Magnetic Stirrers, Overhead Stirrers
Laboratory Stirrers - areas of application
The laboratory stirrers, magnetic and overhead stirrers in our online shop are excellent laboratory devices which due their technical features are mainly used in the laboratory for the stirring, mixing and heating of viscous and fluid media. The mechanical and electrical stirrers are employed in chemical, biological, medical or pharmaceutical research laboratories, science and industry. Above all, it is universities, specialist colleges and biotechnological, food, chemistry or environmental production plants that order the offered laboratory stirrers. In principle, with the laboratory stirrers, through various stirring processes and types of stirring you can carry out various processes in the laboratory such as the homogenisation, suspension, dissolution, crystallisation, gassing or heating of substances and fluids. Which laboratory stirrer should be used for this essentially depends on the medium and the stirring tasks, volumes, stirring drive, speed, control and number of stirring tools. We are happy to advise you on the selection of the right stirrer for your applications in the laboratory: +49(0)3338 - 75 10 456.
Laboratory Stirrers & Stirring Systems - manufacturers and models
ProfiLab24 offers lab stirrers by renowned laboratory equipment manufacturers such as IKA, Heidolph, 2mag, BioSan, witeg, Bochem or Ingenieurbüro CAT M. Zipperer, which guarantee precise and reliable work in the laboratory, In our laboratory stirrer range we primarily distinguish between magnetic stirrers and overhead stirrers / stirring systems. These range from mechanical stirrers, rod, hand and measuring stirrers to digital stirring systems; one-place and multiple-places magnetic stirrers with internal or external control as well as heating stirrers with an integrated hot plate and explosion-protected laboratory stirrers. In practice it is possible to stir almost every fluid up to a certain viscosity with a magnetic stirrer or mechanical overhead stirrer. In the case of media with a moderate or very high and fluctuating viscosity it is advisable to use electric laboratory stirring systems as these laboratory stirrers can transmit great forces at constant high speed.
Laboratory Stirrer - functions, propeller, speed
Depending on the medium and selected process, the laboratory stirrers have different functions and options. Conventional laboratory stirrers basically consist of a stirring drive as the motor of the laboratory stirrer as well as the stirring tool that transmits the rotation of the stirring motor into the relevant medium, whereby the suitable combination of stirring drive and stirring tool is also decisive for the mixing and stirring of the laboratory stirrer. Whereas the function of a magnetic stirrer is based on the magnetic coupling of the stirring rod in the fluid with the rotating magnets in the laboratory stirrer, powerful laboratory stirring systems generally have a drive with a clamping device for the stirring shaft (similar to a drill) with the suitable stirring blade or propeller stirrer. Modern laboratory offer the possibility of limiting and electrically controlling various flows and speeds or to stir at incremental or continuously regulated speeds. Depending on the method, medium and quantity to be stirred there are laboratory stirrers with different speeds as well as speed measurement and display which through the measured speeds allow conclusions to be drawn with regard to the viscosity along with the relevant factors such as the stirrer geometry, filling level, speed and temperature.
