IKA ROLLER 6 basic 6-Axis Rolling Mixer

Overview

The IKA ROLLER 6 basic is a compact, fixed-speed 6-axis rolling mixer engineered for gentle, continuous homogenization of sensitive biological and viscous samples in laboratory and bioprocessing environments. Unlike orbital shakers or vortex mixers, this device employs a dual-mode motion profile—combining controlled rocking and axial rotation—to induce low-shear laminar flow across multiple sample vessels simultaneously. Its core principle relies on precise mechanical translation of rotational energy into consistent, non-turbulent displacement, minimizing foaming, phase separation, or cellular damage during prolonged incubation-compatible mixing. Designed for integration into refrigerated incubators, cold rooms, or ambient lab benches, the unit operates continuously at a calibrated 30 rpm with a fixed 3° tilt angle and 16 mm end-to-end roller travel—ensuring reproducible agitation kinetics without speed variability or timing dependencies.

Key Features

• Six independently mounted, removable 32 mm-diameter rollers with standardized 327 mm length—compatible with common cylindrical containers including 13–18 mm diameter test tubes, centrifuge tubes, and culture bottles.
• Fixed 30 rpm operation ensures stable, vibration-free performance ideal for long-term assays requiring uninterrupted mixing over hours or days.
• IP21-rated enclosure provides protection against vertically falling drips and solid objects >12.5 mm—suitable for use in standard biosafety cabinets, incubators, and shared core facilities.
• Modular platform design supports vertical stacking with identical units to maximize throughput within constrained bench space.
• Ergonomic roller mounting system enables rapid disassembly for cleaning or replacement—critical for maintaining sterility in GLP-compliant workflows involving blood, serum, or cell suspensions.
• Universal power input (100–240 V AC, 50/60 Hz) and internal 24 V DC conversion ensure stable operation across global laboratory electrical infrastructures.

Sample Compatibility & Compliance

The ROLLER 6 basic accommodates a broad range of container geometries without adapters—including conical-bottom tubes, flat-bottom vials, and narrow-necked glass or polymer bottles up to 100 mL volume. Its low-amplitude, high-consistency motion preserves integrity of fragile biological matrices such as whole blood, PBMC suspensions, antibody-conjugated beads, and high-viscosity reagents (e.g., glycerol-based storage buffers). The device meets DIN EN 60529 (IP21), conforms to IEC 61010-1 safety standards for laboratory equipment, and supports compliance with ISO/IEC 17025 requirements when integrated into documented sample preparation SOPs. While not intrinsically certified for GMP or FDA 21 CFR Part 11 environments, its deterministic operation, absence of programmable logic, and mechanical simplicity facilitate straightforward validation for routine QC/QA applications in clinical diagnostics and biomanufacturing support labs.

Software & Data Management

The ROLLER 6 basic operates as a standalone analog instrument with no embedded microprocessor, firmware, or digital interface. It features tactile membrane keys for power activation only—eliminating software dependencies, cybersecurity risks, or data logging requirements. This architecture ensures operational reliability across extended periods without calibration drift or firmware updates. For laboratories implementing electronic lab notebooks (ELNs) or LIMS integration, manual recording of operational parameters (e.g., start time, ambient temperature, vessel type) is recommended as part of traceable sample handling procedures. No audit trail, user access control, or electronic signature capability is provided—consistent with its role as a foundational, non-critical mixing tool in tiered instrumentation hierarchies.

Applications

• Continuous mixing of anticoagulated whole blood prior to centrifugation in clinical hematology workflows.
• Re-suspension of lyophilized proteins, enzymes, or diagnostic reagents in viscous excipients.
• Homogenization of immunoassay plates during wash steps where orbital shaking induces edge effects or splashing.
• Incubator-integrated agitation of bacterial or yeast cultures in sealed tubes under controlled temperature (4–50 °C).
• Pre-analytical processing of environmental water samples containing particulate matter or biofilm fragments.
• Supporting ASTM D7575 and ISO 11733 protocols requiring gentle agitation of suspended solids prior to filtration or analysis.

FAQ

Does the ROLLER 6 basic support variable speed or timer functions?
No. It operates exclusively at a fixed 30 rpm with no speed adjustment or timing circuitry.
Can it be used inside a CO₂ incubator?
Yes—provided the incubator maintains ambient humidity below 80 % RH and allows adequate ventilation around the unit’s rear heat dissipation zone.
Is the roller assembly autoclavable?
Rollers are mechanically detachable but not autoclavable; they are cleaned with 70 % ethanol or isopropanol and air-dried per IKA’s maintenance guidelines.
What is the maximum load capacity per roller?
Each roller supports up to 500 g total mass (vessel + contents); exceeding this may affect tilt angle consistency and long-term bearing wear.
How is temperature stability maintained during operation?
The unit itself does not regulate temperature—it is designed for passive thermal compatibility within externally controlled environments (e.g., refrigerated incubators or cold rooms).
Are replacement rollers available as spare parts?
Yes—original IKA roller assemblies (Order No. 0000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000……
