Abstract
The present specification discloses filtration devices for processing a biofluid sample, methods of purifying a biofluid sample using the disclosed filtration devices, and systems comprising components of the filtration devices. The filtration device generally includes a collection container, a quantitative container, a filter, and a plunger slidably inserted through a plunger attachment. In a first configuration, the quantitative container is axially slidably inserted within the collection chamber, with fluid communication between the quantitative chamber and the collection chamber provided through the filter. In a second configuration, the filter and the collection container are separated from the quantitative container, the plunger attachment is fitted to the quantitative chamber open end with at least a portion of the plunger positioned within the quantitative chamber.
