IKA MS 3 control Orbital Shaker

Overview

The IKA MS 3 control is a compact, microprocessor-controlled orbital shaker engineered for precision and reliability in routine laboratory workflows. It operates on the principle of orbital motion—generating a smooth, circular oscillation with a fixed 4.5 mm diameter path—to ensure homogeneous mixing of low-volume samples in tubes (e.g., Eppendorf, PCR, microcentrifuge) and standard 96-well microplates. Designed for benchtop use in QC labs, academic research settings, and clinical diagnostics, the device delivers stable rotational performance across its full speed range (100–3000 rpm), with real-time digital feedback via integrated LCD display. Its robust die-cast aluminum and ABS housing provides mechanical stability and resistance to common lab solvents and cleaning agents, while the IP21 ingress protection rating ensures safe operation under typical ambient laboratory conditions (5–40 °C, ≤80 % RH non-condensing).

Key Features

• Microprocessor-based speed and timer control with ±1 % speed accuracy and adjustable resolution down to 1 rpm
• Dual operational modes: Mode A (safety-interlocked pulse mode with detection plate; max 3000 rpm only in touch mode with standard plate) and Mode B (unrestricted 3000 rpm with all compatible plates—refer to included accessory compatibility chart)
• Integrated pulse (touch) function enabling momentary activation without preset timing—ideal for quick resuspension prior to centrifugation or pipetting
• LCD display showing real-time speed, elapsed time, or remaining countdown; timer programmable from 1 second to 59 minutes 59 seconds (3599 s)
• USB and RS-232 interfaces support remote command execution and integration into automated lab systems (e.g., LIMS or custom scripts); compatible with IKA Labworld software for parameter logging and audit trail generation
• 100 % duty cycle rating ensures uninterrupted 24/7 operation without thermal derating or performance drift
• Optimized motor architecture (8 W output, 10 W input) delivers consistent torque across the entire speed range, minimizing sample shear during low-speed incubation or high-speed homogenization

Sample Compatibility & Compliance

The MS 3 control accommodates standard microtubes (0.2–15 mL), PCR strips, and single 96-well microplates (flat-bottom, U/V-bottom, or skirted formats) when used with IKA-certified clamping accessories. Optional adapter plates—including universal tube holders, deep-well plate supports, and PCR frame inserts—are validated per IKA’s mechanical interface specifications and listed in the user manual. The instrument complies with DIN EN 60529 (IP21), IEC 61010-1 (Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory Use), and electromagnetic compatibility standards EN 61326-1. For regulated environments, its RS-232/USB logging capability supports 21 CFR Part 11-compliant electronic records when paired with validated third-party data acquisition software meeting ALCOA+ principles (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available).

Software & Data Management

While the MS 3 control operates autonomously via front-panel controls, its bidirectional serial interfaces enable external control and data capture. Through IKA Labworld (v3.0+), users can configure start/stop commands, monitor real-time speed deviation, log timestamped run sessions, and export CSV-formatted operation histories—including speed setpoint, actual rpm, duration, and mode selection—for GLP/GMP documentation. Audit trails are retained locally on host PC storage; no cloud transmission occurs unless explicitly configured by the end user. Firmware updates are delivered via USB stick and require physical confirmation to maintain system integrity.

Applications

• Resuspension of pelleted cells or lyophilized reagents in microcentrifuge tubes
• Uniform mixing of ELISA assay components during plate coating and washing steps
• Pre-incubation agitation of enzymatic reaction mixtures (e.g., restriction digests, ligations)
• Homogenization of viscous biological samples (e.g., tissue lysates, bacterial suspensions) prior to filtration or analysis
• Standardized agitation in stability studies per ICH Q5C guidelines where mechanical consistency directly impacts degradation kinetics
• Integration into automated liquid handling workcells where precise, repeatable shaking cycles are required between dispensing and detection steps

FAQ

What is the maximum load capacity—and does it include the weight of the clamp or adapter?
The rated maximum load of 0.5 kg includes the combined mass of the sample vessels, any mounted adapter plate, and associated clamps.
Can the MS 3 control be used inside a CO₂ incubator or cold room?
No—it is rated for ambient operation only (5–40 °C, non-condensing humidity). Enclosure within temperature- or humidity-controlled chambers voids warranty and risks condensation-induced electrical failure.
Is speed calibration traceable to national standards?
Yes—factory calibration is performed using NIST-traceable tachometric reference equipment; calibration certificates are available upon request with optional IQ/OQ documentation packages.
Does the device support password-protected parameter locking for shared lab environments?
No—the MS 3 control lacks user-level access control; however, configuration changes require physical interaction with front-panel buttons, mitigating accidental modification in multi-user settings.
How frequently should preventive maintenance be performed?
IKA recommends visual inspection of platform leveling and fastener integrity every 6 months; no scheduled lubrication or internal servicing is required due to brushless DC motor design and sealed bearing construction.
