IKA offers the ideal overhead stirrer for your stirring and mixing tasks in the lab - for lower to high viscosities. IKA overhead stirrers effortlessly process stirring quantities of up to 200 liters. IKA lab stirrers stand out due to their indispensable features, including an electronic safety circuit, a digital display, two speed ranges, and a controlling option via the lab software Labworldsoft. A broad spectrum of stirring tools is the key to successful mixing.
Functionality, safety, and longevity are the main goals in the development of IKA's overhead stirrers.
