Overview
The IKA Mini TONY is a compact, battery-operated portable magnetic stirrer engineered for precision mixing in field laboratories, teaching environments, quality control checkpoints, and low-footprint benchtop applications where mains power is unavailable or impractical. Unlike conventional AC-powered stirrers, the Mini TONY employs a brushless DC motor—eliminating carbon brush wear, reducing electromagnetic interference, and ensuring long-term rotational stability across its full speed range. Its operating principle relies on rotating magnetic coupling between the internal drive magnet and an external stirring bar immersed in the sample vessel. This contactless torque transfer enables consistent agitation of low-viscosity aqueous and organic solutions up to 250 mL without mechanical vibration transmission or heat generation from motor friction. Designed to meet DIN EN 60529 IP20 ingress protection requirements, the unit is rated for indoor laboratory use under non-hazardous ambient conditions (5–40 °C), with thermal management optimized to sustain continuous operation during extended protocols.
Key Features
- Brushless DC motor architecture for maintenance-free operation, high reproducibility, and extended service life
- Stepless speed control via rotary encoder, delivering stable rotation from 300 to 1800 rpm with ±10 rpm repeatability at setpoint
- High-coercivity neodymium magnetic drive system—prevents “jumping” of stirring bars even at maximum speed and under off-center loading
- Lightweight polypropylene (PP) work surface resistant to common solvents, acids, and bases; chemically inert and autoclavable (surface wipe-clean only)
- Dual-power flexibility: operates on four standard rechargeable AA NiMH cells (included) or external 9 V DC adapter—no battery required during continuous bench use
- Integrated LED status indicators for battery level, charging state, and active speed mode
- Low-noise operation (<45 dB(A) at 1 m), suitable for quiet environments including analytical prep labs and classroom demonstrations
Sample Compatibility & Compliance
The Mini TONY accommodates standard cylindrical and conical glassware (e.g., beakers, Erlenmeyer flasks) with diameters from 30 mm to 80 mm. It supports PTFE- or glass-coated stirring bars up to 40 mm in length and 8 mm in diameter. While not designed for viscous media (>500 mPa·s) or high-density suspensions, it delivers reliable homogenization for buffer preparation, reagent dilution, titration standardization, and cell culture medium equilibration. The device complies with IEC 61010-1:2010 for electrical safety in laboratory equipment and conforms to RoHS 2011/65/EU and REACH (EC) No. 1907/2006 directives. Its IP20 rating indicates protection against solid objects ≥12.5 mm—appropriate for controlled indoor lab settings but not splash-prone or wet environments.
Software & Data Management
As a standalone analog-controlled instrument, the Mini TONY does not feature embedded firmware, USB connectivity, or digital data logging. All operational parameters are adjusted manually and retained only as physical setpoints. This design prioritizes reliability, electromagnetic compatibility (EMC), and regulatory simplicity—making it suitable for ISO/IEC 17025-accredited testing labs where traceable calibration of electronic interfaces is not required. For users requiring audit trails or integration into LIMS workflows, external time-stamped video recording or manual logbook entries (per GLP Annex 11 guidance) are recommended practices.
Applications
- Routine pH adjustment and buffer blending in environmental water analysis field kits
- Small-scale dissolution testing during pharmaceutical formulation screening
- Homogenization of calibration standards for spectrophotometry and ion chromatography
- Student-led experiments in university chemistry and biology teaching labs
- On-site QC checks in food processing facilities (e.g., acid titration of vinegar samples)
- Preparation of nanoparticle dispersions prior to DLS or TEM analysis
FAQ
Is the Mini TONY compatible with temperature-controlled blocks or heating plates?
No. The Mini TONY is a non-heating stirrer. It lacks integrated heating elements or thermal feedback circuitry. For combined stirring and heating, consider the IKA RCT basic or C-MAG HS models.
Can it be used with corrosive solvents such as concentrated HCl or acetone?
The PP work surface offers broad chemical resistance, but direct prolonged exposure to strong oxidizers or halogenated solvents may degrade surface integrity over time. Always consult the IKA Chemical Resistance Guide (Doc. No. 50000098) before use.
Does the device support FDA 21 CFR Part 11 compliance?
Not applicable. As a manually operated, non-data-generating instrument, it falls outside the scope of electronic record and signature regulation requirements.
What is the recommended calibration interval?
IKA recommends annual verification of speed accuracy using a certified optical tachometer per ISO 8466-1:2021. No factory recalibration is required unless physical damage occurs.
Are replacement stirring bars supplied by IKA?
Yes. Compatible stir bars (e.g., IKA Cat. No. 0030000211, PTFE-coated, 30 × 7 mm) are available through authorized distributors and carry full CE and RoHS declarations.
