Titan MPS-9 Multi-Point Magnetic Stirrer

Overview

The Titan MPS-9 Multi-Point Magnetic Stirrer is an engineered solution for parallel sample processing in analytical, quality control, and preparative laboratory workflows. Designed around a robust permanent magnet drive architecture with nine independent stirring positions, it enables simultaneous, synchronized, or individually adjustable agitation of up to nine vessels—each accommodating up to 2 L volume—without mechanical coupling or shaft penetration. Unlike overhead stirrers or single-position hotplates, the MPS-9 operates on contactless magnetic coupling: rotating magnetic fields generated beneath the ceramic-coated aluminum plate induce torque on PTFE-coated magnetic stir bars placed inside vessels. This principle ensures low maintenance, minimal contamination risk, and high reproducibility across repeated runs—critical for method standardization under GLP or ISO/IEC 17025 environments.

Key Features

• Nine independent stirring stations with individual speed control via digital rotary encoder and LED display per channel
• Ceramic-coated aluminum heating plate (non-heating variant; temperature remains ambient-only per specification)
• Speed range: 100–2000 rpm with ±2% speed stability at setpoint (measured at 1 L aqueous load, 25°C ambient)
• Integrated microprocessor-based controller with memory function for last-used settings
• Low-noise brushless DC motor design optimized for continuous operation (>10,000 hr MTBF)
• Overheat protection circuitry and automatic shutdown upon abnormal current draw or stall detection
• Compact footprint (320 × 240 × 120 mm) suitable for fume hoods, laminar flow cabinets, and benchtop QC labs

Sample Compatibility & Compliance

The MPS-9 accommodates standard laboratory glassware including beakers (50–2000 mL), Erlenmeyer flasks, and cylindrical reaction vessels with flat bottoms. Stir bar compatibility covers diameters from 8 mm to 30 mm and lengths up to 60 mm. Vessel base thickness must not exceed 12 mm for reliable coupling. As a non-regulated ambient-only device (no integrated heating element), it complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and meets RoHS Directive 2011/65/EU for hazardous substance restrictions. While not classified as a medical device or GMP-critical instrument, its consistent speed delivery supports method validation protocols aligned with ASTM D445 (kinematic viscosity) and USP (dissolution apparatus qualification) when used as part of auxiliary mixing steps.

Software & Data Management

The MPS-9 operates as a standalone analog-digital hybrid instrument without embedded connectivity (e.g., no USB, Bluetooth, or Ethernet). All operational parameters—including real-time rpm per station—are displayed locally on dual-digit LED indicators. No software drivers, firmware updates, or data logging are provided. For laboratories requiring audit trails or electronic records, external validation-compatible data loggers (e.g., compliant with FDA 21 CFR Part 11 Annex 11) may be interfaced via analog 0–5 V output (optional accessory port; not standard). Configuration changes do not require calibration certificates; however, periodic verification using a certified tachometer is recommended per internal SOPs.

Applications

• Parallel dissolution testing of solid dosage forms during pharmaceutical formulation development
• Synchronized pH adjustment and reagent mixing in multi-vial environmental water analysis (e.g., EPA Method 300.0)
• Consistent suspension preparation for particle size distribution studies (ISO 13320)
• High-throughput buffer equilibration in protein purification workflows
• Controlled agitation during titration pre-mixing or standard solution preparation in ISO/IEC 17025-accredited labs
• Uniform dispersion of nanomaterials in solvent matrices prior to TEM or DLS characterization

FAQ

Does the MPS-9 include heating capability?
No. The MPS-9 is a dedicated magnetic stirrer with ambient-only operation. It does not incorporate a heating element or temperature control circuitry.
Can speed be adjusted independently for each of the nine positions?
Yes. Each station features its own rotary encoder and digital display, allowing discrete speed selection within the 100–2000 rpm range.
Is the unit compatible with corrosive solvents such as concentrated acids or organic halides?
The ceramic-coated top plate and sealed motor housing provide resistance to mild chemical splashes, but direct exposure to aggressive solvents requires use of secondary containment and appropriate stir bar coatings (e.g., glass-encapsulated or PTFE/glass composite).
