IBI Scientific Hi/Lo Rocker Reciprocating Rocking Platform Shaker

Overview

The IBI Scientific Hi/Lo Rocker is a precision-engineered reciprocating rocking platform shaker designed for consistent, low-shear mixing in life science laboratories. Unlike orbital or vortex shakers, this device employs a controlled linear rocking motion—oscillating about a central pivot axis—to generate gentle yet effective agitation ideal for hybridization, staining, destaining, blotting, and immunoassay protocols. Its dual-platform architecture supports parallel processing across four independent 35 × 35 cm platforms, each fitted with a non-slip mesh mat to secure gels, blots, microplates, and glassware during operation. The instrument operates at ambient temperature without integrated heating or cooling, making it suitable for applications where thermal stability is not required but mechanical reproducibility is critical.

Key Features

• Four independently mounted rocking platforms, enabling simultaneous processing of multiple samples under identical mechanical conditions.
• Continuously adjustable oscillation speed from 0 to 22 rpm, calibrated for repeatable rotational velocity control via analog dial interface.
• Precisely tunable tilt angle between 2° and 11°, allowing optimization of fluid dynamics for diverse sample formats—from thin polyacrylamide gels to thick tissue sections.
• Robust aluminum-alloy frame and reinforced polymer housing ensure long-term mechanical stability and resistance to laboratory chemical exposure.
• Non-slip mesh mat included per platform to prevent lateral displacement of vessels during extended incubation cycles.
• Compact footprint (W × D × H: 45.7 × 40.6 × 12.7 cm) facilitates integration into biosafety cabinets, cold rooms, and shared benchtop environments.

Sample Compatibility & Compliance

The Hi/Lo Rocker accommodates standard laboratory consumables including mini-gel cassettes (up to 15 × 15 cm), Western blot transfer stacks, multi-well plates (6–96-well), Petri dishes, and glass staining trays. Each platform supports a maximum load of 9.07 kg (20 lbs), distributed evenly across the surface. The device meets UL 61010-1 safety requirements for laboratory electrical equipment and complies with IEC 61326-1 for electromagnetic compatibility in scientific environments. While not certified for GLP/GMP-regulated workflows out-of-the-box, its mechanical repeatability and absence of software-based control logic make it suitable for use within validated SOPs where manual parameter recording is maintained per FDA 21 CFR Part 11 documentation practices.

Software & Data Management

This is a manually operated, analog-controlled instrument with no embedded firmware, touchscreen interface, or data logging capability. All operational parameters—including speed, tilt angle, and runtime—are set physically via front-panel dials and monitored visually. Users are responsible for documenting settings and run durations externally using laboratory notebooks or LIMS-integrated forms. This design prioritizes reliability, serviceability, and regulatory transparency—eliminating potential audit concerns related to electronic record integrity or firmware validation. No drivers, firmware updates, or cloud connectivity are required or supported.

Applications

• Nucleic acid and protein gel electrophoresis: uniform buffer exchange during post-electrophoresis staining and destaining.
• Western and Southern blotting: consistent antibody and probe incubation with minimized membrane distortion.
• In situ hybridization: gentle rocking ensures probe penetration without disrupting tissue morphology.
• Cell culture maintenance: low-frequency agitation of suspension cultures in roller bottles or large-volume flasks.
• Antigen-antibody binding assays: optimized rocking profiles improve binding kinetics in ELISA plate wash steps.
• Enzyme reaction support: controlled agitation enhances substrate diffusion in immobilized enzyme assays.

FAQ

Does the Hi/Lo Rocker include a timer function?

No. The unit operates continuously until manually powered off. External timers or scheduled power strips may be used for timed protocols.
Can the platforms be removed or reconfigured?

Yes—each platform is secured with four M4 screws and can be detached for cleaning or replaced with custom fixtures (e.g., rack mounts for tube holders).
Is the rocker compatible with CO₂ incubators?

It is rated for operation up to 65 °C ambient temperature; however, internal humidity and CO₂ concentration may accelerate corrosion of metal components. Use inside incubators is not recommended unless housed in an enclosed, ventilated enclosure.
What maintenance is required?

Annual inspection of pivot bearings and drive belt tension is advised. Lubrication is not required—the gearmotor uses sealed lifetime grease.
Does IBI Scientific provide calibration documentation?

Calibration certificates are not supplied as standard. Users may verify speed and angle using external tachometers and digital inclinometers per ISO/IEC 17025-compliant procedures.
