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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Biofluid collection and filtration device","description":"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 component","keywords":[]},"attribution":{"source":"Patentable","source_url":"https://patentable.app","canonical_url":"https://patentable.app/patents/US-9816087","license":"CC-BY-4.0-like","license_terms":"AI-generated analysis on this page (summary, layman_explanation, technical_analysis, business_analysis, faqs) may be reused with attribution and a visible link back to the canonical URL above.
