3 Design and Function

3.1 Function description

The Q3 dosing module can be added to any XPR analytical balance to perform automatic dosing of powders
and/or liquids. The powder or liquid dosing head is attached to the dosing module and stays outside of the
weighing chamber during the whole dosing procedure. The top door of the balance is replaced by a top panel
with an opening through which the powder or liquid is dosed. The top panel moves down with the dosing
module and the dosing head until the distance to the sample vessel is appropriate for dosing. The weighing
chamber is therefore closed during the whole dosing procedure, providing the best possible dosing perfor-
mances.
The Q3 dosing module is delivered with three ErgoClips: the ErgoClip adapter holder, the ErgoClip adapter
stabilizer, and the ErgoClip height extension. The different designs can accommodate vessels of different
sizes and shapes. All three ErgoClips are compatible with XPR analytical balances with tall draft shield.
When liquid is dosed, the QL3 pump and QLL kit for bottle are used together with the Q3 dosing module. The
QL3 pump is used to build pressure in the bottle. As soon as the pressure is sufficiently high, the micro
dispensing valve in the liquid dosing head opens and liquid ascends the liquid tube. Several pumps can be
connected to the balance simultaneously and each pump can accommodate up to three bottles.
