Overview
The DLAB MS10-H500-Pro is a high-performance, microprocessor-controlled hotplate magnetic stirrer engineered for demanding laboratory environments requiring simultaneous precise heating and robust mixing of large-volume samples. It operates on the principle of electromagnetic induction: a rotating magnetic field generated beneath the ceramic glass top drives magnetic stir bars immersed in conductive or low-viscosity liquids. Unlike convection-based heating systems, this design ensures direct, uniform thermal transfer to the vessel base while minimizing ambient heat loss and enabling stable temperature maintenance across extended durations. Designed for routine QC/QA workflows, method development in analytical chemistry, and preparative-scale synthesis, the MS10-H500-Pro supports reproducible process conditions under GLP-compliant documentation protocols—particularly where traceability of thermal and rotational parameters is essential.
Key Features
- 10-inch square ceramic glass heating surface (250 × 250 mm), rated for continuous operation up to 500 °C and resistant to thermal shock, strong acids, alkalis, and organic solvents.
- High-torque drive system delivering consistent agitation at speeds from 100 to 1500 rpm with ±1 rpm repeatability—optimized for viscous solutions, suspensions, and heterogeneous reaction mixtures.
- Dual-sensor temperature control architecture: integrated surface thermistor for plate monitoring + optional external PT1000 probe input for direct sample temperature feedback, achieving ±0.2 °C accuracy in closed-loop mode.
- Backlit LCD interface displaying real-time setpoint and measured values for both temperature and speed, with intuitive rotary encoder navigation and tactile button controls.
- Programmable timer (0–99 h 59 min) enabling unattended operation; automatic shutdown upon completion or thermal fault detection.
- Residual heat warning system: LED indicator flashes continuously until the ceramic plate cools below 50 °C post-shutdown, reducing burn risk during equipment handling.
- Onboard SD card slot supporting FAT32-formatted cards (up to 32 GB) for time-stamped logging of temperature, speed, and operational status at user-defined intervals (1–60 s).
Sample Compatibility & Compliance
The MS10-H500-Pro accommodates standard laboratory vessels—including borosilicate glass beakers (up to 5 L), stainless steel reactors, and PTFE-coated containers—within its 250 mm × 250 mm active zone. Its flat, non-porous ceramic surface ensures compatibility with aggressive reagents commonly used in wet digestion (e.g., HNO₃/HF mixtures), catalyst preparation, and polymerization studies. The instrument complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets EMC requirements per EN 61326-1:2013. When configured with PT1000 feedback and SD logging, it supports audit-ready data integrity aligned with FDA 21 CFR Part 11 principles (electronic records and signatures), provided institutional validation protocols are applied.
Software & Data Management
No proprietary software installation is required. Raw log files (.CSV format) written to the SD card are compatible with standard spreadsheet applications (Microsoft Excel, LibreOffice Calc) and LIMS integration via automated file ingestion scripts. Each record includes timestamp (YYYY-MM-DD HH:MM:SS), set temperature (°C), actual plate temperature (°C), actual sample temperature (°C, if PT1000 connected), set speed (rpm), actual speed (rpm), and operational state (ON/OFF/ALARM). Timestamp resolution is synchronized to the internal RTC (real-time clock) with ±2 seconds/month drift. Data export does not require driver installation or vendor-specific utilities—enabling seamless cross-platform analysis and long-term archival.
Applications
- Heating and homogenizing large-volume buffers and media (e.g., 20–30 L phosphate-buffered saline or nutrient broth) prior to sterilization or filtration.
- Controlled-temperature dissolution testing per USP and ASTM D2765 for pharmaceutical excipients and polymer matrices.
- Preparative-scale catalytic reactions requiring inert-atmosphere compatibility (when used with sealed vessels and magnetic coupling).
- Standardization of calibration standards in environmental labs (e.g., heavy metal stock solutions, EPA Method 200.7 digestions).
- Accelerated stability studies under isothermal conditions (40 °C/75% RH preconditioning support) where mechanical agitation prevents sedimentation-induced concentration gradients.
FAQ
Is the MS10-H500-Pro suitable for use with flammable solvents?
Yes, when operated below the autoignition temperature of the solvent and in well-ventilated or fume-hood environments. The ceramic surface eliminates sparking risks associated with metal hotplates.
Can the external PT1000 sensor be calibrated independently?
Yes—the instrument provides a two-point calibration function (0 °C ice bath and 100 °C boiling water reference) accessible via service menu, supporting metrological traceability to NIST-traceable standards.
What SD card formats are supported?
FAT32 only; exFAT and NTFS are not recognized. Cards must be formatted externally before insertion.
Does the unit support RS232 or USB communication?
No—data exchange is limited to SD card logging. No serial or USB device interface is provided.
How is overtemperature protection implemented?
Dual-layer safeguard: hardware-based thermal cutoff at 550 °C (non-resettable fuse) and software-enforced limit at 500 °C with audible alert and display lockout.
