Abstract: In one embodiment, a biological sample analyzer has a housing having at least one outer wall that defines a cavity therein, an air intake, and an air exhaust. A plenum is disposed within the cavity and has at least one plenum wall that defines an air duct therein. A receptacle, which can support a consumable holder containing a biological sample, is disposed within the internal cavity. At least a portion of the receptacle is supported within the air duct such that an air gap is defined between the receptacle and the at least one plenum wall. A heater applies heat to the consumable holder so as to heat the consumable holder when the consumable holder is supported by the receptacle. A fan forces air along a path that extends from the air intake, through the air gap, and to the air exhaust so as to cool the heater.

Abstract: In one embodiment, a biological sample analyzer has a housing having at least one outer wall that defines a cavity therein. A receptacle, which can support a consumable holder containing a biological sample, is disposed within the cavity. At least one heater applies heat to the consumable holder when the consumable holder is supported by the receptacle. At least one heater sensor detects a temperature of the receptacle over time. A controller directs the at least one heater to apply an elevated temperature to the consumable holder and reduces an amount of heat applied to the consumable holder before the consumable holder exceeds a target temperature that is less than the elevated temperature. By applying the elevated temperature, the consumable holder can be heated quicker than if it where heated at only the target temperature.

Abstract: A method and biological sample analyzer is described that adjusts airflow within a housing based upon altitude. A first volume of air is moved by at least one fan within a housing of a biological sample analyzer. A temperature of the first volume of air is measured within the biological sample analyzer with a temperature sensor within the housing of the biological sample. Power output of at least one heater positioned within the housing of the biological sample analyzer is measured. The measured power output of the at least one heater is analyzed at the measured temperature within the biological sample analyzer. And, the fan is adjusted to move a second volume of air different from the first volume of air by comparing the measured power output of the at least one heater and expected power output of the at least one heater.

Abstract: In one embodiment, a biological sample analyzer has a housing having at least one outer wall that defines a cavity therein. A receptacle, which can support a consumable holder containing a biological sample, is disposed within the internal cavity. At least one heater applies heat to the receptacle when the consumable holder is supported by the receptacle. At least one heater sensor detect temperatures of the receptacle over time. A controller detects whether the consumable holder is below an ambient temperature based on a decrease in temperature of the receptacle when the consumable holder is inserted into the receptacle. The controller also increases an amount of thermal energy transferred from the at least one heater to the consumable holder when the controller detects that the consumable holder is below the ambient temperature so as to heat the consumable holder to a target temperature.
