IKA MS3 Digital Orbital Shaker

Overview

The IKA MS3 Digital Orbital Shaker is a compact, precision-engineered benchtop shaker designed for consistent and reproducible orbital motion in life science laboratories. Utilizing a robust brushless DC motor and a balanced eccentric drive mechanism, it delivers stable circular oscillation with a fixed 4.5 mm orbit diameter—optimized for uniform mixing of low-volume samples in microtubes, PCR tubes, and standard 96-well microplates. Its cast-iron galvanized housing ensures mechanical stability and long-term operational integrity under continuous use. The device operates without integrated temperature control (i.e., ambient-only operation), making it suitable for applications where thermal regulation is managed externally or not required—such as enzymatic assays, cell suspension preparation, immunoassay plate washing, and reagent homogenization. Designed and manufactured in Germany to stringent DIN EN 60529 (IP21) safety standards, the MS3 Digital complies with IEC 61010-1 for laboratory electrical equipment.

Key Features

• Digital LED display with intuitive seven-segment timer and speed readout, supporting precise parameter setting and real-time monitoring
• Two operational modes: Mode A (safety mode with intelligent pad detection) limits max speed to 3000 rpm only when using certified IKA-standard pads; Mode B enables full 3000 rpm across all compatible accessories (e.g., microplate holders, tube clamps)
• Programmable timer with adjustable range from 1 minute to 999 minutes, plus countdown functionality and visual/audible end-of-cycle alert
• Three activation options: continuous operation, timed run, and momentary “pulse” mode for quick mixing verification
• Stable speed control from 200 rpm minimum to 3000 rpm maximum, with <±2% speed accuracy across the full range
• Low-power consumption design: 20 W input power, 8 W motor output, enabling energy-efficient operation during extended protocols
• Compact footprint (148 × 205 × 63 mm) and lightweight construction (2.9 kg) facilitate placement in biosafety cabinets, cold rooms, or crowded benchtop environments

Sample Compatibility & Compliance

The MS3 Digital accommodates common microscale sample containers—including 0.2–2.0 mL microcentrifuge tubes, PCR strips, and single or stacked 96-well microplates—when used with appropriate IKA-certified adapters (sold separately). Maximum payload capacity is 0.5 kg inclusive of fixture weight, ensuring mechanical resonance remains within safe operational thresholds. All mechanical and electrical components meet CE marking requirements and conform to ISO 13485-aligned manufacturing practices. While the unit itself does not incorporate active heating or cooling, its ambient operating range (5–40 °C) and humidity tolerance (≤80% RH, non-condensing) support integration into controlled laboratory environments compliant with GLP and ISO/IEC 17025 documentation frameworks.

Software & Data Management

The MS3 Digital operates as a standalone instrument without embedded software or network connectivity. It features no RS-232, USB, or analog output interfaces—ensuring electromagnetic compatibility in sensitive instrumentation zones and eliminating cybersecurity or data integrity concerns associated with connected devices. All parameters are set and verified locally via front-panel controls and LED indicators. For laboratories requiring audit-ready records, users may integrate the shaker into electronic lab notebook (ELN) workflows manually or via external time-lapse logging systems. No FDA 21 CFR Part 11 compliance features are included, as the device performs no data acquisition or storage functions—consistent with its classification as a Class I general-purpose laboratory accessory per IEC 61010-1.

Applications

• Homogenization of viscous biological samples prior to centrifugation or filtration
• Optimized incubation-mixing of ELISA, lateral flow assay, and chemiluminescence substrates
• Cell dissociation and suspension maintenance in non-adherent culture workflows
• Pre-analytical sample preparation for HPLC, mass spectrometry, and NGS library construction
• Quality control mixing steps in pharmaceutical QC labs following USP & EP guidelines
• Routine buffer equilibration, antibody dilution, and enzyme reaction setup in academic and industrial research settings

FAQ

Does the MS3 Digital include temperature control?
No. It is an ambient-only orbital shaker. Temperature-sensitive applications require external environmental control (e.g., cold room or incubator integration).
Can I use third-party microplate adapters with this shaker?
Yes—but only in Mode B. In Mode A, only IKA-certified pads trigger full-speed operation; non-certified accessories limit speed to 1300 rpm for safety.
What is the minimum usable speed, and how precisely can it be adjusted?
The lowest selectable speed is 200 rpm, with incremental adjustment in 10-rpm steps across the full 0–3000 rpm range.
Is the MS3 Digital suitable for GMP-regulated environments?
It may be deployed in GMP facilities as a utility-grade mixing tool, provided user-defined SOPs document calibration intervals, performance verification (e.g., speed/timer accuracy checks), and maintenance logs per Annex 15 expectations.
How is mechanical stability ensured at high speeds?
Through a rigid cast-iron base, precision-balanced drive shaft, and optimized center-of-gravity geometry—validated by IKA’s internal vibration testing at 3000 rpm under maximum load conditions.
