IKA Vortex 3 Compact Orbital Vortex Mixer

Overview

The IKA Vortex 3 Compact Orbital Vortex Mixer is an engineered solution for rapid, reproducible sample homogenization in routine laboratory workflows. Based on the principle of orbital eccentric motion—where a motor-driven eccentric shaft induces controlled circular displacement of the platform—the Vortex 3 delivers consistent mixing energy across diverse vessel geometries without requiring mechanical clamping or complex setup. Its 4 mm orbit diameter ensures efficient vortex formation in small-volume tubes while minimizing splashing and aerosol generation. Designed for high-duty-cycle environments—including QC labs, clinical diagnostics, molecular biology prep stations, and academic teaching labs—the mixer operates at full 100% duty cycle with thermally optimized motor ventilation, enabling uninterrupted operation during extended protocols such as cell suspension preparation or reagent resuspension.

Key Features

• Touch-activated instant start/stop functionality: Press down on any compatible platform or accessory to initiate mixing; release to halt—ideal for intermittent, operator-guided protocols.
• Continuously variable speed control (0–2500 rpm) via calibrated analog dial, offering precise adjustment without digital interface dependency.
• Robust die-cast zinc housing provides structural rigidity and electromagnetic shielding, contributing to long-term mechanical stability and reduced vibration transmission to adjacent instrumentation.
• Silicone-damped base feet absorb kinetic energy at high rotational speeds, ensuring stable placement on benchtops—even during vigorous mixing of dense or viscous samples.
• Eccentric ball-bearing drive mechanism ensures low-friction, low-noise operation and extends service life under continuous use conditions.
• Compliance with IEC/EN 60529 (IP21) safeguards against vertically falling solid objects and limited ingress of moisture—suitable for standard laboratory ambient conditions (5–40 °C, ≤80 % RH).

Sample Compatibility & Compliance

The Vortex 3 supports broad sample container versatility through a modular accessory system. Standard platform (VG 3.1) accommodates single tubes or flat-bottom vessels. Optional accessories include the VG 3.2 circular holder, VG 3.3 universal platform, and application-specific inserts: VG 3.31 (54 × Eppendorf® tubes), VG 3.32–3.35 (for 10–20 mm diameter tubes), VG 3.36 (conical flask clamp for up to 250 mL Erlenmeyer flasks), and VG 3.37 (single-position microplate adapter). All accessories mount securely without tools. The system meets general-purpose laboratory safety standards and is routinely deployed in environments adhering to GLP practices. While not inherently 21 CFR Part 11 compliant (lacking audit trail or electronic signature capability), its analog control architecture ensures operational transparency and traceability via manual log entries—a common implementation pathway in non-regulated or legacy-compliant workflows.

Software & Data Management

The IKA Vortex 3 operates as a standalone analog instrument with no embedded microprocessor, firmware, or digital connectivity (no RS232, USB, or analog output). Speed setting is manually observed via engraved scale—eliminating calibration drift associated with digital displays and reducing maintenance overhead. This design prioritizes reliability, ease of qualification (IQ/OQ), and compatibility with ISO/IEC 17025-accredited laboratories where deterministic, non-software-dependent operation is preferred. For labs requiring electronic documentation, external timing devices or integrated lab information management systems (LIMS) may be used to record run parameters and operator IDs per batch.

Applications

The Vortex 3 is routinely employed in nucleic acid extraction workflows (e.g., lysis buffer resuspension), immunoassay plate agitation prior to reading, bacterial culture resuspension, reagent reconstitution, and solvent mixing in analytical sample prep. Its compact footprint (127 × 136 mm) and low acoustic emission (<55 dB at 2500 rpm) make it suitable for laminar flow hoods, biosafety cabinets, and shared bench spaces. The ability to process microplates (via VG 3.37) supports ELISA, drug screening, and high-throughput assay support—particularly where gentle yet uniform agitation is required to prevent well-to-well cross-contamination.

FAQ

Does the Vortex 3 include a timer function?
No—the Vortex 3 does not feature an integrated timer. Timing must be managed externally using a stopwatch, lab timer, or LIMS-controlled protocol step.
Is the unit compatible with 100 V power supplies?
Yes—dual-voltage input (100–240 V, 50/60 Hz) enables global deployment without transformers.
Can the Vortex 3 accommodate conical flasks?
Yes—when fitted with the optional VG 3.36 conical flask clamp, it securely holds Erlenmeyer flasks up to 250 mL.
What is the maximum recommended continuous runtime?
The device is rated for 100% duty cycle and may operate continuously without thermal derating under specified ambient conditions (≤40 °C, ≤80 % RH).
Are replacement platforms and tube inserts available separately?
Yes—all accessories—including VG 3.31 through VG 3.37—are orderable as individual components with standardized IKA part numbers for seamless inventory management and replacement planning.
