Laboratory stirrers (also called laboratory stirrers, stirring elements or stirring motors) are indispensable for professional laboratories, the pharmaceutical industry, pharmacies and many other areas. They not only ensure a particularly uniform mixing result when homogenizing liquids and pastes, but also save time compared to manual mixing.
Due to individual stirring and mixing tasks in the various fields of application, specifically coordinated stirrers are required for optimum results. In addition to a uniform stirring result, uncomplicated operability and efficient, reliable motor performance play a decisive role.
The laboratory stirrers offered by Schmizo are the perfect solution for all stirring and mixing requirements in the laboratory, regardless of the specific viscosities and requirements. Whether you are looking for a lightweight stirrer motor for smaller quantities of low-viscosity liquids or a power unit for homogenizing high-viscosity media – you will find it with us.
With a high-quality laboratory agitator, you achieve significantly better mixing results than would be possible when homogenizing by hand. ven highly viscous substances can be stirred into a homogeneous mass without fatigue. The most important areas of application of the laboratory stirrer include:
The requirements for professional laboratory stirrer motors or laboratory stirrers are both diverse and high. The mechanics must function reliably, the electronics must be reliable and easy to operate. In addition, robust stirrer technology is required to optimize stirring processes.
We will work with you to find a stirrer for your laboratory that is perfectly suited to your tasks and requirements. You can rely on the fact that all laboratory stirrers from our portfolio are characterized by the following features:
The heart of the laboratory stirrer is a drive unit with operating elements, a stirrer motor and a clamping device for the stirrer shaft. The stirrer shaft is clamped into this with a stirrer blade suitable for the task. The speed of the stirrer motor is usually infinitely variable and is controlled electronically in modern laboratory stirrers. Many devices have a timer with which the desired stirring time can be set. After the time has elapsed, the stirrer motor switches off automatically.
Laboratory stirrers are usually designed to rotate slowly at first and to increase the stirring speed continuously. This prevents the substances to be mixed from spilling over the edge of the stirring vessel due to a too abrupt start. This is particularly important with aggressive or corrosive media.
Which laboratory stirrer is best suited to the task at hand depends essentially on the medium and the stirring tasks to be performed. In order to achieve the best possible results, it is advisable to pay attention not only to the device specifications but also to the use of the correct stirring blades. Further, agitator shaft should match the agitating medium, the agitating vessel and the required speed.
Depending on the device type, Schmizo laboratory stirrers offer you the following performance features:
Schmizo laboratory agitators are characterized by a robust design and a low-wear and low-maintenance construction. At the same time, they convince through high functionality, safety and maximum ease of use. We will be happy to assist you in selecting the right device for your application.
Of course, you can replace individual parts of the laboratory stirrers or supplement them with accessories. All offered stirrers fit all commercially available shaft diameters and stirrer types. In our store you will find a variety of suitable stirrers made of glass, stainless steel and PTFE.
All laboratory stirrers available from us have a maximum duty cycle of 100 percent. This means you can operate them around the clock without any problems.
In mechanical agitators, the speed is adjusted by means of a continuously variable transmission. A higher torque can be achieved in the low speed range by changing the transmission ratio. In the electronic agitator, a processor controls and monitors the output power. This ensures a constant speed even when the viscosity changes.
Our smallest devices can handle viscosities of up to 10,000 mPas. The most powerful ones can handle up to 100,000 mPas.
This depends on the viscosity of the media to be stirred. For water, the vessel should have twice the diameter and two to three times the height of the stirring tool. For viscous substances, a smaller distance between the vessel wall and the stirrer is recommended.
The ambient temperature should be between 5 and 40 degrees Celsius and the humidity should not exceed 80 percent.
