IKA S 18 N - 19 G Dispersing tool, coarse, PTFE bearings, 10 to 1,500 ml, L004640

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 LT Laborhandel 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.

The complete T 18 digital Solution Set is ideal for getting started straight away without having to order a separate tool; those looking for a more compact and quieter workstation will find the T 18 mini digital Solution to be the perfect alternative with lower 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 LT Laborhandel 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, LT Laborhandel supplies 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, LT Laborhandel can assist you with procurement and configuration. Frequently Asked Questions Is a dispersing tool included in the scope of delivery?No, the T 18 digital is supplied exclusively as a drive unit. A suitable tool, such as the S 18 N - 19 G, must be purchased separately. Which tool is suitable for coarse pre-grinding?For coarse applications and tougher media, the S 18 N - 19 G with PTFE bearings is the standard choice; finer end products can be achieved with the S 18 N - 10 G. How accurately can the speed be reproduced?The LED display shows the set value within a range of 3,000 to 25,000 rpm with a deviation of around 1 per cent, which facilitates the exact repetition of test series. Is a stand included in the scope of delivery?No; for continuous operation, we recommend a separately available stand such as the R 1826 plate stand. What is the difference between the T 18 digital and the T 18 mini digital Solution?The T 18 mini digital Solution features a more compact, brushless drive with lower motor power and comes as a set including the tool and stand; the T 18 digital described here is the more powerful drive unit without accessories.
