Overview
The Scientific Industries Multi Vortex-Genie Orbital Shaker is an engineered solution for consistent, low-shear orbital mixing in life science laboratories. Designed around a precision-balanced eccentric drive mechanism, it delivers uniform circular motion with a 4 mm orbit diameter—optimized for efficient suspension of cells, reagents, and particulates without foaming or splashing. Unlike vortex mixers that apply high-shear localized agitation, the Multi Vortex-Genie operates on orbital kinematics, generating gentle yet effective mixing across heterogeneous samples in tubes, flasks, microplates, and open vessels. Its robust aluminum-alloy housing and vibration-damped base ensure stable performance during extended runs, while the digitally controlled interface enables repeatable protocol execution essential for QC workflows, cell culture preparation, ELISA plate washing, and sample homogenization prior to downstream analysis (e.g., PCR, spectrophotometry, or HPLC injection).
Key Features
- Digital speed and timer control with ±2 rpm accuracy and <±0.5% speed stability over time—critical for method reproducibility in regulated environments.
- Orbital motion with fixed 4 mm orbit diameter ensures predictable fluid dynamics across vessel geometries, minimizing wall adhesion and sedimentation in low-viscosity aqueous solutions.
- Zinc-plated steel support feet provide enhanced surface grip and mechanical isolation, reducing lateral displacement on benchtops—even during high-speed operation at 1000 rpm.
- Adjustable universal clamp system accommodates a wide range of container formats: 0.5 L Erlenmeyer flasks, 96-well plates (including deep-well variants), 15/50 mL conical tubes, and open beakers—without requiring additional accessories.
- No external cooling or heating module required; designed for ambient-temperature operation only, eliminating thermal drift concerns during short-duration mixing protocols.
- CE-certified construction complies with IEC 61000-6-2 (immunity) and IEC 61000-6-3 (emissions), supporting integration into ISO 17025-accredited testing labs.
Sample Compatibility & Compliance
The Multi Vortex-Genie supports direct mixing of samples in both sealed and open containers, making it suitable for applications where gas exchange is necessary (e.g., aerobic bacterial culture resuspension or CO₂-sensitive buffer equilibration). Its orbital design avoids aerosol generation common with vortexing—reducing cross-contamination risk in shared biosafety cabinets. The shaker meets general laboratory safety requirements per EN 61010-1 and is compatible with GLP-compliant documentation practices when paired with lab notebook entries or electronic logbooks. While not temperature-controlled, its ambient-only operation aligns with USP guidance for non-critical mixing equipment used in analytical sample preparation.
Software & Data Management
This model operates via standalone digital controls—no software driver, USB interface, or PC connectivity is included or required. All operational parameters (speed and timer) are set manually using front-panel push-button inputs and a dual-digit LED display. This architecture eliminates cybersecurity vulnerabilities associated with networked instruments and simplifies validation under FDA 21 CFR Part 11 Annex 11 frameworks, as no electronic records or audit trails are generated. For labs implementing paper-based SOPs, the absence of firmware updates or configuration files streamlines IQ/OQ documentation and reduces requalification burden.
Applications
- Resuspension of lyophilized reagents and bacterial pellets prior to centrifugation or dilution.
- Homogenization of immunoassay plates (ELISA, CLIA) to ensure uniform antigen-antibody binding kinetics.
- Pre-analytical mixing of clinical specimens (serum, plasma, urine) before automated analyzer loading.
- Cell dissociation support in primary culture workflows, particularly for adherent lines requiring gentle detachment.
- Buffer equilibration and pH adjustment in protein purification steps involving ion-exchange chromatography.
- Standardization of particle dispersion in nanoparticle formulation studies prior to DLS or TEM analysis.
FAQ
Is the Multi Vortex-Genie suitable for use inside a CO₂ incubator?
No. It is rated for ambient-temperature operation only and lacks environmental sealing or temperature-rated components.
Can the shaker accommodate 384-well microplates?
Yes—the adjustable clamp system allows secure fixation of standard SBS-format plates, including 384-well designs, provided they are placed centrally on the platform.
Does the device support programmable multi-step protocols?
No. It offers single-stage speed and timer settings only; complex sequences require external timing coordination.
What maintenance is required for long-term reliability?
Annual inspection of drive belt tension and bearing play is recommended; no lubrication is required due to sealed ball-bearing construction.
Is the CE marking valid for UKCA compliance?
No. CE marking does not automatically confer UKCA approval; separate conformity assessment is required for placement in Great Britain markets.
