1. A collector for accessing a container assembly comprising:
a collector body having a proximal end, a distal end, and a sidewall extending between the proximal end and the distal end;
a penetrating needle cannula at the distal end of the collector body, the penetrating needle cannula comprising an open proximal end and a distal end shaped to pierce an elastomeric closure on a sample collection container; and
channel members extending outwardly from an inner surface of the sidewall of the collector body in a direction from the proximal end of the collector body to a distal end of the collector body and defining intervening capillary channels that are in fluid communication with the proximal open end of the penetrating needle cannula and guide fluid into the proximal open end of the penetrating needle cannula.
