IKA S 25 KD, 25 G Dispersing Tool, Ø 25 mm, Ball Bearings, for T 25, 0020002972

A batch of formulation in a beaker, an emulsion in a 500-millilitre flask, a batch of cell suspension for sample preparation: the T 25 digital ULTRA-TURRAX is the classic drive unit for all tasks in everyday laboratory work involving volumes between 1 millilitre and 2 litres. It covers a speed range from 3,000 to 25,000 revolutions per minute and is supplied as a drive unit only, without a dispersing tool, so that each laboratory can choose the appropriate tool geometry itself.Electronic speed control for reproducible batchesThe speed can be adjusted continuously between 3,000 and 25,000 rpm, with a deviation of just 1 per cent. An LED display shows the set value directly, whilst electronic overload protection and an error code display ensure reliable operation. Without an attachment fitted, the unit remains comparatively quiet at 75 dB(A); the maximum viscosity is 5,000 mPas. For batches that alternate between low- and medium-viscosity phases, the speed can be readjusted at any time during the process without switching off the unit.Compact drive for the laboratory benchMeasuring 87 x 271 x 106 millimetres and weighing 2.5 kilograms, the T 25 digital takes up little bench space; the arm measures 13 millimetres in diameter and 160 millimetres in length. The power input is 800 watts, whilst the power output is 500 watts. The unit operates at 220 to 240 volts at 50 or 60 hertz; a voltage variant of 100 to 120 volts is also available. Protection class IP 20 in accordance with DIN EN 60529 and a permissible duty cycle of 100 per cent round off the key technical specifications; the permissible ambient temperature range is from 5 to 40 degrees Celsius with up to 80 per cent relative humidity.Assemble tools and stand as requiredAs no dispersing tool is supplied, each laboratory selects the geometry to suit the application: reusable stainless steel tools such as the S 25 N - 18 G - ST (Ident 0004447300) or the S 25 N - 25 G (Ident 0001713300), as well as disposable plastic tools in two sizes for applications where cross-contamination between samples must be ruled out. The S 25 KV – 25 G dissolver tool (Ident 0002466900) is suitable for more viscous media. For stationary operation, the R 1826 plate stand (ID 0003160100) with R 182 cross-sleeve (ID 0002657700) is available; for cleaning, the TS 25-3 Cleaning Tool (ID 0020003013) or the disposable tube S 18/25-ET50 (ID 0003452500) are suitable for cleaning.Typical applicationsHomogenisation of wastewater samples in environmental analysisDispersion tasks in laboratory reactorsWork under vacuum or pressure with suitable accessoriesSample preparation in medical researchSelection guide: individual drive unit or complete setIf you do not wish to put together the tool and stand separately, you will find the same technology, including accessories, in the T 25 digital Solution. For smaller tasks involving temperature measurement, the T 25 mini control ULTRA-TURRAX is the more compact alternative; for a housing design that is easier to clean, the T 25 easy clean digital is the choice. If the volume range of up to 2 litres is no longer sufficient for larger batches, the T 50 digital ULTRA-TURRAX handles volumes of up to 30 litres.Technical detailsMotor power input / output800 W / 500 WProcessing volume (H₂O)0.001 to 2 lMax. viscosity5,000 mPasSpeed range3,000 to 25,000 rpm, continuously variable (1 per cent deviation)Speed displayLEDNoise level (without tools)75 dB(A)Boom diameter / boom length13 mm / 160 mmProcess typebatchPermissible duty cycle100%Permissible ambient temperature range / humidity5 to 40 °C / 80 % (up to 31 °C), decreasing linearly to 50 % at 40 °CProtection classIP 20 in accordance with DIN EN 60529Rated power220 to 240 V, 50/60 Hz, 800 W (additional voltage variant 100 to 120 V available)Dimensions (W x H x D)87 x 271 x 106 mmWeight2.5 kgContentsT 25 digital ULTRA-TURRAX drive unitA dispersing tool is not included and must be selected separately to suit the specific application.Regulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).

The T 25 easy clean digital ULTRA-TURRAX is the drive unit in the IKA T 25 easy clean series, designed for laboratories that need to clean quickly and thoroughly between batches. The tool can be opened for cleaning without having to completely dismantle the rotor-stator unit, which saves time when changing products frequently and prevents cross-contamination. A dispersing tool is not included with the unit; it is selected separately to suit the specific application.The easy-clean principle in practiceTools in the easy-clean series are identified by the abbreviation ‘EC’ in their name and can be opened for cleaning without the need to dismantle the entire drive unit. This saves users the time-consuming process of changing tools and completely dismantling the unit when, for example, they are processing a cosmetic emulsion in the morning and a different formulation in the afternoon. A brushless DC motor drives the tool, which reduces carbon dust in the cleanroom and keeps operation comparatively quiet at 70 dB(A) when no tool is fitted.Display, timer and operationThe speed is shown on an LED display and can be adjusted continuously between 3,000 and 25,000 revolutions per minute with a tolerance of 2 per cent. A built-in timer with its own LED display manages recurring process times, meaning a batch does not need to be stopped manually. A micro-USB interface is provided for connection to labworldsoft, via which parameters can be documented.Performance data and mechanical designWith a power consumption of 500 watts and an output power of 400 watts, the unit processes volumes of 1 to 2,000 millilitres of water and media with a viscosity of up to 5,000 mPas. The arm measures 13 millimetres in diameter and 160 millimetres in length; the housing is protected against dust and coarse foreign particles to IP 30 in accordance with DIN EN 60529 and is designed for a 100 per cent duty cycle. The unit operates on a mains supply of 220 to 240 volts; for locations outside the European mains supply, a 100 to 120-volt version is available on request.Documentation and ConformityThe unit comes with its own EU Declaration of Conformity available for download, as well as a data sheet in PDF format. The operating instructions cover not only this drive unit but also the ‘control’ variant of the T-25 easy-clean series and are available in 14 languages, ranging from German and English to Chinese, Thai and Korean. This means that the same set of instructions can be used at multiple workstations in locations with an international workforce.Typical applicationsThe wide speed range and the ‘easy-clean’ cleaning system make the unit particularly attractive in situations where there are frequent changes between different samples.Homogenisation of medical and pharmaceutical samples with frequent product changesEmulsification of cosmetic formulations on a laboratory scaleSuspending paints and coatingsDispersing under vacuum or pressure in conjunction with an IKA laboratory reactorSelection guide: digital or control, single unit or set?If you do not require temperature measurement, this digital drive unit is a good choice. If the sample temperature needs to be monitored during dispersion – for example, with heat-sensitive formulations – the T 25 easy clean control ULTRA-TURRAX is a better option; it measures temperatures between 0 and 125 degrees Celsius via an RFID-enabled tool. If you do not yet own a dispersing tool, the T 25 easy clean digital Solution saves you the trouble of selecting a separate tool; the set comes complete with the tool, stand and cross-coupling. For more compact applications with Wi-Fi connectivity and smaller volumes, the T 25 mini control ULTRA-TURRAX is also available; for larger volumes requiring higher performance, the T 25 digital ULTRA-TURRAX is the ideal choice.Technical detailsThe following table summarises the key specifications for the drive, operation and connections, as specified by IKA for the digital version of the T 25 easy clean series.Motor power input / output500 W / 400 WProcessable volume (H₂O)1 to 2,000 mlMax. viscosity5,000 mPasSpeed range3,000 to 25,000 rpm, continuously variable (2% deviation)Speed displayLEDMotor typebrushless, direct currentNoise level without tools70 dB(A)Boom diameter / boom length13 mm / 160 mmTimerYes, LED displayPermissible duty cycle100 %Permissible ambient temperature / humidity5 to 40 °C / 80 %Protection classIP 30 in accordance with DIN EN 60529USB interfaceMicro-USBPower rating220 to 240 V, 50/60 Hz, 500 W (alternative voltage option: 100 to 120 V)Dimensions (W x H x D)89 x 270 x 161 mmWeight3 kgContentsT 25 easy clean digital ULTRA-TURRAX drive unitUSB cable, USB A to Micro-B, 2 mA dispersing tool is not included in the scope of delivery and must be selected separately to suit the application.Regulatory informationThis device is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG).
