RWD M1324R Micro High-Speed Refrigerated Centrifuge

Overview

The RWD M1324R Micro High-Speed Refrigerated Centrifuge is an engineered benchtop solution designed for precise, reproducible separation of biomolecular samples under thermally controlled conditions. Utilizing fixed-angle rotor architecture and active refrigeration with PID-controlled compressor cooling, the M1324R maintains sample integrity during high-g-force operations—critical for nucleic acid precipitation, protein pelleting, viral particle concentration, and column-based purification workflows. Its operational envelope spans 100–15,000 rpm (up to 21,130 × g), with temperature stabilization from −10 °C to +40 °C, enabling consistent thermal management even at maximum rotational speed. The system’s compact footprint (500 × 300 × 280 mm) and low acoustic signature (<54 dB[A]) make it suitable for shared laboratory environments, biosafety cabinets, and QC/QA labs where spatial efficiency and operator comfort are prioritized.

Key Features

• Thermally stable refrigeration system with rapid pre-cooling: achieves 4 °C chamber temperature from ambient in ≤8 minutes
• Aerospace-grade aluminum alloy fixed-angle rotors—certified for autoclave sterilization (121 °C, 20 min) and validated via ultrasonic non-destructive testing (NDT), Schenck dynamic balancing, and burst pressure testing per ISO 15841
• Real-time rotor imbalance monitoring with multi-stage alarm logic—including audible alert, visual warning, and automatic deceleration upon threshold exceedance
• 4.3″ capacitive touchscreen interface with glove-compatible operation and one-touch parameter locking
• Twelve programmable centrifugation protocols stored locally; supports sequential step programming (e.g., ramp-to-speed → hold → decelerate)
• Magnetic condensate tray for passive collection of refrigerant-induced moisture—eliminates manual draining and prevents drip contamination
• Dual mechanical lid interlock system with positive-latch engagement; quick-lock rotor cover requiring only 60° rotation (1/6 turn) for secure sealing
• High-efficiency insulation using closed-cell polyurethane foam with thermal conductivity ≤0.022 W/m·K, minimizing energy consumption and ambient heat transfer

Sample Compatibility & Compliance

The M1324R accommodates standard microcentrifuge formats including 1.5 mL and 2.0 mL conical tubes, PCR strip tubes (via optional M-F4 rotor), and spin-column cartridges (M-F18Kit rotor). All rotors comply with IEC 61010-1:2010 safety standards for laboratory equipment and meet EN 61326-1 electromagnetic compatibility requirements. The sealed rotor design conforms to ISO 22174:2021 guidelines for containment of biohazardous aerosols during high-speed operation. When operated with validated rotor/load configurations, the system supports GLP-compliant documentation workflows through exportable run logs (timestamped speed, RCF, temperature, duration, rotor ID). While not FDA 21 CFR Part 11–certified out-of-the-box, audit-trail-ready data export enables integration into validated LIMS or ELN platforms supporting electronic records compliance.

Software & Data Management

The embedded firmware provides local storage of all centrifugation events—including start/stop timestamps, user ID (if enabled), rotor serial number, set parameters, and real-time deviation alerts. Run history is exportable via USB 2.0 port in CSV format for traceability and quality review. No cloud connectivity or remote access functionality is implemented, preserving data sovereignty and aligning with institutional IT security policies. Firmware updates are performed offline via encrypted USB stick, with version rollback capability and SHA-256 checksum verification. The UI adheres to WCAG 2.1 AA contrast ratios for readability under varied lab lighting conditions.

Applications

• Routine nucleic acid isolation: plasmid prep, genomic DNA extraction, RNA clean-up following phenol-chloroform or silica-membrane methods
• Protein fractionation: membrane pellet recovery, antibody purification, enzyme assay preparation
• Virology workflows: lentiviral/AAV vector concentration, exosome pelleting (≥100,000 × g equivalent when combined with swing-out adapters in future configurations)
• Diagnostic sample prep: serum/plasma separation from whole blood, pathogen pellet enrichment prior to PCR or sequencing
• QC/QA in biomanufacturing: residual host cell protein removal validation, buffer exchange confirmation

FAQ

What is the minimum and maximum operating temperature range?
The chamber temperature is precisely regulated between −10 °C and +40 °C, with ±0.5 °C stability across the full speed range.
Is rotor calibration required before first use?
No factory calibration is needed; each rotor is supplied with a certified balance report and serial-numbered traceability documentation compliant with ISO/IEC 17025.
Can the M1324R be used for clinical diagnostic applications under CLIA or CAP guidelines?
Yes—when operated with documented SOPs, maintenance logs, and periodic performance verification (e.g., temperature uniformity mapping, speed accuracy checks), it meets core instrumentation requirements for moderate-complexity testing environments.
Does the system support external control via RS-232 or Ethernet?
No. The M1324R operates as a standalone instrument with no network interface; all control and data export occur via front-panel interface or USB.
What safety certifications does the M1324R hold?
It carries CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), and complies with GB 4793.1–2019 (China’s national standard equivalent to IEC 61010-1).
