Scientific Industries Vortex-Genie 2 Variable-Speed Vortex Mixer

Overview

The Scientific Industries Vortex-Genie 2 is a precision-engineered orbital vortex mixer designed for consistent, reproducible sample homogenization in research, clinical, and quality control laboratories. Utilizing a robust eccentric drive mechanism, it generates controlled circular orbital motion—distinct from linear shaking or magnetic stirring—to induce rapid, turbulent mixing within liquid samples contained in tubes, vials, microplates, and flasks. Its mechanical architecture delivers high torque across the full speed range (0–3200 rpm), enabling effective suspension of particulates, resuspension of pellets, emulsification of immiscible phases, and uniform dispersion of reagents without introducing shear-sensitive degradation. The device operates on a fundamental principle of forced harmonic oscillation, where rotational energy is translated into lateral displacement (4.5 mm amplitude) to maximize interfacial contact between sample components. As a globally recognized benchmark in benchtop mixing instrumentation, the Vortex-Genie 2 meets the functional expectations of ISO/IEC 17025-accredited labs and supports routine compliance with USP , CLSI EP10, and ASTM D4097 protocols for mixing validation.

Key Features

• Three-position power switch enables seamless transition between continuous operation (ON), touch-activated mode (TOUCH), and OFF—eliminating manual start/stop cycling and enhancing workflow efficiency.
• High-inertia die-cast metal base and flame-retardant ABS housing provide exceptional mechanical stability during high-speed operation, minimizing vibration transmission to adjacent equipment.
• Analog speed dial with calibrated scale allows intuitive, repeatable speed selection without digital dependency—ideal for environments requiring electromagnetic interference (EMI) resilience or simplified SOP execution.
• Dual-platform compatibility: accepts both single-tube holders (for 10–18 mm OD tubes) and 76-mm rubber flat platforms, supporting broad container geometry coverage without tooling changes.
• No maintenance motor design with sealed ball bearings ensures long-term operational reliability under daily use conditions typical of GLP/GMP-regulated facilities.

Sample Compatibility & Compliance

The Vortex-Genie 2 accommodates a wide spectrum of laboratory vessels—including polypropylene, glass, and polycarbonate tubes (10–37 mm OD), 96-well microtiter plates, conical centrifuge tubes, and small-volume flasks—via optional accessory kits (e.g., H301 Multi-Sample Kit, H302 Large-Sample Kit). All accessories are chemically resistant and autoclavable (up to 121°C, 20 min), ensuring compatibility with sterile processing workflows. The instrument complies with UL 61010-1, CSA C22.2 No. 61010-1, and EN 61010-1 safety standards for electrical laboratory equipment. Its analog interface and absence of embedded software exempt it from FDA 21 CFR Part 11 electronic record requirements—making it suitable for audit-ready environments where traceability is maintained via procedural documentation rather than digital logs.

Software & Data Management

The Vortex-Genie 2 operates as a standalone electromechanical device with no integrated firmware, cloud connectivity, or data logging capability. This design philosophy prioritizes operational simplicity, regulatory transparency, and long-term serviceability—particularly advantageous in regulated settings where validation burden must be minimized. Speed settings are manually selected and recorded in lab notebooks or electronic lab notebooks (ELNs) as part of standard operating procedures. For users requiring integration into automated workflows, the device’s stable mechanical output permits synchronization with programmable timers or PLC-controlled staging systems via external relay triggers (not included).

Applications

• Routine resuspension of bacterial cell pellets, lyophilized reagents, and antibody conjugates prior to assay setup.
• Homogenization of viscous biological matrices (e.g., whole blood, serum, tissue homogenates) for downstream ELISA, PCR, or flow cytometry analysis.
• Pre-analytical mixing in clinical chemistry, hematology, and toxicology labs—validated for use with CLIA-waived and moderate-complexity testing protocols.
• QC/QA sampling preparation in pharmaceutical manufacturing, including dissolution media conditioning and excipient dispersion verification per USP .
• Academic teaching labs where durability, ease of instruction, and multi-user accessibility are critical success factors.

FAQ

What is the difference between “Touch” and “Continuous” modes?
In Touch mode, the unit activates only when downward pressure is applied to the platform—ideal for intermittent mixing of temperature-sensitive or volatile samples. In Continuous mode, the mixer runs unattended at the selected speed until manually switched off.
Can the Vortex-Genie 2 be used with microplates?
Yes—when paired with the optional H301 Microplate Adapter (60-well or 96-well compatible), the device provides uniform agitation across all wells without cross-contamination risk.
Is calibration required for routine use?
While not mandated by regulatory bodies for qualitative mixing tasks, periodic verification of speed accuracy using a certified tachometer is recommended for quantitative applications; calibration certificates are available upon request from authorized distributors.
Does the unit support 220V/50Hz operation in Europe and Asia?
Yes—the Vortex-Genie 2 is factory-configured for universal voltage input (220–230 V, 50/60 Hz); no internal modification or external transformer is needed.
How does the 4.5 mm amplitude impact mixing efficiency?
This fixed orbital displacement optimizes kinetic energy transfer across common tube geometries—maximizing vortex formation in 15 mL conical tubes while preventing splashing in 1.5 mL microcentrifuge tubes at equivalent rpm settings.
