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).

SpeedsafeTM is a Trademark of Hanna Instruments.
