Vacuubrand® MZ 2C NT + AK SYNCHRO + EK Chemical Vacuum System

Overview

The Vacuubrand® MZ 2C NT + AK SYNCHRO + EK is a fully integrated, oil-free chemical vacuum system engineered for precision-controlled, corrosion-resistant operation in demanding laboratory environments. Based on dual-stage diaphragm pump technology, it delivers stable vacuum generation across a wide operating range—from rough vacuum (up to 2.0 m³/h at 50 Hz) down to an ultimate absolute pressure of 7 mbar without gas ballast, and 12 mbar when gas ballast is engaged for vapor-laden applications. Its chemically inert PTFE/FFKM diaphragm and valve materials ensure long-term compatibility with aggressive solvents including acetone, dichloromethane, ethyl acetate, and concentrated acids or bases. Designed for simultaneous dual-application use—such as concurrent rotary evaporation and vacuum drying—the system incorporates independent manual flow control valves at each inlet, enabling precise regulation of effective suction speed per process line while maintaining operational isolation via integrated check valves.

Key Features

• Dual independent vacuum inlets with calibrated manual flow control valves for real-time adjustment of suction speed per application
• Integrated glass inlet separator (AK) with protective polymer coating—prevents particulate ingress and liquid carryover into the pump head
• Compact, high-efficiency exhaust condenser (EK) with optimized surface-area-to-volume ratio, achieving >95% solvent recovery under typical rotary evaporation conditions (e.g., ethanol, toluene, THF)
• Gas ballast valve for continuous operation during high-vapor-load processes—maintains stable ultimate vacuum and prevents internal condensation buildup
• Robust aluminum housing with IP 40 protection; vibration-damped mounting and low-noise operation (45 dBA at 50 Hz) suitable for shared lab spaces
• Pre-assembled and factory-tested configuration—ready for immediate deployment with no additional calibration or alignment required

Sample Compatibility & Compliance

The MZ 2C NT + AK SYNCHRO + EK is validated for continuous duty with vapors generated from common organic solvents, aqueous acid/base solutions, and halogenated compounds encountered in synthetic chemistry, natural product isolation, and pharmaceutical QC workflows. Its construction complies with ISO 8573-1:2010 Class 0 (oil-free air) requirements and meets material compatibility standards outlined in ASTM D471 for elastomer resistance. Electrical safety certification includes NRTL listing for both U.S. (UL 61010-1) and Canadian (CAN/CSA-C22.2 No. 61010-1) markets. For ATEX-regulated zones, the 230 V version carries II 3G IIC T3 X classification for use in potentially explosive atmospheres containing Group IIC gases (e.g., hydrogen, acetylene), limited to internal atmospheric conditions only.

Software & Data Management

This system operates as a standalone analog vacuum source and does not include digital control interfaces or embedded software. All operational parameters—including inlet flow rate, condensate volume, and pump runtime—are monitored manually using optional accessories such as the NT SYNCHRO series pressure gauge kit (P/N 699907). When deployed in GLP- or GMP-compliant laboratories, users may integrate external data loggers compatible with 4–20 mA or 0–10 V analog outputs (available via optional pressure transducer add-ons) to support audit trails per FDA 21 CFR Part 11 requirements. Vacuum rubber tubing (DN 8 mm, P/N 686001) and cooling loop connections are provided to facilitate closed-loop solvent recovery setups aligned with ISO 14001 environmental management frameworks.

Applications

• Simultaneous operation of rotary evaporators and vacuum concentrators under controlled, chemically resistant conditions
• Primary vacuum source for freeze dryers and vacuum desiccators requiring non-contaminating, oil-free aspiration
• Solvent removal in peptide synthesis, oligonucleotide purification, and small-molecule crystallization workflows
• Support vacuum filtration of corrosive filtrates (e.g., HF-based etchants, piranha solution residuals) when paired with appropriate trap configurations
• Environmental sample preparation where solvent recovery and emission minimization are mandated by institutional sustainability policies

FAQ

Can this system be used with water aspirators or refrigerated condensers?
Yes—the dual cooling ports (DN 6–8 mm) support connection to external chilled water or glycol loops, enhancing condenser efficiency for high-boiling-point solvents like DMF or DMSO.
Is the AK separator autoclavable?
No—the borosilicate glass AK unit is coated with a protective polymer film and is not rated for autoclaving; cleaning is recommended with appropriate solvent rinses followed by nitrogen purge.
What maintenance intervals are recommended for routine operation?
Diaphragm and valve kits should be inspected every 6 months under continuous use; replacement is typically required every 12–18 months depending on solvent load and duty cycle.
Does the EK condenser require periodic cleaning?
Yes—condensate residue accumulation reduces thermal transfer efficiency; quarterly disassembly and ultrasonic cleaning in isopropanol is advised for optimal recovery performance.
Can the system be mounted vertically or in a fume hood?
It is designed for benchtop horizontal installation only; vertical orientation compromises diaphragm seal integrity and condensate drainage—fume hood placement is permissible if airflow does not exceed 0.5 m/s at the intake.
