A two-component fluid dispenser which can accurately mix two liquids of varying viscosity and then precisely deliver the mixture formed in discrete amounts. The mixture of the two components is delivered from a single delivery tube in a manner such that none of the mixture remains within the delivery tube at the completion of each mixing and delivery cycle. In one form of the apparatus, the single delivery tube of the apparatus is operably coupled with conventional hypodermic syringes of various sizes so that different fluids can be mixed in different ratios.
