Depth filtration device for separating specimen phases

Abstract:

The present disclosure provides a biological fluid collection device, such as a blood collection device, that is adapted to receive a multi-component blood sample having a cellular portion and a plasma portion and quickly, efficiently and cost-effectively separate the plasma portion from the sample. A pressure gradient can be applied across a separation member to facilitate movement of the plasma portion ahead of the cellular portion. The present disclosure allows for both passive and active plasma separation and dispensing.
