Abstract

A reagent and wash fluid supply system for a flow through analyzing system which includes a tubular fluid sampling probe (70), having a sampling port (63) which aspirates air, sample and liquid reagents through the analyzing system which cooperates with a slide valve (64) having a passageway (53) through which the probe reciprocates. The passageway contains a plurality of chamber ports (46, 47, 48) each of which is sealed from the other ports by the tube sampling probe when its sampling port is positioned within a chamber port. A reagent pouch having a plurality of chambers communicating with a separate chamber port in the slide valve (20, 21) contains liquid reagents and a wash solution. One chamber in the reagent pouch receives waste.
