IKA MINISTAR 80 control overhead stirrer, up to 50 l, 80 Ncm, 0025001990

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 With viscous batches this matters, because material on the wall is withdrawn from the mixing process.It is used at low speeds.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. In our range 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 offer 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 301 stirrer shaft guard (MPN 0002603000) is an essential mechanical safety component for the safe and accident-free operation of laboratory overhead stirrers. During intensive mixing, dispersing or homogenisation processes, considerable kinetic forces act on rotating stirrer shafts. This professional shaft guard forms a physical barrier that reliably protects laboratory staff from accidental contact with the rotating parts. It effectively prevents clothing, hair or laboratory gloves from being drawn in, making the safety device a key component in risk assessments and in implementing national and international health and safety requirements. Stepless length adjustment for flexible experimental set-ups From a process engineering perspective, the R 301 model excels thanks to its high degree of telescopic flexibility. The guard can be adjusted steplessly along its axis within a length range of 190 to 310 mm and locked into place precisely. This variable geometry allows for precise adaptation to different shaft lengths, vessel heights and varying immersion depths of the stirring elements. Laboratories thus benefit from a highly adaptable protective system that can be flexibly integrated into changing experimental set-ups without compromising workplace ergonomics. Unrestricted process control thanks to a high-quality Plexiglas matrix The cylindrical protective screen is made entirely from a high-purity, mechanically stable Plexiglas matrix. This material combines minimal weight with outstanding optical clarity. Laboratory staff are able to monitor the mixture, transient flow patterns, phase transitions or any delayed boiling in the sample vessel at all times without restrictions. At the same time, the Plexiglas structure offers effective protection against transient media splashes and can be cleaned quickly and without leaving any residue.
