WIGGENS MIXdrive 1 XS Mini Stirrer Drive Unit

Overview

The WIGGENS MIXdrive 1 XS is a compact, high-integrity stirrer drive unit engineered for precise, low-volume mixing in demanding laboratory environments. Unlike conventional magnetic stirrers, the MIXdrive 1 XS operates on an electromagnetic induction principle—generating a rotating magnetic field without mechanical contact between drive and stir bar—ensuring zero wear, no heat transfer via coupling, and immunity to vibration-induced misalignment. Its miniature footprint (48 × 48 × 18 mm) and IP68-rated sealed housing enable direct integration into temperature-controlled chambers, glove boxes, anaerobic workstations, and even submerged applications (e.g., water baths up to +95 °C). The system supports two operational configurations: the standard MIXdrive 1 XS for vials, tubes, and small beakers (1–1000 mL), and the cuvetteMIXdrive 1 variant optimized for optical cuvettes (1–25 mL), preserving path-length integrity during kinetic assays or spectroscopic monitoring.

Key Features

• Electromagnetic drive architecture eliminates mechanical shafts, bearings, or seals—ensuring maintenance-free operation and long-term repeatability.
• IP68 ingress protection certified for continuous submersion and exposure to condensation, solvents, and aggressive cleaning agents.
• Dual thermal rating: stable operation from −10 to +50 °C under 100% relative humidity; optional HT variant (Order No. 40303) withstands +200 °C in oven environments.
• 48 V DC low-voltage power supply enhances electrical safety in wet or conductive lab settings, compliant with IEC 61010-1 safety standards for laboratory equipment.
• Stainless steel and polyurethane (PUR) housing resists corrosion from acids, bases, and organic solvents—suitable for GLP-compliant QC labs and regulated pharmaceutical workflows.
• Compact form factor enables modular mounting on robotic liquid handlers, incubators, or custom-built reaction blocks without spatial compromise.

Sample Compatibility & Compliance

The MIXdrive 1 XS accommodates standard PTFE- or glass-coated magnetic stir bars (2–10 mm length) across vessels ranging from 1.5 mL microcentrifuge tubes to 1 L jacketed reactors. The cuvetteMIXdrive 1 variant includes a precision-machined alignment sleeve ensuring centric rotation within 10 × 10 mm and 12.5 × 12.5 mm square cuvettes—critical for absorbance uniformity in UV-Vis kinetics. Device compliance includes CE marking per Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), RoHS 2011/65/EU, and conformity with ISO/IEC 17025 requirements for equipment used in accredited testing laboratories. It supports audit-ready documentation packages required for FDA 21 CFR Part 11–aligned environments when paired with validated control software.

Software & Data Management

While the MIXdrive 1 XS operates as a standalone analog device (no embedded microcontroller), its 48 V DC input allows seamless integration with programmable power supplies or PLC-based lab automation systems. Users may log operational parameters—including run duration, duty cycle, and ambient temperature—via external data acquisition modules (e.g., NI CompactDAQ or Keysight DAQ970A). For traceability in regulated settings, the device’s serial-numbered housing and order-specific calibration certificates (available upon request) fulfill instrument qualification requirements under GMP Annex 15 and USP . Firmware-upgradable controllers (sold separately) enable time-stamped start/stop logging and remote status polling via Modbus RTU over RS-485.

Applications

• Homogenization of viscous biological samples (e.g., cell lysates, hydrogels) in sealed tubes under inert atmosphere.
• In-situ mixing during real-time spectroscopy—enabling dynamic monitoring of enzyme kinetics or polymerization reactions in cuvettes.
• Temperature-stable agitation in environmental simulation chambers for accelerated stability studies (ICH Q1A).
• Low-noise stirring in electrophysiology rigs or microfluidic interface modules where mechanical vibration must be eliminated.
• High-throughput sample preparation in automated QC workflows, including dissolution testing per USP and particle dispersion for DLS sample conditioning.

FAQ

Can the MIXdrive 1 XS be used inside a CO₂ incubator?
Yes—the IP68 rating and −10 to +50 °C operating range with full humidity tolerance make it suitable for continuous use in humidified incubators without condensation-related failure.
Is the cuvetteMIXdrive 1 compatible with quartz cuvettes?
Yes—its non-magnetic stainless steel/PUR construction prevents eddy current heating, and the alignment sleeve ensures rotational symmetry without scratching optical surfaces.
Does the device require recalibration after thermal cycling?
No—electromagnetic field generation is inherently drift-free; however, periodic verification using a calibrated stir bar rotation sensor (e.g., WIGGENS ST-100) is recommended per ISO/IEC 17025 clause 6.5.2.
Can multiple MIXdrive units be synchronized?
Yes—when powered from a shared, ripple-free 48 V DC source with matched load impedance, phase coherence across units exceeds 99.2% (measured via Hall-effect probe at 1 kHz sampling).
What documentation is provided for regulatory submissions?
Factory calibration report, EU Declaration of Conformity, material compliance dossier (REACH, RoHS), and optional IQ/OQ protocols aligned with ASTM E2500-13 are available upon order confirmation.
