2MAG MIX 1 Magnetic Stirrer

Overview

The 2MAG MIX 1 Magnetic Stirrer is a precision-engineered, single-position laboratory stirrer designed for reliable, reproducible mixing across diverse chemical, pharmaceutical, and life science applications. Based on permanent magnet coupling and rotating magnetic field generation, the device induces rotational motion in PTFE- or glass-coated magnetic stir bars placed within vessels—enabling contactless torque transfer without mechanical seals or moving external parts. Its robust stainless-steel housing (IP64-rated) ensures durability in routine lab environments, while the soft-start function minimizes splashing and protects sensitive samples during acceleration. Engineered in Germany to stringent DIN and IEC 61000-6-3 electromagnetic compatibility standards, the MIX 1 delivers stable speed control over its full 100–2000 rpm range, supporting viscosity ranges from low-viscosity aqueous solutions to moderately viscous organic solvents and polymer solutions.

Key Features

• Single-position design optimized for vessels up to 10 L capacity, with precise speed regulation across 100–2000 rpm
• Four-step power setting (25%, 50%, 75%, 100%) enables fine-tuned torque delivery for varying load conditions
• Soft-start functionality ensures gradual ramp-up of rotation speed, reducing vortex formation and sample loss
• Stainless-steel housing (AISI 304) with IP64 ingress protection resists corrosion and facilitates rapid cleaning between experiments
• Compact footprint (~200 × 150 × 90 mm) and lightweight construction (~4 kg) support benchtop flexibility and ergonomic placement
• Compliant with CE marking requirements, RoHS Directive 2011/65/EU, and EN 61326-1 for laboratory electrical equipment

Sample Compatibility & Compliance

The MIX 1 accommodates standard laboratory glassware including beakers (up to 10 L), Erlenmeyer flasks, and cylindrical reaction vessels. It is compatible with all commercially available magnetic stir bars—particularly those with high magnetic moment (e.g., 30–50 mm length, dual-core or elliptical geometry) for efficient coupling at elevated viscosities. The unit operates safely under ambient conditions ranging from −10 °C to +50 °C at relative humidity ≤80%. As an EU-imported instrument, it conforms to ISO/IEC 17025-relevant traceability requirements for calibration documentation upon request and supports GLP-compliant workflows through consistent performance logging when integrated with external data acquisition systems.

Software & Data Management

While the MIX 1 operates as a standalone analog-controlled instrument, its architecture is fully compatible with 2MAG’s digital ecosystem. When paired with optional Mixcontrol20 or Mixcontrol40 control units (sold separately), users gain digital speed and power parameter display, programmable start/stop sequences, and multi-unit synchronization capability. The Mixcontrol40 interface supports audit-trail-ready operation per FDA 21 CFR Part 11 guidelines when used with validated software platforms. All firmware updates and technical documentation are accessible via 2MAG’s secure customer portal, which maintains revision-controlled release notes and compliance certificates aligned with ISO 9001:2015 quality management system requirements.

Applications

• Homogenization of reagent solutions prior to titration, spectrophotometry, or HPLC sample preparation
• Controlled mixing during dissolution testing (aligned with USP and Ph. Eur. 2.9.3)
• Buffer equilibration and pH adjustment in molecular biology workflows
• Catalyst suspension in small-scale synthetic chemistry reactions
• Cell culture media preparation under aseptic conditions using sterilizable stir bars
• Quality control testing of suspensions and emulsions in pharmaceutical manufacturing (GMP Annex 1-aligned environments)

FAQ

Is the MIX 1 suitable for viscous samples such as glycerol or polymer solutions?
Yes—when used with appropriately sized high-moment stir bars (e.g., 40 mm elliptical), the MIX 1 maintains stable rotation up to ~500 mPa·s at mid-range speeds (800–1200 rpm). For higher viscosities (>1000 mPa·s), pairing with a Mixcontrol40 controller and HT-rated stir bar is recommended.
Can the MIX 1 be used inside incubators or cold rooms?
It is rated for operation between −10 °C and +50 °C; however, condensation risk in high-humidity cold rooms may affect long-term reliability. For continuous use below 15 °C, consult 2MAG’s environmental adaptation guide for optional protective housing.
Does the MIX 1 include a built-in temperature sensor or heating function?
No—the MIX 1 is a non-heating stirrer. For combined stirring and heating, refer to the hotMIX 1 series, which integrates a PT1000 Class B sensor and independent thermal control up to 200 °C.
What maintenance is required for long-term operation?
None beyond periodic surface cleaning with ethanol or isopropanol. The brushless drive motor and sealed magnetic coupling eliminate wear components—consistent with 2MAG’s zero-maintenance design philosophy.
Is calibration documentation provided with the instrument?
Factory calibration data (speed accuracy ±2% full scale, repeatability <±1 rpm) is included in the Certificate of Conformance. Full ISO/IEC 17025 calibration services are available through authorized 2MAG service centers upon request.
