IKA MS3 Vortex Mixer

Overview

The IKA MS3 Vortex Mixer is a compact, analog-digital hybrid benchtop vortex shaker engineered for reproducible, low-volume sample homogenization in life science laboratories. It operates on the principle of orbital shaking—generating controlled circular motion with a fixed 4.5 mm orbit diameter—to induce rapid fluid agitation in tubes, microcentrifuge vials, and standard 96-well microplates. Unlike high-throughput orbital shakers or temperature-controlled incubator shakers, the MS3 is purpose-built for intermittent, operator-initiated mixing tasks where speed stability, mechanical robustness, and intuitive operation are prioritized over programmability or environmental control. Its design targets routine applications including reagent resuspension, cell suspension preparation, ELISA plate pre-incubation mixing, and PCR tube vortexing prior to centrifugation. The unit functions exclusively at ambient laboratory temperature and does not integrate heating or cooling modules.

Key Features

• Two-mode operational logic: Mode A (Safety Mode) enforces automatic pad detection—when used with IKA-certified standard vortex pads, maximum speed is limited to 3000 rpm; with non-standard or third-party pads, speed is capped at 1300 rpm to prevent mechanical overload or sample splashing.
• Mode B (Unrestricted Mode) bypasses pad recognition, enabling full 0–3000 rpm speed range regardless of pad type—intended for experienced users performing validated protocols under controlled conditions.
• Dual-action control interface: tactile toggle switch supports both continuous operation and momentary “touch” mode for precise, short-duration mixing without timer engagement.
• High-stability drive mechanism with cast-iron, zinc-coated housing ensures vibration damping and long-term rotational consistency across the entire speed range.
• Dedicated LED digital timer with 1-minute resolution and auto-countdown functionality; supports timing up to 999 minutes (16 h 39 min), with audible end-of-timer alert.
• Analog speed scale (0–3000 rpm) provides immediate visual feedback; no software calibration or firmware updates required.

Sample Compatibility & Compliance

The MS3 accommodates common labware via interchangeable vortex pads—including conical tube holders (0.2–50 mL), microplate adapters (96-well flat-bottom or U/V-bottom), and universal rubber pads for irregular containers. Maximum load per platform is 0.5 kg, ensuring safe operation with up to four 15-mL conical tubes or one full 96-well plate. While the device itself carries CE marking per EU Directive 2014/30/EU (EMC) and 2014/35/EU (LVD), it is not certified for use in ISO Class 5 cleanrooms or classified as medical device (MDR 2017/745). It complies with general laboratory safety standards (IEC 61010-1) and supports GLP-aligned workflows when paired with documented SOPs and manual log entries. No built-in audit trail or electronic record capability is provided; therefore, it is not compliant with FDA 21 CFR Part 11 requirements for regulated environments unless integrated into a validated external data capture system.

Software & Data Management

The IKA MS3 is a stand-alone, hardware-only instrument with no embedded microprocessor, USB port, Bluetooth, or network interface. All operation is performed manually via front-panel controls. Speed and timer settings are not stored or exportable. Data integrity relies entirely on user documentation: operators must record speed setting, duration, pad type, and sample configuration in laboratory notebooks or LIMS-compatible forms. For laboratories requiring traceable mixing parameters, integration with external time-stamped video monitoring or IoT-enabled power-meter logging (e.g., via smart plug analytics) may be implemented at the facility level—but such configurations fall outside the scope of IKA’s factory validation.

Applications

• Routine resuspension of lyophilized enzymes, antibodies, and oligonucleotides in low-volume buffers (≤1 mL).
• Homogenization of bacterial or mammalian cell pellets prior to lysis buffer addition.
• Pre-centrifugation mixing of blood serum samples in EDTA or heparin tubes.
• Equilibration of immunoassay reagents on microplates before optical density measurement.
• Accelerated dissolution testing of solid-phase extraction (SPE) cartridges during method development.
• Quality control checks in raw material receipt—verifying uniformity of powder suspensions or colloidal dispersions.

FAQ

Does the MS3 support temperature-controlled mixing?
No. The MS3 operates exclusively at ambient temperature and contains no thermal regulation components.
Can I use non-IKA vortex pads with this mixer?
Yes—however, in Mode A, non-standard pads limit maximum speed to 1300 rpm; in Mode B, full 3000 rpm is available, but mechanical compatibility and sample containment must be verified by the user.
Is the timer battery-backed?
No. The LED timer resets to zero upon power interruption; no volatile memory is included.
What maintenance is required?
Periodic cleaning of the platform surface and pad contact area with 70% ethanol; no lubrication or internal servicing is recommended or supported under warranty.
Is the MS3 suitable for GMP-regulated environments?
It may be used in GMP facilities only as a secondary, non-critical mixing tool—provided its use is fully documented, calibrated annually against a traceable tachometer, and excluded from automated batch records.
