VACUUBRAND MZ 2C NT Chemistry Diaphragm Pump Overview
The VACUUBRAND MZ 2C NT is one of the most versatile chemistry diaphragm pumps in the VACUUBRAND lineup. Its two-stage design provides significantly deeper vacuum than basic filtration pumps while maintaining the oil-free, chemically resistant advantages that make diaphragm technology attractive for solvent and reagent applications.
All components exposed to pumped media are manufactured from chemically resistant fluoroplastics. VACUUBRAND also uses PTFE sandwich diaphragms designed to increase reliability and service life under demanding laboratory conditions. This construction makes the MZ 2C NT particularly well suited for continuous pumping of chemical vapors that would contaminate the oil in a conventional rotary vane pump.
The integrated gas ballast valve improves condensable-vapor handling by allowing continuous condensate purge. This helps maintain useful pumping performance when water vapor or other condensable substances are present during evaporation, concentration, or drying workflows.
VACUUBRAND identifies the MZ 2C NT as its most popular chemistry diaphragm pump, and the platform serves as the basis for multiple complete vacuum systems with separators, condensers, gauges, and automated controls. (shop.vacuubrand.com)

Energy Efficiency & Operating Costs
The MZ 2C NT uses a 180-watt motor and operates without vacuum pump oil. This eliminates oil purchases, oil changes, contaminated-oil disposal, oil mist, and oil backstreaming into laboratory processes.
For laboratories working with solvents or corrosive vapors, oil-free operation can also reduce maintenance because there is no oil reservoir available for solvent contamination. The maintenance-free drive system and long-life PTFE sandwich diaphragms are designed to further reduce routine service requirements.
The compact pump body also allows laboratories to dedicate the MZ 2C NT to a particular evaporator, concentrator, or vacuum workstation without requiring a large centralized vacuum installation.

Common Applications
The VACUUBRAND MZ 2C NT is particularly well suited for rotary evaporation, vacuum concentration, solvent evaporation, evacuation, degassing, vacuum drying, filtration, and pumping corrosive gases and vapors.
Its 7 mbar ultimate vacuum gives it significantly more capability than general-purpose filtration pumps while remaining oil-free and chemically resistant.
Ideal Laboratory Types
The MZ 2C NT is an excellent choice for pharmaceutical research laboratories, biotechnology companies, organic chemistry laboratories, medicinal chemistry groups, analytical laboratories, environmental testing facilities, university research laboratories, contract research organizations, and industrial R&D facilities.
It is especially useful for laboratories operating rotary evaporators, vacuum concentrators, drying systems, filtration manifolds, and other equipment where chemical vapor resistance and low maintenance are important.
Chemical Resistance & Vapor Tolerance
Chemical resistance is one of the defining strengths of the MZ 2C NT.
VACUUBRAND manufactures the wetted components from chemically resistant fluoroplastics, while PTFE sandwich diaphragms provide a robust barrier between the process gases and the mechanical drive system.
This makes the pump particularly useful for continuous handling of aggressive or solvent-rich vapors that can quickly degrade general-purpose vacuum pumps.
Chemical compatibility should still be verified for the specific substances, concentrations, temperatures, and operating conditions involved.
Two-Stage Vacuum Performance
The MZ 2C NT uses a two-stage diaphragm arrangement to achieve an ultimate vacuum of approximately 7 mbar / 5 Torr.
Two-stage construction allows substantially lower ultimate pressure than a single-stage diaphragm pump while maintaining useful pumping speed.
This pressure range supports many common laboratory evaporation and concentration workflows, especially when reduced boiling temperature is desirable for heat-sensitive samples.
Gas Ballast & Condensable Vapor Handling
The integrated gas ballast valve helps improve performance when condensable vapors are present.
Without gas ballast, the MZ 2C NT reaches approximately 7 mbar. With gas ballast in use, ultimate vacuum is approximately 12 mbar / 9 Torr.
Gas ballast allows condensate to be purged more effectively during pumping, which can be useful for water vapor and suitable solvent vapors generated during evaporation or drying processes.
MZ 2C NT for Rotary Evaporators
The MZ 2C NT is a strong vacuum source for many laboratory rotary evaporators.
Its 7 mbar ultimate vacuum supports evaporation of numerous common solvents at reduced temperatures, while the chemistry-resistant diaphragm design avoids the oil contamination issues associated with rotary vane pumps.
Because the standard MZ 2C NT is a fixed-speed pump without automatic electronic vacuum control, vacuum regulation may be handled with a manual valve, external vacuum controller, or compatible accessory depending on the process.
For laboratories that want automated boiling-pressure detection and variable-speed control, the MZ 2C VARIO Select provides a more advanced solution.
MZ 2C NT for Vacuum Concentrators
VACUUBRAND also identifies vacuum concentrators among typical applications for the U.S. MZ 2C NT configuration. (shop.vacuubrand.com)
Vacuum concentration removes solvent under reduced pressure, often producing significant vapor loads. The MZ 2C NT's oil-free, chemically resistant construction makes it well suited for these workflows.
When liquid carryover or high condensate loads are expected, one of the MZ 2C NT system configurations with inlet or exhaust separators may provide additional protection.
MZ 2C NT for Chemical Vapor Pumping
The MZ 2C NT was specifically designed for the continuous oil-free pumping of corrosive gases and vapors.
This makes it useful for laboratories that need vacuum during synthesis, evaporation, evacuation, degassing, or analytical processes where solvent vapor is routinely present.
The absence of pump oil simplifies chemical-vapor handling and removes the risk of solvent-contaminated vacuum oil affecting performance.
MZ 2C NT vs. ME 1C
Both pumps are chemically resistant diaphragm pumps, but the MZ 2C NT provides substantially deeper vacuum.
The ME 1C reaches approximately 100 mbar and is particularly well suited for vacuum filtration, aspiration, and moderate-vacuum laboratory work.
The MZ 2C NT reaches 7 mbar, making it much better suited for rotary evaporation, vacuum concentration, solvent evaporation, and other applications requiring deeper vacuum.
For straightforward filtration, the ME 1C may be sufficient. For broader chemical vacuum duties, the MZ 2C NT offers significantly greater process capability.
MZ 2C NT vs. MZ 2C VARIO Select
Both pumps use two-stage chemistry diaphragm technology and reach approximately 7 mbar ultimate vacuum, but their control systems differ significantly.
The MZ 2C NT is a fixed-speed pump. It provides a dependable vacuum source that can be paired with manual controls, separators, condensers, or external controllers as required.
The MZ 2C VARIO Select incorporates variable-speed motor control and the VACUU·SELECT electronic controller for automatic pressure regulation and solvent boiling-point detection.
For laboratories that want a simple, durable chemistry vacuum pump, the MZ 2C NT is an excellent choice. For automated rotary evaporation and process control, the VARIO Select version provides additional capability.
MZ 2C NT vs. MZ 2C NT +2AK
The standard MZ 2C NT provides the core pumping platform without additional separators.
The MZ 2C NT +2AK adds inlet and outlet separators for improved liquid protection and condensate management.
If the pump will be used with processes where droplets, particles, or significant condensate are expected, the +2AK configuration may offer useful additional protection. For straightforward installations where those accessories are unnecessary, the standard MZ 2C NT provides the same core vacuum performance in a more compact package.
MZ 2C NT vs. MZ 2C NT +AK+EK
The MZ 2C NT +AK+EK adds a protective inlet separator plus a high-efficiency exhaust condenser for solvent recovery.
The standard MZ 2C NT is therefore the more straightforward choice when the laboratory already has suitable vapor trapping or does not require integrated solvent recovery.
The +AK+EK configuration is particularly valuable for rotary evaporation, concentration, and vacuum drying workflows where solvent recovery and emission reduction are important.
Recommended Laboratory Applications
The VACUUBRAND MZ 2C NT is recommended for:
Application suitability should always be evaluated based on required ultimate vacuum, pumping speed, vapor load, chemical compatibility, and process safety.
Why Choose the Standard MZ 2C NT?
The standard MZ 2C NT is attractive for laboratories that want the core performance of VACUUBRAND's MZ 2C platform without paying for accessories or process controls they may not need.
At only approximately 9.6" × 9.6" × 7.8", it is smaller than the complete +2AK, +AK+EK, and +AK+M+D systems. This allows it to fit easily beside evaporators, concentrators, vacuum manifolds, or laboratory instrumentation.
It can also serve as the foundation for a customized vacuum system if a laboratory later wants to add external vacuum regulation, liquid separators, condensers, or other accessories.
