IKA MIXSTER SET 3, modular magnetic stirrer set, 0020027389

The IKA MIXSTER SET 3 0020027389, a highly efficient, modular magnetic stirring system, represents the state of the art for parallel sample preparation in pharmaceutical research and academic education. The distinctive feature of this set, which consists of three separate stirring units, lies in its high flexibility: each unit can be operated independently or expanded via digital daisy-chaining to form a synchronously operating multi-station system with up to 30 stirring stations. For laboratory managers and procurement officers, this modular architecture offers investment security. Instead of investing in rigid multi-station stirrers, which often have to be sent off for complete repair if a single station fails, the MIXSTER system provides a redundant solution in which individual modules can be added at any time or used separately in different fume hoods.

Fluid-mechanical excellence and kinetic shear stability

In practical laboratory use, the IKA MIXSTER SET 3 0020027389 impresses with an exceptional speed range of up to 3,000 rpm. From a fluid dynamics perspective, this high rotational frequency enables the induction of extremely high Reynolds numbers even in small volumes, leading to highly efficient mixing and rapid homogenisation of concentration gradients. Power transmission is based on high-energy neodymium magnets, which ensure excellent coupling to the stir bar. This is particularly critical when working with viscous media or when incorporating solids, as the microprocessor-controlled load monitoring physically minimises the risk of the magnetic contact being lost (spin-out). The integrated soft-start function also protects the integrity of your sample liquid by preventing cavitation and uncontrolled splashing during the start-up process, a key safety consideration when handling expensive active pharmaceutical ingredients.

Material robustness and IP 66 protection rating

A crucial factor for longevity in industrial research and student teaching is the chemical and mechanical resilience of the surfaces. The IKA MIXSTER SET 3 0020027389 features a monolithic base plate made of highly chemically resistant glass. According to the manufacturer, this material is resistant to many aggressive reagents such as concentrated acids or organic solvents and is easy to decontaminate. An outstanding feature for use in demanding environments is the IP 66 protection rating. The system is dust-tight and protected against powerful water jets. In day-to-day laboratory use, this protects the internal electronics from spilled liquids and vapours. This robustness can lower the Total Cost of Ownership (TCO) through less downtime and longer maintenance intervals.

Cybernetic control and Lab 4.0 integration

The IKA MIXSTER SET 3 0020027389 is operated with tap buttons. The 360° LED glass display conveys all information without an alphanumeric readout and shows either the speed or the stirring power. With the integrated vessel detection, stirring also starts when the vessel is placed on the unit or touched. The reverse function changes the direction of rotation at definable intervals, and interval operation can be set from 6 s to 30 min. A USB interface is optional. The supplied power supply is designed for up to four devices; depending on the number of devices, a different power supply may be required.

Ergonomics and efficiency in modern laboratory layouts

Finally, the IKA MIXSTER SET 3 0020027389 stands out thanks to its extremely flat and space-saving design. With a height of just a few centimetres, the stirrers can be easily positioned in narrow safety workbenches or under fume hoods without adversely affecting the ergonomic working height. Compared to purchasing the units individually, the set offers a significant cost advantage and enables the immediate set-up of a high-performance multi-station workstation. The combination of the IP 66 protection rating and modular scalability makes this system a good choice for laboratories that prioritise precision, safety and flexibility.

Individual requirements & accessories

For highly viscous media or when working in special glass vessels, selecting a suitable stir bar shape is important to utilising the full torque of the IKA MIXSTER SET 3 0020027389. We recommend the use of IKAFLON stir bars with a PTFE or glass coating to reduce the risk of cross-contamination. For questions about accessories, such as additional MIXSTER stirring units (item no. 0020112621) or the MIX.IX and MIX.VX attachments, our procurement service is happy to help.
