100 per cent protection against cross-contamination: IKA S 18 D - 10 G - KS disposable dispersing tool

In modern and highly sensitive laboratory environments, sample preparation often represents the most critical and error-prone step within the entire analytical chain. Particularly in fields such as forensics, medical diagnostics, PCR analysis or molecular biology research, even the tiniest carry-over of samples – known as cross-contamination – can have disastrous consequences. Not only do they ruin expensive and time-consuming experimental runs, but in the worst-case scenario they can lead to incorrect medical diagnoses or flawed forensic chains of evidence. The IKA S 18 D - 10 G - KS dispersing tool (MPN 0003452400) was developed precisely for these extremely demanding scenarios. This innovative single-use plastic tool, supplied in a cost-effective pack of 12, revolutionises your day-to-day laboratory work and sets entirely new standards in terms of safety, reliability and workflow efficiency.

The problem of cross-contamination and the limitations of stainless steel tools

Whilst traditional stainless steel dispersing tools are durable and robust, they present significant drawbacks when processing highly infectious or DNA-containing samples. To ensure that samples are 100 per cent free of germs and DNA between two samples, a stainless steel tool must be laboriously dismantled after every single dispersing operation, cleaned manually or by machine, and then sterilised at high temperatures in an autoclave. This process not only ties up valuable working time for highly qualified laboratory staff, but also requires the constant use of harsh chemicals and the regular replacement of wear parts such as PTFE bearings. The IKA S 18 D - 10 G - KS completely eliminates this entire cleaning and sterilisation cycle. Once the sample has been homogenised, the plastic tool is simply and safely disposed of in its entirety. This effectively reduces the risk of cross-contamination to zero, whilst at the same time freeing up enormous amounts of staff time and resources in the laboratory, which can then be used for actual analytical work.

Technical superiority in a compact plastic format

Despite being designed as a single-use item (identified by the abbreviation ‘KS’ for plastic), this dispersing tool offers no compromise whatsoever in terms of grinding performance. The tool operates on the tried-and-tested rotor-stator principle and is specifically designed for the high-performance dispersing drives of the IKA T 18 series (such as the T 18 digital, T 18 basic or T 18 mini). With a stator diameter of 10 millimetres (indicated by the “10” in the product designation), it is perfectly sized for processing small to medium sample volumes in the range of 10 to 100 millilitres (based on water). The abbreviation “G” stands for a coarse slot geometry on the stator. This geometry enables optimal suction of the sample into the shear gap and ensures rapid, efficient primary comminution of tough tissue, plant material or solid foodstuffs. Even at maximum speeds of up to 24,000 revolutions per minute, the high-quality plastic remains completely dimensionally stable and produces particle sizes that are ideally suited to downstream extraction processes.

Economic considerations and workflow optimisation

At first glance, the ongoing purchase of disposable tools may appear to be an additional cost factor. However, a detailed full-cost analysis in modern laboratories regularly reveals a very different picture: The purchase cost of an IKA S 18 D - 10 G - KS tool is generally significantly lower than the combined expenditure on labour for manual cleaning, the operating and maintenance costs for autoclaves, expensive chemical cleaning agents, and the regular procurement of spare parts for conventional stainless steel tools. By eliminating set-up and waiting times, laboratories can massively increase their sample throughput. The tool is simply fitted onto the drive, the sample is dispersed, and the tool is then ejected in a single step and disposed of properly.

Numerous areas of application in highly specialised laboratories

The potential applications of this plastic dispersion tool are extremely diverse and cover the most demanding areas of modern analytics. In forensics, it is used for the safe and absolutely contamination-free extraction of DNA or RNA from evidence such as skin, hair or tissue samples. In medical and clinical diagnostics, it enables the rapid homogenisation of biopsies, tumour cells or organ samples for pathology, without the risk of transmitting dangerous pathogens to laboratory staff or other valuable patient samples. This single-use tool is also the absolute first choice for reproducible work in pharmaceutical research – for example, when pulverising coated tablets for active ingredient analysis – or in strictly regulated food safety testing for the detection of pathogenic microorganisms in meat or plant samples.

System integration for maximum safety (splash protection)

To ensure the absolute highest level of user safety, the IKA S 18 D - 10 G - KS dispersing tool can be ideally combined with the appropriate IKA single-use tubes (such as the ET50 tube). This combination creates a fully enclosed system. This protects the user from hazardous, infectious or toxic aerosols that can inevitably be generated during the dispersion process under high centrifugal forces. The system remains completely sealed from homogenisation right through to disposal, which not only physically protects the user but also reliably and permanently prevents contamination of expensive laboratory equipment, pipettes and sterile fume cupboards.

IKA T 18 digital ULTRA-TURRAX disperser, tool-free drive unit, 500 W, 0003720000
Manufacturer number: 0003720000

Anyone who frequently homogenises samples in the laboratory will be familiar with the problem: a good drive alone is not enough; ultimately, it is the right tool that determines the final fineness and throughput. The IKA T 18 digital ULTRA-TURRAX (0003720000) is designed precisely with this in mind. It is supplied as a drive unit only, with a power consumption of 500 watts, which can be freely combined with various S-18 tools for coarse, fine or single-use applications. The LED display shows the set speed – between 3,000 and 25,000 revolutions per minute – at all times, which facilitates reproducible results across multiple test runs. Rotor-stator principle with high shear rates During dispersion, the tool draws the sample in axially and forces it out radially through the narrow slots between the rotor and stator. This briefly generates very high shear rates, which break down solid components and mix liquids into stable emulsions or suspensions. With an output power of 300 watts and a processable volume of 0.001 to 1.5 litres (based on water), the T 18 digital covers typical laboratory batches up to a maximum viscosity of 5,000 mPas. Stepless speed control with LED display The speed can be adjusted continuously between 3,000 and 25,000 rpm, with a deviation of just 1 per cent according to the data sheet. Unlike purely analogue controllers, the LED display shows the set value directly. Once process parameters have been determined, they can be noted down and reproduced exactly for subsequent experiments. With a permissible duty cycle of 100 per cent, prolonged continuous operation is also possible without the drive having to pause in between. The choice of tool determines the result The T 18 digital is deliberately supplied without a dispersing tool, as the most suitable tool depends heavily on the specific sample. The standard S 18 N – 19 G tool with PTFE bearings is suitable for coarse pre-shredding and tougher media, whilst the S 18 N – 10 G offers a narrower gap geometry for finer end products. Those who frequently work with varying samples that are potentially susceptible to contamination will find disposable plastic tools to be a practical alternative, as they rule out cross-contamination between batches from the outset. Typical areas of application As a standalone drive unit, the T 18 digital is particularly suitable for laboratories that already work with a variety of tools or switch specifically between several applications: Preparation of emulsions and suspensions in sample preparation Homogenisation of tissue samples in biology and life sciences research Mixing pigments and fillers into dispersions Routine tasks in quality assurance with varying tool configurations Setting up customised workstations through flexible combination with a stand and tool Selection guide for the T-18 range Drive unit only, complete set or just the tool? The four T-18 variants stocked by us differ primarily in terms of what is included in the scope of delivery and, in the case of the mini-drive, in terms of motor power.

Differences from the neighbouring series If you also require a brushless motor with a timer, the IKA T 18 brushless series offers the next step up: the T 18 brushless digital ULTRA-TURRAX as a drive unit without an attachment, or the T 18 brushless digital Solution as a complete set. Both drive units operate with lower wear than the classic T 18 digital. An overview of all dispersers available from us can be found in the ‘Dispersers’ category; suitable tools are listed under ‘Dispersing Tools’. Application, set-up and maintenance For short-term manual operation, the T 18 digital fits comfortably in the hand; for longer or reproducible processes, it can be securely mounted on a stand, such as the R 1826 plate stand. Operation is permitted at an ambient temperature of 5 to 40 degrees Celsius and a relative humidity of up to 80 per cent at 31 degrees Celsius, decreasing linearly to a maximum of 50 per cent at 40 degrees Celsius. The drive, with protection class IP 20, is not designed for use in damp rooms or outdoors. After each use, the tool used should be dismantled and, depending on the material, cleaned or sterilised before the next procedure begins. At the end of its service life, as an electrical appliance, the drive must not be disposed of with household waste but must be placed in the separate collection for waste electrical and electronic equipment. Individual requirements & procurement service In addition to the standard tools, we supply further accessories for the T 18 digital, such as stands, mounting elements or the Silentstream flow breaker to reduce air ingress during dispersion. Do you require a specific tool, a qualification document or assistance in selecting the right configuration? Through our procurement service, we can assist you with procurement and configuration.
