Specification of volume and dosing time
You define the volume and the time in which this volume is to be dosed
(particularly suitable for synthesis applications). The dosing rate is auto-
matically optimized.
The time defined as Dosing time corresponds to the net dosing time t

,
i.e. the filling time of the exchange or dosing unit is included in the total.
If the specifications with the maximum dosing rate cannot be achieved,
then dosing is carried out at the maximum rate. The following formula can
be used to estimate whether the maximum dosing rate is used or not:
Dosing rate = desired flow rate in mL/min • 2.22
Note
This formula applies only for using a single dosing device. The dosing
rate is equal to the flow rate in the case of tandem dosing.
If the required dosing rate exceeds the maximum dosing rate for the selec-
ted exchange or dosing unit (or cylinder volume, respectively), then a
larger cylinder volume must be selected.
Specification of dosing rate and dosing time
You define the dosing rate with which dosing is to be carried out during a
particular time. As in the previous case, the filling times are not included in
the total, and dosing is prolonged accordingly.
