The PCE-MSR 100L magnetic stirrer is a professional instrument designed for mixing large volumes in laboratories, research, industry, pilot plants and technical processes. It is suitable when solutions, process liquids, aqueous mixtures, chemical preparations or high-capacity samples must be stirred using a stable, controllable system suitable for larger vessels than standard benchtop magnetic stirrers.

The maximum stirring capacity is up to 100 l, referred to water, making the instrument suitable for processes requiring high volumes. This feature makes it particularly useful for solution preparation, experimental batch mixing, scaled laboratory testing, biotechnological processes, water treatment, chemical production and industrial applications where uniform and repeatable mixing must be maintained.

The stirring plate is made of smooth stainless steel sheet and measures 400 x 400 mm. The large surface allows large vessels to be positioned stably, providing a robust and easy-to-clean base. Stainless steel is suitable for laboratory environments because it withstands daily use, supports easy maintenance and allows faster cleaning after mixing operations.

The PCE-MSR 100L is equipped with a 120 W brushless motor, designed to provide continuous operation and adequate performance even with large volumes. The brushless motor reduces mechanical wear compared with traditional brushed motors and helps make the instrument more reliable for repetitive use. This is important in laboratories and industrial environments where the stirrer may be used for prolonged cycles or daily tests.

The stirring speed can be adjusted from 100 to 600 rpm, with 5 rpm resolution and 10 rpm accuracy. This adjustment allows the motion to be adapted to the liquid characteristics, viscosity, vessel volume and process type. Lower speeds are suitable for gentle mixtures, sensitive samples or large volumes requiring stability, while higher speeds can be used when more mixing energy is needed to improve distribution of the contents.

The maximum stirring viscosity is specified as 34 cP. This value is useful for assessing compatibility with the fluid to be mixed. The device is particularly suitable for low-viscosity liquids, aqueous solutions and mixtures requiring stable magnetic stirring. For more viscous fluids or higher-density materials, the process compatibility with magnetic stirring and the type of stir bar used should be checked in advance.

An important function of the stirrer is the reversible stirring direction. Direction reversal helps improve liquid distribution and reduce stagnant zones or non-uniform mixing, especially when working with large volumes. This function is useful when the process requires homogeneous distribution of the medium, greater mixture uniformity or more stable movement control inside the vessel.

The integrated timer can be set from 1 minute up to 24 hours. This function allows defined-duration mixing cycles to be programmed, reducing the need for constant operator supervision. In laboratories and technical processes, time control is important for maintaining repeatable procedures, comparing different tests and following internal preparation or analysis protocols.

Control is carried out via an external unit with LCD display and central rotary control. This configuration allows intuitive operation and keeps the control section separate from the large stirring plate. The external unit makes it easier to read and adjust parameters even when a large vessel is placed on the plate. The control panel dimensions are 210 x 75 mm.

The overall dimensions of the stirrer are 400 x 400 x 95 mm, with a 160 mm stirring rod and an approximate weight of 7800 g. The robust structure and high weight contribute to stability during operation, especially with large-capacity vessels. The cable length is 1.5 m, providing flexibility for positioning on benches, technical trolleys or dedicated work areas.

The instrument has one stirring position and is powered from 100 to 240 VAC via a grounded plug. The protection class is IP21, suitable for laboratory environments and controlled technical areas. Operating conditions are 5 - 40 °C with relative humidity up to 80%, while storage conditions are 0 - 50 °C with relative humidity up to 80%.

Main applications include production of large quantities of solutions, reagent mixing, water treatment, biotechnological processes, pilot-scale sample preparation, university research, industrial testing and processes where the liquid must be kept in motion for a defined time. The PCE-MSR 100L is also suitable for laboratories that need to move from small experimental volumes to higher volumes while maintaining stable mixing control.

For reliable results, vessels with a bottom suitable for magnetic stirring should be used, the container should be centred on the plate, a magnetic stir bar suitable for the volume and liquid type should be selected and speed should be increased progressively. With large volumes, sudden acceleration should be avoided because it may cause stir bar decoupling, unstable vortices or non-uniform mixing.

The PCE-MSR 100L magnetic stirrer is therefore a professional solution for laboratories and industrial environments that need to mix large volumes with speed and time control. The combination of capacity up to 100 l, 400 x 400 mm stainless steel plate, 120 W brushless motor, adjustable speed, timer, reversible rotation and external control unit makes it suitable for robust, repeatable and manageable mixing processes in daily work.
