VACUUBRAND MZ 2C NT +2AK Chemistry Vacuum System Overview
The VACUUBRAND MZ 2C NT +2AK is designed for laboratory applications where chemical resistance, deeper diaphragm-pump vacuum, and condensate management are more important than sophisticated electronic vacuum control.
At the heart of the system is the MZ 2C NT, a two-stage chemistry diaphragm pump capable of reaching 7 mbar ultimate vacuum. This pressure range makes the system suitable for applications that require considerably more vacuum than routine filtration pumps such as the VACUUBRAND ME 1 or ME 1C.
The +2AK configuration adds separators at both the inlet and outlet, providing an important advantage for laboratory processes involving liquids and condensable vapors.
The protective glass inlet separator captures liquid droplets and particles before they can enter the pump. At the exhaust side, a second separator collects condensate, helps prevent condensate from flowing backward toward the pump, and contributes to quiet exhaust operation. VACUUBRAND specifically describes this configuration as appropriate for vacuum concentrators, gel dryers, filtration, evaporation, and pumping gases and vapors in chemical, biological, and pharmaceutical laboratories.

Energy Efficiency & Operating Costs
The MZ 2C NT +2AK uses a 180-watt motor and completely oil-free diaphragm pumping mechanism. Because no vacuum pump oil is required, laboratories eliminate routine oil changes, oil disposal, oil mist, and the possibility of oil backstreaming into connected laboratory equipment.
The diaphragm design also incorporates a maintenance-free drive system engineered for long diaphragm and valve life. For laboratories regularly handling chemical vapors, eliminating an oil reservoir also removes one of the principal maintenance concerns associated with conventional rotary vane pumps: solvent contamination of the pump oil.
The inlet separator can further contribute to long-term reliability by intercepting droplets and particles before they reach the pump, while the exhaust-side separator collects condensate rather than allowing it to migrate back into the pumping system.
Specifications compiled from current VACUUBRAND manufacturer literature and American Instrument Exchange product information.
Common Applications
The VACUUBRAND MZ 2C NT +2AK is particularly well suited for vacuum concentrators, centrifugal vacuum concentrators, gel dryers, vacuum filtration, solid-phase extraction, evaporation, evacuation, degassing, and pumping gases and vapors in chemical, biological, and pharmaceutical laboratories.
Its 7 mbar ultimate vacuum also makes the system useful for many evaporation and concentration applications that require deeper vacuum than a basic filtration pump can provide.
Ideal Laboratory Types
The MZ 2C NT +2AK is an excellent choice for pharmaceutical research laboratories, biotechnology companies, university research facilities, molecular biology laboratories, analytical chemistry groups, organic chemistry laboratories, environmental testing facilities, contract research organizations, and industrial R&D laboratories.
It is especially useful in laboratories operating vacuum concentrators, gel dryers, filtration manifolds, evaporation systems, and other equipment where liquid droplets or condensate may occasionally reach the vacuum line.
Chemical Resistance & Vapor Tolerance
The MZ 2C NT series is specifically designed for chemistry vacuum applications, providing substantially greater resistance to chemical vapors than general-purpose diaphragm pumps.
This makes the MZ 2C NT +2AK particularly useful where a laboratory needs oil-free vacuum but expects the pump to encounter solvent or reagent vapors during normal operation.
The system also provides an ultimate vacuum of 12 mbar with gas ballast, allowing condensable vapors to be purged while maintaining useful process vacuum. Chemical compatibility should always be evaluated for the particular chemicals, concentrations, and operating conditions involved.
Dual Separators for Liquid & Condensate Protection
The +2AK configuration is the key feature distinguishing this vacuum system from a standalone MZ 2C NT pump.
The inlet-side AK separator is constructed from protective-coated glass and is designed to retain particles and liquid droplets before they enter the vacuum pump. This provides an important safeguard in applications where accidental aspiration, foaming, or liquid carryover could otherwise reach the diaphragm heads.
The exhaust-side separator performs a different function. It collects condensate leaving the pump and helps prevent condensate from flowing backward toward the pump.
Together, the two separators make the MZ 2C NT +2AK particularly attractive for real-world laboratory processes where liquid management and pump protection are important.
MZ 2C NT +2AK for Vacuum Concentrators
VACUUBRAND specifically identifies vacuum concentrators as a typical application for the MZ 2C NT +2AK.
Vacuum concentration removes solvent from samples by reducing pressure, often in combination with centrifugal force and controlled heating. The MZ 2C NT +2AK's 7 mbar ultimate vacuum supports evaporation of many commonly encountered laboratory solvents, while its chemistry-resistant diaphragm design handles solvent vapors without requiring vacuum pump oil.
The inlet and outlet separators provide additional protection in concentration workflows where condensed solvent or accidental liquid carryover may be encountered.
MZ 2C NT +2AK for Gel Dryers
The MZ 2C NT +2AK is also well suited for laboratory gel dryers.
Gel drying requires stable vacuum to remove moisture while preserving electrophoresis gels for imaging, documentation, autoradiography, or long-term storage. The MZ 2C NT provides significantly more vacuum than a simple filtration pump while maintaining quiet, oil-free operation suitable for molecular biology and biochemistry laboratories.
MZ 2C NT +2AK for Vacuum Filtration
Although the MZ 2C NT +2AK provides substantially deeper vacuum than is necessary for many filtration procedures, it can also support vacuum filtration, membrane filtration, solid-phase extraction, and vacuum manifold applications.
The inlet separator is especially useful in these applications because it provides additional protection against accidental aspiration of liquid into the pump.
For laboratories performing only straightforward single-station filtration, a smaller ME 1 or ME 1C may be more economical. The MZ 2C NT +2AK becomes particularly attractive when the same vacuum system will also support deeper-vacuum concentration, drying, or evaporation processes.
MZ 2C NT +2AK vs. MZ 2C VARIO Select
Both systems use chemically resistant, oil-free diaphragm technology and reach approximately 7 mbar ultimate vacuum, but they are optimized for different workflows.
The MZ 2C NT +2AK is a fixed-speed chemistry vacuum system featuring inlet and outlet separators. Its strengths are simplicity, chemical resistance, liquid protection, condensate collection, and reliable vacuum for concentrators, gel dryers, filtration, and general evaporation.
The MZ 2C VARIO select adds variable-speed operation and an electronic VACUU·SELECT controller capable of automatically detecting solvent boiling pressure and regulating vacuum. It is therefore the stronger choice for processes such as rotary evaporation where precise, automated pressure control is particularly valuable.
For a laboratory needing robust fixed-speed chemical vacuum with enhanced liquid and condensate management, the MZ 2C NT +2AK is an excellent solution.
MZ 2C NT +2AK vs. ME 1C
The ME 1C and MZ 2C NT +2AK are both chemistry-resistant diaphragm vacuum pumps, but their vacuum capabilities differ substantially.
The ME 1C reaches approximately 100 mbar and is particularly well suited for routine filtration, aspiration, and moderate-vacuum applications.
The MZ 2C NT +2AK reaches 7 mbar, allowing it to support vacuum concentration, gel drying, evaporation, and other applications requiring considerably deeper vacuum. It also adds dedicated inlet and outlet separators for liquid and condensate management.
For simple filtration, the ME 1C may be all that is necessary. For laboratories needing a more versatile chemistry vacuum source capable of supporting multiple types of laboratory equipment, the MZ 2C NT +2AK offers substantially greater capability.
Recommended Laboratory Applications
The VACUUBRAND MZ 2C NT +2AK is recommended for vacuum concentrators, centrifugal concentrators, gel dryers, vacuum filtration, membrane filtration, solid-phase extraction, evaporation, degassing, evacuation of laboratory apparatus, and general chemical-vapor pumping.
For applications where solvent recovery through active outlet condensation is a priority, laboratories should consider an appropriately configured VACUUBRAND chemistry vacuum system with an emission condenser.
