1 Overview
1.1 Application range
The Metrohm 711 Liquino is a very versatile laboratory instrument which can
be used everywhere that liquid handling is to be simplified and automated.
This is the case in both analytical laboratories and in synthesis laboratories.
It is equally suitable for both the preparation of complicated formulations in
filling plants and also for simple delivery and pumping tasks involving toxic
or aggressive media.
Owing to the freely programmable process sequences and versatile com-
munication interfaces (RS232 or remote connection) it can be integrated in-
to complex automated systems to undertake demanding dosing and moni-
toring functions, which otherwise would only be capable of realization with a
considerably greater expenditure.
1.2 Application possibilities
The 711 Liquino can be used for the whole range of applications which fall
under the general heading of 'Liquid Handling'.
In analytical laboratories
• manual, highly accurate liquid dosing.
• complex, process-controlled dosing tasks with freely selectable specifi-
cations, e.g. a certain volume in a given period, constant dosing speed
during a preselected time interval, a certain volume with constant dosing
speed. In addition this can also be temperature-controlled, i.e. if a cer-
tain temperature limit is exceeded or undercut during the dosing process
then the dosing process can be interrupted and a predefined action trig-
gered, e.g. switching on a cooling bath.
• automated preparation of defined solutions (e.g. standard solutions) or
mixtures of liquids (e.g. mobile phases for HPLC or IC). It is possible to
connect a balance without any problems.
• highly accurate pipetting and diluting even small volumes of liquid.
• automated sampling and sample preparation for a range of analytical
methods (e.g. titrations, pH measurements, etc.) with and without a
sample changer.
• preparation of complex formulations in automated filling plant.
In synthesis laboratories
• manual, highly accurate liquid dosing.
• complex, process-controlled dosing tasks with freely selectable specifi-
cations, e.g. a certain volume in a given period, constant dosing speed
during a preselected time interval, a certain volume with constant dosing
speed. In addition this can also be temperature-controlled, i.e. if a cer-
tain temperature limit is exceeded or undercut during the dosing process
then the dosing process can be interrupted and a predefined action trig-
gered, e.g. switching on a cooling bath.
