A biological fluid collection device () that produces a stabilized biological sample with head-to-tail uniformity through the capturing of a high concentration front and subsequent redistribution of the high concentration front throughout a biological fluid is disclosed. The biological fluid collection device includes an inline mixer () used for head-to-tail mixing of a concentrated flow front. The mixing is achieved via a two-stage process. First, a front fraction of the flow is captured within a centered mixing chamber () via capillary assisted flow action. Second, the captured front volume is then slowly released throughout a small exit hole () and recombined with the rest of the flow volume that was diverted around the centered mixer chamber.

Biological fluid collection device

A specimen mixing and transfer device adapted to receive a sample is disclosed. The specimen mixing and transfer device includes a housing, a material including pores that is disposed within the housing, and a dry anticoagulant powder within the pores of the material. In one embodiment, the material is a sponge material. In other embodiments, the material is an open cell foam. In one embodiment, the material is treated with an anticoagulant to form a dry anticoagulant powder finely distributed throughout the pores of the material. A blood sample may be received within the specimen mixing and transfer device. The blood sample is exposed to and mixes with the anticoagulant powder while passing through the material.
