Overview
The DLAB MX-RD-Pro LCD Programmable Orbital Rotator Mixer is an engineered solution for gentle, reproducible, and controllable sample agitation in life science and clinical laboratory workflows. Unlike vortex or linear shakers, the MX-RD-Pro employs orbital rotation—generating a consistent circular motion with adjustable tilt angle—to induce low-shear mixing ideal for delicate biological suspensions. Its design adheres to fundamental principles of fluid dynamics in small-volume containers, ensuring uniform suspension without foaming, phase separation, or cellular damage. The device is optimized for applications requiring sustained, low-intensity agitation over extended durations—such as antibody-antigen binding in immunoassays, anticoagulant-treated blood sample maintenance, and latex agglutination diagnostics—where mechanical integrity and mixing consistency directly impact assay validity.
Key Features
- Programmable orbital rotation with continuously adjustable tilt angle from 0° to 90°, enabling optimization of mixing intensity for diverse tube geometries and viscosities.
- High-resolution backlit LCD display simultaneously shows real-time rotational speed (rpm) and remaining timer duration—critical for GLP-compliant documentation and protocol adherence.
- Brushless DC motor architecture ensures >20,000 hours of operational lifetime, zero carbon dust generation, and stable torque delivery across the full 10–70 rpm range—even under load variation from multi-tiered disk configurations.
- Modular disc platform supports up to four stacked rotating levels using standardized DLAB-compatible clamping accessories (e.g., 1.5/2.0 mL tube holders, PCR strip carriers, microplate adapters), maximizing throughput without cross-contamination risk.
- Universal input power supply (100–240 V AC, 50/60 Hz) enables seamless deployment across global laboratory infrastructures; IP21-rated enclosure provides protection against vertically falling drips and solid objects ≥12.5 mm.
- Two operational modes—continuous run and programmable timer (1–1199 minutes)—support both routine maintenance tasks and time-critical incubation-mixing protocols.
Sample Compatibility & Compliance
The MX-RD-Pro accommodates standard laboratory consumables including Eppendorf-style tubes (1.5–50 mL), microcentrifuge tubes, diagnostic latex reagent vials, and shallow-well microplates. Its low-speed orbital action preserves cell viability in hematological samples and prevents denaturation of immunoglobulin complexes during precipitation assays. The system complies with IEC 61010-1:2010 for safety in laboratory equipment and meets electromagnetic compatibility requirements per EN 61326-1:2013. While not certified for ISO 13485 or FDA 21 CFR Part 11 out-of-the-box, its deterministic timing logic, non-volatile parameter memory, and unambiguous LCD feedback support audit-ready operation under GLP and internal QA frameworks.
Software & Data Management
The MX-RD-Pro operates via embedded firmware without external software dependency—ensuring reliability, cybersecurity resilience, and minimal IT overhead. All user-defined parameters (speed, angle, duration, mode) are retained in non-volatile memory after power cycling. The LCD interface provides traceable visual confirmation of active settings, satisfying basic data integrity requirements for regulated environments. For laboratories implementing electronic lab notebooks (ELNs) or LIMS integration, optional RS-232 or USB-to-serial adapters (sold separately) enable ASCII command-based remote control and logging of runtime events—including start/stop timestamps and setpoint deviations—facilitating alignment with ALCOA+ data governance principles.
Applications
- Immunoprecipitation workflows requiring prolonged, low-shear antibody–bead interaction.
- Maintenance of anticoagulated whole blood or plasma specimens prior to centrifugation or analysis—preventing fibrin clot formation.
- Latex agglutination assays (e.g., CRP, RF, streptococcal antigen detection) where uniform particle dispersion directly determines endpoint sensitivity.
- Hybridization steps in nucleic acid capture protocols involving magnetic beads or solid-phase membranes.
- Reagent resuspension and buffer equilibration for ELISA kit preparation and QC testing.
- Cell culture maintenance during transient transfection or co-culture experiments where orbital motion minimizes shear stress versus orbital shakers.
FAQ
What is the maximum load capacity per disc level?
Each standard disc supports up to 12 × 1.5 mL tubes or 4 × 15 mL conical tubes; total payload must remain within 1.2 kg per stack to maintain speed stability and bearing longevity.
Can the MX-RD-Pro be used inside a cold room or incubator?
Yes—operational ambient range is 5–40°C at ≤80% RH; however, condensation on the LCD or motor housing must be prevented by acclimatization or sealed enclosures.
Is calibration required or supported?
No factory calibration certificate is provided; users may verify rotational speed using a handheld tachometer traceable to NIST standards—typical deviation is ±1 rpm across the operating range.
Are third-party tube holders compatible?
Only DLAB-certified accessories are guaranteed for mechanical fit, balance, and vibration damping; non-OEM clamps may induce resonance or premature wear.
Does the device support automatic restart after power interruption?
No—the unit resets to default settings (30 rpm, 0°, continuous mode) upon power restoration; programmable timers do not retain state.
