Overview
The DLAB BlueSpin MS-H280-Pro is a precision-engineered heating magnetic stirrer designed for reproducible, safe, and controllable mixing in research laboratories, quality control environments, and routine analytical workflows. It operates on the principle of rotating magnetic fields generated by a permanent magnet array beneath a thermally stable ceramic-coated aluminum hotplate, inducing synchronized rotation of PTFE- or glass-coated stir bars immersed in liquid samples. Integrated resistive heating elements enable uniform thermal distribution across the 135 mm diameter plate surface, while dual independent LED displays provide real-time monitoring of both setpoint and actual values for temperature and rotational speed—critical for method adherence in regulated settings.
Key Features
- Dual Independent LED Displays: Simultaneous readout of target and actual temperature (±1 °C resolution) and speed (100–1500 rpm), enabling immediate verification of operational parameters without menu navigation.
- Multi-Layer Thermal Safety Architecture: Includes an independent hardware-based overtemperature cutoff at 320 °C, residual heat warning activation above 50 °C (even after power-off but with mains connected), and flame-retardant housing certified to DIN/EN 60529 IP21 standards.
- Enhanced Temperature Control Options: Supports both internal plate-sensor regulation (±1 °C 100 °C) and external PT1000 probe feedback for direct sample temperature control (±0.5 °C), minimizing thermal lag and improving process fidelity.
- Robust Mechanical Design: Brushless DC motor delivers consistent torque across the full speed range with low electromagnetic interference and minimal maintenance requirements. The enamel-coated aluminum plate ensures chemical resistance and long-term thermal stability.
- Regulatory-Ready Compliance: Certified to CE, cTUVus (UL/CSA), and FCC standards—meeting essential safety and electromagnetic compatibility requirements for deployment in ISO/IEC 17025-accredited labs and facilities operating under GLP or GMP frameworks.
Sample Compatibility & Compliance
The MS-H280-Pro accommodates standard laboratory vessels up to 3 L volume (water-equivalent), including beakers, flasks, and reaction vials. Its 135 mm hotplate supports common vessel footprints while maintaining optimal magnetic coupling for stir bars up to 50 mm in length. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and satisfies environmental operating constraints per IEC 60721-3-3 (Class 3K3: 5–40 °C, ≤80% RH non-condensing). Flame-retardant enclosure materials meet UL 94 V-0 equivalency as verified under DIN/EN 60529 IP21 ingress protection testing.
Software & Data Management
While the MS-H280-Pro operates as a standalone instrument without embedded data logging, its RS232 interface (though not enabled by default firmware) provides a physical pathway for future integration into centralized lab management systems via optional serial-to-USB adapters and third-party SCADA or LIMS middleware. All parameter settings—including temperature setpoints, speed profiles, and safety thresholds—are retained in non-volatile memory during power cycles. Audit-ready operation is supported through manual logbook entries aligned with FDA 21 CFR Part 11 principles when used in conjunction with validated procedural documentation and operator training records.
Applications
- Precipitation and crystallization studies requiring precise thermal ramping and agitation synchronization
- Solution preparation for HPLC mobile phases, buffer stocks, and calibration standards
- Heating-assisted dissolution testing in pharmaceutical development (aligned with USP & Ph. Eur. general chapters)
- Controlled polymerization initiation and viscosity monitoring in material science labs
- Cell culture media warming and reagent equilibration prior to sterile processing
- Environmental sample digestion protocols where closed-vessel heating and stirring are employed
FAQ
Does the MS-H280-Pro support programmable temperature ramps or multi-step protocols?
No—the device features fixed-setpoint control only. For time-dependent thermal profiles, external programmable controllers or integrated lab automation platforms must be used.
Can the PT1000 sensor be calibrated independently of the unit’s internal reference?
Yes; the external sensor input accepts factory-traceable PT1000 probes, and calibration verification can be performed using NIST-traceable reference thermometers per ASTM E74 or ISO/IEC 17025 procedures.
Is the unit suitable for use inside a fume hood?
Yes—its IP21 rating and absence of moving ventilation components permit safe operation in ventilated enclosures, provided ambient humidity remains within specified limits and airflow does not impede heat dissipation from the base unit.
What maintenance is required to ensure long-term accuracy?
Annual verification of temperature and speed accuracy using traceable metrology tools is recommended. Cleaning should be limited to dry lint-free cloths; solvents or abrasives may degrade the enamel coating or display overlay.
