VACUUBRAND MZ 1C Chemistry Diaphragm Pump Overview
The VACUUBRAND MZ 1C is designed specifically for laboratory applications where chemical resistance, deeper diaphragm-pump vacuum, and a compact footprint are more important than high pumping speed.
Its two-stage configuration allows the MZ 1C to achieve substantially lower pressure than single-stage filtration pumps. With an ultimate vacuum of 12 mbar / 9 Torr, the pump can support evaporation, evacuation, concentration, and other chemistry workflows that would be beyond the practical operating range of basic diaphragm pumps.
VACUUBRAND constructs the major components exposed to pumped media from chemically resistant fluoroplastics. Proven PTFE sandwich diaphragms provide additional reliability and help extend operating life.
An integrated gas ballast valve further improves the pump's ability to handle condensable vapors by permitting continuous condensate purge.
At only approximately 4.8 inches wide, the MZ 1C also offers a particularly narrow footprint, allowing installation beside laboratory instruments or within crowded chemistry workspaces where bench space is limited.

Energy Efficiency & Operating Costs
The MZ 1C uses a relatively low-power 60-watt motor, making it an economical vacuum source for laboratory workflows that do not require the higher pumping capacity of larger chemistry diaphragm pumps.
Its oil-free diaphragm design eliminates vacuum pump oil purchases, oil changes, contaminated-oil disposal, oil mist, and oil backstreaming. This is particularly advantageous when pumping solvent vapors, which can contaminate and degrade oil in conventional rotary vane vacuum pumps.
VACUUBRAND also uses a maintenance-free drive system and long-life PTFE sandwich diaphragms, helping minimize routine service requirements.
For laboratories that require chemistry-resistant vacuum from a single workstation or relatively small apparatus, the MZ 1C can therefore provide an efficient alternative to operating a larger vacuum pump than the application actually requires.
Common Applications
The VACUUBRAND MZ 1C is particularly well suited for solvent evaporation, chemical-vapor pumping, evacuation, vacuum concentration, degassing, small-scale rotary evaporation, vacuum drying, and other laboratory processes involving corrosive or condensable gases and vapors.
Its combination of chemical resistance, 12 mbar ultimate vacuum, and compact dimensions makes it particularly useful for individual chemistry workstations and smaller-scale laboratory processes.
Ideal Laboratory Types
The MZ 1C is an excellent choice for pharmaceutical research laboratories, medicinal chemistry groups, biotechnology companies, analytical chemistry facilities, organic chemistry laboratories, university research groups, contract research organizations, quality-control laboratories, environmental laboratories, and industrial R&D facilities.
It is particularly attractive for laboratories that need a dedicated chemistry-resistant vacuum pump for one instrument or workstation rather than a larger central vacuum source.
Chemical Resistance & Corrosive Vapor Handling
Chemical resistance is a defining feature of the MZ 1C.
VACUUBRAND manufactures the major components in contact with pumped media from chemically resistant fluoroplastics. The pump also incorporates proven PTFE sandwich diaphragms designed to improve reliability and extend operating life.
This construction allows the MZ 1C to continuously pump many corrosive gases and solvent vapors without exposing a reservoir of vacuum pump oil to those chemicals.
That distinction makes the MZ 1C considerably better suited for chemistry applications than a standard general-purpose diaphragm pump when aggressive vapors are expected.
Chemical compatibility should always be confirmed for the specific substances, concentrations, temperatures, and operating conditions involved.
Two-Stage Vacuum Performance
The MZ 1C uses two diaphragm heads arranged in two pumping stages.
This configuration allows the pump to reach an ultimate pressure of 12 mbar / 9 Torr, substantially deeper than the approximately 100 mbar range typical of many basic single-stage filtration pumps.
The lower ultimate pressure expands the MZ 1C's usefulness beyond simple filtration and aspiration into evaporation, concentration, drying, and evacuation applications.
For laboratories that need still deeper vacuum or substantially greater pumping speed, the larger MZ 2C NT provides the next logical step within the VACUUBRAND chemistry diaphragm family.
Gas Ballast & Condensable Vapor Handling
The MZ 1C includes an integrated gas ballast valve for continuous condensate purge.
Condensable vapor can accumulate within a vacuum pump when vapor pressure and pump temperature cause material to condense during compression. Gas ballast helps reduce this effect and improves the pump's ability to handle condensable vapor loads.
With gas ballast closed, the MZ 1C reaches approximately 12 mbar / 9 Torr. With gas ballast operating, VACUUBRAND specifies an ultimate vacuum of approximately 20 mbar / 15 Torr.
Compact Vacuum Pump for Space-Constrained Laboratories
One of the MZ 1C's most distinctive physical characteristics is its narrow design.
The pump measures approximately 12.3" L × 4.8" W × 6.7" H, occupying very little lateral bench space.
This narrow footprint can be particularly useful beside rotary evaporators, vacuum manifolds, laboratory reactors, concentrators, or other equipment where bench space is already crowded.
At approximately 14.8 lb, the pump is also relatively easy to relocate between compatible laboratory workstations when needed.
MZ 1C for Solvent Evaporation
The MZ 1C provides an attractive vacuum source for small-scale solvent evaporation applications requiring chemically resistant, oil-free pumping.
Reducing pressure lowers solvent boiling temperature, allowing evaporation to proceed at lower thermal exposure than would be required at atmospheric pressure.
The pump's 12 mbar ultimate vacuum gives it considerably greater evaporation capability than a basic filtration pump, while the chemistry-resistant construction helps protect the pumping mechanism from many common laboratory vapors.
For processes producing significant condensate, laboratories should also consider appropriate cold traps, inlet separators, or exhaust condensers.
MZ 1C for Small Rotary Evaporators
The MZ 1C can be a useful vacuum source for compatible small-scale rotary evaporators, particularly when modest pumping capacity is sufficient.
Its 12 mbar ultimate vacuum can support evaporation of many common laboratory solvents under reduced pressure, while its narrow footprint minimizes the amount of bench space required beside the evaporator.
Because the standard MZ 1C is a fixed-speed pump without integrated automatic vacuum regulation, an external manual or electronic vacuum-control solution may be appropriate where precise boiling-pressure control is required.
MZ 1C vs. ME 1C
The ME 1C and MZ 1C are both chemically resistant oil-free diaphragm pumps, but they are optimized for different vacuum requirements.
The ME 1C is a single-stage chemistry diaphragm pump designed primarily for filtration, aspiration, and moderate-vacuum applications.
The MZ 1C uses a two-stage pumping arrangement and reaches 12 mbar, providing substantially deeper vacuum for evaporation, concentration, drying, and evacuation.
For filtration and moderate vacuum, the ME 1C may be the more economical choice. For applications requiring lower pressure, the MZ 1C provides a significant performance advantage.
MZ 1C vs. MZ 2C NT
The MZ 1C and MZ 2C NT are both two-stage chemistry diaphragm pumps, but the larger MZ 2C NT provides greater pumping capacity and deeper ultimate vacuum.
The MZ 1C provides approximately 0.5 cfm at 60 Hz and reaches 12 mbar.
The MZ 2C NT provides approximately 1.4 cfm at 60 Hz and reaches 7 mbar.
The MZ 1C is an excellent choice for smaller apparatus, individual chemistry workstations, and applications where compact dimensions are important. The MZ 2C NT is better suited for larger vapor loads, faster evacuation, and applications requiring somewhat deeper vacuum.
MZ 1C vs. ME 2 NT
The ME 2 NT and MZ 1C illustrate the difference between selecting a pump for pumping speed and selecting one for vacuum depth and chemical resistance.
The ME 2 NT provides substantially higher pumping speed at approximately 1.4 cfm but reaches only about 70 mbar and is a general-purpose diaphragm pump.
The MZ 1C provides lower pumping speed but reaches 12 mbar and is specifically engineered for chemically aggressive gases and vapors.
For medium-throughput filtration or multiple parallel applications involving compatible non-corrosive gases, the ME 2 NT may be preferable. For solvent evaporation and chemical-vapor applications requiring deeper vacuum, the MZ 1C is the stronger choice.
Optional Manual Vacuum Regulation
VACUUBRAND offers a manual vacuum regulator valve with dial gauge as an accessory for the MZ 1C.
This allows users to regulate effective pumping speed and vacuum rather than simply operating at the pump's maximum available vacuum.
Manual regulation can be useful for evaporation and other processes where applying maximum vacuum immediately may cause bumping, foaming, or excessive solvent boiling.
For laboratories requiring fully automatic vacuum regulation, a VACUUBRAND VARIO Select system provides more advanced process control.
