IKA UTTD Tube Dispersion System

Overview

The IKA UTTD Tube Dispersion System is a compact, CE-compliant benchtop device engineered for safe, efficient, and contamination-free homogenization of small-volume biological and chemical samples in sealed tubes. Unlike conventional vortex mixers or rotor-stator homogenizers, the UTTD employs a high-torque, low-voltage (24 V DC) electromagnetic drive mechanism that transmits mechanical energy through the tube wall—eliminating direct contact between the drive unit and sample container. This non-invasive coupling enables true closed-tube processing, making it especially suitable for biosafety level 2 (BSL-2) applications involving infectious agents, cytotoxic compounds, volatile solvents, or odoriferous analytes. The system operates on the principle of orbital oscillation combined with controlled axial vibration, delivering reproducible shear forces across heterogeneous suspensions without introducing air bubbles or thermal artifacts typical of high-speed rotor systems. Its design complies with DIN EN 60529 (IP20), IEC 61000-6-3 (EMC), and IEC 61000-6-2 (immunity), ensuring stable performance in regulated laboratory environments.

Key Features

• 24 V DC isolated drive architecture—meets SELV (Safety Extra-Low Voltage) requirements per IEC 61010-1, minimizing electrical hazard risk in wet or conductive lab settings
• Patented magnetic coupling interface compatible exclusively with IKA-certified, γ-irradiated single-use tubes (including 50 mL format with perforated membrane cap for gas exchange during processing)
• Three-in-one functional capability: dispersion, homogenization, and fine grinding—achieved via interchangeable tube holders and optimized oscillation profiles
• Integrated anti-lock safety latch prevents accidental opening during operation; mechanical interlock disengages power upon lid release
• Chemically resistant housing (PP, POM, and stainless-steel fasteners) withstands repeated exposure to ethanol, isopropanol, dilute acids/bases, and common disinfectants
• Graduated analog speed dial enables precise manual setting within 300–6000 rpm range; ±10% speed tolerance maintained across full load spectrum
• Low acoustic signature (≤50 dB(A) at 1 m, no dispersing element installed) supports use in shared core facilities and quiet analytical labs

Sample Compatibility & Compliance

The UTTD is validated for use with IKA’s proprietary line of gamma-sterilized, RNase/DNase-free polypropylene tubes—available in 1.5 mL, 5 mL, and 50 mL volumes. The 50 mL variant features a hydrophobic microporous membrane cap (0.2 µm pore size), permitting CO₂/O₂ exchange while retaining aerosols and particulates. All tube configurations maintain integrity under peak operational torque (up to 0.15 N·m) and temperature excursions ≤40 °C. The system conforms to ISO 13485:2016 (medical device quality management), supports GLP documentation workflows, and facilitates audit readiness for FDA 21 CFR Part 11 compliance when integrated with traceable electronic lab notebooks (ELNs). It is routinely deployed in diagnostic laboratories accredited to ISO/IEC 17025 and clinical research units adhering to CLIA and CAP standards.

Software & Data Management

The UTTD operates as a standalone instrument without embedded firmware or digital connectivity—intentionally designed to minimize validation burden in GxP environments. All operational parameters are manually set and visually verified via the calibrated speed scale; no software-defined protocols or electronic logs are generated. This architecture eliminates cybersecurity risks, reduces qualification scope (IQ/OQ/PQ), and aligns with ALCOA+ data integrity principles by ensuring raw output remains directly attributable to human operator input. For laboratories requiring traceability, optional external time-lapse video recording or mechanical timer integration is supported—fully compliant with Annex 11 and MHRA GxP Data Integrity Guidance.

Applications

• Homogenization of tissue biopsies, cell pellets, and microbial cultures prior to nucleic acid extraction or protein solubilization
• Dispersion of nanoparticle suspensions (e.g., liposomes, polymeric micelles) in pharmaceutical formulation development
• Emulsification of cosmetic actives in aqueous-organic matrices without surfactant degradation
• Pre-analytical sample conditioning for ELISA, PCR, and flow cytometry workflows in clinical diagnostics
• Disaggregation of fibrous plant material or fungal mycelia for metabolomic profiling
• Routine mixing of viscous reagents (up to 5000 mPa·s) in QC/QA testing for food safety and environmental monitoring

FAQ

Is the UTTD suitable for use with hazardous pathogens?
Yes—the closed-tube operation, BSL-2-compatible design, and disposable tube system prevent aerosol generation and cross-contamination. It is widely adopted in virology and immunology labs handling SARS-CoV-2, influenza, and HIV pseudoviruses.
Can the UTTD be integrated into automated liquid handling platforms?
No—it is a manually operated, non-networked device. However, its footprint (100 × 40 × 160 mm) allows placement within Class II biosafety cabinets or robotic workcells for semi-automated batch loading.
What maintenance is required?
None beyond periodic wipe-down with 70% ethanol. There are no consumable parts other than the single-use tubes; the electromagnetic drive has no brushes or bearings subject to wear.
Does IKA provide calibration certificates?
Yes—traceable speed verification reports (NIST-traceable tachometer calibration) are available upon request for regulatory submissions and internal SOP alignment.
Is the 24 V DC supply included?
Yes—the system ships with an IKA-certified switching power adapter (input: 100–240 V AC; output: 24 V DC / 1.2 A), fully compliant with IEC 62368-1 and RoHS 3 directives.
