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

: i

t’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).
