GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTIONGENERAL DESCRIPTION
GENERAL DESCRIPTION
The Hanna series of bench top electromagnetic
stirrers are designed with simplicity of use for
stirring and mixing solutions in a wide range of
laboratory applications. Eighteen models are
available in an extensive range covering:
• mini-stirrers
• general purpose stirrers
• dual-speed range
• inverse cycle stirring
• rpm indication
• pH/ºC measurement
• timer control
• constant speed with feedback control
All models employ a motorized magnet to rotate
a stirring bar to create a forced vortex rotational
flow in the solution with a constant angular
speed which is adjustable with an external
speed knob. Unlike conventional stirrers, all
Hanna stirrers use the concept of pulse-driven
drive to give the full power required to effec-
tively stir the fluid regardless of the speed. This
eliminates the need to start the motor at high
speed and the user is now able to control the
speed precisely. Each stirrers is equipped with
an opto-sensor which monitor the speed and a
speed limiter circuit to prevent hazardous op-
eration when the load is suddenly removed.
The power required to effectively stir a fluid is
influenced by the torque load on the stirrer
which, in turn, is dependent on the capacity,
type and viscosity of the fluid. The speed of the
stirrer decreases as the torque load increases
and vice versa, unless the power delivered
changes accordingly. For Newtonian fluids like
water, the viscosity remains constant during
stirring. The mini and normal stirrers are ideal
for Newtonian fluids.
