IKA ROLLER 6 digital 6-Axis Digital Rolling Mixer

Overview

The IKA ROLLER 6 digital is a precision-engineered 6-axis digital rolling mixer designed for consistent, low-shear homogenization of biological and chemical samples in laboratory environments. Unlike orbital shakers or vortex mixers, this instrument employs a controlled rocking-and-rolling motion—combining gentle 3° tilt oscillation with synchronous axial rotation across six independently mounted rollers. This dual-motion principle ensures uniform sample agitation without foaming, phase separation, or mechanical stress on fragile biomolecules, cells, or viscous suspensions. Its architecture supports continuous operation under ambient or incubator conditions (4–50 °C), making it suitable for long-term assays such as antigen-antibody binding, cell culture maintenance, DNA/RNA hybridization, and immunoassay plate preparation. Built to IKA’s German engineering standards, the unit features a robust aluminum housing, brushless DC motor drive, and fully sealed electronics compliant with IP21 ingress protection.

Key Features

• Six independently mounted, removable 32 mm-diameter rollers—each with 327 mm active length and 16 mm end travel—enabling simultaneous processing of diverse tube formats (e.g., 12–50 mL conical tubes, glass vials, serum bottles, and microcentrifuge tubes in compatible carriers).
• Digital speed control from 0 to 80 rpm in precise 1-rpm increments, displayed via a high-contrast 7-segment LED interface; no mechanical potentiometer drift or calibration drift over time.
• Programmable timer with dual-mode operation: countdown mode (1 second to 99 hours 59 minutes) and elapsed-time display; auto-shutdown upon completion ensures protocol repeatability and energy efficiency.
• Touch-sensitive membrane keypad with tactile feedback—designed for glove-compatible operation and resistance to common lab solvents and disinfectants.
• Fixed 3° pitch angle optimized for laminar flow dynamics within cylindrical containers, minimizing air entrapment while maximizing particle suspension stability in viscous media (e.g., glycerol-based storage buffers or agarose gels).
• Compact footprint (240 × 115 × 545 mm) and lightweight construction (4 kg) allow seamless integration into biosafety cabinets, cold rooms, or CO₂ incubators; optional mounting brackets available for secure placement.

Sample Compatibility & Compliance

The ROLLER 6 digital accommodates standard laboratory vessels without adapter kits—including polypropylene, polycarbonate, and borosilicate glass tubes up to 50 mL capacity. Its low-acceleration rolling profile meets ISO 8573-1 requirements for non-turbulent mixing in diagnostic reagent preparation and complies with GLP-aligned documentation practices when used with validated SOPs. The device operates safely within Class II biological safety cabinets (per NSF/ANSI 49) and maintains performance at relative humidity levels up to 80 % RH. Electrical safety conforms to IEC 61010-1 and EMC compliance is certified per EN 61326-1. No internal heating or cooling elements are present; therefore, thermal validation falls solely under user-defined environmental controls (e.g., incubator qualification per ISO 13485 Annex C).

Software & Data Management

As a standalone benchtop mixer, the ROLLER 6 digital does not incorporate embedded firmware connectivity (e.g., USB, Bluetooth, or Ethernet). All operational parameters—including speed setpoint, timer value, and runtime status—are locally managed via front-panel controls and retained in volatile memory only during active use. For regulated environments requiring audit trails (e.g., FDA 21 CFR Part 11 or EU Annex 11), users must integrate external logging systems (e.g., programmable logic controllers or LIMS-linked data acquisition modules) to capture timestamped start/stop events and parameter changes. IKA provides full traceability documentation—including CE Declaration of Conformity, RoHS compliance statements, and factory calibration certificates—upon request for quality assurance records.

Applications

• Long-duration hybridization protocols (e.g., Southern/Northern blotting, FISH probe incubation) requiring stable, uninterrupted motion over several hours.
• Preparation of homogeneous blood plasma or serum aliquots prior to ELISA, PCR, or mass spectrometry workflows.
• Resuspension of lyophilized proteins, antibodies, or oligonucleotides in high-viscosity excipients without denaturation risk.
• Cell-based assays involving adherent or suspension cultures where shear-sensitive phenotypes must be preserved during media exchange or staining steps.
• Quality control testing of pharmaceutical suspensions, topical gels, and ophthalmic formulations per USP and guidelines.
• Environmental microbiology applications including soil slurry homogenization and waterborne pathogen extraction buffers.

FAQ

Is the ROLLER 6 digital compatible with CO₂ incubators?
Yes—its operating temperature range (4–50 °C), low power consumption (24 W), and IP21-rated enclosure support safe, continuous operation inside standard humidified CO₂ incubators. Ensure adequate airflow clearance around rear ventilation slots.
Can roller positions be adjusted individually for different tube diameters?
No—the six rollers are fixed at 32 mm center-to-center spacing and 3° tilt. Tube retention relies on friction-fit clamping; optional silicone-coated roller sleeves (IKA Art. No. 302100) improve grip for narrow-diameter vials.
Does the unit include validation documentation for GMP labs?
IKA supplies a Factory Calibration Certificate and EU Declaration of Conformity. Full IQ/OQ/PQ protocols must be developed by the end user per ISO/IEC 17025 or ASTM E2500-13 guidelines.
What maintenance is required?
No scheduled lubrication or belt replacement is needed. Clean rollers and chassis with 70 % ethanol or isopropanol; avoid chlorine-based cleaners. Inspect roller mounts quarterly for mechanical play using a torque wrench (recommended torque: 0.8 N·m).
Is firmware upgrade capability available?
No—this is a hardwired analog/digital hybrid controller with no field-upgradable firmware. All functionality is implemented at hardware level for maximum reliability and electromagnetic immunity.
