A fluid routing system for use in a fluid line is set forth which includes a fluid routing mechanism having a housing and a block, and a removable treatment device. The housing has an internal chamber, an inlet port for attaching to one part of a fluid line, an outlet port for attaching to another part of the fluid line, an inlet channel connecting the inlet port to the internal chamber, and an outlet channel connecting the internal chamber to the outlet port. The block is capable of movement between a first and second position and is disposed within the internal chamber of the housing. The block has a first internal cavity, a second internal cavity, an exterior surface, an inlet passageway connecting the first internal cavity with the exterior surface, and an outlet passageway connecting the second internal cavity with the exterior surface. The inlet passageway and the outlet passageway are configured to retain fluid therein when the treatment device is removed. In the first position, the inlet passageway of the block is aligned with the inlet channel of the housing and the outlet passageway of the block is aligned with the outlet channel of the housing for permitting flow of the fluid into the treatment device. In the second position, the inlet passageway of the block is misaligned with the inlet channel of the housing and the outlet passageway of the block is misaligned with the outlet channel of the housing for prohibiting flow of the fluid into the block.

A thermoelectric cooling apparatus includes a plurality of thermoelectric coolers each having a hot side and a cold side. The cold sides of the thermoelectric coolers are arranged to cool an object. The hot sides of the thermoelectric coolers are provided with a heat sink. The heat sink may include a eutectic material which maintains the hot sides of the thermoelectric coolers at a low temperature so that the cold sides of the thermoelectric coolers are able to maintain the object at a cold temperature. The heat sink may have fins for rejecting heat, and air moving means for moving air over the fins to aid in the rejection of heat from the hot sides of the thermoelectric coolers. The fins may be cooled by the eutectic material.
