).

• Improved performance, increased pumping speed and lower ultimate vacuum extends applications in both the laboratory and in industrial applications
• Long-life diaphragm with PTFE sandwich construction and unstressed diaphragm support
• Easy service/exchange of diaphragm or valves due to novel integrated valve head assembly. Easy dismantling, cleaning and reassembly without requiring readjustment
• Very quiet and ultra low vibration due to compact drive with patented motor control system. Ideal as a built-in component for sensitive equipment in both the laboratory and in industry
• Superior vapour tolerance due to integral tubing connections and gas ballast valve for continuous purge (for ME 16C NT, MZ 2C NT, MD 4C / 12C NT and MV 10C NT)
• Easy to clean due to smooth exterior surfaces

The VARIO^® design provides vacuum control by precise and continuous adaption of the chemistry diaphragm pumps motor speed, and includes the vacuum pump, as well as the VACUU·SELECT controller.

Diaphragm pump MD 4CRL NT with reduced leakage rate (0.001 mbar x l/s).

Country-specific power cord versions available on request.

Characteristics and applications:
Without vacuum control:
MZ 2C NT +2AK: e.g. filtration, distillation without condensation at the outlet
MZ 2C NT +AK+EK: Well-proven unit for a wide range of applications for a single-user, e.g. gel drying, distillation, vacuum concentrator. For solvents with medium to low volatility.
MD 1C +AK+EK: Space-saving single-user configuration. For high-boiling-point solvents.
MD 4C NT + AK+EK: Larger or multi-user applications, the local vacuum network VACUU·LAN^®. For high-boiling solvents.
MV 10C NT +EK: Four-stage diaphragm pump with exhaust vapour condenser. For particularly high demands regarding low ultimate vacuum and pumping speed in chemistry laboratories, pilot plant or small production units.
