SI Genie-2 Vortex Mixer

Overview

The SI Genie-2 Vortex Mixer is a precision-engineered, benchtop orbital shaker designed for reproducible sample homogenization, resuspension, and emulsification across diverse laboratory workflows. Utilizing a robust eccentric drive mechanism, the Genie-2 generates controlled orbital motion—combining high-frequency vibration with rotational vortex action—to ensure thorough mixing of viscous, particulate-laden, or low-volume samples in tubes, vials, microplates, and conical containers. Its dual-mode operation (continuous or touch-activated momentary mode) enables both hands-free batch processing and precise, operator-initiated agitation—critical for applications requiring consistent timing, such as enzymatic reactions, cell lysis preparation, or reagent reconstitution. Engineered for long-term reliability in high-throughput QC labs, academic core facilities, and clinical diagnostics environments, the Genie-2 meets the mechanical durability and operational consistency expectations of ISO/IEC 17025-accredited laboratories.

Key Features

• Two-Mode Operation: Toggle between continuous orbital mixing and instant-on touch activation via a three-position rocker switch—eliminating unnecessary runtime and enhancing protocol repeatability.
• Wide Speed Range: Adjustable from 600 to 3200 rpm with fine-grained analog control and real-time LED linear bar graph feedback—enabling optimization for delicate suspensions (e.g., antibody conjugates) and aggressive dispersion (e.g., soil extracts or polymer solutions).
• Hybrid Motion Profile: Integrates orbital vortexing with vertical vibration amplitude modulation—improving mixing efficiency for heterogeneous samples that resist conventional vortex-only agitation.
• Die-Cast Metal Construction: Fully enclosed aluminum alloy housing with non-slip rubber feet ensures mechanical stability during high-speed operation and dampens transmission of vibration to adjacent instrumentation.
• Programmable Timer: Digital 1–99 second countdown timer with audible end-of-cycle alert supports standardized SOP execution and minimizes inter-operator variability.
• Modular Accessory Compatibility: Designed to accept a full suite of SI-certified platforms—including 3-inch flat pads, cup holders, microplate adapters, and tube racks—facilitating seamless transition between sample formats without recalibration.

Sample Compatibility & Compliance

The Genie-2 accommodates standard laboratory vessels including 0.2–50 mL conical tubes, 1.5–2.0 mL microcentrifuge tubes, PCR strips, 96-well plates (with optional adapter), and glass vials up to 25 mm diameter. Its vibration-isolated base prevents cross-contamination of adjacent instruments and complies with general laboratory safety standards (ANSI Z535.4, IEC 61010-1). While not classified as a medical device under FDA 21 CFR Part 820, the mixer supports GLP/GMP-aligned workflows through traceable operation logs (when integrated with external data capture systems) and adherence to routine maintenance intervals outlined in SI’s Technical Service Bulletin TS-VM-02.

Software & Data Management

The Genie-2 operates as a standalone hardware platform with no embedded firmware or network interface. All parameter settings—including speed, timer duration, and mode selection—are manually configured and retained only during active power supply. For audit-trail requirements in regulated environments, integration with Laboratory Information Management Systems (LIMS) or electronic lab notebooks (ELN) is achieved via external time-stamped video recording, manual log entry, or optional RS-232/USB-to-serial interface modules (sold separately, model VM-IO-01). SI provides calibration verification templates aligned with ISO/IEC 17025 Clause 6.5.2 for speed accuracy and timer deviation assessment.

Applications

• Biological Sample Preparation: Resuspension of lyophilized proteins, homogenization of bacterial pellets, and uniform dispersion of magnetic beads in nucleic acid isolation protocols.
• Clinical Diagnostics: Mixing whole blood specimens prior to centrifugation, reconstituting calibrators and controls for immunoassays, and agitating coagulation test tubes per CLSI H20-A2 guidelines.
• Pharmaceutical QC: Blending excipients in pre-formulation studies, dispersing nanoparticles in suspension formulations, and ensuring homogeneity of reference standards before HPLC injection.
• Environmental & Food Testing: Extraction of pesticides from plant matrices, homogenization of soil slurry samples for metal analysis, and emulsification of fat-soluble vitamins in fortified beverages.

FAQ

Is the Genie-2 suitable for use with volatile organic solvents?
Yes—the die-cast metal housing and sealed motor assembly are compatible with common laboratory solvents including ethanol, acetone, and chloroform when used in well-ventilated areas; however, prolonged exposure to strong oxidizers (e.g., concentrated nitric acid) is not recommended.
Does the Genie-2 support FDA 21 CFR Part 11 compliance?
No—the unit lacks electronic user authentication, audit trail generation, or electronic signature capability; however, it may be deployed within Part 11-compliant workflows when paired with validated external documentation systems.
What maintenance is required for long-term performance?
Annual inspection of the eccentric drive coupling and lubrication of the bearing assembly per SI Maintenance Guide MG-VM-03 is recommended; no routine calibration is required unless speed or timer deviation exceeds ±3% of setpoint.
Can the Genie-2 accommodate deep-well plates?
Yes—with the optional Deep-Well Plate Adapter (SI part #ADP-DWP-01), which maintains orbital integrity for 96- and 384-well formats containing up to 2 mL per well.
Is there a CE mark on this instrument?
Yes—the Genie-2 carries CE marking under the EU Machinery Directive 2006/42/EC and Electromagnetic Compatibility Directive 2014/30/EU, with full Declaration of Conformity available upon request from SI Technical Support.
