Abstract: An automatic proportioner for proportioning a sample and a diluent for subsequent chemical analysis including a syringe driven by an actuator and controlled by a control system, a valve for selectively connecting the syringe to either a source of diluent in a receptacle or a source of sample, with diluent receptacle and valve being formed in a unitary assembly selectively removable from the main housing supporting the syringe and the control system components so that the receptacle, valve and syringe may be removed easily and replaced by another set.
