Abstract
A computer has been interfaced with a Durrum model 110 stopped-flow apparatus using a LabPro unit and LoggerPro software from Vernier Software and Technology. Two separate voltage probes from Vernier were used: one to monitor the trigger signal to initiate data collection and one to receive the output voltage signal from the stopped-flow apparatus. An experiment reacting iron(III) ion with thiocyanate ion in aqueous solution at 25 °C was used to test the reliability of the interface. The LabPro unit and LoggerPro software can be used to measure the data from most instruments normally connected to an oscilloscope or chart recorder.
Supplement
Further discussion regarding the operation of the stop-flow apparatus is available.
