IKA T 25 mini control ULTRA-TURRAX® Disperser

Overview

The IKA T 25 mini control ULTRA-TURRAX® is a compact, high-performance laboratory disperser engineered for precise batch processing of low-to-medium viscosity samples requiring efficient homogenization, emulsification, dispersion, and particle size reduction down to the micrometer range. Based on the proven ULTRA-TURRAX® rotor-stator principle—where fluid dynamics generate intense shear forces through controlled laminar and turbulent flow within the narrow gap between rotating and stationary elements—the instrument delivers reproducible results across diverse sample matrices. Its brushless DC motor ensures stable torque delivery across the full speed range (600–25,000 rpm), eliminates carbon dust contamination, reduces acoustic emissions (<75 dB(A) without dispersing tool), and extends operational lifetime. Designed for benchtop integration in regulated environments—including QC labs operating under GLP or GMP frameworks—the unit complies with DIN EN 60529 (IP 30) and supports traceable parameter logging via integrated digital interfaces.

Key Features

• Brushless DC motor with continuous speed control (600–25,000 rpm) and ±3 % speed accuracy for consistent shear energy input
• TFT-enhanced LED display enabling clear parameter visibility at distance; real-time monitoring of speed, temperature (0–125 °C), and timer status
• Integrated temperature sensor with 0.1 K resolution and ±1 K accuracy—enabling process-critical thermal profiling during exothermic dispersion
• Multi-protocol connectivity: RS 232, USB, Bluetooth, Wi-Fi, and Ethernet—supporting remote operation, firmware updates, and audit-ready data export
• Modular mechanical design compatible with the full S25 series of dispersing tools (max. stator diameter: 18 mm); rapid tool attachment/detachment without tools
• Compact footprint (66 × 186 × 100 mm) and lightweight construction (1.8 kg) optimized for fume hoods, biosafety cabinets, and space-constrained analytical workstations
• 100 % continuous duty rating with thermal overload protection; standby power consumption limited to 3 W

Sample Compatibility & Compliance

The T 25 mini control accepts aqueous, organic, and semi-aqueous systems with viscosities up to 2000 mPa·s and volumes from 1 mL to 1.5 L (H₂O-equivalent). It supports ISO 8504-2-compliant dispersion protocols for pigment preparation, ASTM D4290 for polymer dispersion stability assessment, and USP light scattering validation workflows when paired with appropriate optical detection modules. All electrical interfaces conform to IEC 61000-6-3 (EMC emission) and IEC 61000-6-2 (immunity) standards. The device meets FDA 21 CFR Part 11 requirements for electronic records and signatures when used with IKA labworldsoft® v4.0+ (configured with user access control, electronic audit trail, and data integrity safeguards).

Software & Data Management

IKA labworldsoft® software enables full remote configuration, real-time parameter acquisition, and time-stamped method archiving. Each session generates a structured CSV or PDF report including operator ID, timestamp, speed profile, temperature curve, and total run duration—fully compliant with ALCOA+ (Attributable, Legible, Contemporaneous, Original, Accurate, Complete, Consistent, Enduring, Available) data governance principles. USB and Ethernet connections support automated backup to network drives or LIMS-integrated repositories. Bluetooth/Wi-Fi modes allow tablet-based operation while maintaining secure TLS 1.2 encrypted communication channels.

Applications

• Preparation of stable oil-in-water and water-in-oil emulsions for pharmaceutical formulations and cosmetic R&D
• Dispersion of nanomaterials (e.g., graphene oxide, TiO₂ nanoparticles) in aqueous or ethanol suspensions
• Homogenization of tissue lysates and bacterial cell suspensions prior to nucleic acid extraction
• Deagglomeration of pigment concentrates and ceramic slurries for coating development
• Routine QC testing of surfactant efficiency and colloidal stability per ISO 13320 laser diffraction correlation protocols
• Accelerated aging studies requiring controlled shear stress application over defined time intervals

FAQ

Is the dispersing tool included with the T 25 mini control unit?
No. Dispersing tools (S25 series) are sold separately to allow selection based on specific application requirements—including stainless steel, PTFE-coated, and disposable plastic variants.
Can the device operate continuously for extended periods?
Yes. The system is rated for 100 % continuous duty cycle with built-in thermal management and automatic shutdown at critical temperatures.
Does the temperature sensor measure sample temperature directly?
The integrated Pt100 sensor measures temperature at the shaft interface; for direct sample measurement, an external probe-compatible adapter (e.g., PT-10) must be used.
Which regulatory standards does the instrument support for data integrity?
When configured with labworldsoft® and appropriate user management, it satisfies FDA 21 CFR Part 11, EU Annex 11, and ISO/IEC 17025 documentation requirements.
What is the maximum permissible ambient humidity for safe operation?
Relative humidity must not exceed 80 % non-condensing, as specified in the IEC 60529 IP 30 rating.
