Experience reliability with the plug-and-play Thermo Scientific™ RT Basic Series Magnetic Stirrers, ideal for routine stirring applications. Three size options to choose from — 120mm, 170mm, or 220mm — all with a low-profile, lightweight design that has an extremely small footprint. The RT basic stirrers feature a chemical-resistant polypropylene top and body, a strong magnetic coupling to ensure consistent stirring during experimental procedures, and a brushless DC Motor that will not generate heat. Analog speed control ranges from 150 to 2500rpm. All units include two non-slip silicone plate covers for added protection from spills.
