IKA MS 3 digital Orbital Shaker

Overview

The IKA MS 3 digital orbital shaker is a compact, benchtop laboratory instrument engineered for precise and reproducible orbital motion in life science and biotechnology workflows. It operates on the principle of controlled circular oscillation—generating uniform, low-shear mixing via a 4.5 mm orbit diameter—making it especially suitable for applications requiring gentle yet effective homogenization of small-volume samples in microtiter plates, centrifuge tubes, and reaction vials. Designed and manufactured in Staufen, Germany, the MS 3 digital integrates robust mechanical architecture with intuitive digital control, delivering consistent rotational stability across its full speed range (200–3000 rpm). Its zinc alloy housing ensures long-term structural integrity and electromagnetic compatibility in shared lab environments, while the sealed DC motor and optimized thermal management support continuous operation at rated load without performance degradation.

Key Features

• Digital speed and timer control with 7-segment LED display for real-time monitoring of rpm and remaining time
• Two operational modes: Mode A (safety-optimized, auto-detects standard IKA plate adapters) and Mode B (unrestricted compatibility with third-party or custom platforms)
• Pulse (short-run) function for rapid, transient agitation—ideal for intermittent mixing during ELISA wash steps or reagent resuspension
• Auto-detection of standard IKA adapter plates ensures speed limitation to 1300 rpm when non-certified accessories are used, enhancing user safety and sample integrity
• Compact footprint (148 × 205 × 63 mm) and lightweight design (2.9 kg) facilitate integration into biosafety cabinets, cold rooms, or multi-instrument workstations
• IP21-rated enclosure provides protection against vertically falling drips and solid objects >12.5 mm—suitable for standard laboratory ambient conditions (5–40 °C, ≤80% RH)
• Universal power input (100–240 V AC, 50/60 Hz) with internal 24 V DC conversion ensures stable operation across global voltage standards

Sample Compatibility & Compliance

The MS 3 digital supports standardized microtiter formats including 96-well and 384-well plates, as well as round-bottom and conical tubes up to 50 mL. Its 0.5 kg maximum load capacity (including clamps and adapters) maintains mechanical stability under dynamic loading. The shaker complies with DIN EN 60529 (IP21), CE marking directives, and RoHS 2011/65/EU requirements. While not a regulated medical device, its design aligns with GLP-relevant instrumentation principles—including traceable parameter setting, non-volatile timer configuration, and absence of undocumented firmware behavior—supporting audit readiness in quality-controlled labs. No integrated temperature control is provided; users must pair the unit with external environmental chambers if thermally constrained protocols apply.

Software & Data Management

The MS 3 digital is a stand-alone, microcontroller-based instrument with no embedded software stack, network interface, or data logging capability. All settings—including speed, timer duration, and mode selection—are configured directly via front-panel buttons and retained in non-volatile memory until manually revised. This architecture eliminates cybersecurity risks associated with connected devices and ensures deterministic response timing—a critical factor in time-sensitive assays such as kinetic enzyme reactions or synchronized cell culture agitation. For laboratories operating under FDA 21 CFR Part 11 or ISO/IEC 17025 frameworks, manual entry of instrument parameters into electronic lab notebooks (ELNs) or LIMS is recommended to maintain full procedural traceability.

Applications

• Cell culture maintenance: Gentle suspension of adherent cells during passaging or media exchange
• Immunoassay preparation: Uniform coating and washing steps in ELISA and lateral flow assay development
• Molecular biology: Resuspension of lyophilized primers, enzymes, and nucleic acid pellets
• Microbiology: Aeration of small-volume liquid cultures in test tubes or deep-well plates
• Protein biochemistry: Equilibration of binding reactions prior to centrifugation or filtration
• Quality control testing: Reproducible mixing of reference standards and calibration solutions in QC/QA labs

FAQ

Does the MS 3 digital support temperature-controlled operation?
No. It is an ambient-temperature-only orbital shaker. Integration with external incubators or cooling platforms is required for thermoregulated applications.
Can I use non-IKA microplate adapters with this shaker?
Yes—when operating in Mode B—but speed is capped at 3000 rpm regardless of adapter type. In Mode A, only certified IKA adapters trigger full-speed capability.
Is the timer programmable in seconds?
No. Time resolution is limited to minutes, with a minimum setting of 1 minute and a maximum of 99 minutes.
What maintenance is required for long-term reliability?
Routine cleaning of the platform surface and inspection of adapter clips for wear are recommended. No lubrication or recalibration is necessary—the DC motor and bearing system are sealed and pre-calibrated at factory.
Does the unit meet electromagnetic compatibility (EMC) standards for use near sensitive analytical instruments?
Yes. It conforms to EN 61326-1:2013 for laboratory equipment EMC and exhibits minimal radiated emissions, making it suitable for proximity to HPLC systems, spectrophotometers, and microscopes.
