IKA ULTRA-TURRAX® Tube Drive Dispersion System

Overview

The IKA ULTRA-TURRAX® Tube Drive is a compact, benchtop dispersion system engineered for safe, reproducible, and contamination-free sample homogenization in biosafety-sensitive and regulated laboratory environments. Unlike conventional open-vessel dispersers, this system operates exclusively within sealed, single-use polypropylene tubes—eliminating aerosol generation, operator exposure, and carryover between samples. Its core principle relies on high-shear mechanical dispersion via a rotating magnetic drive that couples with an internal rotor inside the closed tube. This contactless torque transmission enables efficient energy transfer while maintaining full containment. Designed for applications requiring strict adherence to biosafety level 2 (BSL-2) practices, GLP-compliant workflows, or ISO 17025-accredited testing protocols, the Tube Drive supports consistent particle size reduction, cell lysis, emulsification, and suspension stabilization—all without manual handling of hazardous or odorous materials.

Key Features

• Sealed-tube processing architecture prevents aerosol release, cross-contamination, and operator exposure to infectious agents, cytotoxic compounds, or volatile analytes.
• Integrated 24 V DC drive system ensures intrinsic electrical safety—compliant with IEC 61000-6-3 for electromagnetic compatibility and rated IP20 per DIN EN 60529.
• Two standardized tube formats: 2–15 mL and 15–50 mL gamma-sterilized polypropylene tubes, available with or without gas-permeable membrane caps for aerobic culture-compatible homogenization.
• Stepless speed control from 300 to 6000 rpm enables precise adaptation to sample rheology—validated up to 5000 mPa·s viscosity under batch conditions.
• Acoustic end-of-process signal and calibrated rotational scale support unattended operation and inter-operator reproducibility across QC, clinical diagnostics, and preclinical research settings.
• No cleaning or maintenance required between runs—tubes are disposed of post-use, eliminating validation burdens associated with shared hardware in GMP/GLP environments.

Sample Compatibility & Compliance

The ULTRA-TURRAX® Tube Drive accommodates a broad range of biological, pharmaceutical, and industrial samples—including mammalian tissues, bacterial pellets, plant extracts, nanoparticle suspensions, and viscous polymer solutions—within its defined volume and viscosity limits. All tubes comply with USP for plastic packaging materials and are certified non-pyrogenic following gamma irradiation (25 kGy). The system meets essential requirements of ISO 13485 for medical device manufacturing support processes and aligns with FDA 21 CFR Part 11 data integrity expectations when paired with compliant LIMS or ELN platforms (via external timer/logging integration). Its low-noise operation (<50 dB(A)) permits deployment in shared lab spaces without acoustic interference.

Software & Data Management

While the Tube Drive operates as a stand-alone analog instrument without embedded microprocessor control, its design facilitates traceability in regulated environments. Users may integrate external programmable timers or PLC-based controllers to log start/stop timestamps, speed setpoints, and run duration—supporting audit-ready records per ALCOA+ principles. IKA provides calibration certificates for speed accuracy (±10% deviation at full scale) and mechanical stability testing reports upon request. For laboratories implementing electronic quality management systems (eQMS), the system’s deterministic mechanical behavior and absence of firmware reduce validation scope compared to digitally controlled homogenizers.

Applications

• Routine nucleic acid and protein extraction workflows where RNase/DNase-free conditions and sample integrity are critical.
• Pre-analytical sample preparation for LC-MS, ICP-MS, and ELISA assays—ensuring uniform matrix dispersion without metal leaching or surfactant carryover.
• Homogenization of BSL-2 pathogens (e.g., SARS-CoV-2 swab specimens, influenza A cultures) under containment protocols aligned with WHO Laboratory Biosafety Manual (4th ed.).
• Formulation development of nanoemulsions and colloidal drug carriers, where narrow polydispersity index (PDI) depends on consistent shear history.
• QC testing of excipient blends and active pharmaceutical ingredient (API) suspensions in accordance with USP and Ph. Eur. 2.9.31.

FAQ

Can the ULTRA-TURRAX® Tube Drive be used for cryogenic homogenization?

No—operating temperature must remain within 5–40 °C; tubes are not rated for sub-zero mechanical stress or thermal shock.
Is speed calibration traceable to national standards?

Yes—optional NIST-traceable calibration certificates are available for rotational speed verification at three points across the 300–6000 rpm range.
Does IKA provide validation documentation for GMP environments?

IKA supplies IQ/OQ templates, risk assessments (per ISO 14971), and material compliance dossiers (including RoHS and REACH declarations) to support equipment qualification.
What is the expected service life of the drive unit under continuous use?

Rated for ≥10,000 operating hours with periodic inspection of magnetic coupling alignment and housing integrity per IKA Technical Bulletin UT-TD-MAINT-2023.
Are third-party tubes compatible with this system?

Only IKA-certified tubes guarantee dimensional tolerances, magnetic rotor balance, and burst pressure resistance; use of non-OEM tubes voids warranty and compromises safety certification.
