GENERAL DESCRIPTION
HI 180 are compact and lightweight magnetic stirrers. Lack
of laboratory bench space is no longer a concern.
They incorporate electronic controls that allow the user to
regulate the speed with greater precision.
In addition to speed control, the SpeedsafeTM system
assures that the maximum speed (1000 rpm) is never
exceeded.
Several HI 180 stirrers can be placed on the laboratory bench
and the colors will help in recognizing the different samples.
Their plastic cover will resist the harmful effects of any
accidentally spilled chemical.
Each stirrer is supplied with a magnetic stir bar (L 25 x dia
7 mm).
