4.4 XDOS mode - controlled dosing
The XDOS mode (= Extended Dosing) of the 711 Liquino allows controlled
dosing of liquids with variable parameters. In principle it is possible to select
one of three different types of dosing. If continuos dosing is required a tan-
dem dosing setup can be used, i.e. dosing is carried out with a combination
of two Dosinos so that while one Dosino is being filled the other Dosino car-
ries out the dosing and vice versa.
Depending on the type of task one of the types of dosing listed below can
be used:
• Volume&Rate — you enter the volume to be dosed and the required dosing rate. Filling times
lengthen the dosing process.

• Volume&Time — you enter the volume and the time in which this volume is to be dosed (par-
ticularly suitable for synthesis applications). The dosing rate is automatically optimized by the
Liquino. The filling times of the dosing units are taken into account.

For tasks (volume and time) which cannot be fulfilled with the maximum dosing rate the 'max.
rate' will be used.
