IKA ROCKER 2D digital Rocking Mixer

Overview

The IKA ROCKER 2D digital is a precision-engineered rocking mixer designed for consistent, gentle sample homogenization in life science and biotechnology laboratories. Unlike orbital or vortex shakers, this instrument employs a controlled two-dimensional rocking motion—oscillating around a central horizontal axis with adjustable angular amplitude—to ensure uniform suspension of cells, reagents, gels, and immunoassay plates without shear-induced damage. Its microprocessor-controlled DC motor maintains constant speed across varying loads and input voltage fluctuations, delivering high reproducibility essential for ELISA plate washing, blotting membrane incubation, hybridization protocols, and low-shear cell resuspension. The device operates silently and efficiently within standard incubators (4–50 °C), making it suitable for integration into temperature-controlled workflows without thermal interference.

Key Features

• Digitally adjustable rocking angle (2.5° to 15°) enables optimization for diverse vessel geometries—from shallow Petri dishes to tall culture flasks—ensuring laminar fluid displacement rather than turbulent mixing.
• Precise speed control from 0 to 80 rpm in 1-rpm increments, displayed on a dual seven-segment LED screen for real-time monitoring and traceable parameter setting.
• Programmable timer with resolution down to 1 second and maximum duration of 99 hours 59 minutes; supports both countdown operation and elapsed time display with automatic shutdown or continuous mode selection.
• Robust aluminum housing and anti-slip rubber feet ensure stability during extended unattended runs; compatible with stacking of multiple units vertically (30 mm inter-unit clearance required).
• IP21-rated enclosure provides protection against vertically falling drips and solid objects >12.5 mm—validated for safe use in general laboratory environments and incubator chambers.
• Energy-efficient 24 W power draw and universal 100–240 V AC input enable global deployment without voltage converters; internal 24 V DC supply ensures electromagnetic compatibility and reduced heat generation.

Sample Compatibility & Compliance

The ROCKER 2D digital accommodates standard labware including glass and plastic test tubes (up to 50 mL), conical centrifuge tubes, multi-well plates (6–96-well), Petri dishes, Erlenmeyer flasks (up to 250 mL), and staining trays. Optional clamping accessories—including universal plate holders, flask adapters, and custom silicone mats—extend compatibility to irregular or oversized vessels. The system complies with EU Machinery Directive 2006/42/EC, Low Voltage Directive 2014/35/EU, and EMC Directive 2014/30/EU. While not inherently GLP/GMP-certified, its stable performance, error-code diagnostics (e.g., overload, motor stall), and non-volatile timer settings support audit-ready documentation when integrated into validated SOPs per ISO/IEC 17025 or FDA 21 CFR Part 11–aligned workflows.

Software & Data Management

This stand-alone instrument does not require external software or drivers. All operational parameters are set and monitored via intuitive capacitive touch keys with tactile feedback. The LED display logs elapsed time, remaining time, current speed, and active rocking angle. Error codes (e.g., “E1” for motor blockage, “E2” for overtemperature) appear automatically during fault conditions, aiding rapid troubleshooting without service intervention. For laboratories requiring electronic records, the device’s deterministic behavior—repeatable speed/angle/timing profiles—allows full integration into LIMS or ELN platforms via manual entry or barcode-scanned protocol templates. No proprietary firmware updates are required; hardware calibration is factory-set and drift-free over typical service intervals.

Applications

• Western blot and immunostaining: uniform antibody incubation and wash steps on PVDF or nitrocellulose membranes.
• Molecular biology: gentle DNA/RNA hybridization in Southern/Northern blots; restriction enzyme digestions requiring minimal agitation.
• Cell culture: resuspension of adherent or suspension cells prior to passaging or viability assays.
• Clinical diagnostics: ELISA plate incubation and substrate development under standardized rocking conditions.
• Gel electrophoresis: post-run staining and destaining of agarose or polyacrylamide gels.
• Environmental microbiology: mixing of water samples with enrichment media prior to filtration or plating.

FAQ

Can the ROCKER 2D digital be used inside a CO₂ incubator?
Yes—its operating temperature range (4–50 °C) and IP21 rating permit safe placement in humidified CO₂ incubators, provided ambient condensation is minimized and airflow around vents remains unobstructed.

Is speed accuracy traceable to national standards?
Speed calibration is performed at the factory using NIST-traceable tachometric reference equipment; a certificate of conformance is supplied with each unit.

What maintenance is required for long-term reliability?
No routine lubrication or mechanical adjustment is needed. Wipe exterior surfaces with 70% ethanol; inspect rubber feet periodically for compression set. Motor lifetime exceeds 20,000 hours under continuous operation.

Are third-party clamps supported?
Only IKA-certified accessories (e.g., part nos. 0002700000, 0002700100) are validated for load distribution and vibration damping; non-OEM clamps may compromise stability or void warranty.

Does the timer retain settings after power loss?
No—the device lacks non-volatile memory for timer presets; however, all active parameters (speed, angle, mode) persist during brief interruptions (<100 ms); full reset occurs only upon complete power-down.
