Magnetic mini stirrer, stainless steel cover, 110/115V. Common stirrers are manufactured with steel and aluminum components. These units are often too large and heavy to fit in the limited space of a laboratory. The HI 190M, HI 190MB and HI 200M are compact and lightweight, so that lack of laboratory bench space is no longer a concern. These stirrers incorporate electronic controls that allow the user to regulate the speed with greater precision. Often, in the lab, a sample is removed from the stirrer before reducing the speed. This would cause the motor of conventional equipment to accelerate until it is destroyed. This is not the case with the HANNA® mini-stirrers. In fact, the internal Speedsafe mechanism will ensure that the maximum speed is never exceeded. HI 200M is supplied with an AISI 316 stainless steel cover. This model is ideal for applications that create exothermic reactions.
