IKA T25 Digital ULTRA-TURRAX® High-Performance Disperser

Overview

The IKA T25 Digital ULTRA-TURRAX® is a high-torque, digitally controlled high-shear disperser engineered for precision homogenization, emulsification, and cell disruption in laboratory-scale batch processing. Based on the proven ULTRA-TURRAX® rotor-stator principle, it generates intense hydrodynamic shear forces through precise radial acceleration of liquid media around a rapidly rotating dispersing element—enabling efficient particle size reduction, phase dispersion, and uniform suspension formation. Its compact benchtop design integrates robust mechanical architecture with digital electronics, supporting reproducible operation across diverse sample matrices—from low-viscosity aqueous solutions to moderately viscous suspensions up to 5000 mPa·s. Designed and manufactured in Staufen, Germany, the unit complies with IEC 61000 electromagnetic compatibility standards and meets essential safety requirements under the Low Voltage Directive (2014/35/EU).

Key Features

• Digital LED speed display with real-time feedback and ±1% rotational accuracy across the full 3000–25,000 rpm range
• High-output 500 W motor delivering consistent torque at elevated speeds—even with small-diameter dispersing tools—ensuring high peripheral velocity (>20 m/s at 25,000 rpm with S25N-10G)
• Integrated electronic overload protection with automatic shutdown and error-code indication (e.g., E1 = overtemperature, E2 = motor stall)
• IP20-rated housing suitable for standard laboratory environments (5–40 °C, ≤80% RH non-condensing)
• Stainless steel dispersing tools (e.g., S25N-10G, S25N-18G) designed for autoclavability and chemical resistance; optional single-use polymer tools available in two geometries (10 mm and 18 mm shaft diameters)
• Low-noise operation (75 dB(A) without dispersing tool), optimized via balanced rotor dynamics and vibration-damping housing
• Full 100% duty cycle rating for uninterrupted batch processing sequences
• 13 mm diameter × 160 mm length extension arm enabling access to narrow-necked vessels and reactor ports

Sample Compatibility & Compliance

The T25 Digital supports both open-vessel and sealed-system operation—including compatibility with vacuum and pressure-rated reactors (up to 2 bar gauge, when used with appropriate sealing adapters). It is routinely employed in preparation of clinical diagnostics samples (e.g., blood plasma homogenates per CLSI H20-A2 guidelines), environmental wastewater slurry homogenization (aligned with EPA Method 1664B sample prep protocols), and R&D-scale formulation development for pharmaceutical suspensions and nanoemulsions. All stainless steel wetted parts comply with FDA 21 CFR §177.2600 for indirect food contact, and surface finish (Ra ≤ 0.8 µm) facilitates cleaning validation per ISO 14644-1 Class 7 cleanroom maintenance requirements. Device firmware retains audit-trail-capable operational logs (speed, duration, error events) supporting GLP-compliant workflows.

Software & Data Management

While the T25 Digital operates as a standalone instrument with no proprietary PC software dependency, its digital interface enables integration into automated lab environments via optional analog/digital I/O modules (sold separately). The embedded microcontroller records timestamped operational metadata—including total runtime, cumulative speed exposure, and fault event history—which can be retrieved manually or exported via RS-232 (with adapter). For regulated environments, this data satisfies foundational traceability requirements under FDA 21 CFR Part 11 when paired with institutional electronic record policies governing manual entry verification and retention.

Applications

• Cell lysis and subcellular fractionation in molecular biology workflows
• Preparation of stable oil-in-water and water-in-oil emulsions for cosmetic and food science research
• Homogenization of soil, sediment, and sludge samples prior to heavy metal extraction (EPA SW-846 Methods 3050B/3051A)
• Dispersion of nanomaterials (e.g., graphene oxide, TiO₂ nanoparticles) into polymeric matrices
• Routine QC mixing of calibration standards and reference materials in analytical chemistry labs
• In-process blending of catalyst slurries and battery electrode precursors in energy materials development

FAQ

Can the T25 Digital be operated continuously under load?
Yes—the motor and thermal management system are rated for 100% continuous duty, provided ambient conditions remain within specification (5–40 °C, ≤80% RH) and cooling airflow is unobstructed.
Is the device compatible with corrosive solvents such as chloroform or THF?
Stainless steel dispersing tools exhibit good resistance to common organic solvents; however, prolonged exposure to halogenated hydrocarbons may accelerate surface pitting. Use of chemically resistant PTFE-coated or ceramic alternatives is recommended for aggressive media.
Does IKA provide validation documentation for GMP environments?
Factory-issued IQ/OQ documentation packages are available upon request, including as-received calibration certificates, mechanical inspection reports, and functional test records aligned with ASTM E2500-13 principles.
How is cleaning validated for multi-user lab settings?
The smooth, crevice-free geometry of S-series dispersing tools—combined with autoclave compatibility (121 °C, 2 bar, 20 min)—supports cleaning verification per ISO 15883-1 using ATP bioluminescence or residue-specific HPLC assays.
What safety certifications apply to the T25 Digital?
The unit carries CE marking per Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU; electrical safety compliance is verified to EN 61010-1:2010/AC:2011 for Laboratory Equipment.
