2mag STIRRING DRYBATH 15-100 Heated Multi-Position Magnetic Stirrer

Overview

The 2mag STIRRING DRYBATH 15-100 is a precision-engineered, multi-position heated magnetic stirrer designed for parallel sample processing in analytical, pharmaceutical, and materials science laboratories. Unlike conventional hotplate stirrers, this system integrates a robust aluminum heating block with an induction-based magnetic drive architecture—eliminating mechanical wear and ensuring long-term operational stability. It operates on the principle of contactless magnetic coupling: rotating magnetic fields generated beneath the block induce synchronous rotation of PTFE- or glass-coated stir bars within vessels placed in the 15 precisely spaced wells. The system delivers uniform thermal distribution across all positions via a high-efficiency PTFE-coated aluminum block and integrated PID-controlled resistive heating, enabling reproducible temperature setpoints from +40 °C to +200 °C. Its design prioritizes thermal homogeneity, low thermal inertia, and minimal inter-vessel temperature deviation—critical for kinetic studies, dissolution testing, and accelerated stability protocols under GLP-compliant workflows.

Key Features

• 15 independent stirring positions with standardized 57.5 mm diameter × 48 mm depth wells—optimized for 100 mL Schott-type bottles and upright 150 mL beakers
• Induction-driven magnetic stirring: zero-maintenance, brushless operation with full 100–2000 rpm speed range and 100% rotational synchronicity even at low speeds (e.g., 100 rpm)
• Digital SoftStart function ensures reliable stir bar centering and smooth acceleration—reducing vortex instability and splashing during startup
• PowerDetect technology dynamically compensates for torque loss caused by viscosity increases or elevated temperature (up to 40% power adjustment), maintaining consistent agitation without manual intervention
• PTFE-coated aluminum heating block offers superior chemical resistance, rapid thermal response, and minimal surface contamination risk
• Insulated stainless steel frame minimizes ambient heat loss, improves energy efficiency, and provides passive overtemperature protection
• Integrated overtemperature cutoff and thermal runaway prevention per IEC 61000-4-2 compliance
• Dual digital display (speed, power %, temperature) with intuitive rotary encoder interface on the heatMIXcontrol unit
• Stainless steel housing (IP20-rated) protects internal electronics from corrosive vapors, condensation, and thermal stress during extended operation

Sample Compatibility & Compliance

The STIRRING DRYBATH 15-100 accommodates standard laboratory vessels including DIN 12330-compliant 100 mL narrow-neck bottles, ISO 17987-certified 150 mL tall-form beakers, and custom cylindrical containers with outer diameters ≤56 mm. Its heating geometry ensures axial temperature gradients <±1.2 °C across the vessel height at steady state (measured per ASTM E2251). The system meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not inherently 21 CFR Part 11 compliant, its heatMIXcontrol unit supports audit-trail-capable data logging when paired with validated third-party software—enabling traceability for GMP-regulated environments. All materials in contact with the heating block conform to USP Class VI biocompatibility standards.

Software & Data Management

The standalone heatMIXcontrol unit operates without PC dependency but features an RS-232 port (optional USB-to-serial adapter) for integration into LIMS or ELN platforms. It records timestamped logs of setpoint values, actual temperatures, and speed profiles—exportable as CSV for post-run analysis. Firmware supports user-defined ramp-hold programs (up to 3 segments) and password-protected parameter locking to prevent unauthorized changes. When deployed in regulated settings, the system can be validated per IQ/OQ protocols using NIST-traceable thermocouples and calibrated tachometers; documentation templates are available upon request from 2mag’s Technical Support team.

Applications

• Parallel dissolution testing of solid dosage forms (USP Apparatus II equivalent setup)
• Accelerated aging studies requiring precise thermal-agitation coupling (e.g., polymer degradation, catalyst screening)
• High-throughput buffer equilibration and reagent preparation in QC labs
• Enzyme kinetics assays where temperature-sensitive activity must be maintained across replicates
• Pre-concentration steps in environmental sample prep (e.g., evaporation-assisted extraction)
• Material synthesis involving viscous precursors—leveraging PowerDetect for stable low-RPM agitation up to 200 °C

FAQ

What vessel types are compatible with the 15-well block?
Standard 100 mL Schott bottles (DIN 12330), 150 mL tall-form beakers (ISO 17987), and any cylindrical container with OD ≤56 mm and height ≤120 mm.
Is the system suitable for use under inert atmosphere?
Yes—provided vessels are sealed with gas-tight caps; the block design allows unobstructed access to vessel necks for purge lines or septa.
Does it support external temperature probes for vessel-specific feedback control?
No—the system uses block-integrated Pt100 sensors only; vessel internal temperature must be verified independently using calibrated immersion probes.
Can multiple units be synchronized for uniform process conditions?
Not natively; each unit operates autonomously, though identical setpoints can be replicated manually or via batch configuration scripts in connected LIMS.
What maintenance is required for long-term reliability?
None beyond periodic cleaning of the PTFE-coated block surface with ethanol or isopropanol; no lubrication or calibration is needed due to solid-state induction drive and factory-trimmed PID tuning.
