SI MicroPlate Genie Orbital Microplate Shaker

Overview

The SI MicroPlate Genie Orbital Microplate Shaker is an engineered solution for precise, reproducible mixing of samples in standard SBS-format microplates (96-, 384-, and 1536-well). Designed specifically for life science, clinical diagnostics, and pharmaceutical R&D laboratories, it employs controlled circular orbital motion to generate uniform agitation without splashing or cross-contamination. Unlike vortex mixers that induce high-shear localized turbulence, the MicroPlate Genie delivers gentle yet effective homogenization via a consistent 1 mm orbit diameter—optimized for maintaining cell viability, enzyme activity, and immunoassay integrity during incubation or binding steps. Its compact footprint (165 × 165 × 165 mm), lightweight polycarbonate construction, and robust DC motor ensure stable operation across extended protocols, including overnight shaking at low-to-moderate speeds.

Key Features

• Adjustable speed control from 750 to 3200 RPM, calibrated for both 50 Hz and 60 Hz power systems (2700 RPM max for 50 Hz models)
• Circular orbital motion with precisely maintained 1 mm orbit diameter—minimizes sample foaming and well-to-well variability
• Polycarbonate housing providing chemical resistance, impact durability, and compatibility with common lab disinfectants (e.g., 70% ethanol, diluted sodium hypochlorite)
• Analog speed scale for intuitive, tool-free parameter verification—no battery or digital interface required
• Standard SBS-compliant platform accommodates all commercially available microplates, including skirted, semi-skirted, and unskirted formats
• Low-noise operation (<55 dB(A) at 1 m) suitable for shared lab environments and biosafety cabinets
• Thermally stable motor design enabling continuous-duty operation without thermal shutdown

Sample Compatibility & Compliance

The MicroPlate Genie supports a broad range of assay formats, including ELISA, cell-based assays, nucleic acid hybridization, protein binding studies, and plate-based enzymatic reactions. Its mechanical design conforms to ANSI/SBS standards for microplate dimensional tolerances (ANSI SLAS 1–4), ensuring repeatable positioning and minimal lateral drift. While the device itself does not require FDA clearance as a Class I exempt instrument, its performance characteristics align with GLP and GMP documentation requirements when integrated into validated workflows. Laboratories performing ISO/IEC 17025-accredited testing may include the MicroPlate Genie in equipment qualification protocols (IQ/OQ) using manufacturer-provided calibration data and traceable speed verification methods.

Software & Data Management

As a standalone analog shaker, the MicroPlate Genie operates without embedded firmware or connectivity interfaces. This architecture eliminates cybersecurity vulnerabilities, reduces validation overhead, and ensures deterministic behavior under regulated conditions. For labs requiring audit trails, users may integrate external timers or programmable power controllers compliant with FDA 21 CFR Part 11 (e.g., validated LabTimer modules with electronic signature capability). The absence of software dependencies simplifies requalification after maintenance and avoids obsolescence risks associated with discontinued OS support or driver updates.

Applications

• Antibody-antigen binding kinetics in ELISA and multiplex immunoassays
• Cell suspension maintenance during staining or washing steps in flow cytometry workflows
• Homogenization of viscous lysates prior to centrifugation or filtration
• Enhancing hybridization efficiency in microarray and in situ hybridization protocols
• Facilitating uniform crystal seeding in high-throughput crystallization screens
• Supporting dissolution testing of solid dosage forms in 96-well plate-based USP Apparatus IV simulations

FAQ

Is the MicroPlate Genie compatible with PCR plates and deep-well plates?
Yes—it accepts any microplate conforming to the SBS footprint specification (127.76 × 85.48 mm), including PCR plates (with or without optical seals) and 96-well deep-well blocks (up to 2.2 mL capacity).
Does it support timed operation?
No—the base MicroPlate Genie model lacks a built-in timer; it operates continuously once powered. For time-limited protocols, external mechanical or electronic timers are recommended.
Can it be used inside a cold room or incubator?
Yes—its polycarbonate housing and brushless DC motor are rated for ambient operation between 4 °C and 40 °C and relative humidity up to 80% non-condensing.
What maintenance is required?
Routine cleaning with lint-free cloths and 70% isopropyl alcohol; no lubrication or calibration is necessary due to the fixed-orbit mechanical design.
Is speed accuracy traceable to NIST standards?
While the unit is factory-calibrated using certified tachometric reference instruments, formal NIST-traceable calibration certificates are available upon request through authorized service partners.
