Overview
The MKN MM-2 Microplate Oscillator is a precision-engineered orbital shaker designed specifically for low-volume, high-sensitivity life science workflows. It operates on the principle of controlled orbital motion—generating consistent, uniform agitation across 96-well and 384-well microplates, PCR tubes, Eppendorf tubes, and other small-format sample vessels. Unlike general-purpose benchtop shakers, the MM-2 features optimized amplitude and speed regulation to ensure reproducible mixing without splashing, foaming, or cross-contamination—critical for immunoassays, serological testing (e.g., passive hemagglutination, complement fixation), latex agglutination, coagulation assays, and ELISA-based protocols. Its compact footprint and quiet brushless DC motor make it suitable for laminar flow hoods, biosafety cabinets, and shared core lab environments where space and acoustic performance are constrained.
Key Features
- Orbital shaking platform with adjustable speed (0–2000 rpm) and digital timer (0–60 minutes), enabling precise protocol replication across shifts and users.
- Brushless DC motor delivering stable rotational output with minimal thermal drift and long service life—engineered for continuous operation in QC and clinical laboratory settings.
- Universal microplate clamp system accommodating standard ANSI/SLAS-compliant plates (96-well, 384-well), deep-well plates, PCR strips, and conical microcentrifuge tubes (0.2–2.0 mL).
- Integrated safety mechanisms including automatic shutdown upon lid opening, overload protection, and anti-slip silicone matting to prevent plate displacement during high-speed operation.
- Compact, stackable design (W × D × H: 260 × 240 × 140 mm) with IP20-rated enclosure—compliant with IEC 61010-1 for laboratory electrical safety.
Sample Compatibility & Compliance
The MM-2 supports a broad range of biological and diagnostic sample types—including whole blood, serum, plasma, bacterial suspensions, viral lysates, antibody-antigen mixtures, and cell culture supernatants—without compromising assay integrity. It meets essential operational requirements for CLIA-waived and moderate-complexity testing environments. While not certified for ISO 13485 manufacturing, the device is built to align with GLP documentation practices and supports traceable parameter logging when integrated with external data capture systems. Its electrical design conforms to IEC 61010-1:2010 (Edition 3) for measurement, control, and laboratory equipment safety. For regulatory workflows requiring audit trails, users may pair the MM-2 with LIMS-compatible environmental monitoring tools to satisfy FDA 21 CFR Part 11 data integrity expectations at the instrument interface level.
Software & Data Management
The MM-2 operates via an intuitive front-panel interface with LED display and tactile membrane keys—no proprietary software or driver installation required. All operational parameters (speed, time, run status) are retained in non-volatile memory across power cycles. Though standalone by design, the unit’s analog signal outputs (optional via OEM configuration) can be interfaced with programmable logic controllers (PLCs) or SCADA systems for centralized lab automation. For laboratories implementing electronic lab notebooks (ELNs), the MM-2’s repeatable mechanical performance enables robust SOP adherence; its timer and speed settings may be embedded directly into validated assay protocols under ISO/IEC 17025 or CAP-accredited quality systems.
Applications
- Clinical diagnostics: Coagulation time assays (PT, APTT), rheumatoid factor detection, CRP quantification, and infectious disease serology (e.g., HIV, HBV, syphilis screening).
- Immunology research: Antigen-antibody binding kinetics, immune complex formation studies, and complement activation assays.
- Virology & microbiology: Viral titration (TCID50, plaque assays), bacterial suspension homogenization, and phage adsorption optimization.
- Drug discovery: High-throughput screening (HTS) plate conditioning prior to reader analysis, compound solubilization, and bead-based immunoassays (e.g., Luminex xMAP).
- Quality control: Reagent reconstitution verification, lot-to-lot consistency checks, and stability-indicating mixing validation per USP and .
FAQ
What plate formats does the MM-2 support?
Standard 96-well and 384-well microplates (flat, V-bottom, U-bottom), PCR plates, and individual microcentrifuge tubes (0.2–2.0 mL) with optional tube adapters.
Is the MM-2 compatible with cold rooms or refrigerated incubators?
Yes—the unit operates reliably within ambient temperatures of 5–40 °C and relative humidity ≤80% non-condensing, making it suitable for use inside chilled chambers when mounted on vibration-dampened surfaces.
Does the MM-2 meet electromagnetic compatibility (EMC) standards?
It complies with EN 61326-1:2013 for laboratory equipment EMC requirements, including radiated and conducted emissions limits per CISPR 11.
Can speed and time settings be locked to prevent accidental changes?
Yes—parameter lock mode is activated via a two-second keypress sequence, preventing unauthorized modification during unattended runs.
What maintenance is required for long-term reliability?
No routine lubrication is needed; periodic cleaning of the platform surface and inspection of the clamping mechanism every 6 months is recommended per manufacturer guidelines.
