Abstract
A centrifuge system with a temperature control system for controlling the temperature of fractions removed or output from the centrifuge to a collection chamber. In one embodiment, the centrifuge system provides an integral heater element operable by a temperature controller to control the temperature of the collection chamber or dispenser assembly. A temperature sensor is provided to allow the temperature controller to accurately monitor the temperature of the fraction held in chambers or syringes in the dispenser assembly. In a more particular embodiment, the centrifuge system is utilized to separate and extract platelets from blood samples. The heater element is positioned adjacent collection syringes in the dispenser assembly and selectively operated to maintain the temperature of the platelets in the collection syringes within an activation temperature range to activate the platelets and facilitate creation of autologous platelet gel.
