IKA S 10 N - 8 G dispersing tool, Ø 8 mm, 0003305500

The IKA S 10 N - 8 G dispersing tool is a specialised, materials-science-optimised system component designed for precise rotor-stator dispersion in the microlitre and millilitre range. Designed for use with the compact dispersers of the ULTRA-TURRAX T 10 series, this dispersing shaft enables highly efficient sample preparation of sensitive biological, pharmaceutical and chemical media. In applications such as the disruption of tissue cells, the emulsification of cosmetic formulations or the suspension of poorly soluble active ingredients in very small sample vessels, the precise fluid-dynamic geometry of this tool prevents thermal stress on the samples and ensures complete homogenisation. For laboratory managers and procurement officers in industrial research facilities, this tool offers the highest levels of validity and process reliability in accordance with stringent GLP and GMP guidelines.

Rotor-stator kinetics and process-related shear dynamics

The mechanical operating principle is based on the tried-and-tested rotor-stator system, in which the inner rotor moves within the fixed stator at extremely high rotational speeds, preferably up to 30,000 revolutions per minute. Due to the small radial gap between the rotor and stator, the sample medium is drawn axially into the dispersing head and then forced radially through the slots of the generator with enormous kinetic energy. The combination of extremely high shear forces, turbulent shear fields and transient cavitation effects guarantees particle and droplet size reduction down to the micrometre range. The 8 G generator is characterised by an optimised tooth geometry, which enables rapid primary fragmentation of fibrous, tough or cellular sample structures in a single pass.

Material resilience and sterilisation cycles

The material-specific system limits of the dispersing tool are defined by the consistent use of high-quality stainless steel (material number 1.4404 / AISI 316L) and robust PTFE bearings. This material composition ensures outstanding chemical resistance to aggressive acids, alkalis and organic solvents, and gently prevents metallic cross-contamination in multi-user operations. A crucial criterion for molecular biological and microbiological applications is the tool’s unrestricted sterilisability: the entire dispersing tool is fully autoclavable at 121 °C and can be hot-air sterilised up to 180 °C, thereby guaranteeing an absolutely germ-free sample handling process.

Ergonomic design features and working area

The mechanical design features a stator diameter of 8 millimetres and a shaft length of 115 millimetres, enabling reliable operation in deep, narrow reaction vessels and Eppendorf cups. The working range covers a sample volume of 0.5 to 50 millilitres, allowing expensive active ingredients and reagents to be dispensed and processed in a material-efficient manner. Thanks to the shaft’s easy removability, the tool can be cleaned quickly and thoroughly after use, significantly speeding up the laboratory’s workflow and minimising downtime.

Custom requirements & accessories

For the IKA S 10 N - 8 G dispersing tool to operate as intended, a drive unit from the IKA ULTRA-TURRAX T 10 series (e.g. T 10 basic or T 10 digital) is required. To physically prevent abrasive wear of the internal PTFE bearings during dry running, the tool must always be immersed sufficiently deep into the sample medium (min. 20 mm) before switching on. In the event of long-term material fatigue, we stock suitable PTFE replacement seals and manufacturer-approved maintenance kits in our range.
