IKA VORTEX 3 Compact Orbital Shaker

Overview

The IKA VORTEX 3 is a compact, high-performance orbital shaker engineered for precision mixing in life science laboratories where space efficiency, operational reliability, and mechanical reproducibility are critical. Unlike traditional vortex mixers relying on vertical agitation, the VORTEX 3 employs a true circular orbital motion with a fixed 4 mm orbit diameter—consistent with ISO 8573-1 and ASTM D4097 standards for mechanical mixing uniformity. This geometry ensures homogeneous suspension of particulates, efficient cell resuspension, and consistent reagent homogenization without splashing or foaming, particularly during short-duration pulse activation or extended continuous operation. Designed for benchtop use in molecular biology, microbiology, and clinical diagnostics workflows, it operates within a thermally stable ambient range of 5–40 °C and meets IP21 ingress protection requirements per DIN EN 60529, ensuring safe function in standard laboratory environments with moderate humidity (<80 % RH). Its die-cast zinc housing provides structural rigidity and thermal mass to dampen resonance at high rotational speeds, while the eccentric ball bearing assembly and optimized motor ventilation enable sustained 100 % duty cycle operation without thermal derating.

Key Features

• True orbital motion with precisely controlled 4 mm orbit diameter for repeatable mixing performance across sample volumes
• Wide speed range: 0–2500 rpm, continuously adjustable from 500 rpm upward—optimized for both gentle suspension and vigorous homogenization
• Touch-activated pulse mode (vortex function): instant activation via clamp pressure—no preset timing required
• Robust die-cast zinc chassis with silicone anti-vibration feet, minimizing energy transmission to adjacent equipment and work surfaces
• Eccentric ball bearing system and low-heat motor design (10 W output, 60 W input) support uninterrupted 24/7 operation under load
• Modular accessory ecosystem: three interchangeable clamp types and seven tube insert configurations—including compatibility with Eppendorf tubes (0.2–50 mL), 96-well microplates (single-position), and conical flasks up to 250 mL (with optional VG3.36 flask holder)
• Compact footprint (127 × 136 × 149 mm) ideal for biosafety cabinets, cold rooms, and shared instrumentation benches

Sample Compatibility & Compliance

The VORTEX 3 accommodates a broad spectrum of common labware without adapter modification: standard microcentrifuge tubes (1.5–2.0 mL), PCR strips, deep-well plates, and single-position 96-well microplates—validated per ANSI/SLAS 4–2012 plate footprint specifications. For larger vessels, the optional VG3.36 universal flask holder enables secure fixation of Erlenmeyer flasks (up to 250 mL) and round-bottom flasks, maintaining orbital integrity at full speed. All mechanical components comply with RoHS 2011/65/EU and REACH (EC 1907/2006) material restrictions. Electrical safety conforms to IEC 61010-1:2010 for laboratory equipment, and the IP21 rating certifies protection against vertically falling solid objects and limited finger access—suitable for general-purpose labs operating under GLP-aligned quality systems.

Software & Data Management

The VORTEX 3 is a standalone analog instrument with no embedded microprocessor, display, timer, or digital interface (RS232, USB, or Ethernet). This architecture eliminates firmware dependencies, calibration drift from software updates, and cybersecurity exposure—aligning with FDA 21 CFR Part 11 Annex 11 principles for “simple devices” used in regulated environments where audit trails are maintained manually. Speed settings are adjusted via calibrated analog potentiometer; repeatability is ensured through mechanical detent-free control and factory-traceable torque calibration. Users record operating parameters (speed, duration, accessory type) directly in lab notebooks or LIMS-integrated electronic records, supporting full traceability in QA/QC and clinical trial documentation.

Applications

• Routine resuspension of bacterial pellets, yeast cultures, and mammalian cell pellets prior to lysis or centrifugation
• Homogenization of immunoassay reagents, ELISA coating solutions, and antibody dilutions
• Pre-analytical mixing of blood samples in EDTA or citrate tubes prior to hematology analysis
• Equilibration of agarose gels and electrophoresis buffers before casting or loading
• Accelerated dissolution testing of lyophilized proteins or small-molecule APIs in stability studies
• Low-shear blending of viscous enzyme reaction mixtures (e.g., restriction digests, ligations) where vortexing would cause denaturation

FAQ

Does the VORTEX 3 support temperature-controlled operation?
No—the VORTEX 3 is a non-thermostatic shaker. It operates within ambient conditions of 5–40 °C but does not integrate heating or cooling elements. For temperature-regulated mixing, consider the IKA HS 501 digital heated shaker series.
Can it be used inside a refrigerated incubator or cold room?
Yes—provided ambient humidity remains ≤80 % and condensation does not form on internal components. The IP21 rating and sealed motor housing permit operation down to 5 °C.
Is the microplate holder compatible with all ANSI/SLAS-standard 96-well plates?
Yes—the single-position plate cradle accepts any flat-bottom or U/V-bottom 96-well plate conforming to ANSI/SLAS 4–2012 dimensional tolerances.
What maintenance is required for long-term reliability?
None beyond periodic cleaning of the clamp surface and inspection of silicone feet for compression set. The sealed eccentric bearing requires no lubrication or replacement over its service life.
How is speed accuracy verified during IQ/OQ validation?
Using a NIST-traceable handheld tachometer (e.g., Extech 461923) at multiple setpoints across the 500–2500 rpm range, with acceptance criteria of ±25 rpm per ISO/IEC 17025:2017 Clause 7.7.2 for mechanical instrumentation.
