Abstract
A multi-compartment syringe for storing two or more substances in separate compartments comprises a tubular body having an opening at each end and a plunger. The body has two or more compartments defined along its length, where each compartment has a successively larger diameter. The plunger has a plunger head at one end that partitions the first and second compartments and one or more bungs, slidable along the plunger's shaft, for partitioning each of the other compartments. The plunger head and the bungs can be unsealed to establish a flow communication between the compartments.
