IKA ROCKER 2D basic Rocking Platform Shaker

Overview

The IKA ROCKER 2D basic is a compact, microprocessor-controlled rocking platform shaker engineered for reproducible, low-shear mixing in life science and biotechnology laboratories. It operates on a fixed-angle rocking motion—8° tilt—with a linear oscillation amplitude of 30 mm, generating gentle yet effective fluid agitation ideal for cell culture maintenance, hybridization assays, blotting procedures, staining/destaining, and reagent equilibration. Unlike orbital or reciprocating shakers, the ROCKER 2D basic utilizes a smooth, sinusoidal rocking profile that minimizes foaming, cell shearing, and splashing—critical for sensitive biological samples such as adherent mammalian cells, fragile protein complexes, or low-volume nucleic acid preparations. Its brushless DC motor and closed-loop speed regulation ensure consistent rotational velocity across variable loads and input voltage fluctuations, delivering high reproducibility essential for GLP-compliant workflows and routine QC testing.

Key Features

• Gentle, fixed-angle (8°) rocking motion optimized for low-stress sample handling and uniform mixing without vortex formation
• Wide speed range: 5–80 rpm, adjustable in precise 1-rpm increments via intuitive touch-sensitive controls
• Stable performance under varying load conditions (up to 2 kg including clamps) and input voltage deviations (100–240 V, 50/60 Hz)
• Robust aluminum housing with non-slip rubber feet; designed for uninterrupted 24/7 operation in incubators or ambient lab environments
• LED-based 7-segment display provides real-time speed readout; no timer or programmable functions—engineered for simplicity and reliability
• IP21-rated enclosure ensures protection against vertically falling drips and solid objects >12.5 mm, suitable for standard laboratory and controlled-environment use
• Stackable platform design allows vertical integration of multiple units to conserve bench space—each unit adds only 30 mm in height when stacked

Sample Compatibility & Compliance

The ROCKER 2D basic accommodates a broad range of vessel formats—including Petri dishes, multi-well plates (6–96-well), staining trays, blotting cassettes, glass tubes, and custom containers—via optional IKA-compatible clamps and universal platforms. Its operational temperature range (4–50 °C) enables direct placement inside refrigerated incubators, CO₂ chambers, or ambient workstations without thermal derating. While the device itself does not include active temperature control, its stable mechanical design and low heat dissipation (24 W max) prevent interference with external environmental regulation systems. The unit complies with DIN EN 60529 (IP21), IEC 61010-1 (safety requirements for electrical equipment), and meets CE marking directives for laboratory instrumentation. It supports audit-ready documentation practices in regulated environments where traceability of mixing parameters is required per internal SOPs—though it lacks FDA 21 CFR Part 11–compliant electronic records functionality due to absence of data logging interfaces.

Software & Data Management

The ROCKER 2D basic is a standalone, hardware-only instrument with no embedded software, network connectivity, or digital interface. It features no USB, RS232, or analog output ports, and does not support remote configuration, firmware updates, or automated data capture. All operation is manual and local: users set speed via tactile buttons and verify output using the integrated LED display. This architecture eliminates cybersecurity risks, reduces validation complexity, and enhances long-term operational stability—making it particularly suited for ISO 13485-certified manufacturing labs, academic core facilities, and clinical research settings where deterministic behavior and minimal maintenance overhead are prioritized over digital integration.

Applications

• Western/Northern/Southern blotting: uniform buffer exchange and probe hybridization across membranes
• Cell culture maintenance: gentle agitation of suspension cultures or media replenishment in flasks and dishes
• Immunostaining and histochemistry: consistent antibody penetration and wash steps in tissue sections
• Molecular biology workflows: DNA/RNA binding, enzyme reaction equilibration, and gel staining/destaining
• Quality control in biopharmaceutical production: buffer preparation, dilution series mixing, and stability test sample agitation
• Educational laboratories: teaching fundamental principles of fluid dynamics and reproducible experimental technique

FAQ

Does the ROCKER 2D basic offer temperature control?
No. It is a non-thermostatic shaker designed for use within externally controlled environments (e.g., incubators). Its operating ambient range is 4–50 °C.
Can it be used inside a CO₂ incubator?
Yes—provided the incubator’s internal humidity and condensation levels remain within the unit’s specified limit (≤80 % RH) and physical clearance permits safe mounting.
Is speed calibration traceable to national standards?
While the device incorporates factory-calibrated speed feedback, it does not ship with a NIST-traceable calibration certificate. Users may perform periodic verification using an external tachometer per internal quality protocols.
What clamp options are available?
IKA offers universal platform inserts, multi-well plate holders, Petri dish clamps, and custom-fit adapters—all mechanically secured without tools and compatible with standard labware dimensions.
Does it support timed operation or programmable sequences?
No. The ROCKER 2D basic operates continuously at user-selected speed until manually powered off.
