At the two extremes of liquid handling lie pipettes and continuous pumps: in pipettes, the volume to be dispensed is discrete for each operation, while in pumps the volume is continuously dispensed and measured temporally, or also gravimetrically. Both are capable of high accuracy. Syringe pumps equipped with multi-source valves offer a good compromise since volumes are measured with a reciprocating piston, but the multi-source valve allows different reactants to be aspirated/dispensed with the same syringe in a semi-continuous fashion. We opted for multi-source syringe pumps (TriContinent C3000) so that titrant tubes could be rinsed, if necessary. After dispensing acid/base, pH measurements were performed with a slim profile pH probe (Sentron MicroFET). Its two-electrode design and built-in reference performed well with test samples and was easily incorporated into the probe head.
