Overview
The IKA MS3 Basic and Digital Vortex Mixer is a compact, high-reliability orbital shaker engineered for precise, reproducible mixing of small-volume samples in laboratory environments. Based on the proven principle of eccentric orbital motion—where a motor-driven eccentric drive generates a consistent 4.5 mm orbit diameter—the MS3 delivers uniform agitation across tubes (0.2–50 mL), PCR strips, microcentrifuge tubes, and standard 96-well microplates. Its robust zinc-coated cast iron housing ensures mechanical stability and long-term resistance to chemical exposure and mechanical wear, while the sealed motor assembly supports uninterrupted 100% duty-cycle operation under routine QC, clinical, or research conditions. Designed for integration into ISO 17025-accredited labs and GLP-compliant workflows, the MS3 meets IEC 61010-1 safety requirements for electrical laboratory equipment and carries CE and RoHS certifications.
Key Features
- Two operational variants: MS3 Basic (analog speed scale, no timer) and MS3 Digital (LED digital speed display + programmable countdown timer with audible end signal)
- Dual-mode control logic: Mode A enforces automatic pad detection to limit speed to 3000 rpm only when the certified IKA standard pad is installed; non-standard pads trigger a safety-limited 1300 rpm ceiling. Mode B bypasses pad verification for full 3000 rpm capability across all compatible accessories.
- True continuous operation capability supported by thermally optimized 8 W output motor and low-noise brushless design—no thermal throttling or duty-cycle interruption required.
- Ergonomic footprint (148 × 63 × 205 mm) and integrated anti-slip rubber feet minimize benchtop displacement during high-speed vortexing.
- Universal AC input (100–240 V, 50/60 Hz) with internal 24 V DC conversion ensures stable performance across global voltage standards without external transformers.
- IP21-rated enclosure provides protection against vertically falling drips and solid objects ≥12.5 mm—suitable for general lab use but not wet or splash-prone environments.
Sample Compatibility & Compliance
The MS3 accommodates common low-volume sample containers via interchangeable IKA-certified vortex pads—including conical tube holders, PCR strip adapters, and a dedicated 96-well microplate pad. Each pad features embedded identification geometry recognized by the Mode A sensor system. The device complies with DIN EN 60529 (IP21), IEC 61010-1 (safety of laboratory equipment), and EU Directive 2014/30/EU (EMC). While not FDA 21 CFR Part 11–enabled (lacking audit trail or electronic signature functionality), its deterministic behavior, fixed firmware, and absence of user-modifiable calibration parameters render it suitable for non-regulated applications and as a supporting tool in GMP-aligned environments where manual recordkeeping is maintained.
Software & Data Management
The MS3 operates as a standalone hardware instrument with no embedded software stack, network interface, or data export capability. Speed and timer settings (on Digital model) are retained only during active power-on state and do not persist across power cycles. No drivers, firmware updates, or configuration utilities are provided or required. This architecture eliminates cybersecurity attack surfaces and ensures deterministic performance traceable to factory calibration—ideal for labs prioritizing simplicity, validation stability, and minimal IT dependency. All operational parameters are directly observable via front-panel indicators (analog scale or LED digits), supporting direct operator verification per SOP requirements.
Applications
- Routine resuspension of lyophilized reagents, cell pellets, and precipitated nucleic acids in molecular biology workflows
- Homogenization of immunoassay reagents prior to ELISA plate loading
- Pre-analytical mixing of clinical specimens (e.g., whole blood, serum, urine) in diagnostic laboratories
- Standardized agitation during enzymatic digestion, ligase reactions, or restriction digest optimization
- Quality control testing of viscosity-sensitive formulations in pharmaceutical development labs
- Teaching laboratories requiring durable, intuitive instrumentation for undergraduate practical instruction in biochemistry and microbiology
FAQ
Does the MS3 support external data logging or computer control?
No. The MS3 has no RS232, USB, analog output, or network interface. It is a manually operated analog/digital instrument without connectivity features.
Can the MS3 be used with deep-well plates or 384-well microplates?
No. The MS3 is validated only for single 96-well standard-height microplates. Deep-well or 384-well formats exceed mechanical load limits and orbit stability constraints.
Is speed calibration traceable to national standards?
IKA provides factory calibration documentation upon request. Speed accuracy is specified as ±5% of set value across the 200–3000 rpm range, verified using NIST-traceable tachometric reference instruments.
What maintenance is required?
No scheduled maintenance is required. Periodic visual inspection of pad mounting integrity and cleaning of the platform surface with 70% ethanol is recommended. The sealed motor requires no lubrication or servicing over its rated service life.
How does Mode A enforce pad detection?
Mode A uses mechanical keying: only the original IKA standard pad engages the internal cam switch. Non-OEM or modified pads fail to actuate the switch, triggering firmware-enforced speed limitation to 1300 rpm as a safety measure.
