SCILOGEX MS-H-Pro+ Digital Heating Magnetic Stirrer

Overview

The SCILOGEX MS-H-Pro+ Digital Heating Magnetic Stirrer is an engineered solution for precise, reproducible, and thermally stable mixing in research laboratories, quality control environments, and industrial R&D settings. Based on electromagnetic induction coupling between the internal drive magnet and a rotating stir bar placed within the sample vessel, this instrument delivers consistent torque transmission without mechanical contact—eliminating wear, contamination risk, and maintenance overhead. Its integrated PID-controlled heating system enables rapid thermal ramping and high-fidelity temperature regulation up to 340 °C, making it suitable for demanding applications such as polymer dissolution, catalyst activation, high-boiling-point solvent reactions, and extended thermal stability studies. Designed for continuous-duty operation under load, the MS-H-Pro+ maintains stable rotational performance even at maximum speed (1500 rpm) and peak temperature, validated through accelerated life testing exceeding 600 hours at 340 °C.

Key Features

• Brushless DC motor architecture ensures low-noise, low-vibration operation with extended service life and consistent torque delivery across the full 100–1500 rpm range
• Ceramic-coated stainless steel heating plate (Ø135 mm) provides uniform thermal distribution, resistance to acid/base corrosion, and easy surface decontamination
• PID-based digital temperature control with dual-sensing capability: onboard thermistor for plate monitoring and optional external PT1000 probe for direct sample temperature feedback (±0.2 °C accuracy)
• Backlit LCD display simultaneously shows real-time speed (±1 rpm resolution) and temperature (±0.1 °C resolution), supporting intuitive parameter verification during operation
• RS232 serial interface enables bidirectional communication with Windows-based PCs using the included StirPC software for remote control, automated protocol execution, and timestamped data logging of speed and temperature trajectories
• Robust aluminum housing with electrostatically applied chemical-resistant coating enhances structural integrity and thermal dissipation while meeting IP42 ingress protection standards

Sample Compatibility & Compliance

The MS-H-Pro+ accommodates standard laboratory glassware including beakers, flasks, and reaction vessels up to 20 L capacity (water-equivalent). It supports stir bars up to 80 mm in length and is compatible with chemically resistant PTFE- or glass-coated magnetic agitators. The ceramic-coated plate resists degradation from common organic solvents, mineral acids (e.g., HCl, HNO₃), and alkaline solutions encountered in synthesis, extraction, and buffer preparation workflows. From a regulatory standpoint, the unit carries CE, cTUVus (UL 61010-1), and FCC marks—certifying conformance with IEC 61010-1:2010 for electrical safety in laboratory equipment. Its design aligns with GLP principles through traceable parameter recording (via StirPC), audit-ready data export (CSV format), and stable operational repeatability required for method validation under ISO/IEC 17025 and USP .

Software & Data Management

StirPC, the free companion software provided with the MS-H-Pro+, operates on Windows 7–11 platforms and supports both manual and script-driven control modes. Users can define multi-step protocols—including ramp-hold-cool sequences—with independent setpoints for speed and temperature. All operational parameters are logged at user-selectable intervals (1–60 s), generating time-stamped CSV files compliant with 21 CFR Part 11 requirements when used with appropriate system-level controls (e.g., Windows account authentication, electronic signatures). Data export supports post-acquisition analysis in MATLAB, Python (Pandas), or Excel. The RS232 interface complies with EIA/TIA-232-F specifications, ensuring interoperability with legacy lab automation systems and SCADA environments.

Applications

• Kinetic studies requiring simultaneous temperature ramping and controlled agitation in homogeneous reaction media
• Dissolution testing of pharmaceutical excipients and active ingredients under pharmacopoeial conditions (USP )
• Preparation of nanomaterial dispersions and colloidal suspensions where shear history and thermal history must be tightly controlled
• Heating and stirring of viscous polymer melts prior to rheological characterization or casting
• Standardization of calibration standards in environmental and food testing labs (e.g., heavy metal digestion per EPA Method 3050B)
• Long-duration stability assays involving elevated temperatures and constant mixing to simulate accelerated aging

FAQ

Does the MS-H-Pro+ support external temperature feedback during heating?
Yes—it accepts a standard PT1000 RTD sensor via a dedicated analog input port, enabling closed-loop control based on actual sample temperature rather than plate surface temperature.
Is the RS232 interface optically isolated?
No—the RS232 port is electrically coupled and requires proper grounding in electrically noisy environments; use of an isolated USB-to-RS232 adapter is recommended for industrial installations.
Can the unit maintain 340 °C continuously for more than 24 hours?
Yes—validated by factory endurance testing: units operated unattended at 340 °C and 1500 rpm for 624 consecutive hours showed no deviation in speed stability, temperature accuracy, or thermal cutoff functionality.
What is the maximum allowable ambient humidity for safe operation?
The device is rated for continuous use at ≤80 % relative humidity (non-condensing), in accordance with DIN EN 60529 IP42 classification.
Is StirPC software validated for GxP environments?
StirPC itself is not individually 21 CFR Part 11 validated; however, its audit-trail-capable data export and configurable user access controls allow integration into validated laboratory informatics systems when deployed with documented configuration management and change control procedures.
