Circulators

LABORATORY TYPE
CIRCULATOR

Laboratory shakers are motorized mixing devices used for homogeneous mixing, incubation, or dissolution of liquid samples. They provide controlled mixing in various applications with different shaking motions (orbital, linear, circular, reciprocal, etc.). Temperature-controlled models enable simultaneous shaking and incubation processes. These devices are indispensable in biological, chemical, and pharmaceutical processes where sample sensitivity is high.

Orkalab laboratory shakers offer precise, quiet, and reliable mixing solutions with different capacity and motion options.
