IKA T 25 Digital ULTRA-TURRAX® High-Performance Disperser

Overview

The IKA T 25 Digital ULTRA-TURRAX® is a high-torque, digitally controlled high-shear disperser engineered for precision batch processing in research laboratories, quality control environments, and pilot-scale development workflows. Based on the proven rotor-stator principle—where fluid samples are subjected to intense hydrodynamic shear, cavitation, and turbulent mixing within the narrow gap between a rapidly rotating rotor and fixed stator—the T 25 Digital delivers reproducible dispersion, emulsification, homogenization, and cell disruption across a broad range of viscosities and sample volumes. Its robust 500 W output motor enables stable operation at speeds up to 25,000 rpm, generating tip speeds exceeding 3,000 m/min with standard S-shaped dispersing elements—critical for breaking down agglomerates, deagglomerating nanoparticles, and achieving sub-micron emulsion droplets. Designed for integration into GLP-compliant workflows, the instrument meets essential electrical safety and electromagnetic compatibility requirements per DIN EN 60529 (IP20) and IEC 61000 standards.

Key Features

• Digital LED speed display with real-time feedback and ±1 % speed accuracy—enabling precise method replication and audit-ready parameter logging
• Stepless electronic speed control via rotary encoder, allowing fine-grained adjustment across the full 3,000–25,000 rpm range
• Integrated electronic overload protection with automatic shutdown and error code display (e.g., E1 = overtemperature, E2 = motor stall)
• Stainless steel dispersing tools (S-type, R-type, and C-type) designed for autoclavability, chemical resistance, and rapid cleaning—reducing cross-contamination risk
• Two sizes of sterile, single-use dispersing elements (Ø10 mm and Ø18 mm) compatible with ISO 5 cleanroom protocols and diagnostic sample preparation
• Low-noise mechanical architecture (75 dB(A) without dispersing head) optimized for shared laboratory spaces and noise-sensitive environments
• 13 mm diameter, 160 mm long aluminum-alloy extension arm supporting vertical immersion depth control and compatibility with jacketed reactors or vacuum/pressure vessels
• 100 % duty cycle rating—validated for uninterrupted operation during extended batch sequences without thermal derating

Sample Compatibility & Compliance

The T 25 Digital accommodates aqueous, organic, and semi-viscous media—from low-viscosity buffers (1 mPa·s) to structured gels and suspensions up to 5,000 mPa·s. It supports processing under ambient, reduced-pressure (vacuum), or pressurized conditions when coupled with appropriate reactor lids and sealing interfaces—making it suitable for oxygen-sensitive formulations or volatile solvent systems. All wetted parts comply with USP Class VI biocompatibility requirements; stainless steel components meet ASTM A276 and EN 10088-1 standards. The unit is routinely deployed in applications aligned with ISO 17025-accredited testing labs and satisfies foundational instrumentation requirements for FDA 21 CFR Part 11–aligned workflows when paired with compliant data capture software (see Software & Data Management section).

Software & Data Management

While the T 25 Digital operates as a standalone instrument, its digital interface enables seamless integration with IKA’s Labworldsoft® PC software suite (optional). Labworldsoft® provides time-stamped speed logging, method archiving, user access control (with role-based permissions), and electronic signature support—facilitating compliance with GLP, GMP, and ISO/IEC 17025 documentation mandates. Audit trails record all parameter changes, start/stop events, and error codes with immutable timestamps. Raw speed data exports to CSV or Excel formats for statistical process analysis (SPC), trending, and regulatory submission packages. For fully validated environments, optional RS232 or USB-to-serial adapters enable connection to LIMS or ELN platforms supporting ASTM E2500-defined instrument qualification protocols.

Applications

• Preparation of homogeneous suspensions for pharmaceutical suspension dosage forms (per USP and )
• Cell lysis and nucleic acid extraction in molecular diagnostics workflows
• Emulsification of oil-in-water and water-in-oil systems for cosmetic and food R&D
• Dispersion of carbon nanotubes, graphene oxide, and metal oxide nanoparticles in polymer matrices
• Homogenization of wastewater sludge and environmental sediment samples prior to ICP-MS or GC-MS analysis
• In-process blending of catalyst slurries and battery electrode slurries in energy materials development
• Rapid deagglomeration of pigment concentrates for inkjet formulation and coating viscosity optimization

FAQ

Can the T 25 Digital be used in explosion-proof environments?
No—this model lacks ATEX or IECEx certification and is not rated for use in hazardous areas classified under Directive 2014/34/EU.
Is continuous operation possible at maximum speed (25,000 rpm)?
Yes—rated for 100 % duty cycle; however, sustained operation above 20,000 rpm with high-viscosity media (>2,000 mPa·s) requires active cooling of the sample vessel to prevent thermal degradation.
Are replacement dispersing elements traceable to lot-specific certificates of conformance?
Yes—original IKA dispersing tools ship with material test reports (MTRs) and dimensional inspection records upon request for regulated applications.
Does the instrument support external trigger signals for synchronized start/stop?
Not natively—the T 25 Digital does not feature TTL or analog input ports; synchronization must be achieved via Labworldsoft® software scripting or external PLC interfacing through optional I/O modules.
What is the recommended calibration interval for speed verification?
IKA recommends annual speed calibration using a NIST-traceable tachometer; internal self-diagnostics verify encoder function daily during power-up.
