A temperature control system for a syringe contained blood sample. Specifically, the system reduces the temperature of the blood sample to reduce the volatility of the blood gases. A first cylindrical member defines a chamber, the chamber accepting a blood sample containing syringe through an end thereof. A second, concentric cylindrical member cooperates with the first cylindrical member to define a reservoir surrounding the chamber. A heat sink material within the reservoir withdraws heat from the chamber to reduce the temperature of a blood sample within the chamber. In a preferred embodiment, the first and second cylindrical members are formed as integral structures having an end wall extending therebetween. A cap, which may be self-sealing with the two cylindrical members, forms an opposing end wall. Either end wall may function as a support to establish a desired chamber orientation. In a preferred embodiment, the cap provides the chamber support and is provided with flanges, which, selectively, stabilize the chamber such that its axis is either substantially vertical or slightly skewed from horizontal. When the unitary end wall supports the chamber, the cap may serve to center a blood sample containing syringe within the chamber.
