1. Introduction

MULTISTIRRER DIGITAL is able to stir up to 6 beakers having a maximum diameter of 85 mm (MULTISTIRRER DIGITAL
6) or up to 15 beakers having a maximum diameter of 64 mm (MULTISTIRRER DIGITAL 15) at the same time. The stirrer
stays cold even after several days of continuous operation. This feature makes it particularly appreciated in microbiology
and biochemistry. Epoxy painted metal structure, with stainless steel cover, are studied and tested in order to give to the
instrument an excellent resistance to the attack of chemical agents and to corrosion in general. The stirring speed can be
set within a range of 80 - 1500 rpm using the knob on the front panel. The Stirrer display shows when the speed set.
NOTE: it's important to choose the most suitable magnetic stirring bar related to the quantity and the liquid to be stirred as
well as to the type of the beaker. For MULTISTIRRER DIGITAL 6 is suggested the stirring bar A00001056 (6x35 mm); for
MULTISTIRRER DIGITAL 15 the A00001057 (6x20 mm).
