A rocker is a device used in laboratories for molecular and biological mixing applications. Rockers are often used in place of shakers when less aggressive mixing is required. Typical features of laboratory rockers include variable speeds, and tilt angles. A laboratory rotator and mixer is an assembly of different systems for vigorously agitating and mixing different samples. Implying, by using a laboratory mixer you will get a suitable mixture for your applications. Despite the fact that there are many laboratory mixers in the market, magnetic stirrers are the most common.
