Product information "IKA EUROSTAR 20 digital Overhead Stirrer, up to 25 l, 40 Ncm, 0020105154"
Twenty-five litres of water at a torque of 40 Ncm characterise the lowest power setting of IKA’s current EUROSTAR digital generation. According to the manufacturer, the compact housing requires up to 23 per cent less floor space than its predecessors, whilst the LCD display shows speed, the timer and a torque trend simultaneously. For standard laboratories that regularly stir small to medium-sized batches and require cleanroom compatibility, the EUROSTAR 20 digital is the entry-level model in the range. The electronics are microprocessor-controlled and maintain the set speed even if the viscosity of the sample changes during the stirring process.
Mechanics and tool change
The brushless DC motor draws 70 watts and delivers up to 22 watts to the stirring shaft, with a duty cycle of 100 per cent in continuous operation. The speed ranges from 30 to 2,000 revolutions per minute; the maximum torque of 40 Ncm decreases linearly to 20 Ncm at higher speeds. This performance is therefore sufficient for samples up to 10,000 mPas. The Quick Sense Keyless Chuck replaces the traditional chuck key; stirring shafts from 0.5 to 10 mm can be changed with one hand. The hollow shaft, with an internal diameter of 11 mm, can be inserted whilst the unit is stationary, which is practical for stirring elements that are inserted from above.
Cleanroom-compatible and protected
With a noise level of 52 dB(A) without a stirring tool, the EUROSTAR 20 digital achieves ISO cleanroom class 7 at 900 rpm and class 8 at 1,800 rpm, which is relevant for pharmaceutical, biotech and electronics laboratories. The housing, made of coated cast aluminium and thermoplastic, is chemical-resistant and protected against dust and splashing water in accordance with IP 54. A lock button prevents accidental adjustment during cleaning; the unit switches off automatically if the stirring tool becomes blocked or when the torque limit is reached. USB-C and RS232 interfaces connect the stirrer to IKA’s labworldsoft, the measurement and control software that allows speed and time profiles to be documented.
Typical applications
- Homogenisation of small to medium batches up to 25 l
- Stirring of low- to medium-viscosity samples in Class 7 or 8 cleanrooms
- Mixing tasks in research and development with documented speed curves
- Routine laboratory work involving frequent tool changes without the need for a chuck key
Selection guide: the EUROSTAR series at a glance
Six EUROSTAR models make up IKA’s current range: ‘digital’ versions with LCD or LED displays, and ‘control’ versions with a detachable WiCo controller, TFT display and PT1000 temperature measurement. The model number gives an approximate indication of the performance class; the decisive factors are stirring capacity, torque and viscosity limit.

The IKA R 1330 anchor stirrer (MPN 0002022300) is a stirring element made of stainless steel 1.4571 for overhead stirrers. It has a stirrer diameter of 45 mm and a shaft with a diameter of 8 mm and a length of 350 mm. It is intended for medium to highly viscous media that are stirred at low speeds, up to a maximum of 1,000 rpm.A polymer batch that sits thick in the vessel, or a mixture with a high mineral content that is to stay evenly distributed: the R 1330 is intended for tasks like these.Tangential flow of the anchor stirrer with a high shear rate at the edgeThe anchor stirrer moves the medium tangentially, that is, in the circumferential direction around the stirrer axis, and not axially like a propeller stirrer. The shear rate is high at the edge of the stirrer, and few deposits are left on the vessel wall. With viscous batches this matters, because material on the wall is withdrawn from the mixing process.It is used at low speeds. The stirrer diameter of 45 mm determines the minimum width of the opening of the stirring vessel.Typical applicationsHomogenising medium to highly viscous liquids in the laboratoryStirring in polymer reactionsEvenly distributing high mineral content in liquidsBatches where little material should be deposited on the vessel wallWorking at low speeds on an overhead stirrerSuitable for IKA overhead stirrers with an 8 mm chuckThe shaft with a diameter of 8 mm fits into chucks for an 8 mm shaft. These include the IKA overhead stirrers EUROSTAR 20, 40, 60, 100, 200 and 400 (digital and control), RW 20 digital as well as MINISTAR, MICROSTAR and NANOSTAR. At LT Laborhandel you will find EUROSTAR 20, 40, 60, 100, 200 and 400 digital, RW 20 digital, MINISTAR 20, 40 and 80 digital, MICROSTAR 7.5 digital and NANOSTAR 7.5 digital.Whether a stirrer drives the anchor stirrer safely in your medium depends on the viscosity and on the torque of the stirrer. The more viscous the batch, the more torque is required. Therefore check before purchase whether your device is sufficient for your batch and whether the chuck accepts a shaft of 8 mm.MaterialThe wetted parts of the R 1330 are made of stainless steel 1.4571. The weight of the stirrer is 0.151 kg.Technical detailsTypeAnchor stirrerStirrer diameter45 mmShaft diameter8 mmShaft length350 mmMaximum speed1,000 rpmFlowtangentialSuitable formedium to highly viscous mediaMaterial, wetted partsStainless steel 1.4571Weight0.151 kgMountChuck for 8 mm shaftScope of delivery1 x IKA R 1330 anchor stirrer (MPN 0002022300). The overhead stirrer is not included in the scope of delivery.Individual requirements and procurement serviceIf your medium requires a different flow pattern, we carry the IKA R 1342 propeller stirrer for the RW 20 digital, for low to medium viscosity liquids. A stirrer shaft protector, for example the IKA R 401, also fits the overhead stirrer setup. Our procurement service helps with the choice of the suitable stirring element and the overhead stirrer for your batch.
The IKA R 401 stirring shaft guard with hinge (MPN 0020122349) is an essential mechanical safety component for the safe and accident-free operation of overhead stirrers in the laboratory. During intensive mixing and homogenisation of viscous media, high kinetic forces act on the rotating stirring shafts. This professional shaft guard reliably protects laboratory staff from accidental contact with the rotating parts, effectively preventing clothing, hair or gloves from being drawn in. The guard is therefore a fundamental element in risk assessments and compliance with strict health and safety and accident prevention regulations (UVV). Ergonomic access thanks to an integrated hinge mechanism The design highlight of the R 401 model is its integrated, smooth-running hinge system. Unlike rigid protective covers, this hinged system architecture allows quick, unobstructed access to the drill chuck and the stirrer tool in use. Laboratory staff can carry out tool changes, adjustments to the immersion depth or cleaning tasks in a way that protects the material, without the need for time-consuming dismantling of the entire guard. This ensures a smooth workflow with high time efficiency in daily multi-user operation. Material stability and unrestricted process visibility The protective screen is made from a highly transparent, impact-resistant and specialised plastic material. This choice of material guarantees uncompromising chemical resistance to transient splashes of acids, alkalis or organic solvents. The material’s excellent optical clarity ensures that visual monitoring of the stirring process, transient flow patterns or any delays in boiling within the sample vessel remains completely unrestricted and error-free at all times.
