a cap configured to inhibit a user from touching the air permeable blood barrier;
a sampling channel having a proximal end connected with the inlet port and a distal end connected with the outlet port, the sampling channel being configured to convey subsequent portions of blood past the chamber and to the outlet port after the first portion of blood has entered the chamber; and
a housing that houses and defines the inlet port, the outlet port, the chamber, and the sampling channel.
