Overview
The 2mag MIX 1 Magnetic Stirrer is a precision-engineered, single-position laboratory stirrer designed for reliable, low-maintenance mixing of aqueous, organic, and viscous media in standard glassware. Built on the principle of magnetic coupling—where a rotating permanent magnet beneath the work surface induces synchronous rotation of a PTFE- or glass-coated stir bar immersed in the sample—the MIX 1 delivers consistent torque transfer without mechanical shaft penetration. Its robust stainless-steel housing (IP64-rated) ensures resistance to chemical splashes, moisture ingress, and routine lab cleaning protocols. Engineered for daily use in QC laboratories, academic teaching labs, and R&D environments, the device operates silently and efficiently within ambient temperature conditions, eliminating the need for external cooling or heating integration.
Key Features
- Single-station configuration optimized for vessels ranging from 1 mL to 10 L—including beakers, flasks, and graduated cylinders up to Ø150 mm base diameter
- Wide speed range of 100–2000 rpm with fine incremental control via 4-step rotary power selector (25%, 50%, 75%, 100%), enabling reproducible ramping for sensitive suspensions or low-viscosity solvents
- Soft-start function prevents abrupt acceleration, minimizing vortex instability and stir bar ejection during startup—critical for homogeneous dispersion of precipitates or cell cultures
- IP64-rated stainless-steel enclosure provides dust-tight protection and resistance to water spray from any direction, supporting compliance with ISO 14644-1 Class 8 cleanroom-adjacent workflows
- No internal fan or moving parts beyond the drive magnet assembly, resulting in ultra-low maintenance requirements and extended service life (>10 years under typical usage)
- Compact footprint (approx. 130 × 130 × 95 mm) and lightweight design (~4 kg) facilitate easy repositioning across benchtops, fume hoods, or gloveboxes
Sample Compatibility & Compliance
The MIX 1 accommodates all standard magnetic stir bars (e.g., 20–60 mm length, cylindrical or oval geometry) and supports common laboratory vessel materials: borosilicate glass (DIN EN ISO 3585), polypropylene, and PTFE-lined containers. It is compatible with non-corrosive aqueous buffers, ethanol/water mixtures, and diluted acids/bases (pH 2–12). While not rated for explosive atmospheres (ATEX), its spark-free operation makes it suitable for use with flammable solvents when deployed outside classified zones per IEC 60079-0 guidelines. The unit conforms to electromagnetic compatibility standards EN 61326-1 (laboratory equipment) and safety standard EN 61010-1:2010, including protection against electric shock and mechanical hazards.
Software & Data Management
As a standalone analog-controlled instrument, the MIX 1 does not incorporate digital interfaces, firmware, or data logging capabilities. All operational parameters are set manually via the front-panel rotary dial; no software installation, calibration certificates, or electronic audit trails are provided. This architecture aligns with GLP environments where simplicity, traceability through physical logbooks, and absence of electronic validation overhead are prioritized. For users requiring electronic recordkeeping, the MIX 1 may be integrated into broader lab automation systems via external timers or programmable power relays—though such configurations fall outside the manufacturer’s validated scope per FDA 21 CFR Part 11.
Applications
- Preparation of standard solutions and calibration blanks in analytical chemistry workflows (e.g., ICP-OES, HPLC mobile phase blending)
- Homogenization of microbial growth media prior to autoclaving or filtration sterilization
- Facilitation of dissolution testing in pharmaceutical QA/QC per USP and Ph. Eur. 2.9.3
- Stirring of coating suspensions (e.g., TiO₂ in ethanol) for thin-film deposition processes
- Support of enzymatic reaction kinetics studies where gentle, continuous agitation avoids shear-induced denaturation
- Routine buffer equilibration in molecular biology labs prior to electrophoresis or chromatography runs
FAQ
Does the MIX 1 include temperature control or heating functionality?
No. The MIX 1 is a non-heating magnetic stirrer. It operates at ambient temperature only. For combined stirring and heating, consider the 2mag THERMO series or third-party hotplate-stirrer integrations.
What stir bar size is recommended for maximum 10 L capacity?
A 60 mm oval or 50 mm cylindrical stir bar with ≥5 mm diameter and PTFE/glass coating is optimal for volumes >5 L in tall-form vessels. Smaller bars (<30 mm) are suitable for ≤1 L applications.
Is the MIX 1 compliant with ISO/IEC 17025 calibration requirements?
The device has no user-accessible calibration parameters. Speed accuracy is factory-verified to ±5% of setpoint across the full range. External verification using a tachometer is recommended annually per ISO/IEC 17025 Clause 6.5.2.
Can the MIX 1 be used inside a CO₂ incubator or cold room?
Yes—provided ambient humidity remains ≤80% and temperature stays within –10 °C to +50 °C. Condensation must be prevented; avoid rapid thermal cycling or placement directly under cooling vents.
What maintenance is required for long-term reliability?
Wipe the stainless-steel surface with isopropyl alcohol after each use. Inspect stir bars for chipping or coating wear quarterly. No lubrication or internal servicing is needed; the sealed magnet drive requires zero periodic maintenance.
