VACUUBRAND ME 2 NT Diaphragm Pump Overview
The VACUUBRAND ME 2 NT is engineered for laboratories that require more pumping capacity than a small single-station diaphragm pump but do not need the deep vacuum or chemical resistance of more specialized systems.
Its one-stage design provides an advantageous combination of high pumping speed and 70 mbar ultimate vacuum. At 60 Hz, maximum pumping speed reaches approximately 1.4 cfm, allowing the ME 2 NT to support medium-throughput filtration equipment and multiple vacuum connections more effectively than lower-capacity pumps.
This makes the ME 2 NT particularly useful for laboratories operating filtration manifolds, several vacuum flasks, aspiration systems, or other parallel low-vacuum applications from a single pump.
Unlike water aspirators, the ME 2 NT consumes no continuous laboratory water and produces no contaminated wastewater simply to generate vacuum. Unlike oil-sealed rotary vane pumps, it requires no vacuum oil, eliminating oil changes, oil mist, and potential oil backstreaming.
VACUUBRAND also emphasizes the ME 2 NT's quiet operation, low vibration, long diaphragm life, and maintenance-free drive system, making it well suited for continuous use in occupied laboratory environments.

Energy Efficiency & Operating Costs
The VACUUBRAND ME 2 NT uses a 180-watt motor and completely oil-free pumping mechanism, making it an economical vacuum source for routine laboratory applications.
Because the pump does not require operating oil, laboratories eliminate oil changes, oil disposal, oil mist, and the possibility of oil backstreaming. This can substantially simplify routine ownership compared with an oil-sealed rotary vane pump when deep vacuum is unnecessary.
The ME 2 NT also provides an alternative to water-driven aspirators. Water aspirators can consume considerable quantities of potable water during continuous operation and may generate contaminated wastewater when process vapors are entrained in the water stream. An electric diaphragm pump provides repeatable vacuum without continuous water consumption.
The maintenance-free drive and long-life diaphragm system further help reduce lifetime service costs.
Specifications compiled from current VACUUBRAND manufacturer literature and American Instrument Exchange product information.
Common Applications
The VACUUBRAND ME 2 NT is particularly well suited for vacuum filtration, membrane filtration, multi-port vacuum manifolds, solid-phase extraction, vacuum ovens, aspiration, degassing, oil-free evacuation, and continuous pumping of compatible gases and vapors.
Its relatively high pumping speed makes the ME 2 NT particularly attractive when several low-vacuum applications need to operate simultaneously.
Ideal Laboratory Types
The ME 2 NT is an excellent choice for analytical chemistry laboratories, microbiology laboratories, biotechnology companies, pharmaceutical quality-control facilities, environmental testing laboratories, wastewater laboratories, food and beverage testing facilities, university research laboratories, educational laboratories, and industrial quality-control departments.
It is especially useful for facilities that want to supply several filtration or sample-preparation stations from a single compact vacuum pump.
Medium-Throughput Vacuum Filtration
Vacuum filtration is one of the strongest applications for the ME 2 NT.
The 1.4 cfm pumping speed at 60 Hz provides substantially more capacity than the smaller ME 1, allowing the pump to evacuate filtration flasks more quickly and better support medium-throughput workflows.
Typical filtration applications may include:
-
Buchner funnel filtration
-
Membrane filtration
-
Microbiological filtration
-
Environmental sample filtration
-
Wastewater analysis
-
Pharmaceutical sample preparation
-
Food and beverage testing
-
General analytical filtration
For laboratories performing multiple filtrations throughout the workday, the ME 2 NT provides an efficient alternative to individual water aspirators or multiple smaller pumps.
Multi-Port Vacuum Manifolds & Parallel Applications
VACUUBRAND specifically identifies multi-port manifolds and parallel laboratory applications as important uses for the ME 2 NT.
Its higher pumping capacity allows one pump to support several compatible low-vacuum processes simultaneously when connected through a properly designed vacuum manifold.
This can be useful for laboratories with:
-
Multiple filtration positions
-
Vacuum aspiration stations
-
Solid-phase extraction manifolds
-
Sample-preparation workstations
-
Educational laboratory benches
-
Multiple vacuum flasks
Actual performance at each connection depends on tubing size, manifold design, gas load, leaks, and the number of applications operating simultaneously.
ME 2 NT for Vacuum Ovens
VACUUBRAND also identifies vacuum ovens as a typical application for the ME 2 NT.
Reducing chamber pressure lowers the boiling temperature of moisture and other volatile substances, helping accelerate drying at lower temperatures.
The ME 2 NT is best suited for vacuum ovens requiring moderate vacuum rather than deep vacuum. Before selecting the pump for a particular oven, users should verify the oven manufacturer's required ultimate pressure, chamber volume, pumping-speed requirement, and expected vapor load.
For vacuum ovens requiring much lower pressures, a two-stage diaphragm or rotary vane pump may be more appropriate.
Oil-Free Vacuum Technology
The ME 2 NT uses an oil-free diaphragm pumping mechanism, providing several practical advantages over oil-sealed vacuum pumps for routine low-vacuum work.
Because there is no pump oil:
-
No routine oil changes are required
-
No contaminated vacuum oil must be disposed of
-
Oil mist is eliminated
-
Oil cannot backstream into laboratory apparatus
-
Solvent or moisture cannot contaminate an oil reservoir
-
Routine maintenance is simplified
For filtration, aspiration, and general laboratory evacuation, these benefits can make diaphragm technology substantially easier to own and operate.
ME 2 NT vs. ME 1 – Which VACUUBRAND Pump Should You Choose?
The ME 1 and ME 2 NT are both oil-free general-purpose diaphragm pumps, but the ME 2 NT offers substantially greater pumping capacity.
The ME 1 provides approximately 0.5 cfm at 60 Hz and reaches an ultimate vacuum of approximately 100 mbar. It is an excellent choice for individual filtration stations and straightforward sample-preparation applications.
The ME 2 NT provides approximately 1.4 cfm at 60 Hz and reaches 70 mbar, giving it nearly three times the pumping speed along with somewhat deeper vacuum.
For one filtration flask or a single user, the ME 1 may be sufficient. For medium-throughput filtration, multi-port manifolds, or several parallel applications, the ME 2 NT provides a significant performance advantage.
ME 2 NT vs. ME 1C
The ME 1C is optimized for chemical resistance, while the ME 2 NT is optimized more strongly around general-purpose pumping capacity.
The ME 1C incorporates chemically resistant wetted components and is a strong choice for filtration and moderate-vacuum applications where aggressive chemical vapors may be encountered.
The standard ME 2 NT is intended for compatible non-corrosive gases and vapors and provides substantially greater pumping speed.
For chemically aggressive processes, laboratories should consider an appropriate VACUUBRAND chemistry diaphragm model rather than selecting solely on pumping speed.
ME 2 NT vs. ME 2C NT
The ME 2 NT and ME 2C NT occupy similar pumping-capacity ranges, but the ME 2C NT is specifically engineered as a chemistry-resistant diaphragm pump.
The ME 2 NT is an excellent choice for general filtration, manifolds, vacuum ovens, aspiration, and oil-free evacuation involving compatible gases and vapors.
The ME 2C NT should be considered when the pump will routinely encounter aggressive solvent or chemical vapors.
This distinction is important: laboratories should select chemical resistance based on the actual substances being processed rather than assuming every diaphragm pump has the same vapor compatibility.
ME 2 NT vs. MZ 2 NT
The ME 2 NT prioritizes pumping speed at moderate vacuum, while an MZ-series pump uses multiple pumping stages to achieve substantially deeper ultimate pressure.
The ME 2 NT reaches 70 mbar and is particularly strong for filtration, manifolds, aspiration, and other low-vacuum applications.
An MZ 2 NT-type platform reaches approximately 7 mbar, making it better suited for processes requiring deeper vacuum such as evaporation or concentration.
Choosing between the two should therefore depend primarily on the required pressure range, not simply pump size.
Recommended Laboratory Applications
The VACUUBRAND ME 2 NT is recommended for:
-
Medium-throughput vacuum filtration
-
Membrane filtration
-
Buchner funnel filtration
-
Multi-port vacuum manifolds
-
Solid-phase extraction
-
Laboratory aspiration
-
Compatible vacuum ovens
-
Degassing
-
Oil-free evacuation
-
Gas transfer
-
Multiple parallel vacuum applications
-
Environmental sample preparation
-
Wastewater testing
-
Microbiology workflows
-
General laboratory vacuum
Application suitability should always be evaluated according to required pressure, gas load, chemical compatibility, tubing configuration, and process conditions.
Why Choose the ME 2 NT Instead of a Water Aspirator?
Water aspirators generate vacuum by continuously passing water through a venturi. Although simple, they consume potable water whenever they operate, and their ultimate vacuum can vary with water temperature and supply pressure.
The ME 2 NT provides a consistent electrically driven vacuum source without continuous water consumption.
It also eliminates contaminated wastewater generated when laboratory vapors become entrained in aspirator water. For laboratories operating filtration or aspiration systems frequently, this can provide meaningful environmental and workflow benefits.
Quiet Operation for Occupied Laboratories
VACUUBRAND specifies a sound pressure level of approximately 45 dBA for the ME 2 NT.
This low operating noise, combined with very low vibration, makes the pump particularly suitable for laboratories where vacuum equipment operates close to researchers throughout the workday.
Quiet operation becomes especially important when one pump serves multiple manifold positions and may remain running for extended periods.
Optional Vacuum Regulation
VACUUBRAND offers an optional manual regulator valve with analog vacuum gauge for ME / MZ / MD 4 / NT pumps.
Adding a regulator allows users to adjust effective vacuum rather than operating every process at maximum pump capacity.
This can be useful for filtration, aspiration, and other laboratory procedures where full pump vacuum is unnecessary.
