Overview
The Titan MS-0212 Economic Magnetic Stirrer is a compact, benchtop laboratory device engineered for reliable and consistent mixing of low-viscosity aqueous and organic solutions under ambient temperature conditions. It operates on the principle of magnetic coupling: a rotating permanent magnet or electromagnetic drive beneath the work surface induces synchronous rotation of a PTFE- or glass-coated magnetic stir bar immersed in the sample vessel. This non-contact method eliminates mechanical shaft seals and contamination risks associated with overhead stirrers, making it ideal for sterile, sealed, or small-volume applications in chemistry, biology, and quality control laboratories. Designed for daily routine use—not high-precision rheological characterization—the MS-0212 delivers stable rotational performance across its full speed range without active thermal regulation, aligning with applications where temperature maintenance is not required.
Key Features
- Robust DC motor-driven platform with smooth, brushless operation ensuring long-term reliability and minimal maintenance.
- Digital speed control interface with LED display enabling precise setting and real-time monitoring of rotational speed (50–2500 rpm) in 10-rpm increments.
- Compact footprint (approx. 140 × 120 × 80 mm) optimized for space-constrained fume hoods and shared lab benches.
- Chemically resistant ceramic-coated top plate offering thermal stability up to 120 °C surface temperature and resistance to common solvents and mild acids.
- Integrated safety circuitry including over-current protection and automatic shutdown upon prolonged overload or stall detection.
- Stir bar retention groove and anti-slip rubber feet to minimize lateral displacement during extended operation.
Sample Compatibility & Compliance
The MS-0212 supports standard borosilicate glass beakers, flasks, and vials up to 2 L volume when paired with appropriately sized magnetic stir bars (e.g., 30–50 mm cross-shaped or oval bars). It is compatible with water, buffer solutions, ethanol, acetone, and dilute aqueous reagents—but not recommended for highly viscous media (>500 mPa·s), abrasive suspensions, or corrosive halogenated solvents without additional containment precautions. While not certified to ISO/IEC 17025 or GLP-specific validation protocols out-of-the-box, the unit complies with general electrical safety requirements per GB 4793.1–2007 (equivalent to IEC 61010-1) for laboratory equipment. Its design facilitates documentation of operational parameters (speed, duration) required for basic SOP adherence in non-regulated environments.
Software & Data Management
The MS-0212 operates as a standalone analog-digital hybrid instrument with no embedded firmware, network connectivity, or software interface. All settings are configured manually via front-panel controls; no data logging, remote access, or audit trail functionality is provided. This architecture intentionally prioritizes simplicity, electromagnetic compatibility (EMC), and operational transparency—eliminating cybersecurity concerns and reducing failure points common in microprocessor-dependent stirrers. For labs requiring traceable operation records, external timers or lab notebook entries synchronized with speed settings remain the recommended practice per internal QA procedures.
Applications
- Routine dissolution testing of solid dosage forms in pharmaceutical development labs.
- Buffer preparation and reagent homogenization in molecular biology workflows (e.g., lysis buffer mixing prior to centrifugation).
- pH adjustment and titrant dispersion during electrochemical sensor calibration.
- Catalyst suspension in small-scale synthetic reaction screening (≤200 mL scale).
- Standard solution preparation for UV-Vis spectroscopy and HPLC mobile phase blending.
- Educational demonstrations of fluid dynamics and mass transfer principles in undergraduate chemistry laboratories.
FAQ
Does the MS-0212 include heating capability?
No. This model provides magnetic stirring only at ambient temperature. It does not incorporate a heating plate or temperature feedback system.
What stir bar size is recommended for optimal performance at 2 L volume?
A 40–50 mm cross-type PTFE-coated stir bar is recommended for vessels ≥1 L. Smaller bars (<25 mm) may exhibit instability or vortex collapse above 1500 rpm.
Is the unit suitable for use inside an anaerobic chamber?
Yes—provided the chamber’s viewport allows unobstructed placement and the internal atmosphere is non-corrosive to the ceramic plate surface. No external power modifications are needed.
Can the MS-0212 be integrated into automated liquid handling systems?
No. It lacks digital I/O ports, RS-232/USB interfaces, or programmable logic controller (PLC) compatibility. Integration requires external relay-based switching only.
What is the expected service life under continuous 8-hour daily operation?
Based on accelerated lifecycle testing per manufacturer specifications, the motor and electronics maintain functional integrity for ≥15,000 hours when operated within rated speed and load conditions.
