Abstract
A perifusion device includes at least one sample container for cells, the sample container having an inlet and an outlet. The container receives test liquid through the inlet and discharges the liquid through the outlet. A receptacle housing has a plurality of receptacles for receiving fluid from the outlet of the sample container. A drive is connected to the receptacle housing for moving the receptacle housing such that liquid samples are collected sequentially from the outlet of the sample containers. A computer can be provided to control movement of the receptacle housing at predetermined times, and to record data identifying liquid samples in the receptacles. The test liquid includes at least one stimuli for the cells, which can be the presence, absence, or concentration of a compound in the liquid, or a physical property of the liquid such as temperature. The liquid collected in the receptacles is analyzed to determine the response of the cells to the stimuli.
