The invention provides container systems, kits and methods for peritoneal dialysis (PD) solutions. Such a system, for example, includes a first compartment that contains a PD osmotic agent and a second compartment that contains a PD buffer agent. The compartments maintain their respective contents separately from one another for purposes of transport, storage and/or sterilization. However, the compartments are fluidly couplable, so that their respective contents can be combined with one another, e.g., following sterilization of the agents and prior to their introduction into the patient's abdomen. The invention provides, in other aspects, such systems, kits and methods that provide protective structure which inhibits breaking of a seal prior between the second compartment and an outlet of the system, prior to breaking of a seal between the first and second compartments.
