The heating element in the Bandelin SONOREX DIGITEC DT 31 H operates at a fixed temperature of 65 °C. This model does not have an adjustable temperature range. The inner dimensions of the tank are 190 x 85 x 60 mm and it has a capacity of 0.9 l.70-watt heating element with fixed temperatureThe heating power is 70 watts, and the bath temperature is set at 65 °C. A dry-run protection feature safeguards the heating element. If you wish to select the bath temperature yourself between 20 and 80 °C, the DT 52 H is a better choice; however, its tank is larger at 1.8 l. The DT 31 is available without a heater, but with otherwise identical dimensions.Ultrasonic and timerA vibration system delivers a peak power of 160 watts at 35 kHz (rated power 40 watts). SweepTec automatically distributes the sound field, and there is also a pulse function. This model does not feature DEGAS degassing. The cleaning duration can be set to 1, 2, 3, 4, 5, 10, 15 or 30 minutes (± 5 %), or the bath can run continuously. The unit switches off automatically after 12 hours without any button presses.Dimensions and materialsThe unit measures 205 x 100 x 180 mm externally and weighs 2.4 kg. The tank (0.8 mm) and housing are made of 1.4301 stainless steel; the tank has a fill-level mark for a working capacity of 0.6 l. There are no handles or drain; the mains cable is 2 m long and permanently fitted. The current consumption is 0.5 A at 230 V; the protection rating is IP 33.AccessoriesCompatible accessories include the K 08 insert basket (170 x 65 x 50 mm, up to 1 kg), the lid D 08, the perforated lid DE 08 for two insert beakers, and insert beakers with a rubber ring made of glass (0.4 l SD 04, 0.6 l SD 05) or polypropylene (0.4 l KB 04).

Sensor tips, small cannulas, jewellery or individual cuvettes do not require a large bath for ultrasonic cleaning; rather, they need a bath that delivers uniform cavitation to every corner of the tank. With a total capacity of 0.9 l, the Bandelin SONOREX SUPER RK 31 is the smallest model in the SUPER RK series and is designed specifically for these small-item cleaning tasks in laboratories, medical practices and workshops.Small tank, noticeable cavitationAt an operating frequency of 35 kHz, the RK 31 generates a peak ultrasonic power of 160 watts at a nominal ultrasonic power of 40 watts, distributed across a single vibration system. This is sufficient for the small tank volume of 0.9 l (working capacity 0.6 l); larger SUPER RK models, such as the RK 514 BH, on the other hand, operate with four vibration systems covering a significantly larger area. The automatic SweepTec function continuously adjusts the frequency slightly, thereby preventing standing waves in the ultrasonic field; as a result, the cleaning effect remains uniform even in small volumes.Thin stainless steel tank for the laboratory benchThe oscillating tank is made of 1.4301 stainless steel with a thickness of 0.8 millimetres; the housing is made from the same material. The internal dimensions of 190 x 85 x 60 mm and the compact external dimensions of 205 x 100 x 180 mm ensure that the unit, with a net weight of 2.2 kg, can still be accommodated even on already occupied work surfaces. The RK 31 is operated via a robust rotary handle; the timer ranges from 1 to 15 minutes (tolerance ± 5 %), and continuous operation is also available.No drain, no heating, but simpleThis model has no drain; a ball valve is not provided for this size. With a capacity of 0.9 l, the tank can be emptied directly over the edge after the cleaning cycle; an additional connection would be rather cumbersome in this case. Similarly, the RK 31 does not feature a heating element. Anyone requiring heating for cleaning in the same size should choose the RK 31 H with a fixed 65 °C; the next larger model with adjustable heating is the RK 100 H.Selection guide for the SUPER RK seriesThe SUPER RK series from Bandelin covers a wide range: from the RK 31 with a 0.9-litre capacity to the RK 1050 with a total capacity of 58 l. If you are only cleaning individual small parts, sensor tips or cuvettes, you are properly equipped with the RK 31. If the batch size increases to include several instruments or small glass vessels, it is worth considering the RK 100 H (3.0 l, heated) or the RK 103 H (4.0 l, heated and with a drain). For entire sieves or beakers, the larger models from the RK 510 (9.7 l) upwards are the more suitable choice.SUPER RK, DIGITEC DT and smart ST comparedIn addition to the SUPER RK series with classic rotary knob control, Bandelin offers the DIGITEC DT series with push-button control, an LED display and DEGAS degassing, as well as the smart ST series with a touchscreen, finely adjustable power control and programme memory. Those who only clean occasionally and value straightforward, robust operation would be well advised to choose a SUPER RK model such as the RK 31. We also offer Elma Elmasonic ultrasonic baths, an alternative for laboratories already equipped with this brand.Use and maintenanceThe working capacity of 0.6 l is deliberately set below the total capacity of 0.9 l, as space must be left for the items being cleaned when filling the bath; otherwise, the liquid will spill over the rim. As for the cleaning solution itself, Bandelin offers its own TICKOPUR range of concentrates; for the SONOREX PR series of pipette cleaners, this is included in the set, whilst a suitable concentrate for the RK 31 must be purchased separately. Freshly prepared cleaning fluid contains dissolved air, which initially dampens cavitation; a short pre-run in continuous operation before the actual cleaning process dispels it. The stainless steel tank is compatible with most aqueous cleaning agents; however, abrasive sponges or chlorine-based agents should still be avoided. At the end of the working day, it is best to empty and dry the tank.Typical applicationsCleaning of small sensor tips, cannulas and needlesPrecision cleaning of jewellery and small metal partsPre-cleaning of precision mechanical components and watch movementsCleaning individual cuvettes or small sample vessels in the laboratoryFrequently asked questionsIs the SONOREX SUPER RK 31 heated?No, the RK 31 is unheated. The heated version with the same volume is the RK 31 H (fixed at 65 °C); the next larger model with adjustable heating is the RK 100 H.Does the unit have a drain?No, the RK 31 has no ball valve; with a capacity of 0.9 l, the bath is emptied directly.Is the RK 31 a medical device?Yes, it is classified as a Class I medical device according to Regulation (EU) 2017/745 and is also CE-compliant with the Low Voltage, EMC and RoHS Directives.Are the basket and lid included in the scope of delivery?No, the K 08 insert basket and the D 08 lid are available separately as accessories.Technical detailsTotal capacity / Working capacity0.9 l / 0.6 lInternal dimensions of tank (L x W x D)190 x 85 x 60 mmExternal dimensions (L x W x H)205 x 100 x 180 mmWeight (net)2.2 kgUltrasonic frequency35 kHzUltrasonic powerPeak ultrasonic power 160 W, nominal ultrasonic power 40 W, 1 vibration systemTimer1 to 15 minutes (± 5 %) or continuous operationOperationRotary knobFunctionsSweepTec, pulse functionTank materialStainless steel 1.4301, thickness 0.8 mmHousing materialStainless steel 1.4301DrainNo drain/ball valveMains connection230 V~ (± 10 %), 50/60 Hz, optionally 115 V~, 2 m fixed mains lead, protection class ICurrent consumption230 V 0.2 A / 115 V 0.4 AProtection ratingIP 32Medical device classClass I (Regulation (EU) 2017/745)ConformityLow Voltage Directive 2014/35/EU, EMC Directive 2014/30/EU, RoHS Directive 2011/65/EUPackaging dimensions320 x 235 x 205 mmScope of delivery1x Bandelin SONOREX SUPER RK 31 ultrasonic bathFixed mains lead (2 m)Instructions for useThe insert basket and lid are not included in the scope of delivery and are available separately.Individual requirements and procurement serviceFor the K 08 insert basket, the D 08 lid or a larger SUPER RK model, there is an individual procurement requirement.
