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 unrivalled 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 maximum 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 cupboards.

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 stirring rod. 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 certification

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. This material offers virtually complete inertness towards aggressive reagents such as concentrated acids or organic solvents and can also be decontaminated without leaving any residue. 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 means that spilled liquids or corrosive vapours cannot damage the internal electronics, and the device can be cleaned under running water. This robustness significantly reduces the Total Cost of Ownership (TCO) by minimising downtime and extending maintenance intervals.

Cybernetic control and Lab 4.0 integration

The IKA MIXSTER SET 3 0020027389 is operated via an intuitive, glass-covered touch interface which has no mechanical wear parts and responds precisely even when operated whilst wearing laboratory gloves. The digital 7-segment display provides clear feedback on the kinetic parameters and the status of the timer function. In the context of Lab 4.0, the system’s connectivity is particularly noteworthy: all three units can be integrated into digital documentation systems (LIMS) via USB and RS 232 interfaces. In pharmaceutical production, this enables seamless traceability of stirring processes in accordance with GMP guidelines. Intelligent device recognition ensures synchronised control of all connected modules, allowing parallel test series to be carried out under absolutely identical physical conditions – a fundamental prerequisite for valid scientific data.

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 cupboards 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 a maintenance-free brushless drive, the highest protection class and modular scalability makes this system the first choice for forward-looking laboratories that prioritise precision, safety and flexibility.

Individual requirements & accessories

For highly viscous media or when working in special glass vessels, selecting the correct magnetic stir bar geometry is crucial to utilising the full torque of the IKA MIXSTER SET 3 0020027389. We recommend the use of IKAFLON stirring bars with a PTFE or glass coating to physically prevent cross-contamination. For digital process monitoring, the system can be supplemented with the Labworldsoft software (®) via the procurement service.
