2mag MIX 15 eco Multi-Position Magnetic Stirrer

Overview

The 2mag MIX 15 eco is a high-reliability, multi-position magnetic stirrer engineered for parallel sample preparation in quality control laboratories, pharmaceutical development, and academic research environments. Utilizing 2mag’s proprietary magnetic induction drive technology—free of mechanical gears, brushes, or rotating shafts—the device delivers maintenance-free, wear-free operation across all 15 independent stirring positions. Each position supports vessels up to 1,500 mL (e.g., standard 250 mL tall-form beakers arranged in a 3 × 5 grid), with precise speed synchronization ensured by a single central controller. Unlike conventional stirrers relying on permanent magnet rotation, the MIX 15 eco employs a stationary electromagnetic coil array beneath the stainless steel top plate, generating controlled rotating magnetic fields that act directly on PTFE- or glass-coated stir bars. This design eliminates torque loss at low speeds, prevents stalling under viscous load, and guarantees stable rotational behavior from 120 rpm upward—critical for reproducible dissolution testing, buffer equilibration, or reagent homogenization workflows.

Key Features

• 15 synchronized stirring positions with uniform 65 mm center-to-center spacing—optimized for compatibility with standard laboratory glassware including 50–250 mL tall-form beakers and cylindrical vials.
• Digital LED display with intuitive rotary encoder interface for real-time speed setting and monitoring; no external software required for basic operation.
• SoftStart function ensures gentle acceleration of stir bars during initiation—reducing splash risk, preventing bar ejection, and improving positioning reliability in narrow-necked containers.
• Auto-memory retention stores the last configured speed setting upon power-down, enabling rapid restart without manual reconfiguration.
• Sealed electromagnetic drive system rated IP64—dust-tight and protected against water splashing from any direction—ensuring long-term operational integrity in humid or wet benchtop conditions.
• Robust 304 stainless steel housing with smooth, non-porous surface facilitates rapid wipe-down cleaning and resists corrosion from common solvents, acids, and buffers.
• Low thermal footprint (max. 10 W per position, 150 W total) minimizes ambient heating during extended runs—supporting temperature-sensitive protocols where external heating is not applied.

Sample Compatibility & Compliance

The MIX 15 eco accommodates a broad range of vessel geometries and materials—including borosilicate glass, polypropylene, and PET—without requiring platform adapters. Its optimized magnetic field geometry ensures effective coupling with stir bars ranging from 10 × 3 mm (micro-scale) to 40 × 8 mm (ASTEROID 40 series). The device complies fully with IEC 61010-1:2010 for electrical safety in laboratory equipment and carries CE marking per EU Directive 2014/30/EU (EMC) and 2011/65/EU (RoHS). While it does not incorporate integrated temperature control, its stable mechanical design and thermal management support use within GLP-compliant workflows when paired with validated external heating plates or environmental chambers. All electrical components meet reinforced insulation requirements for Class I equipment operating in non-hazardous locations.

Software & Data Management

The MIX 15 eco operates as a standalone instrument with no embedded firmware update capability or PC connectivity. However, its deterministic speed control architecture—based on closed-loop frequency regulation—ensures ±2% speed accuracy across the full 120–1,200 rpm range, supporting audit-ready documentation under ISO/IEC 17025 and FDA 21 CFR Part 11–aligned SOPs when used with manual logbooks or LIMS-integrated electronic notebooks. Optional accessories—including ASTEROID-series high-efficiency stir bars and PTFE-coated retrieval rods—are traceable via 2mag’s certified calibration reports (available upon request), facilitating metrological traceability for critical mixing steps in method validation.

Applications

• Parallel dissolution testing of solid dosage forms (e.g., tablets, capsules) per USP and Ph. Eur. 2.9.3 guidelines.
• Buffer and media preparation for cell culture, ELISA, and PCR workflows requiring consistent homogeneity across multiple batches.
• Extraction and leaching studies in environmental and food safety labs (e.g., EN 13634, DIN 50021).
• Standardization of reference solutions in analytical chemistry QC labs—especially where batch-wise repeatability must be demonstrated across ≥10 samples.
• Preparative chromatography mobile phase blending prior to HPLC or UHPLC injection.

FAQ

Does the MIX 15 eco support temperature-controlled stirring?
No—this model operates at ambient temperature only. For heated stirring, integrate with a compatible external hotplate (e.g., 2mag HT series) while maintaining positional alignment.
Can the stirrer accommodate round-bottom flasks?
Yes—when used with appropriately sized stir bars (e.g., ASTEROID 25 or spherical PTFE-coated bars) and stabilized flask stands; optimal performance is achieved with flat-bottomed vessels.
Is speed calibration traceable to national standards?
While the unit itself is not supplied with factory calibration certificate, 2mag offers optional third-party calibration services accredited to ISO/IEC 17025, including speed verification across three points (200 / 600 / 1,000 rpm).
What maintenance is required over its service life?
None—thanks to the brushless, gearless magnetic induction drive. Routine cleaning of the stainless steel surface and periodic visual inspection of stir bars constitute the full maintenance protocol.
How is electrical safety ensured during continuous 24/7 operation?
The device features dual thermal cutoffs, reinforced insulation, and overload protection compliant with IEC 61010-1 Annex BB; it is rated for unattended operation within specified ambient limits (−10 °C to +50 °C, ≤80% RH).
