IKA R 50 High-speed Stirring Shaft, Dissolver Disc, for T 50 digital, 0001689300

If a process in a beaker reaches its limits because 2 litres suddenly need to become 20, a drive with more power and a longer arm is required – but without having to switch to a completely different system. The T 50 digital ULTRA-TURRAX covers precisely this transition, from 0.25 to 30 litres (H₂O), with a speed range of 600 to 10,000 revolutions per minute. As with the smaller model, this is a drive unit only, without a dispersing tool.Constant speed even with varying viscosityThe electronic speed control maintains the set value even if the viscosity changes during the batch, with a maximum permissible viscosity of 5,000 mPas. A soft start reduces the start-up load, whilst electronic overload protection and an error code display ensure reliable operation. Without an attachment fitted, the noise level is 72 dB(A); the speed itself is displayed via an LED and can be adjusted continuously.Powerful drive for larger volumesWith a power input of 1,100 watts and an output of 700 watts, the T 50 digital significantly outperforms the smaller T 25 digital; the extension arm measures 16 millimetres in diameter and 220 millimetres in length. Measuring 115 x 355 x 139 millimetres and weighing 5.85 kilograms, the machine can still be guided by hand. It operates on 220 to 240 volts at 50 or 60 hertz; a voltage variant of 100 to 120 volts is also available. It has an IP 20 protection rating in accordance with DIN EN 60529, and is suitable for ambient temperatures of 5 to 40 degrees Celsius with up to 80 per cent relative humidity.Tool change using the supplied wrenchesA socket wrench for changing the shaft and another for changing the dispersing tool are supplied with the drive unit; the dispersing tool itself is not included and must be selected to suit the application. The range includes, amongst others, the stainless steel tools S 50 N – G 45 G (Ident 0008003000) and S 50 N - G 45 F (ID 0008003900); the R 1405 propeller (ID 0001289800) for axial flow; and the R 1402 dissolver (ID 0001243300) for radial flow. The S 50 N – W 80 SMK jet mixing head (ID 0008006300) is also suitable for dispersion tasks requiring high shear. For stationary operation, the H-stand R 2722 (ID 0001412000) with cross-sleeve R 271 (ID 0002664000) is available.Typical applicationsScale-up of laboratory formulations to pilot plant volumesHomogenisation of suspensions and emulsions up to 30 litresPilot trials prior to scaling up to production scaleInterchangeable rotor-stator assemblies depending on the applicationSelection guide: smaller, larger or as a complete setThose working at a laboratory scale of up to 2 litres are better served by the more compact T 25 digital ULTRA-TURRAX drive unit or the T 25 digital Solution complete set; for even smaller batches, the T 18 brushless digital is suitable. If requirements exceed 30 litres, or if a three-phase connection is available anyway, the T 65 digital ULTRA-TURRAX can handle volumes of up to 50 litres.Technical detailsMotor power input / output1,100 W / 700 WProcessable volume (H₂O)0.25 to 30 lMax. viscosity5,000 mPasSpeed range600 to 10,000 rpm, continuously variable (1 per cent deviation)Speed displayLEDNoise level (without tools)72 dB(A)Boom diameter / boom length16 mm / 220 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, 1,100 W (additional voltage variant 100 to 120 V available)Dimensions (W x H x D)115 x 355 x 139 mmWeight5.85 kgContentsT 50 digital ULTRA-TURRAX drive unitSocket wrench for changing the shaftSocket wrench for tool changeA dispersing tool is not included and must be selected separately to suit the specific application.Regulatory informationThis unit is an electrical appliance within the meaning of the German Electrical and Electronic Equipment Act (ElektroG). The WEEE registration number of the manufacturer, IKA, is DE 66784213. Information on the return of end-of-life equipment can be found on our Environment and Disposal page.Warranty and procurement serviceThe IKA manufacturer’s warranty applies to the T 50 digital: 2 years, extended to 3 years upon registration at ika.com/register within 90 days of purchase. LT Laborhandel’s procurement service assembles dispersing tools, stirring elements and stands to suit the existing drive; on request, it also provides factory calibration certificates and qualification documents for regulated areas.
