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 fi…
