Overview
The Chengmeng CM200 Multi-Tube Vortex Mixer is an engineered solution for high-throughput sample homogenization in clinical diagnostics, pharmaceutical quality control, molecular biology, and environmental testing laboratories. It operates on the principle of horizontal orbital motion—generating consistent, low-shear orbital oscillation to induce turbulent mixing within tubes without compromising sample integrity. Unlike single-tube vortexers, the CM200 accommodates multiple sample vessels simultaneously on a rigid, balanced platform, enabling parallel processing of up to 24 standard 15 mL or 50 mL conical tubes (configuration-dependent), significantly improving workflow efficiency while maintaining mechanical reproducibility across all positions. Its 4 mm orbital amplitude ensures effective suspension of particulates and reconstitution of lyophilized reagents, particularly suited for viscous buffers, cell suspensions, and immunoassay reagents.
Key Features
- Stable horizontal orbital drive mechanism with brushless DC motor for long-term operational consistency and minimal thermal drift
- Digital LED speed and timer interface with real-time rpm feedback and programmable countdown function (1 min to 99 h 59 min)
- Robust powder-coated steel housing and reinforced platform structure supporting up to 4.5 kg total load
- Adjustable speed range (500–2500 rpm) calibrated to ±2% accuracy across full scale, traceable to internal reference standards
- Low-noise operation (<55 dB(A) at 1 m) suitable for shared laboratory environments and ISO Class 5–8 cleanroom-adjacent workspaces
- Overheat protection circuitry and automatic shutdown upon abnormal load detection or extended runtime failure
Sample Compatibility & Compliance
The CM200 supports a broad range of tube formats—including polypropylene, glass, and PCR-grade plastic tubes (1.5 mL to 50 mL)—via interchangeable adapter plates (sold separately). Its uniform orbital motion minimizes tube tipping and foaming, critical for sensitive applications such as ELISA plate prep, genomic DNA extraction workflows, and residual solvent dispersion in HPLC sample vials. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EMC requirements per EN 61326-1:2013. While not certified for GMP manufacturing environments, its design supports GLP-aligned documentation practices, including user-defined protocol logging (when integrated with optional RS-232/USB data export) and audit-ready operation records.
Software & Data Management
The CM200 operates as a standalone instrument with no embedded firmware-based software. However, it features an RS-232 serial port (standard) and optional USB-to-serial adapter support for integration into laboratory information management systems (LIMS) or electronic lab notebooks (ELN). Through simple ASCII command protocols, users can remotely initiate, pause, or query current speed/timer status—enabling traceability in regulated environments. When paired with validated third-party automation middleware, the mixer supports 21 CFR Part 11-compliant electronic signatures and audit trails for critical mixing steps in QC release testing.
Applications
- Routine homogenization of blood serum, urine, and saliva samples prior to centrifugation or immunoassay analysis
- Re-suspension of bacterial pellets and yeast cultures in microbiology workflows
- Preparation of calibration standards and QC reference materials across clinical chemistry and toxicology labs
- Mixing of magnetic bead suspensions in automated nucleic acid purification platforms
- Dispersion of nanoparticle colloids and polymer emulsions in materials science R&D
FAQ
Is the CM200 suitable for use with microcentrifuge tubes (0.2–2.0 mL)?
Yes—when used with the optional 24-position microtube adapter plate, the CM200 achieves uniform mixing of 0.2 mL PCR strips and 1.5 mL Eppendorf-style tubes without leakage or cross-contamination.
Does the unit include vibration isolation feet?
Standard configuration includes non-slip rubber feet; optional anti-vibration gel mounts are available for installation on sensitive analytical benches (e.g., adjacent to balances or spectrophotometers).
Can speed and time settings be locked to prevent accidental changes during routine operation?
Yes—the front panel keypad supports password-protected parameter lock mode, configurable via three-digit access code to restrict unauthorized adjustments in shared lab settings.
What maintenance is required for long-term reliability?
No scheduled lubrication or calibration is needed; periodic cleaning of the platform surface and inspection of adapter plate retention clips are recommended every 6 months under continuous use.
Is CE marking applied to this model?
The CM200 carries CE marking under the Low Voltage Directive (2014/35/EU) and EMC Directive (2014/30/EU), with technical documentation available upon request for EU-based purchasers.
