VACUUBRAND MZ 2C NT +AK+M+D Overview
The MZ 2C NT +AK+M+D is designed for laboratories that need more than a basic vacuum pump but do not require automated electronic vacuum control.
At the heart of the system is VACUUBRAND's MZ 2C NT two-stage chemistry diaphragm pump, which provides an ultimate vacuum of 7 mbar. This allows the system to support filtration as well as evaporation, evacuation, degassing, and other applications requiring considerably deeper vacuum than a general-purpose filtration pump.
What differentiates the +AK+M+D configuration is the equipment installed around the pump.
The AK inlet separator provides protection against particles and accidentally aspirated liquid droplets. The M manual flow-control valve allows the operator to regulate effective pumping speed at the vacuum connection. The D vacuum manometer provides an analog indication of system vacuum.
Together, these features create a straightforward laboratory vacuum system that gives the operator direct visual feedback and manual control without the complexity or expense of an automated electronic vacuum controller.

Energy Efficiency & Operating Costs
The VACUUBRAND MZ 2C NT +AK+M+D uses a 180-watt motor and operates without vacuum pump oil. For laboratories running vacuum equipment routinely, oil-free operation eliminates the expense and maintenance associated with oil changes, contaminated-oil disposal, oil mist, and oil backstreaming.
The chemistry diaphragm design also incorporates a maintenance-free drive system engineered for long diaphragm and valve life. This can make the MZ 2C NT platform particularly economical for laboratories that require vacuum every day but want to minimize routine pump maintenance.
The manual flow-control valve provides another practical advantage. Operators can reduce effective pumping speed when full pump capacity is unnecessary rather than simply applying maximum vacuum to every process.
The AK inlet separator can also contribute to long-term pump reliability by helping prevent accidentally aspirated droplets and particles from reaching the pump heads.
Common Applications
The VACUUBRAND MZ 2C NT +AK+M+D is particularly well suited for vacuum filtration, membrane filtration, solid-phase extraction, vacuum manifolds, sample preparation, evacuation, evaporation, degassing, and pumping chemical gases and vapors.
Its combination of deeper vacuum, chemical resistance, manual regulation, pressure indication, and liquid protection makes it particularly versatile for laboratories that use one vacuum source for several different workflows.
Ideal Laboratory Types
The MZ 2C NT +AK+M+D is an excellent choice for analytical chemistry laboratories, pharmaceutical research facilities, biotechnology companies, environmental testing laboratories, microbiology facilities, university research laboratories, organic chemistry groups, contract research organizations, quality-control laboratories, and industrial R&D facilities.
It is especially attractive for laboratories performing filtration and sample preparation where operators benefit from being able to see the vacuum level and manually adjust pumping performance.
Manual Vacuum Control & Analog Manometer
One of the most important advantages of the MZ 2C NT +AK+M+D is its straightforward approach to vacuum regulation.
The manual flow-control valve regulates effective pumping speed at the vacuum connection. Rather than operating every process at the maximum vacuum the pump can produce, the operator can adjust vacuum according to the needs of the application.
The integrated analog manometer provides immediate visual feedback, allowing users to observe vacuum while making adjustments.
This combination is particularly useful for filtration and other processes where excessive vacuum may be unnecessary or undesirable.
Unlike an electronically controlled VARIO system, the MZ 2C NT +AK+M+D keeps operation simple and mechanical. For laboratories that do not need automated boiling-point detection or programmable vacuum sequences, this can be a practical and cost-effective approach.
Protective AK Inlet Separator
The AK inlet separator is another important feature of this configuration.
Constructed from glass with a protective coating, the separator is designed to retain particles and liquid droplets before they enter the vacuum pump.
This is especially useful for vacuum filtration. An overfilled filter flask, foaming sample, or accidental liquid aspiration can potentially send liquid into the vacuum line. The inlet separator provides an additional barrier between the process and the diaphragm pump.
Protecting the pump from liquid carryover can help reduce contamination, extend component life, and minimize unplanned downtime.
MZ 2C NT +AK+M+D for Vacuum Filtration
VACUUBRAND specifically identifies the MZ 2C NT +AK+M+D as a system well proven for filtration, making filtration an important application for this model.
The pump can support membrane filtration, microbiological filtration, environmental sample filtration, Buchner funnel filtration, solid-phase extraction, vacuum manifolds, and other laboratory filtration workflows.
Its manual flow-control valve is particularly useful in these applications because maximum vacuum is not always desirable. Operators can adjust effective pumping speed while observing system vacuum on the analog manometer.
The inlet separator provides additional protection against liquid carryover, creating a particularly well-rounded vacuum system for laboratories performing filtration regularly.
MZ 2C NT +AK+M+D for Solid-Phase Extraction
Solid-phase extraction workflows often benefit from a controllable vacuum source because excessive flow through an SPE cartridge can reduce extraction consistency.
The manual vacuum adjustment provided by the MZ 2C NT +AK+M+D allows operators to regulate effective pumping speed instead of relying solely on a full-vacuum source.
When connected to a compatible SPE manifold, the system can therefore provide a convenient oil-free vacuum source for analytical sample preparation.
Chemical Resistance & Oil-Free Operation
The MZ 2C NT is designed specifically as a chemistry diaphragm pump.
Chemically resistant wetted components make the pump suitable for handling many vapors encountered in chemical, pharmaceutical, and analytical laboratories. Unlike rotary vane pumps, the MZ 2C NT requires no vacuum pump oil.
This eliminates the possibility of solvents contaminating an oil reservoir and removes the need for routine oil changes.
Oil-free operation also prevents oil backstreaming into connected laboratory equipment, an important consideration for clean analytical and research workflows.
Chemical compatibility should always be confirmed for the specific substances, concentrations, temperatures, and process conditions involved.
Gas Ballast & Condensable Vapor Handling
The MZ 2C NT +AK+M+D incorporates gas ballast to improve operation with condensable vapors.
Without gas ballast, the system reaches an ultimate vacuum of approximately 7 mbar / 5 Torr. With gas ballast operating, ultimate vacuum is approximately 12 mbar / 9 Torr.
Gas ballast can help purge condensate from the pumping system during appropriate applications, improving performance when water vapor or other condensable materials are encountered.
MZ 2C NT +AK+M+D vs. MZ 2C NT +2AK
These two systems use the same basic MZ 2C NT chemistry diaphragm pump but are configured for different priorities.
The MZ 2C NT +2AK emphasizes liquid and condensate management, incorporating separators at both the inlet and outlet. It is particularly useful for vacuum concentrators, gel dryers, evaporation, and applications where condensate collection is important.
The MZ 2C NT +AK+M+D emphasizes manual vacuum regulation and monitoring. It combines an inlet separator with a manual flow-control valve and analog vacuum manometer, making it especially useful for filtration and processes where the operator wants direct control over vacuum.
Both reach approximately the same 7 mbar ultimate vacuum. The best configuration depends on whether the laboratory places greater importance on condensate collection or manual vacuum adjustment and pressure indication.
MZ 2C NT +AK+M+D vs. MZ 2C VARIO Select
The MZ 2C NT +AK+M+D and MZ 2C VARIO select represent two different approaches to vacuum control.
The MZ 2C NT +AK+M+D uses a manual valve and analog manometer. The operator observes vacuum and makes adjustments directly.
The MZ 2C VARIO select uses electronic variable-speed control and the VACUU·SELECT controller to regulate vacuum automatically. It is particularly valuable for rotary evaporation and distillation where automatic boiling-pressure detection can improve process control.
For filtration and straightforward laboratory vacuum applications, the simplicity of the MZ 2C NT +AK+M+D can be advantageous. For automated solvent evaporation, the VARIO select configuration provides substantially greater process automation.
MZ 2C NT +AK+M+D vs. ME 1C
Both models are oil-free chemistry diaphragm pumps, but they serve different levels of laboratory vacuum demand.
The ME 1C is a compact chemistry-resistant pump designed primarily for filtration, aspiration, and moderate-vacuum applications.
The MZ 2C NT +AK+M+D reaches 7 mbar and provides substantially deeper vacuum along with an inlet separator, vacuum manometer, and manual flow regulation.
For a dedicated single filtration station, the ME 1C may be sufficient. For laboratories needing a more capable and adjustable chemistry vacuum system that can support filtration plus evaporation, evacuation, and other processes, the MZ 2C NT +AK+M+D provides considerably more versatility.
