METTLER TOLEDO's XPR analytical balances can be fitted with the optional liquid dispensing module. This laboratory liquid dispenser doses liquid directly into a container on the XPR analytical balance weighing pan. By using the density of the liquid and the ambient temperature, the weight of the liquid is interpreted as a volume. The advantage of the XPR automatic laboratory liquid dispenser is that, when making a solution of a desired concentration, the precise amount of liquid can be added according to the actual dosed quantity of the substance to create highly accurate solutions.
