IKA ROLLER 10 digital 10-Axis Digital Rocker Mixer

Overview

The IKA ROLLER 10 digital is a precision-engineered 10-axis digital rocker mixer designed for gentle, consistent, and reproducible mixing of biological and biochemical samples in laboratory environments. Unlike orbital shakers or vortex mixers, this instrument employs a controlled rocking motion—defined by a fixed 3° tilt angle and bidirectional oscillation—optimized to minimize shear stress while maximizing homogenization efficiency. Its mechanism follows the principle of unidirectional rocking with programmable reversal, enabling uniform suspension of cells, precipitates, immunoassay reagents, and viscous matrices without foaming or phase separation. The device is engineered for continuous operation under ambient or incubator conditions (4–50 °C), making it suitable for integration into cell culture workflows, ELISA plate preparation, blood sample stabilization, and long-term hybridization protocols. Its robust aluminum housing, IP21-rated enclosure, and low-power 24 W DC drive system ensure operational reliability and energy efficiency across diverse life science settings.

Key Features

• 10 independently aligned rocking axes with removable, autoclavable rollers (Ø32 mm × 327 mm) for parallel processing of up to ten standard tubes or cylindrical vessels
• Digital speed control from 0–80 rpm in 1-rpm increments, with a minimum adjustable speed of 5 rpm for ultra-gentle agitation
• Precise LED-displayed timing function supporting both countdown (1 s – 99 h 59 min) and elapsed-time tracking, compliant with GLP documentation requirements
• Touch-sensitive membrane keypad with intuitive navigation and real-time feedback—no mechanical switches to degrade over time
• Fixed 3° rocking angle ensures optimal liquid displacement and meniscus movement without splashing; end-travel limit of ±16 mm per axis guarantees mechanical repeatability
• Compact footprint (380 × 115 × 545 mm) and lightweight design (6 kg) facilitate placement inside incubators, cold rooms, or biosafety cabinets
• Universal power input (100–240 V AC, 50/60 Hz) with internal 24 V DC conversion—eliminates need for external transformers and supports global deployment

Sample Compatibility & Compliance

The ROLLER 10 digital accommodates common laboratory containers including 12–18 mm diameter test tubes, microcentrifuge tubes (with optional adapters), serum bottles (up to 50 mL), and glass or plastic cylindrical vials. Its low-shear rocking profile preserves cellular integrity in whole-blood anticoagulant mixing, bacterial culture resuspension, and antibody-antigen binding assays. The unit complies with DIN EN 60529 (IP21) for protection against vertically falling drops and solid objects >12.5 mm, meeting basic environmental safety standards for non-hazardous lab zones. While not certified for cleanroom Class ISO 5 or higher, its sealed electronics and tool-free roller removal support routine decontamination using 70% ethanol or hospital-grade disinfectants. No integrated temperature control is provided; however, full compatibility with externally regulated incubators (4–50 °C) enables use in validated workflows requiring thermal stability per ISO/IEC 17025 or CLIA guidelines.

Software & Data Management

The ROLLER 10 digital operates as a standalone hardware platform with no embedded software stack or PC connectivity. All operational parameters—including speed, timer duration, and run status—are managed locally via the front-panel interface. Timer events are logged internally with error-code display (e.g., E1 = motor overload, E2 = sensor fault), aiding rapid troubleshooting during routine QC checks. Though lacking USB or Ethernet ports, its deterministic timing architecture ensures traceability: each session’s start time, duration, and final rpm value remain visible on the LED display until manually reset. This design aligns with FDA 21 CFR Part 11 principles for instruments where electronic records are not generated—eliminating audit-trail complexity while maintaining procedural consistency across shifts and operators.

Applications

• Stabilization of EDTA- or citrate-anticoagulated whole blood prior to centrifugation (ASTM D6134-20)
• Resuspension of lyophilized reagents, bacterial pellets, and cryopreserved cell stocks
• Hybridization steps in Southern/Northern blotting and DNA probe incubations
• Coating uniformity verification in ELISA plate pre-wash stages
• Viscous sample homogenization—including glycerol-based buffers, agarose gels, and protein A/G suspensions
• Long-duration mixing of immunoaffinity capture assays requiring >24 h incubation

FAQ

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

Yes—it is rated for continuous operation at ambient temperatures from 4 °C to 50 °C and relative humidity up to 80 %, making it compatible with standard humidified CO₂ incubators when placed on stable, vibration-dampened surfaces.
Are replacement rollers available, and are they autoclavable?

Yes—rollers are designed for quick release and can be sterilized via autoclaving (121 °C, 20 min, gravity cycle) or chemical immersion. IKA part number RW10.001 covers the standard roller set.
Does the device support external triggering or data logging?

No—the ROLLER 10 digital has no communication interfaces (RS-232, USB, or analog outputs) and does not support remote start/stop or automated data export.
What is the maximum recommended tube diameter for secure clamping?

Tubes up to 18 mm outer diameter are reliably retained using the standard roller groove geometry; larger diameters require custom adapter sleeves (not included).
Is the 3° rocking angle adjustable?

No—the tilt angle is mechanically fixed at 3° to ensure repeatable fluid dynamics and prevent slippage during extended runs; this configuration is optimized for laminar displacement rather than turbulent mixing.
