More Information
Summary:Biological fluid filtration methods are provided for the treatment of gas within a biological fluid filtration system. A quantity of biological fluid is flowed under the force of gravity through a leukocyte removal filter and into a post-filter container. The post-filter container has a maximum vented volume that is approximately the same as the quantity of biological fluid flowed through the filter and into the post-filter container. At least a substantial portion of the gas in the post-filter container is vented therefrom without separately restricting expansion of the post-filter container and without manually manipulating the post-filter container to expel gas.
