Overview
The Titan MPS-6 Multi-Point Magnetic Stirrer is an engineered benchtop solution for simultaneous, independent agitation of up to six samples under identical or differentiated speed conditions. Designed for high-throughput laboratories in pharmaceutical development, quality control, chemical synthesis, and environmental testing, the MPS-6 operates on the principle of rotating magnetic fields generated by embedded rare-earth magnets beneath each station. Each of the six stirring positions features a dedicated DC motor and precision Hall-effect feedback loop, enabling stable rotational output across the full 100–2000 rpm range without torque drop at low speeds or thermal drift at sustained high-speed operation. Unlike single-station stirrers, the MPS-6 eliminates inter-sample variability caused by sequential processing—ensuring experimental reproducibility critical for method validation, dissolution testing, and kinetic studies. Its compact footprint (280 × 320 × 95 mm) and modular aluminum alloy housing support integration into laminar flow hoods, fume hoods, and automated lab workflows.
Key Features
- Six independently controllable stirring stations with digital speed setting and real-time RPM display per channel
- Brushless DC motors with closed-loop speed regulation—±2% speed accuracy across entire 100–2000 rpm range
- High-torque ceramic-coated stir bars compatible with glass, PTFE, and borosilicate vessels (up to 2 L per station)
- Non-heating design optimized for ambient-temperature applications requiring thermal stability (e.g., enzymatic assays, pH titrations, buffer equilibration)
- IP20-rated enclosure with reinforced polycarbonate top plate and anti-slip silicone feet for vibration-damped operation
- Front-panel keypad with lockable interface and memory function to recall last-used settings after power cycle
- CE-compliant electromagnetic compatibility (EN 61326-1) and electrical safety (EN 61010-1) certification
Sample Compatibility & Compliance
The MPS-6 accommodates standard laboratory glassware including beakers (50–1000 mL), Erlenmeyer flasks (125–2000 mL), and cylindrical reaction vessels with flat-bottom geometry. Stir bar selection is application-dependent: 25 mm × 8 mm PTFE-coated bars are recommended for low-viscosity aqueous solutions; 40 mm × 10 mm elliptical bars provide enhanced vortexing for heterogeneous suspensions. The device meets ISO/IEC 17025 requirements for equipment verification when used within defined operational limits. While not equipped with integrated heating, its ambient-only operation aligns with ASTM E2915-22 guidelines for non-thermal mixing validation and supports GLP-compliant documentation protocols where temperature-sensitive reactions must remain unheated during agitation.
Software & Data Management
The MPS-6 operates as a standalone instrument without proprietary software dependency. All operational parameters—including setpoint speed, runtime, and station activation status—are retained locally in non-volatile memory. For laboratories implementing electronic lab notebooks (ELNs) or LIMS integration, optional RS-232 serial output (standard) enables ASCII-based command/response communication for external logging of start/stop events and speed confirmation per channel. Firmware supports Modbus RTU protocol (via optional adapter) for centralized monitoring in industrial-grade automation environments. Audit trails are maintained via manual logbook entries or timestamped ELN records; no FDA 21 CFR Part 11 electronic signature capability is provided, consistent with its classification as a Class I general-purpose laboratory accessory.
Applications
- Parallel dissolution testing of solid dosage forms across multiple pH media
- Simultaneous preparation of calibration standards for ICP-MS, HPLC, and UV-Vis analysis
- Homogenization of microbial culture broths prior to centrifugation or filtration
- Controlled agitation during immunoassay plate coating and washing steps
- Batch-wise mixing of reagent kits for clinical diagnostics manufacturing
- Accelerated stability studies involving multi-condition sample arrays
FAQ
Does the MPS-6 include heating functionality?
No. The MPS-6 is a non-thermal magnetic stirrer designed exclusively for ambient-temperature mixing. It does not incorporate heating plates or temperature sensors.
Can I use the MPS-6 inside a CO₂ incubator?
Not recommended. The unit is rated for operation at 15–35°C and 20–80% RH. Elevated humidity and CO₂ exposure may compromise internal electronics and motor longevity.
What is the maximum viscosity it can handle at 2000 rpm?
At full speed, optimal performance is maintained for Newtonian fluids up to 500 mPa·s (e.g., 40% glycerol/water). For higher viscosities, reduce speed to ≤800 rpm and use extended-length stir bars.
Is calibration required before first use?
No factory calibration is needed. Users should verify speed accuracy using a handheld tachometer against each station’s displayed RPM before initiating regulated experiments.
How is maintenance performed?
Routine cleaning involves wiping the surface with 70% ethanol. No lubrication or internal servicing is required during the specified 5-year operational lifespan under normal usage conditions.
