Scientific Industries Vortex-Genie 2 Rotational Mixer (Model SI-0246)

Overview

The Scientific Industries Vortex-Genie 2 (Model SI-0246) is a precision-engineered orbital shaker designed for consistent, reproducible mixing of liquid samples in tubes, vials, microplates, and small-volume containers. Utilizing a robust cast-iron housing and a balanced eccentric drive mechanism, the instrument generates controlled circular orbital motion with a fixed 4.5 mm amplitude—optimized to induce efficient vortex formation across a wide range of viscosities and volumes without splashing or foaming. Unlike centrifugal or linear shakers, the Vortex-Genie 2 operates on the principle of orbital oscillation, where the platform rotates about a central axis while maintaining constant contact with the sample container base—ensuring uniform energy transfer and minimizing shear-induced degradation of sensitive biological materials. Its mechanical simplicity, absence of electronic speed feedback loops, and analog dial-based speed control contribute to long-term operational stability and minimal maintenance requirements—making it a foundational tool in clinical diagnostics, molecular biology, microbiology, and quality control laboratories worldwide.

Key Features

• Three-Position Power Switch: Enables seamless transition between OFF, TOUCH (momentary activation upon downward pressure), and ON (continuous operation) modes—supporting both rapid sample homogenization and extended incubation-compatible mixing.
• Variable-Speed Analog Control: Precision-machined dial allows fine-tuned adjustment from 600 rpm (gentle agitation for cell suspensions or enzyme reactions) to 3200 rpm (high-intensity vortexing for viscous lysates or particulate resuspension), with tactile feedback and repeatable setting recall.
• Structural Integrity: Fully cast-iron chassis (4 kg mass) combined with non-slip rubber feet ensures vibration damping and platform stability—even during high-speed operation with unbalanced loads or stacked accessories.
• Modular Accessory Ecosystem: Interchangeable platform inserts—including standard rubber cup, 3-inch flat platform, multi-well plate adapters, and tube-specific foam inserts—are mechanically compatible with all Vortex-Genie 2 units and support GLP-compliant documentation of mixing conditions.
• Regulatory Compliance Ready: Certified to UL 61010-1, CSA C22.2 No. 61010-1, and CE directives for laboratory equipment safety; compatible with ISO/IEC 17025-accredited workflows when used with validated accessories and documented operating parameters.

Sample Compatibility & Compliance

The Vortex-Genie 2 accommodates diverse sample formats without modification: single tubes (0.2–50 mL), conical centrifuge tubes, glass vials, PCR strips, 96-well microplates (with optional sponge mat), and small flasks (using elastic band adapter kits). All accessories—including the TurboMix Cell Disruption Kit (SI-0563)—are designed to maintain consistent mechanical coupling under variable thermal conditions (e.g., cold rooms or incubators at 4°C–37°C). Foam inserts are autoclavable (121°C, 20 min), and metal platforms resist corrosion from common solvents and buffers. For regulated environments, users may implement traceable speed verification using calibrated tachometers, and record settings per batch in audit-ready logbooks—aligning with FDA 21 CFR Part 11 expectations for manual instruments when integrated into broader QMS frameworks.

Software & Data Management

The Vortex-Genie 2 is a standalone electromechanical instrument with no embedded firmware or digital interface. As such, it does not require software installation, network connectivity, or cybersecurity protocols—reducing validation burden in GxP-regulated labs. Speed settings are manually selected and visually confirmed via the analog dial scale, supporting straightforward operator training and SOP-driven use. While no native data logging is provided, integration with external time-lapse imaging systems or programmable environmental chambers enables synchronized experimental tracking. Laboratories implementing electronic lab notebooks (ELNs) may document speed, duration, accessory type, and sample identifiers directly within protocol templates—ensuring full traceability without proprietary software dependencies.

Applications

• Resuspension of pelleted cells, bacterial colonies, or lyophilized reagents
• Homogenization of tissue lysates prior to nucleic acid or protein extraction
• Emulsification of immiscible phases in assay development (e.g., ELISA buffer preparation)
• Mixing of low-volume PCR/qPCR master mixes and reaction components
• Uniform dispersion of magnetic beads in automated nucleic acid purification workflows
• Cell disruption in combination with glass beads (TurboMix Kit) under chilled conditions
• Pre-analytical sample conditioning for HPLC, GC, or ICP-MS sample introduction systems

FAQ

Is the Vortex-Genie 2 suitable for use inside refrigerated incubators or cold rooms?
Yes—its fully mechanical design and absence of heat-generating electronics allow safe operation at ambient temperatures ranging from 4°C to 40°C, provided appropriate accessories (e.g., cold-rated foam inserts) are used.

Can the speed be calibrated or verified independently?
Yes—users may verify rotational speed using a non-contact optical tachometer aligned with the rotating platform edge; calibration certificates from third-party metrology labs are available upon request.

What maintenance is required for long-term reliability?
Routine cleaning of the platform surface and inspection of rubber feet for wear; no lubrication or internal servicing is required under normal use conditions.

Are replacement parts and accessories supplied with lot-specific traceability?
Yes—Scientific Industries provides serialized accessory kits (e.g., SI-0563, 504-0234) with manufacturer lot numbers and CoA documentation upon request for regulated applications.

Does the unit comply with electromagnetic compatibility (EMC) standards for shared laboratory environments?
Yes—certified to EN 61326-1 (2013) for EMC emission and immunity, ensuring stable performance alongside sensitive analytical instrumentation such as mass spectrometers or patch-clamp amplifiers.
