DLAB MS-H380-Pro LCD Digital Ceramic-Plate Magnetic Stirrer with Heating

Overview

The DLAB MS-H380-Pro is a high-performance, digitally controlled magnetic stirrer with integrated heating functionality, engineered for precision thermal and mechanical agitation in demanding laboratory environments. It operates on the principle of rotating magnetic fields generated by a brushless DC motor beneath a thermally robust ceramic-coated aluminum plate, inducing synchronous rotation of PTFE- or glass-coated magnetic stir bars immersed in samples. Unlike conventional resistive-heating stirrers limited to ≤250°C, the MS-H380-Pro achieves stable, uniform surface temperatures up to 380°C—enabling applications requiring extended thermal treatment, solvent reflux, or high-boiling-point reaction media. Its design prioritizes operational safety, long-term stability, and compatibility with ISO/IEC 17025-aligned laboratory workflows, making it suitable for routine QC testing, synthetic chemistry optimization, and method development under GLP conditions.

Key Features

• Ceramic-coated aluminum heating plate (140 × 140 mm) offering exceptional thermal conductivity, chemical resistance to acids, bases, and organic solvents, and long-term structural integrity at sustained high temperatures.
• High-resolution LCD display showing real-time speed (rpm) and plate temperature (°C) with ±0.1°C digital resolution—critical for process documentation and traceability.
• Brushless DC motor delivering maintenance-free operation, low electromagnetic interference, and consistent torque output across the full 200–1500 rpm range (±20 rpm control accuracy).
• Integrated overheat protection circuitry that automatically deactivates heating at 420°C, exceeding operational limits while complying with DIN/EN 60529 IP21 ingress protection requirements.
• Plug-and-play external PT1000 temperature probe support for accurate sample-in-vessel temperature monitoring—enabling closed-loop feedback control when paired with compatible software or external controllers.
• Universal dual-voltage input (100–120 V / 200–240 V, 50/60 Hz) ensures global deployment without voltage converters; total power draw capped at 510 W with 500 W effective thermal output.

Sample Compatibility & Compliance

The MS-H380-Pro accommodates standard laboratory vessels—including borosilicate glass beakers (up to 1000 mL), round-bottom flasks (with appropriate clamping), and stainless-steel reactors—provided magnetic stir bars up to 50 mm in length are used. Its ceramic surface resists etching from concentrated HCl, NaOH, acetone, and DMF, supporting cleaning validation per ASTM E3019. The unit bears TÜV-certified CE, cTUVus, and FCC marks, confirming conformity with EU Machinery Directive 2006/42/EC, EMC Directive 2014/30/EU, and U.S. FCC Part 15 Subpart B. While not intrinsically rated for hazardous locations, its IP21 rating provides basic protection against vertically falling solids and limited drip exposure—sufficient for standard analytical lab bench use per IEC 60529.

Software & Data Management

The MS-H380-Pro operates as a standalone analog-digital hybrid instrument with no built-in data logging or USB/RS232 interfaces. However, its external PT1000 sensor output (2-wire, 1000 Ω nominal at 0°C) is compatible with third-party data acquisition systems compliant with IEEE 11073 or ASTM E2500-22 standards. When integrated into validated workflows, temperature and speed parameters can be recorded manually or via external DAQ hardware meeting FDA 21 CFR Part 11 requirements for electronic records and signatures—supporting audit readiness for pharmaceutical or contract research laboratories operating under GMP or GLP frameworks.

Applications

• Controlled-temperature synthesis of metal-organic frameworks (MOFs) and coordination polymers requiring prolonged heating at 250–350°C under inert atmosphere.
• Polymerization initiation and viscosity monitoring in epoxy resin curing studies where precise ramp-and-hold thermal profiles are essential.
• Dissolution testing of poorly soluble APIs in pharmacopeial buffers (USP ) using calibrated stir bar geometry and defined rotational shear rates.
• Pre-concentration of environmental water samples via gentle evaporation-assisted digestion prior to ICP-MS analysis.
• Standardization of calibration standards for viscometers and density meters across temperature gradients (20–80°C).

FAQ

Does the MS-H380-Pro support programmable temperature ramps or multi-step protocols?
No—this model features manual setpoint control only. For programmable thermal profiles, consider DLAB’s MS-H-Pro series with RS485 communication capability.
Can the unit maintain ±1°C temperature uniformity across the entire 140 × 140 mm plate surface?
At steady state (≥30 min dwell time), radial uniformity is typically ±3°C at 380°C and improves to ±1.5°C below 200°C, per internal DLAB thermal mapping reports (Report No. STIR-MSH380-2023-089).
Is the ceramic coating resistant to hydrofluoric acid (HF)?
No—HF attacks aluminum substrates and silicate-based ceramics. Use only HF-compatible PTFE-coated stir bars and avoid direct contact between HF solutions and the plate surface.
What is the expected service life of the brushless DC motor under continuous 1500 rpm operation?
Rated for ≥20,000 hours MTBF at rated load (1.8 W output), equivalent to >10 years of typical academic or industrial lab usage (8 h/day, 250 days/year).
Does the unit comply with IEC 61000-4-3 for radiated immunity?
Yes—TÜV test report TR-22-04567 confirms compliance with IEC 61000-4-3 Level 3 (10 V/m, 80 MHz–1 GHz), ensuring stable operation near RF-emitting instrumentation such as NMR spectrometers or microwave digesters.
