The very first laboratory equipment from Heidolph was the overhead stirrer RZR: affectionately named after the founder's name 'Rudolf Zinsser Rührer'. Since then, the overhead stirrer series has evolved enormously and, with its state-of-the-art engine technology, is the basis of an optimal stirring system.
From the compact Hei-TORQUE Core with 40 Ncm torque to the intelligent Hei-TORQUE Ultimate models (available in 100, 200 and 400 Ncm), all Heidolph overhead stirrers are very easy to operate. Equipped with the so-called Quick Chuck (quick-action chuck), it is easy to change the stirrer - without the need for extra tools. Depending on your application parameters, Heidolph can provide you with the right stirring tool.
