IKA S 18 N - 19 G Dispersing tool, coarse, PTFE bearings, 10 to 1,500 ml, L004640
The IKA S 18 N – 19 G (L004640) is the standard tool for coarse dispersion tasks on the IKA T 18 series drives, such as the T 18 digital ULTRA-TURRAX. The stainless steel tool covers a working range of 0.01 to 1.5 litres (10 to 1,500 millilitres, based on water) and is therefore the obvious choice for day-to-day sample preparation when rapid grinding and mixing are required. Toothed geometry for pre-grinding The letter G in the model designation stands for ‘coarse’. Unlike fine-grinding tools, the stator of this model features a coarsely serrated geometry with a gap width of 0.25 millimetres between the rotor and stator. This makes the S 18 N - 19 G the obvious choice for the pre-grinding of solid sample components, the mixing of pigments or fillers into coarse suspensions, and for viscous media that could clog finer tools. PTFE bearings for contact with aggressive media The rotor shaft is mounted in a PTFE bearing, as indicated by the letter ‘N’ in the model designation. PTFE is chemically almost inert, meaning the tool can be used with aggressive solvents, acids and alkalis without the bearing being affected. One important application note remains: PTFE bearings rely on the medium for lubrication and cooling; the tool must therefore not run dry, otherwise the resulting frictional heat will destroy the bearing. Hygiene and material quality Manufactured from electropolished AISI 316L stainless steel, the tool meets high hygiene standards. It is corrosion-resistant, durable and can be easily dismantled and sterilised for applications in the medical or microbiological fields, whether by chemical disinfection, dry heat or in an autoclave. This prevents cross-contamination between different sample batches. Typical applications According to the manufacturer, the S 18 N - 19 G is designed as a dispersing tool for the T 18 digital drive for volumes ranging from 10 to 1,500 millilitres. In practice, it is suitable for: Preliminary grinding of solid components in liquid samples Coarse suspensions containing pigments or fillers Viscous media that would be too viscous for finer tools Sample preparation with high requirements for chemical resistance Selection guide within the tool range In addition to the coarse version described here, LT Laborhandel stocks further tools for the T-18 drives with different gap geometries or made from different materials. The S 18 N - 10 G, with a narrower gap width, is suitable for finer end products; for single-use requirements and applications where no cleaning is required between samples, the plastic tools S 18 D - 10 G - KS and S 18 D - 14 G - KS are available.

According to the manufacturer’s compatibility information, it is also compatible with the brushless drives T 18 brushless digital ULTRA-TURRAX, T 18 brushless digital Solution and the compact T 18 mini digital ULTRA-TURRAX. Use, maintenance and disposal Before first use, the tool should be securely screwed onto the drive unit and checked to ensure it is firmly in place. During operation, the tool must remain fully submerged in the medium at all times; the immersion depth ranges from 35 to 170 millimetres, depending on the container. After use, the tool can be detached from the drive unit for cleaning and, depending on requirements, chemically disinfected, treated with dry heat or autoclaved. As an accessory to an electrical appliance, the end-of-life tool must not be disposed of with household waste, but must be disposed of properly together with the associated drive unit.

IKA S 18 N - 10 G dispersing tool, Ø 10 mm, L004639
The IKA S 18 N - 10 G dispersing tool is a specialised, materials-science-optimised system component designed for precise rotor-stator dispersion in the millilitre range. Designed for use with the high-performance laboratory dispersers of the ULTRA-TURRAX T 18 series, this dispersing shaft enables highly efficient sample preparation of 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 laboratory vessels, the precise fluid-dynamic geometry of this tool prevents thermal stress on samples and ensures complete homogenisation. For laboratory managers and procurement officers in industrial research facilities, this tool offers the highest level of validity and process reliability in accordance with stringent GLP and GMP guidelines. Rotor-stator kinetics and process 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 of up to 25,000 revolutions per minute. Due to the small radial gap between the rotor and stator, the sample medium is drawn axially into the dispersion 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 10 G generator is characterised by an optimised tooth geometry, which enables rapid primary fragmentation of fibrous, tough or cellular sample structures across an extended volume range. 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 a robust PTFE bearing. 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 instrument’s unrestricted sterilisability: the entire dispersing instrument 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 10 millimetres and a shaft length of 108 millimetres, enabling reliable operation in various reaction vessels and laboratory glassware. The working range covers a sample volume of 1 to 100 millilitres, allowing flexible sample series to be processed efficiently whilst minimising material wastage. Thanks to the shaft’s easy disassembly, the tool can be cleaned quickly and thoroughly after use, significantly speeding up the laboratory’s workflow and minimising downtime.

Individual requirements & accessories For the IKA S 18 N - 10 G dispersing tool to operate as intended, a drive unit from the IKA ULTRA-TURRAX T 18 series (e.g. T 18 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.

IKA S 25 N - 25 F Dispersing tool, fine, PTFE bearings, 100–2000 ml, 0001713800
The finest particles for the most demanding requirements: the IKA S 25 N – 25 F The IKA S 25 N – 25 F (MPN 0001713800) is a high-performance dispersing tool specially developed for applications where particularly fine particle sizes are required. Compatible with the drive units of the IKA T 25 series (e.g. T 25 digital, T 25 easy clean), this tool transforms your disperser into a precision instrument for demanding emulsification and suspension tasks. It covers a working range from 100 ml to 2,000 ml (H₂O), making it the ideal all-rounder for medium-sized laboratory batches. The ‘F’ makes all the difference: rotor-stator geometry for fine results At IKA, the designation “F” stands for “Fine”. In contrast to the standard version (“G”=“Coarse”), this tool features a specially designed rotor-stator geometry with narrower slots and smaller clearances. This results in higher shear rates and more intensive mechanical processing of the sample. The result is significantly smaller particle sizes and more stable emulsions. This makes the S 25 N - 25 F ideal for the production of creams and lotions in cosmetic development, the homogenisation of dairy products, or the fine grinding of fibrous samples that have already been pre-ground. PTFE bearings (“N”) for universal resistance The “N” in the model designation indicates the type of bearing used: high-quality PTFE (polytetrafluoroethylene) is employed here. PTFE bearings are characterised by their excellent chemical resistance to almost all acids, alkalis and solvents. They also minimise heat build-up in the bearing area. Note: Tools with PTFE bearings are ideal for liquid applications, but must never be run dry, as the bearing is lubricated and cooled by the medium. Running the bearing dry would destroy it immediately. Material Quality and Hygiene All parts in contact with the medium are made from high-quality stainless steel (AISI 316L). This material is not only extremely corrosion-resistant but also meets the high hygiene requirements of the pharmaceutical and food industries. The tool is designed for operating temperatures of up to 180 °C and can be easily dismantled for cleaning and sterilisation. It is compatible with all standard sterilisation methods – including autoclaving (wet sterilisation) – which guarantees sterile operation in microbiological applications. Easy handling and maintenance Thanks to its standardised shank design, the S 25 N - 25 F can be mounted quickly and securely onto T 25 drives. Cleaning is straightforward thanks to its well-thought-out design: the tool can be dismantled into its individual parts in just a few simple steps to remove all residues and reliably prevent cross-contamination. Technical data Compatible drives: IKA T 25 digital, T 25 easy clean (digital/control) Working range (H₂O): 100 – 2,000 ml Stator diameter: 25 mm Rotor diameter: 18 mm Version: F = Fine Bearing: N = PTFE bearing Material (in contact with the medium): Stainless steel (AISI 316L), PTFE Max. temperature: 180 °C Sterilisation methods: All (including autoclaving) Generator gap: 0.5 mm Immersion depth: 40 – 165 mm Screw-in shaft: Yes Contents 1 x IKA S 25 N - 25 F dispersing tool Operating instructions (often included in the drive manual or supplied separately) Individual requirements & accessories Do you require tools for larger volumes, cutting tools (S 25 N – 25 G) for coarse pre-shredding, or special ceramic seals (‘K’ series) for vacuum applications?

IKA S 25 N - 18 G - ST Dispersing tool, sawtooth, PTFE bearing, 10–1500 ml, 0004447300
The cutting specialist for fibrous media: IKA S 25 N - 18 G - ST With the S 25 N - 18 G - ST dispersing tool (MPN 0004447300), you can expand the range of applications for your IKA T 25 disperser (e.g. T 25 digital or T 25 easy clean) to include a crucial capability: the effective comminution of fibrous and viscous structures. Whilst conventional rotor-stator systems often become blocked with long-fibre samples or merely wrap the fibres around the rotor, this specialised tool reliably cuts them into small pieces. It covers a working volume range of 10 ml to 1,500 ml (H₂O) and is therefore ideal for sample preparation in biology, food chemistry or environmental analysis. Sawtooth technology (“ST”) for maximum cutting efficiency The abbreviation “ST” stands for “Saw Tooth”. If you look closely at the generator head, you can see its unique geometry: the stator ring is not only slotted but also features a serrated cutting edge. In combination with the high-speed rotating blade rotor, the system acts like a pair of extremely efficient scissors. This design makes the tool ideal for demanding tasks such as: Tissue disruption: shredding of muscle tissue, tendons or skin in medical diagnostics. Plant samples: homogenisation of leaves, roots or fibrous vegetables (e.g. asparagus, leeks). Material analysis: Processing of paper, pulp or textile samples. Durable and chemically resistant thanks to PTFE bearing (“N”) Like all “N” tools in the S 25 series, this model is also fitted with a high-quality PTFE bearing. PTFE (Teflon) is chemically almost inert and easily withstands aggressive acids, bases and solvents. This makes the tool universally applicable, regardless of the dispersing medium. Important note: As PTFE bearings require the medium for lubrication and cooling, the tool must not be allowed to run dry. Running dry would lead to immediate overheating and destruction of the bearings. Pharmaceutical-grade stainless steel The shaft and the generator elements are made of high-quality stainless steel (AISI 316L). This material is not only robust and rust-resistant, but also meets all hygiene requirements for use in the laboratory. The tool is designed for temperatures up to 180 °C and can be completely dismantled for cleaning. For sterile applications, the entire tool can be autoclaved (wet sterilisation) or sterilised with hot air, which effectively prevents cross-contamination. Easy replacement and cleaning Thanks to the standardised coupling, the S 25 N - 18 G - ST can be fitted to all drives in the T 25 range in a matter of seconds. It can be dismantled for cleaning without the need for special tools, ensuring that fibre residues can be safely removed from the cutting head. Technical data Compatible drives: IKA T 25 digital, T 25 easy clean (digital/control) Working range (H₂O): 10 – 1,500 ml Stator diameter: 18 mm Rotor diameter: 12.7 mm Design: G - ST (coarse with sawtooth) Bearing: N=PTFE bearing Material (in contact with the medium): Stainless steel (AISI 316L), PTFE Max. temperature: 180 °C Generator gap: 0.5 mm Immersion depth: 40 – 165 mm Sterilisation: All methods (fully autoclavable) Special feature: Cutting head for fibrous samples Contents of delivery 1 x IKA dispersing tool S 25 N - 18 G - ST Operating instructions (included with the drive or supplied separately) Individual requirements & accessories If you need to process extremely hard samples (e.g. tablets, bones), we may recommend using a pre-processing mill (e.g. IKA Tube Mill) instead of the cutting tools. For standard emulsions without fibres, it is better to use the classic “G” or “F” version without a serrated edge. Please contact our procurement service for application advice.

IKA S 50 N - G 45 G - ST dispersing tool, sawtooth design, 0008039500
The IKA S 50 N - G 45 G - ST dispersing tool represents a high-purity and extremely powerful fluid-mechanical system solution for the professional comminution, homogenisation and suspension of demanding sample media on a laboratory and pilot-plant scale. This precision-manufactured rotor-stator system has been specifically validated for use with the high-performance IKA dispersing drives of the ULTRA-TURRAX T 50 series. In complex processes within the pharmaceutical processing industry, food analysis, biotechnology or pulp research, the disruption of viscous, fibrous or elastic sample structures is the primary criterion for producing homogeneous suspensions in a gentle and time-efficient manner for subsequent analytical steps. Fluid-mechanical comminution via sawtooth geometry The process-engineering heart of the tool is the generator in a special ST (Saw Tooth) design. The distinctive geometry of the saw teeth on the rotor and stator generates extremely high mechanical impact, cutting and shear forces in the transient shear gap. This mechanical kinetics is ideally designed to cut and disintegrate fibrous matrices – such as tissue structures, plant parts, tobacco, paper and wood pulps, as well as tough plastics or viscous emulsions – in a flash. Uncontrolled wrapping of fibres around the shaft is prevented by the flow-optimised tooth arrangement, ensuring gentle handling of the material and process reliability. Material-related inertness and uncompromising sterilisability The materials science design of the dispersing rod is consistently optimised for maximum chemical resilience and absolute freedom from contamination. All functional elements in contact with the medium are made of high-purity, stainless steel grade 1.4404 (AISI 316L). The shaft is supported by an extremely low-friction and wear-resistant PTFE bearing system. This combination of materials allows for continuous use in aggressive acids, alkalis and organic solvents. To ensure a sterile sampling environment and to completely rule out cross-contamination in multi-user operation, the entire tool can be easily sterilised in an autoclave or cleaned gently with standard disinfectants. Process reliability and convenient system integration The mechatronic system architecture guarantees safe and vibration-free power transmission even at maximum speeds of up to 10,000 revolutions per minute. The dispersing shaft can be quickly and tool-free secured in the T 50 digital drive via the standardised connection. Thanks to the generous immersion depth of up to 250 mm and the fluid-mechanical geometry, the tool is certified for a wide working volume ranging from 0.5 to 20 litres (based on water). This offers laboratory managers and industrial users maximum flexibility when scaling up processes from research to pilot plant scale. Technical details Metrology & Dispersion Specifications Tool type: Rotor-stator dispersing tool Model designation: S 50 N - G 45 G - ST Operating range (volume range for H₂O): 0.5 to 20 litres Generator design: G (Coarse) with ST geometry (sawtooth) Maximum speed range: 10,000 rpm Maximum peripheral speed: approx. 18.8 m/s Design, materials & geometry Materials in contact with the medium: Stainless steel 1.4404 (AISI 316L), PTFE Stator diameter: 45 mm Rotor diameter: 36 mm Shear gap (distance): approx. 0.5 mm Minimum immersion depth: 70 mm Max. immersion depth: 250 mm Shaft diameter: 30 mm Overall length: 290 mm Operating conditions & cleaning Solvent resistance: Yes (universal chemical resistance) Cleaning: Autoclavable (up to 121 degrees Celsius) and hot-air sterilisable (up to 180 degrees Celsius) Bearing type: PTFE plain bearing (shaft-guided, low-maintenance) Contents 1 x IKA S 50 N - G 45 G - ST dispersing tool (MPN: 0008039500) 1 x Operating instructions / Quality certificate Important note: The required dispersing drive (e.g. IKA ULTRA-TURRAX T 50 digital), stand fixtures, cross-sockets and sample vessels are not included in the standard scope of delivery and must be configured separately.

IKA S 25 KD - LR - 25 G dispersing tool (for laboratory reactors), 0025007321
The IKA S 25 KD - LR - 25 G is a specialised dispersing tool designed primarily for use in IKA laboratory reactors (LR series). The distinctive feature of this tool lies in its geometric design: it has an extended shaft (267 mm installation length), which allows for deeper immersion into reactor vessels. This is crucial for ensuring efficient homogenisation even at low liquid levels or with small sample volumes, without the reactor needing to be filled to the brim. KD design for vacuum and cleaning The abbreviation ‘KD’ stands for a special sealing and bearing design that allows operation under vacuum down to 100 mbar. This makes the tool ideal for processes where air ingress must be avoided or which take place under reduced pressure (e.g. degassing during dispersion). At the same time, the KD design enables tool-free disassembly: the rotor can be easily removed, which significantly facilitates cleaning and sterilisation (wet chemical or autoclave) and prevents cross-contamination. Material quality and FDA compliance All parts in contact with the product are manufactured from high-quality materials: stainless steel (AISI 316L), PTFE and FFPM. This combination not only ensures high chemical resistance (pH 2–13) and solvent compatibility, but also meets the strict requirements of the FDA. This makes the tool ideally suited for applications in pharmaceutical and food development, where the highest levels of purity are required.

IKA TS 25-3 Cleaning tool, cleaning tool for T 25 disperser, 0020003013
Maximum analytical reliability through impeccable hygiene: the IKA TS 25-3 Cleaning Tool In modern laboratory practice – be it in strictly regulated pharmaceutical quality control, highly sensitive food analysis or microbiological research – sample preparation is by far the most critical step. High-performance dispersing tools break down tissue, emulsify oils or suspend powders using immense shear forces. In the process, microscopically small sample particles are inevitably forced deep into the narrow gap between the rotor and stator, as well as into the tool’s internal plain bearings. If these residues are not removed one hundred per cent after every single sample, there is a risk of the dreaded cross-contamination (carry-over). Even invisible traces of DNA, allergens or active pharmaceutical ingredients from the previous sample can completely skew the subsequent analysis, leading to fatal misinterpretations or costly product recalls. Manually scrubbing the sharp-edged tools under running water is not only extremely time-consuming, but also poses a high risk of injury to laboratory staff. To standardise this essential cleaning process, make it safer and significantly speed it up, IKA has developed the TS 25-3 Cleaning Tool (MPN 0020003013). This intelligent cleaning system is the ultimate solution for all users of the T 25 disperser series who cannot afford to compromise on the cleanliness of their instruments. The systematic 3-stage cleaning procedure At the heart of the IKA TS 25-3 system lies not only the hardware itself, but also the establishment of a validatable Standard Operating Procedure (SOP) for your laboratory. With this tool, IKA recommends a precisely defined and highly effective cleaning process comprising three consecutive steps: Pre-cleaning (solvent): In the first step, coarse contamination is removed. The contaminated dispersing tool is inserted into the first tube, which is filled with a solvent suitable for your sample. Switching on the dispersing drive creates a powerful suction that forces the solvent through the shear gap with high kinetic energy, mechanically and chemically dislodging even stubborn, greasy or sticky residues. Main cleaning (cleaning agent): In the second step, you move on to the next tube, which is filled with a specific laboratory cleaning agent (surfactant mixture). Here, proteins are denatured, fats are emulsified and any remaining organic or inorganic deposits are separated from the tool’s high-quality stainless steel at a molecular level. Final cleaning (rinsing): The third and final step takes place in the last tube, which contains pure, demineralised water. This rinsing cycle thoroughly washes all remaining traces of the previously used solvents and cleaning agents out of the tool. The result is a chemically pure, residue-free dispersion tool that is immediately ready for the next highly sensitive sample. Occupational health and safety at the highest level In addition to analytical purity, the TS 25-3 Cleaning Tool offers an invaluable advantage in terms of occupational health and safety. When solvents or aggressive surfactants are dispersed openly in a beaker to clean a tool, dangerous aerosols are inevitably produced, which can be inhaled by laboratory staff. The TS 25-3 system eliminates this hazard. The ingenious tube holder secures the three supplied tubes firmly and stably. Thanks to the matching caps, the cleaning process takes place in a largely enclosed system. This effectively prevents toxic solvents or hot cleaning solutions from being sprayed out. It also eliminates the need for dangerous manual handling with brushes near the razor-sharp, rotating blades of the dispersing tool. Comprehensive compatibility with the T 25 ecosystem IKA has seamlessly integrated this cleaning tool into its existing product portfolio. The TS 25-3 Cleaning Tool is designed exclusively for use in combination with the globally proven high-performance dispersers of the T 25 class, namely the T 25 digital and the modern high-tech drives T 25 easy clean digital and T 25 easy clean control. In terms of tools, the system covers an enormous range. It has been specifically developed for cleaning a wide variety of stainless steel dispersing tools, including models from the S 25 N series (e.g. S25N-18G/18G-ST, S25N-25G/F/25G-ST), the S 25 KR series (e.g. S25KR-18G/18G-ST, S25KR-25G/25F/25G-ST) and the vacuum-sealed S 25 KV series (S25KV-18G/25G/25F). Cost-effectiveness and Total Cost of Ownership (TCO) At first glance, a specialised cleaning tool may seem like nothing more than a luxury item. However, if a detailed full-cost analysis is carried out, the TS 25-3 pays for itself extremely quickly in laboratories with high sample throughput. The working time saved by highly qualified laboratory staff, who no longer have to stand at the sink for minutes on end, is considerable. Far more crucial, however, is the extension of the service life of your expensive dispersing tools. Improper manual cleaning often leads to microscopic scratches on the stator or damage to the sensitive plain bearings caused by dried-on sample residues. Hydrodynamic cleaning in the TS 25-3 is gentle on the material, prevents shafts from seizing up and thus massively reduces your ongoing spare parts costs. Investing in the IKA TS 25-3 Cleaning Tool means investing in certifiable process reliability, the protection of your staff and the uncompromising reliability of your analytical results.

IKA S 25 KV - 26 LR Dissolver Agitator, High Speed, Ø 26 mm, 0020015397
Maximum efficiency in dissolution and deagglomeration: the IKA S 25 KV - 26 LR dissolver The IKA S 25 KV - 26 LR dissolver (MPN 0020015397) represents the very pinnacle of modern mixing and dispersion technology for demanding laboratory reactor systems. In many industrial and research sectors – be it in chemical synthesis, cosmetics development, paint production or food technology – users face the significant daily challenge of homogeneously incorporating fine powders, highly cohesive solids or sticky pigments into liquid media. Very often, stubborn agglomerates form when these solids are stirred in. These disruptive clumps of particles are simply moved in circles by conventional agitators such as propeller, paddle or anchor agitators, but are not effectively broken up mechanically. The result is incomplete reactions, poor textures or significantly prolonged process times. This high-speed dissolver was designed precisely for these critical and energy-intensive process steps. It delivers uncompromising performance in intensive mixing, dissolution and deagglomeration to ensure homogeneous, completely lump-free dispersions in the shortest possible time. The aerodynamic dissolver principle In direct comparison to a conventional rotor-stator dispersing tool, in which the medium is forced through a very narrow, defined gap between two components, the S 25 KV - 26 LR model utilises a specially serrated dissolver disc with a diameter of 26 millimetres. This solid metal disc rotates freely at extremely high speeds (high speed) within the liquid medium. The sharp teeth on the edge of the disc, which are alternately curved upwards and downwards, generate immense local shear forces and strong turbulence. The rotation accelerates the liquid radially outwards with great force, which simultaneously creates an enormous axial suction effect (vortex formation) at the centre. This intelligent flow pattern draws the floating or agglomerated powder particles from the liquid surface directly downwards towards the rotating toothed disc. There, they are literally shattered by the high kinetic energy of the teeth and broken down into their fine primary particles. In process engineering, this principle is the absolute gold standard method for the rapid incorporation of poorly wettable thickeners, colour pigments or high-molecular-weight polymers into aqueous or highly solvent-based systems. Vacuum and pressure tightness (the ‘KV’ seal) Another outstanding feature of this stirring tool, which is indispensable for many applications, is indicated by the specific abbreviation ‘KV’. In IKA products, this stands for a high-quality ball bearing system combined with a special sealing technology that makes the tool absolutely vacuum- and pressure-tight (up to the respective system-specific limits of the laboratory reactors). When working professionally with state-of-the-art laboratory reactors such as the IKA LR 1000 control System or the versatile LR-2.ST series, this leak-tightness is of fundamental importance. Sensitive chemical reactions or the production of high-purity cosmetics and emulsions often require the strict exclusion of oxygen. Users must work under a protective inert gas atmosphere or specifically degas the sample under vacuum to avoid disruptive air pockets in pasty, viscous media. A conventional, open dispersing tool would cause the reactor chamber to leak under these extreme conditions and ruin the process. The S 25 KV - 26 LR dissolver agitator, on the other hand, seals the reactor opening absolutely securely via the flange. This allows you to deagglomerate your samples at full high-speed rotation whilst a strong vacuum is maintained inside the vessel – an enormous technological advantage for process quality. Material quality, hygiene and compatibility As this dissolver stirrer is designed for direct, continuous contact with aggressive chemicals, highly abrasive pigments and reactive media, all parts in contact with the media (including the dissolver disc and the shaft) are made from high-quality, chemically extremely resistant AISI 316L stainless steel. This industrially proven material not only guarantees outstanding resistance to most organic solvents, acids and alkalis, but can also be cleaned safely and thoroughly after use, leaving no residue. Thanks to its robust construction, the unit is ideally suited to the rigours of everyday laboratory use. As an original accessory, the S 25 KV - 26 LR is precisely matched to IKA’s reactor platforms. It is fully compatible with the T 25 digital LR disperser, the LR 1000 systems (basic and control) and the entire LR-2.ST series (including Allrounder, High Performer and Starvisc). Investing in this highly specialised tool massively increases the efficiency of your laboratory processes, significantly reduces mixing times and decisively optimises the quality of your end products.

IKA S 25 D - 10 G - KS disposable dispersing tool (12 pieces), plastic, Ø 10 mm, 0003452200
The gold standard for contamination-free sample preparation: the IKA S 25 D - 10 G - KS disposable dispersing tool In highly specialised analytical laboratories, medical diagnostics, forensic evidence collection and modern biotechnological research, the quality of sample preparation is the crucial foundation for valid results. When grinding and homogenising tissue samples, cell cultures or infectious materials using a high-performance disperser from the IKA T 25 series, enormous mechanical shear forces are at work. These forces inevitably force microscopically small components of the sample deep into the mechanical gaps and plain bearings of the tool being used. Unless a conventional stainless-steel tool is laboriously dismantled, chemically cleaned and sterilised in an autoclave after every single sample, there is a risk of the dreaded cross-contamination (carry-over). It is precisely to address this critical, time-consuming and error-prone issue that IKA has developed the revolutionary S 25 D - 10 G - KS disposable dispersing tool (MPN 0003452200). Supplied in a cost-effective pack of 12, this tool, made from high-quality medical-grade plastic, offers uncompromising homogenisation performance whilst providing 100 per cent protection against sample carry-over. The end of cross-contamination in highly sensitive processes The fundamental concept behind the “KS” (plastic) series is the single-use principle. In fields such as PCR (polymerase chain reaction) analysis, next-generation sequencing (NGS) or toxicological testing, even a single carried-over DNA molecule or a tiny trace of an active substance from a previous sample can lead to false-positive results. At best, such misinterpretations merely ruin an expensive series of experiments; at worst, however, they can lead to incorrect medical diagnoses or forensic evidence that is inadmissible in court. With the IKA S 25 D - 10 G - KS, you can completely eliminate this risk. For each new patient or environmental sample, you remove a brand-new, unused tool from its packaging. After the dispersion process, the plastic tool is simply disposed of properly, together with the potentially contaminated residual sample. The error-prone and time-consuming cleaning and sterilisation cycle required for conventional stainless steel tools is completely eliminated, raising your process reliability (GLP/GMP) to an unprecedented level. Technological precision: 10 mm stator and coarse (G) geometry Despite being designed as a single-use item, this tool is in no way inferior to its steel counterparts in terms of homogenisation efficiency. It operates on the highly effective rotor-stator principle. The stator has a precisely dimensioned diameter of 10 millimetres (hence the ‘10’ in the product name). This compact size defines the optimal working range: the tool is precisely designed for the rapid homogenisation of small to medium sample volumes in the range of 10 to 100 millilitres (based on the viscosity of water). The abbreviation ‘G’ stands for a coarse slot geometry on the stator. This open, high-throughput design is of fundamental importance when you need to process coarse-grained, tough or highly fibrous raw materials. Plant roots, muscle tissue, cartilage or compact pharmaceutical tablets are drawn deep into the shear gap by the rotor’s powerful axial suction forces and shattered there into their finest components at speeds of up to 24,000 revolutions per minute. Cost-effectiveness and Total Cost of Ownership (TCO) in the laboratory At first glance, the ongoing purchase of disposable tools is often regarded as an additional cost factor. However, a detailed total cost of ownership (TCO) analysis in day-to-day laboratory practice consistently proves the exact opposite. The purchase cost of an IKA S 25 D single-use tool is significantly lower than the cumulative cost of the working time a highly qualified laboratory technician spends each day at the sink dismantling and brushing stainless steel tools. Added to this are the substantial savings on expensive, aggressive cleaning chemicals, the energy consumption of the autoclave, and the inevitable wear and tear on PTFE slide bearings and seals in conventional instruments. By using single-use technology, laboratories drastically increase their sample throughput. Staff are freed from tedious cleaning tasks and can once again concentrate on the actual, value-adding scientific analysis. System integration for maximum occupational safety (splash protection) The S 25 D - 10 G - KS is designed as a precisely fitting original accessory exclusively for the IKA T 25 dispersion drives (compatible with T 25 digital, T 25 easy clean digital and T 25 easy clean control). Another advantage of this system, which is absolutely crucial for occupational health and safety, is its compatibility with IKA disposable tubes (e.g. the ET50 tube). Fitting this protective tube onto the tool shaft creates a completely sealed system. When dispersing infectious bacterial cultures, toxic chemicals or extremely foul-smelling environmental samples, no dangerous splashes or invisible aerosols can escape into the laboratory environment or the fume cupboard. You therefore not only protect yourself and your staff from dangerous pathogens, but also prevent external contamination of your valuable laboratory instruments. The S 25 D - 10 G - KS is therefore the ultimate choice for laboratories that place the highest priority on uncompromising safety, maximum efficiency and absolute sample purity. Technical data Product type: Disposable dispersing tool (rotor-stator) Packaging unit (PU): 12 pieces per box Material: High-quality, dimensionally stable and chemical-resistant plastic (PC/polymer blend) Stator diameter: 10 mm Rotor diameter: approx. 6.8 mm Working range (H₂O volume): 10–100 ml Slot geometry: Coarse (G) for high throughput with viscous samples Gap between rotor and stator: 0.2 mm Maximum permissible speed: up to 24,000 rpm (depending on the drive used) Immersion depth: 15 – 85 mm Compatible drives: IKA T 25 digital, T 25 easy clean digital, T 25 easy clean control Sterilisable: No (purely a single-use item to prevent contamination) Contents 1 x box containing 12 IKA S 25 D - 10 G - KS single-use plastic dispersing tools (Important note: The required T 25 drive motor, as well as any sample vessels or protective tubes that may be needed, are available separately and are not included in this delivery.) Individual requirements & accessories To realise the full potential of this tool in terms of health and safety, we strongly recommend using it in combination with the IKA S 18/25-ET50 disposable tube, which fits seamlessly onto the shaft and acts as a hermetic aerosol barrier. Do you need to process significantly larger sample volumes (up to 500 ml)? Then simply switch to the larger version, the S 25 D - 14 G - KS (with a 14 mm stator).

IKA CT.15 Cleaning tube, replacement cleaning tubes with caps (15 pieces), for T 25, 0020006595
Maximum efficiency and purity in sample preparation: the IKA CT.15 cleaning tubes In modern analytical chemistry, strictly regulated pharmaceutical quality control and biological research, the consistent prevention of cross-contamination (carry-over) is the absolute foundation of reliable measurement results. When working with high-performance dispersers such as the tried-and-tested IKA T 25 series, tissues, powders or emulsions are broken down using extreme shear forces. Microscopically small residues of these samples inevitably remain in the narrow shear gap between the stator and rotor. To remove these contaminants safely, gently and completely after each homogenisation, IKA has established a systematic, hydrodynamic 3-stage cleaning process. The IKA CT.15 cleaning tubes (MPN 0020006595) are the essential consumable component for this highly effective system. Supplied in an extremely practical and cost-effective pack of exactly 15 pieces, these high-quality cleaning tubes enable a seamless, uninterrupted and highly standardised workflow in laboratories with high sample throughput. The perfect complement to the TS 25-3 cleaning system The CT.15 set is the ideal, logical extension for all users who already utilise the IKA TS 25-3 Cleaning Tool (the robust tube holder) in their laboratory. The validatable cleaning process recommended by IKA consists of three consecutive phases: intensive pre-cleaning with a strong, sample-specific solvent; main cleaning with a suitable laboratory cleaning agent (surfactant); and final cleaning and rinsing with demineralised water. By purchasing this pack of 15, you can easily set up several of these 3-stage stations in parallel and keep them permanently stocked. Whilst one member of staff is still dispersing samples at Station A, freshly filled tubes are already ready for immediate cleaning at Station B. This forward-planning approach eliminates tedious waiting times at the laboratory sink, speeds up the entire analysis cycle enormously and relieves the burden on highly qualified laboratory staff in their daily routine tasks. Health and safety through tightly sealing caps A major, often underestimated problem with the manual cleaning of dispersion tools in open beakers is occupational health and safety. The extremely high speeds of the drive motor inevitably generate fine aerosols and uncontrolled splashes during cleaning and dispersion. If the solvents used are volatile, irritant or toxic chemicals, this poses a significant health risk through inhalation or skin contact. Every single tube in the IKA CT.15 set is therefore supplied as standard with a precisely fitting, tight-sealing cap. These caps transform the cleaning process into a closed, absolutely safe system in no time at all. Simply pierce the prepared opening with the shaft of the dispersing tool, and the spillage of hazardous substances into the laboratory environment or the fume cupboard is effectively and reliably prevented. This not only protects the health of your staff, but also safeguards expensive laboratory equipment and sensitive instruments in the immediate vicinity from aggressive chemical vapours. Consistently prevent cross-contamination with dedicated tubes Another enormous analytical advantage of this 15-piece set is the ability to clearly physically separate work processes. Even with the most thorough rinsing, plastic vessels can, over time, suffer microscopic scratches on their inner walls due to the high shear forces of the disperser or detached hard particles. Stubborn biofilms, denatured proteins or chemical residues can become trapped in these fine scratches. With a generous supply of 15 tubes, you can immediately and properly replace heavily worn vessels. Even more important for GLP compliance: you can designate specific tubes for particular solvents or certain types of samples (e.g. ‘For RNA extraction only’ or ‘For high-fat samples only’). This strict, physical separation categorically rules out the possibility of the cleaning solvent itself becoming an invisible source of contamination for the next sample. Unrestricted system compatibility and TCO optimisation The IKA CT.15 cleaning tubes are 100 per cent compatible with IKA’s globally established T 25 ecosystem. They are fully compatible with the high-performance dispersing drives of the T 25 digital series, as well as the state-of-the-art T 25 easy clean digital and T 25 easy clean control ranges. Whether you use classic S 25 N standard tools, the S 25 KR series or the vacuum-tight KD tools – the geometry of the tubes is designed so that the tool rotates at the ideal distance from the base, achieving a perfect hydrodynamic cleaning effect without damaging the vessel. This consistent and gentle care also prevents premature wear of the sensitive plain bearings in the tools. A dispersing tool that is not manually scrubbed with hard brushes retains its precise gap geometry for significantly longer, which in turn guarantees consistent, highly reproducible particle sizes in your subsequent samples and drastically reduces your Total Cost of Ownership (TCO) for spare parts. With a total weight of just 0.3772 kg per packaging unit, the tubes are also ideal for storage and keeping on hand at the workplace. Technical data Packaging unit: 15 pieces per pack Compatible drive motors: IKA T 25 digital, T 25 easy clean digital, T 25 easy clean control Intended use: Consumables for the 3-stage cleaning process (solvent, cleaning agent, demineralised water) Health and safety benefit: Includes caps to prevent hazardous aerosols and solvent splashes Weight (per pack): 0.3772 kg Material: High-quality, chemical-resistant plastic Contents 15 x IKA CT.15 cleaning tubes 15 x Tight-fitting caps as splash guards (Please note: The sturdy tube holder (TS 25-3), as well as the dispersing drive and the dispersing tool, are not included in the scope of delivery!) Individual requirements & accessories If you are setting up this system in your laboratory for the first time, you will definitely need the complete IKA TS 25-3 Cleaning Tool (which includes the tube holder) to ensure a secure, wobble-free stand. This pack of 15 is the perfect addition for replacing worn-out tubes or speeding up your workflow by running multiple cleaning stations in parallel. If you have any questions about establishing SOPs for tool cleaning, please feel free to contact our procurement service. We will provide you with comprehensive advice on optimising your processes.
IKA S 10 N - 10 G dispersing tool, Ø 10 mm, 0003370100
The IKA S 10 N – 10 G dispersing tool is a specialised, materials-science-optimised system component designed for precise rotor-stator dispersion in the 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 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 laboratory vessels, the precise fluid-dynamic geometry of this tool prevents thermal stress on samples and ensures complete homogenisation. For laboratory managers and procurement officers in industrial research facilities, this tool offers the highest level 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 of 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 10 G generator is characterised by an optimised tooth geometry, which enables rapid primary fragmentation of fibrous, tough or cellular sample structures across an extended volume range. 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 a robust PTFE bearing. 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 instrument’s unrestricted sterilisability: the entire dispersing instrument 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 10 millimetres and a shaft length of 115 millimetres, enabling reliable operation in various reaction vessels and laboratory glassware. The working range covers a sample volume of 1 to 100 millilitres, allowing flexible sample series to be processed efficiently whilst minimising material wastage. Thanks to the shaft’s easy disassembly, the tool can be cleaned quickly and thoroughly after use, significantly speeding up the laboratory’s workflow and minimising downtime.

IKA S 18 D - 10 G - KS disposable dispersing tool (12 pieces), plastic, Ø 10 mm, 0003452400
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. Technical data Model: S 18 D - 10 G - KS Product type: Disposable dispersing tool (rotor-stator) Packaging unit (PU): 12 pieces per pack Material: High-quality, dimensionally stable plastic (KS) Stator diameter: 10 mm Rotor diameter: 6.8 mm Working range (H₂O volume): 10 – 100 ml Slot geometry: Coarse (G) Gap between rotor and stator: 0.2 mm Maximum permissible speed: 24,000 rpm Immersion depth: 15 – 85 mm Max. permissible operating temperature: 100 °C Compatible drives: IKA T 18 digital, T 18 basic Sterilisable: No (Designed as a single-use item only to prevent contamination) Contents 1 x pack of 12 IKA S 18 D - 10 G - KS plastic dispersing tools (Note: The T 18 drive motor and any sample vessels or protective tubes that may be required are not included in the scope of delivery!) Individual requirements & accessories To realise the full potential of this closed safety system, we strongly recommend combining it with the IKA S 18/25-ET50 disposable tube as an effective splash guard. If you need to process sample volumes of less than 10 ml, IKA also offers smaller disposable tools with a 7 mm stator diameter.

Continuous workflow: The wrapping of the shaft by tendons, plant fibres or polymer strands is effectively prevented. You can digest your samples in a fraction of the time, often without having to laboriously chop them up with a scalpel beforehand. The happy medium (“10 G”) With a stator diameter of 10 mm, this tool bridges the gap between micro-attachments and large standard tools. Volume range: It homogenises volumes from 1 ml to 100 ml (H₂O). This makes it the perfect all-rounder for centrifuge tubes (e.g. 15 ml or 50 ml Falcon tubes) and small beakers. Coarse (“G”): The slot width ensures high throughput and rapid primary comminution. With speeds of up to 25,000 rpm, you can still achieve very fine particle sizes. High-quality materials (“N”) The tool features a chemically highly resistant PTFE bearing (“N”). Easy to clean: After use, the dispersing tool can be dismantled into its individual parts in just a few simple steps for manual cleaning or sterilisation. Hygienic: All components in contact with the medium are made of high-quality stainless steel (AISI 316L) and PTFE. It is fully autoclavable at 121 °C. Areas of application Life sciences: Digestion of muscle tissue, skin or plant material for nucleic acid extraction. Food inspection: Homogenisation of fibrous meat or tough vegetables.
