A reservoir for use with a blood collection system includes a housing, a pre-filter, and a spring mechanism. The housing defines a cavity and has an inlet for receiving fluid from a source. The pre-filter is located within the cavity, removes particulates contained within the fluid, and allows the fluid to pass through the pre-filter. The spring mechanism is connected to the pre-filter and allows the pre-filter to travel within the cavity as the pre-filter collects particulates.
