Membrane-based double-layer tube for sample collections
摘要
The fluid sample collection device is adapted to collect and separate a fluid sample into constituent parts such as separating plasma or serum from a blood sample. The device includes an evacuated outer container and an inner container. The outer container has a first open end and a second closed end. A pierceable closure closes the first open end thereby defining a first interior chamber. The inner container is contained within the outer container and separates the first interior chamber into an upper chamber portion and lower chamber portion in fluid communication. The inner container defines a second interior chamber separated from the lower chamber portion through a porous membrane. A port is provided for placing the second interior chamber in fluid communication with the first interior chamber. Another aspect of the device relates to a method of using the device to separate plasma or serum from a blood sample.
