IKA ROLLER 10 digital Roll Mixer

Overview

The IKA ROLLER 10 digital is a precision-engineered roll mixer designed for gentle, reproducible mixing of biological and biochemical samples under controlled conditions. Unlike orbital or reciprocating shakers, this instrument employs a dual-mode motion profile—simultaneous rocking and rolling—optimized to minimize shear stress while maximizing homogeneity in viscous, particulate-laden, or sediment-prone suspensions. Its 10 independently mounted rollers rotate with a fixed 3° tilt angle and ±16 mm end-to-end travel, generating consistent tumbling action ideal for blood collection tubes, centrifuge tubes, culture bottles, and cylindrical vials up to 50 mL capacity. The device operates without internal heating or cooling elements; instead, it is explicitly engineered for stable, continuous operation inside incubators, cold rooms, or environmental chambers maintained between 4 °C and 50 °C—making it suitable for applications requiring temperature-controlled agitation during long-term incubation protocols.

Key Features

• Gentle dual-motion agitation: synchronized rocking and rolling ensures uniform suspension without foaming or cell lysis.
• Digitally controlled speed range from 5 rpm (minimum adjustable) to 80 rpm in 1-rpm increments, displayed via 7-segment LED.
• Precise timer functionality with programmable duration from 1 second to 5999 seconds (up to 1 h 40 min), supporting both timed and continuous operation modes.
• Modular roller design: all 10 rollers (Ø32 mm × 327 mm) are fully detachable and interchangeable—enabling rapid cleaning after sample spillage or cross-contamination events.
• Robust aluminum housing with IP21 ingress protection, rated for ambient operation at 4–50 °C and ≤80% relative humidity.
• Compact footprint (380 × 115 × 545 mm) and stackable work surface facilitate integration into multi-tier incubator setups or biosafety cabinets.
• Energy-efficient operation: 24 W nominal power draw with universal 100–240 V AC input, eliminating need for voltage converters in global labs.

Sample Compatibility & Compliance

The ROLLER 10 digital accommodates standard tube formats including 12–16 mm diameter round-bottom and conical tubes (e.g., Vacutainer®, Eppendorf®, Falcon®), as well as cylindrical glass or plastic bottles up to 50 mL volume. Its low-shear motion profile meets requirements for handling fragile biological matrices such as whole blood, PBMC suspensions, agarose gels, antibody-conjugated beads, and high-viscosity reagents. While the unit itself does not incorporate active thermal regulation, its mechanical design conforms to DIN EN 60529 (IP21) for protection against vertically falling drips and solid objects >12.5 mm—ensuring safe use in GLP-compliant environments where equipment qualification includes physical robustness and operational stability. No RS232, USB, or analog output interfaces are provided; thus, it is classified as a standalone, non-networked laboratory device compliant with basic IEC 61010-1 safety standards for electrical equipment used in laboratory settings.

Software & Data Management

The ROLLER 10 digital operates exclusively via front-panel touch controls and embedded firmware—no external software, drivers, or connectivity options are required or supported. All operational parameters—including real-time elapsed time, set speed, and remaining timer duration—are displayed on dual 7-segment LED indicators. Error codes (e.g., E1 for motor overload, E2 for sensor fault) appear automatically upon system anomaly detection, facilitating immediate troubleshooting without diagnostic tools. As a Class I, non-data-logging instrument, it does not generate electronic records, nor does it support FDA 21 CFR Part 11 compliance features such as user authentication, audit trails, or electronic signatures. Its simplicity aligns with laboratories prioritizing ease-of-use, minimal validation burden, and maintenance-free deployment in QC/QA workflows where traceability is managed manually or via external LIMS integration.

Applications

• Anticoagulated blood sample mixing prior to hematocrit, coagulation panel, or flow cytometry analysis.
• Re-suspension of lyophilized reagents, bacterial pellets, or magnetic bead-based immunoassays.
• Homogenization of viscous solutions including glycerol stocks, protein gels, and polymerase chain reaction (PCR) master mixes.
• Long-duration incubation mixing of enzyme-substrate reactions, ELISA plate coating steps, and antigen-antibody binding assays.
• Pre-analytical sample conditioning in clinical diagnostics laboratories operating under ISO 15189-accredited quality management systems.

FAQ

Can the ROLLER 10 digital be operated inside a CO₂ incubator?

Yes—its passive thermal design and IP21-rated enclosure allow safe, uninterrupted operation within humidified CO₂ incubators maintained between 4 °C and 50 °C, provided airflow is unobstructed and condensation is minimized.
Is the roller tilt angle adjustable?

No—the 3° fixed tilt angle is factory-set to optimize tumbling efficiency across common tube geometries and cannot be modified by the user.
Does the unit support external triggering or remote start/stop?

No—operation is limited to manual initiation via tactile keypad; no digital interface or trigger inputs are available.
What is the maximum recommended load per roller?

Each roller supports up to 500 g total load (including tube + contents); exceeding this may affect speed stability and long-term bearing life.
Are replacement rollers available as spare parts?

Yes—IKA supplies OEM roller assemblies (part number 0002000222) compatible with ROLLER 10 digital, enabling full refurbishment without recalibration.
