IKA S 18 D - 14 G - KS disposable dispersing tool (12 pieces), plastic, Ø 14 mm, 0003452300

Maximum safety for larger volumes: the IKA S 18 D - 14 G - KS disposable dispersing tool

In modern analytics, clinical diagnostics and life sciences research, the quality of sample preparation is becoming an increasingly important focus. The IKA S 18 D - 14 G - KS disposable dispersing tool (MPN 0003452300) has been developed specifically for laboratories where absolute purity is the top priority. As a high-performance accessory for the IKA T 18 dispersing drives (such as the T 18 digital or T 18 basic), this tool – made from high-quality medical-grade plastic – offers uncompromising homogenisation performance without the risks associated with traditional reusable systems. Supplied in a practical pack of 12, it is the first choice for daily high-throughput processing of medium to large sample volumes.

The complete elimination of cross-contamination in everyday laboratory work

The greatest enemy of reliable analytical results is sample carry-over, known as cross-contamination. When using conventional stainless steel homogenisation tools, even after the most thorough manual cleaning, microscopic residues of tissue, proteins or nucleic acids (DNA/RNA) often remain trapped in the fine gaps between the rotor and stator or within the PTFE bearing. In highly sensitive procedures such as PCR (polymerase chain reaction) analysis, forensic evidence collection or sequencing, these minute residues can lead to false-positive results. The IKA S 18 D - 14 G - KS completely eliminates this serious risk. As this is a purely single-use product, you use a completely fresh, unused tool for each individual sample. After homogenisation, the entire plastic component, together with the potentially infectious or contaminated sample, is disposed of in accordance with best practice. There is absolutely no need for cleaning, rinsing or autoclaving, which raises process reliability to an unprecedented level.

The 14-millimetre advantage: powerful for medium volumes

In direct comparison with the smaller 10-mm tools, the S 18 D - 14 G - KS model stands out due to its significantly larger stator diameter of 14 millimetres. This design greatly expands the working range: you can homogenise volumes from 10 ml up to 500 ml (based on the viscosity of water) effortlessly and in the shortest possible time. The letter “G” in the product designation stands for a coarse slot geometry on the stator. This open geometry is crucial when dealing with coarse-grained, tough or fibrous feedstock. Plant roots, pieces of meat, tablets or compact food samples are efficiently drawn into the shear gap by the powerful suction forces of the 14 mm rotor, where they are crushed and cut up at speeds of up to 24,000 revolutions per minute. The result is a fine, homogeneous suspension or emulsion that is perfectly prepared for subsequent extraction or analysis.

Cost-effectiveness reimagined: Total Cost of Ownership (TCO)

A common objection to single-use laboratory items is the seemingly higher cost of materials. However, when a realistic total cost of ownership (TCO) analysis is carried out, the IKA S 18 D system often proves to be the significantly more cost-effective solution. Consider the hidden costs of a stainless steel tool: highly qualified laboratory staff spend hours every day dismantling, scrubbing and reassembling the tools. Added to this are the running costs for distilled water, aggressive cleaning chemicals, energy consumption and the maintenance of autoclaves, as well as the inevitable wear and tear on ball bearings and seals. The single-use plastic tool S 18 D – 14 G – KS eliminates the need for all these steps. You drastically reduce your labour costs per sample, minimise downtime and can significantly increase throughput in your laboratory. Staff can focus on value-adding analytical tasks rather than carrying out washing duties.

A wide range of applications in strictly regulated environments

The areas of application for the 14 mm plastic tool are as diverse as they are demanding. In food testing, it is used to detect pesticide residues or pathogenic organisms in large meat or vegetable samples without carrying allergens from one sample to the next. In clinical pathology, it enables the safe processing of infected patient tissue. In pharmaceutical research, it is indispensable for the homogeneous pulverisation of pharmaceutical formulations for active ingredient release testing.

Maximum user protection through system integration

For work with particularly critical media, the tool offers a further unbeatable advantage: it can be perfectly combined with IKA disposable tubes (e.g. the ET50 tube). Simply attaching the tube to the tool shaft creates a completely self-contained system. When dispersing at maximum speed, hazardous aerosols, toxic vapours or infectious splashes cannot escape into the laboratory environment or the fume cupboard. This not only protects your valuable analytical equipment from contamination, but above all safeguards the health of your staff.

Individual requirements & accessories

To further maximise your safety in the laboratory, we recommend using the matching IKA ET50 disposable tubes, which fit seamlessly onto the shaft of this tool and serve as a reliable splash guard. Is 500 ml too large for your application? Then simply switch to the 10 mm version (S 18 D - 10 G - KS) for smaller volumes up to 100 ml. Our procurement service will be happy to assist you in selecting the optimal tool sizes for your Standard Operating Procedures (SOPs).
