1. Introduction
The HSC 7 heating magnetic stirrer with ceramic plate is used to heat and mix liquids inside a suitable container placed on
the ceramic plate. The stirring is possible thanks to a magnetic drive stir bar placed into the vessel.
The instrument is used in the laboratory for general use and for all those applications that require a regulation of the stirring
speed and of the heating plate temperature.
The ceramic heating plate allows to reach higher temperature than a traditional aluminium heating plate; furthermore, the
ceramic is an inert and very hard material, so it offers great resistance to almost any type of chemical or mechanical
aggression keeping the surface characteristics unaltered over time.
The heating plate works up to 400 °C.
The motor is able to stir up to 1300 rpm.
Note: it's important to choose the most suitable magnetic stirring bar related to the quantity and type of the liquid to be
stirred as well as to the type of the beaker. Size and shape of the magnetic stir bar determines the stirring efficiency at any
given speed. The stirring bar which satisfies most applications is code A00000356 (8 x 40 mm).
