IKA ROCKER 2D basic Rocking Mixer

Overview

The IKA ROCKER 2D basic is a compact, microprocessor-controlled rocking mixer engineered for gentle, reproducible horizontal oscillation in life science laboratories. It operates on a fixed 8° tilt angle and delivers smooth sinusoidal motion across a precisely regulated speed range of 5–80 rpm (adjustable in 1-rpm increments), enabling consistent sample agitation without shear-induced denaturation or foaming—critical for cell culture maintenance, immunoassay incubation, blotting procedures, and low-viscosity reagent mixing. Unlike orbital or vortex shakers, the ROCKER 2D basic employs a linear rocking mechanism that minimizes centrifugal forces and ensures uniform suspension of particulates, gels, or membranes in shallow vessels. Its robust AC motor with integrated speed regulation maintains constant oscillation frequency even under variable load conditions or minor line voltage fluctuations—a key requirement for GLP-compliant workflows where protocol fidelity must be preserved across extended operation cycles.

Key Features

• Gentle 2D rocking motion with fixed 8° inclination ensures high repeatability and eliminates positional bias during incubation or hybridization steps.
• Microprocessor-based speed control provides stable, drift-free operation from 5 to 80 rpm in 1-rpm increments, displayed via clear 7-segment LED readout.
• Rated for continuous 100% duty cycle operation—suitable for unattended overnight protocols inside refrigerated or ambient-temperature incubators (4–50 °C).
• Compact footprint (280 × 150 × 330 mm) and stackable design (30 mm vertical increment per unit) optimize bench space in high-density lab environments.
• Included non-slip rubber mat prevents lateral displacement during operation; aluminum alloy platform offers corrosion resistance and thermal stability.
• Complies with DIN EN 60529 (IP21) for protection against vertically falling droplets and solid objects >12.5 mm—appropriate for standard laboratory settings but not wet or splash-prone areas.
• No external communication interfaces (USB, RS232, analog output) are integrated, aligning with ISO/IEC 17025 requirements for simplified validation and reduced cybersecurity surface in regulated QC labs.

Sample Compatibility & Compliance

The ROCKER 2D basic accommodates standard laboratory vessels—including Petri dishes, multi-well plates (6–96-well), staining trays, blotting cassettes, and conical tubes—via optional IKA-compatible clamps (e.g., plate holders, universal racks, gel trays). Its 2 kg maximum payload (including clamp mass) supports simultaneous processing of multiple samples without mechanical resonance or amplitude decay. The device meets CE marking requirements under the EU Machinery Directive 2006/42/EC and Low Voltage Directive 2014/35/EU. While not designed for sterile environments or pressurized enclosures, its operational envelope (4–50 °C, ≤80% RH) permits integration into validated incubator systems used in molecular biology, histology, and diagnostic assay development per CLIA and ISO 15189 frameworks.

Software & Data Management

As a stand-alone analog-controlled instrument, the ROCKER 2D basic does not incorporate embedded software, network connectivity, or electronic data logging. This architecture eliminates firmware dependencies, reduces qualification burden (IQ/OQ/PQ), and simplifies compliance with FDA 21 CFR Part 11 when used in conjunction with paper-based or LIMS-managed SOPs. Speed settings are manually configured and retained only during active power supply—no memory retention or audit trail functionality is provided, consistent with its classification as a Class I general-purpose laboratory accessory under IEC 61010-1 safety standards.

Applications

• Western/Northern/Southern blotting: Uniform antibody and probe incubation with minimal membrane distortion.
• Cell dissociation and suspension: Gentle resuspension of adherent or semi-adherent cultures prior to passaging.
• ELISA and immunoassay plate washing: Controlled agitation during buffer exchange steps to reduce background noise.
• Gel staining and destaining: Efficient diffusion-based dye penetration without gel fragmentation.
• Low-speed hybridization: Stable rocking during DNA/RNA probe binding at elevated temperatures (up to 50 °C).
• Reagent equilibration: Homogenization of viscous buffers, enzyme solutions, or agarose preps prior to dispensing.

FAQ

Is the ROCKER 2D basic suitable for use inside a CO₂ incubator?
Yes—its rated operating temperature range (4–50 °C) and IP21 ingress protection allow safe placement in non-humidified CO₂ incubators. However, condensation-prone environments require external enclosure or periodic inspection per ISO 13485 environmental monitoring guidelines.
Can multiple units be synchronized for parallel processing?
No synchronization capability is provided; each unit operates independently. For time-critical multi-step assays, manual start alignment is recommended.
Does the device support programmable timing or automatic shut-off?
No timer or auto-stop function is included. Continuous operation is intended for applications requiring uninterrupted motion over indefinite periods.
What maintenance is required for long-term reliability?
Annual visual inspection of rocker arm pivot points and motor housing integrity is advised. No lubrication or calibration is specified by IKA—performance verification is limited to speed accuracy checks using an external tachometer per ASTM E2916.
Are third-party clamps compatible with this model?
Only IKA-certified accessories (e.g., RK-100, RK-200 series) guarantee mechanical fit, load distribution, and torque compatibility. Non-OEM fixtures may compromise stability or void warranty coverage under IKA’s 2-year limited warranty.
