DLAB MS6-Pro LCD Digital Magnetic Stirrer with 140×140 mm Ceramic-Coated Aluminum Plate

Overview

The DLAB MS6-Pro is a precision-engineered digital magnetic stirrer designed for routine and demanding laboratory applications requiring reliable, repeatable mixing without thermal input. Unlike heated stirrers, the MS6-Pro operates as a dedicated non-heating mixing platform—ideal for temperature-sensitive samples, volatile solvents, or protocols where exothermic reactions must be monitored externally. Its core operation relies on a rotating magnetic field generated by a brushless DC motor beneath a rigid ceramic-coated aluminum plate, which couples with magnetic stir bars to induce controlled fluid motion via magnetohydrodynamic torque transfer. The device is optimized for high reproducibility in low- to medium-viscosity aqueous and organic media, supporting consistent homogenization, dissolution, and reagent dispersion across analytical, synthetic, and quality control workflows.

Key Features

• High-resolution LCD display showing real-time rotational speed (200–1500 rpm) with ±20 rpm control accuracy—enabling precise method replication across users and shifts.
• Brushless DC motor architecture ensures maintenance-free operation, extended service life (>10,000 hours MTBF), low electromagnetic interference, and silent performance under load.
• 140 × 140 mm square working surface fabricated from aerospace-grade aluminum substrate, uniformly coated with chemically inert, abrasion-resistant ceramic—resistant to strong acids (e.g., HCl, HNO₃), bases (e.g., NaOH), and organic solvents (e.g., acetone, ethanol, DMSO).
• Digital speed regulation via push-button interface with memory function—recalls last-used setting upon power-up, reducing setup time in multi-step protocols.
• Robust mechanical design certified to IP21 ingress protection level—providing basic resistance against vertically falling drips and solid objects >12.5 mm, suitable for standard laboratory bench environments.
• Universal AC input (100–240 V, 50–60 Hz) enables seamless deployment across global laboratories without voltage converters or regional variants.

Sample Compatibility & Compliance

The MS6-Pro accommodates standard laboratory glassware including beakers (up to 1000 mL), Erlenmeyer flasks (up to 2000 mL), and cylindrical vessels—supporting effective mixing of up to 5 L water-equivalent volume using appropriately sized stir bars (max. 40 mm length). It complies with international safety standards including CE (EU Machinery Directive 2006/42/EC), cTUVus (UL 61010-1, CAN/CSA C22.2 No. 61010-1), and FCC Part 15 Class B for electromagnetic compatibility. Conformance with DIN/EN 60529 (IP21) validates its suitability for general-purpose lab use under controlled ambient conditions (5–40 °C, ≤80% RH, non-condensing). While not designed for GMP or GLP-regulated environments requiring audit trails, its deterministic digital control and stable mechanical output support SOP-driven operations in QC labs adhering to ISO/IEC 17025 documentation practices.

Software & Data Management

The MS6-Pro operates as a standalone hardware instrument with no embedded firmware-based data logging, remote connectivity, or PC interface. All operational parameters—including set speed and real-time feedback—are displayed locally on the monochrome LCD panel. This architecture prioritizes reliability, electromagnetic noise immunity, and regulatory simplicity—eliminating software validation requirements under FDA 21 CFR Part 11 or EU Annex 11. For laboratories requiring traceability, manual recording of speed settings and duration per protocol remains the recommended practice. Optional integration with external environmental monitoring systems (e.g., via analog voltage output modules) can be implemented at system level, though not natively supported by the unit.

Applications

• Preparation of calibration standards and reference solutions in analytical chemistry (e.g., ICP-MS, HPLC mobile phase blending).
• Homogenization of cell suspensions and buffer equilibration in molecular biology and microbiology workflows.
• Controlled dissolution testing of pharmaceutical excipients and active ingredients under isothermal conditions.
• Mixing of catalyst slurries and reagent solutions in organic synthesis where thermal degradation must be avoided.
• Supporting titration setups, pH adjustment, and redox reaction monitoring in teaching and research laboratories.
• Routine QA/QC tasks including viscosity sample conditioning (pre-rheometry), particulate suspension stability assessment, and extractive solvent equilibration.

FAQ

Does the MS6-Pro include a heating function?
No. The MS6-Pro is a non-heating magnetic stirrer. It provides only rotational mixing. For combined heating and stirring, consider DLAB’s MS-H series or other thermostatic models.
What is the maximum recommended stir bar length?
40 mm. Longer stir bars may cause instability or inefficient coupling at higher speeds (>1200 rpm) due to increased moment arm and drag-induced wobble.
Is the ceramic coating resistant to hydrofluoric acid (HF)?
No. While highly resistant to most common lab chemicals, the ceramic layer is not HF-compatible. Avoid contact with HF, molten alkalis, or prolonged exposure to concentrated phosphoric acid.
Can the MS6-Pro be used inside a fume hood?
Yes—provided ambient temperature remains within 5–40 °C and relative humidity does not exceed 80% RH. Ensure adequate ventilation around the rear ventilation grilles to prevent thermal buildup.
Does it support RS-232 or USB communication?
No. The MS6-Pro has no digital communication ports or programmable interfaces. It is a manually operated, self-contained instrument.
