Abstract

A filtration system and method for the filtration of a biological liquid are disclosed. The system and method may include a biological liquid collection assembly, a filtration assembly in communication with the collection assembly and a blood components preservative assembly in communication with the collection assembly. The preservative assembly includes a blood components preservative container and the preservative container may contain a blood components preservative solution and contains a measured quantity of a sterile gas. The preservative assembly is adapted to automatically transfer at least a portion of, respectively, the preservative solution, if present, and the gas to the collection assembly under a force of gravity once fluid flow communication is commenced between the preservative container and the collection assembly. Further, when the collection container contains at least a portion of the biological liquid and a transferred portion of the preservative solution, if present, and the gas, the collection container is adapted to automatically transfer at least a portion of, respectively, the biological liquid, the preservative solution, if present, and the gas to the filtration assembly under the force of gravity once fluid flow communication is commenced between the collection container and the filtration assembly.
