IKA T18 Basic Digital Display Disperser

Overview

The IKA T18 Basic Digital Display Disperser is a compact, high-performance laboratory dispersing instrument engineered for reproducible homogenization, emulsification, and suspension of liquid-phase samples across research, quality control, and pilot-scale development environments. Based on rotor-stator shear principle—where rotational energy from a high-speed motor is transferred to the sample via a precisely engineered dispersing element—the T18 delivers consistent mechanical energy input within defined process windows. Its design prioritizes operational safety, ergonomic handling, and compatibility with standard laboratory glassware and vessels. Unlike benchtop homogenizers relying solely on magnetic stirring or low-shear mixing, the T18 generates controlled hydrodynamic shear forces essential for particle size reduction, pigment dispersion, cell lysis preparation, and formulation stability assessment. The unit operates without vacuum or temperature control integration, positioning it as a dedicated ambient-condition dispersing solution for routine applications where precision speed control and mechanical robustness are primary requirements.

Key Features

• Electronic speed regulation with analog scale readout and optional digital tachometer interface (DZM) for real-time RPM verification and traceable speed logging
• Integrated electronic overload protection circuitry that automatically interrupts power upon excessive current draw, safeguarding motor windings and extending service life
• Ergonomic quick-release mechanism for dispersing elements—enabling tool-free rotor attachment/detachment in under three seconds without compromising concentricity or sealing integrity
• High-torque 300 W output motor capable of sustaining rated speeds up to 24,000 rpm under load, delivering linear tip speeds exceeding 20 m/s with standard 13 mm rotors
• Compact footprint (65 × 80 × 240 mm) and lightweight construction (1.6 kg) optimized for fume hood integration, mobile lab carts, or shared instrumentation benches
• IP20-rated enclosure compliant with DIN EN 60529 for dry, non-dusty indoor laboratory use; designed for operation within 5–40 °C ambient temperature and ≤80% RH (non-condensing)

Sample Compatibility & Compliance

The T18 accommodates aqueous and low-to-medium viscosity organic media (up to 5,000 mPa·s), including buffers, polymer solutions, suspensions, emulsions, and crude biological lysates. It supports processing volumes from 1 mL (in microcentrifuge tubes using specialized small-diameter rotors) to 1,500 mL (in beakers or cylinders ≥80 mm diameter). While not certified for sterile or explosion-proof environments, its mechanical architecture conforms to general-purpose laboratory equipment safety standards per IEC 61010-1. For regulated workflows—including those aligned with GLP or GMP frameworks—the optional DZM tachometer enables audit-ready speed documentation, supporting 21 CFR Part 11–compatible data capture when integrated with validated LIMS or ELN platforms. Note: Dispersing elements (rotors/stators) are supplied separately and must be selected based on material compatibility (e.g., stainless steel 1.4404/316L for corrosion resistance), geometry (e.g., ULTRA-TURRAX® T18 blades), and vessel dimensions.

Software & Data Management

The T18 Basic model does not incorporate embedded firmware, touchscreen interface, or native USB/Ethernet connectivity. Speed setting and monitoring rely on front-panel analog indication; however, its standardized tachometer signal output (0–10 V DC or pulse train) permits integration with third-party data acquisition systems, programmable logic controllers (PLCs), or custom LabVIEW-based protocols. When paired with the DZM digital tachometer, users obtain calibrated RPM values traceable to national metrology standards—enabling manual entry into electronic lab notebooks or automated import via RS-232/USB adapters. This architecture ensures compatibility with institutional IT security policies restricting networked instrumentation while preserving measurement integrity through hardware-level signal conditioning.

Applications

• Routine dispersion of pigments, nanoparticles, and ceramic slurries in R&D labs developing coatings, inks, and battery electrode slurries
• Preparation of homogeneous suspensions for particle size analysis (e.g., laser diffraction or dynamic light scattering)
• Emulsification of oil-in-water or water-in-oil systems during formulation screening for pharmaceuticals, cosmetics, and food products
• Cell disruption of microbial cultures (e.g., E. coli, yeast) prior to protein extraction—when combined with appropriate rotor geometry and cooling protocols
• Homogenization of tissue homogenates for metabolite profiling or nucleic acid isolation workflows
• QC testing of viscosity stability in industrial lubricants and functional fluids under standardized shear conditions

FAQ

Is the dispersing element included with the T18 Basic unit?
No. All dispersing elements—including ULTRA-TURRAX® rotors (e.g., S18N-10G, S18N-19G), generator heads, and mounting adapters—are sold separately and must be selected according to sample volume, viscosity, and container geometry.
Can the T18 be used for continuous operation?
It is rated for intermittent duty cycles only. Continuous operation beyond 5 minutes at maximum speed requires active cooling of the motor housing and is not recommended without validation per application-specific thermal profiles.
What certifications apply to the T18 for use in regulated laboratories?
The device carries CE marking per EU Machinery Directive 2006/42/EC and EMC Directive 2014/30/EU. Full 21 CFR Part 11 compliance depends on external data capture configuration—not inherent to the base unit.
Does IKA provide calibration services for the T18 or DZM tachometer?
Yes. Accredited calibration certificates (traceable to PTB or NIST) are available through IKA Service Centers upon request, covering both speed accuracy and electrical safety verification.
How does ambient humidity affect long-term reliability?
Operation above 80% RH may accelerate oxidation of internal electrical contacts and reduce insulation resistance over time; use in climate-controlled environments is strongly advised for sustained performance.
