  • Patent number: 7875242
    Abstract: Apparatus and methods for treating hematological, cytological, or histological specimens deposited on slides are disclosed. The apparatus comprises a first heating station, a second heating station, and at least one processing station adapted to receive specimen slides. A lifting device moves a first set of the specimen slides and a second set of the specimen slides among the first heating station, the second heating station, and the at least one processing station. A controller independently controls the temperature of the first and second heating stations and selectively positions each of the first and second sets of specimen slides within at least two of the first heating station, the second heating station, and the at least one processing station.

  • Publication number: 20050092001
    Abstract: A method and apparatus for controlling the temperature of a cold plate is disclosed. The temperature of the cold plate is controlled by directing compressed refrigerant along a first path configured to supply cooled refrigerant to the evaporator of the cold plate, redirecting at least a portion of the compressed refrigerant along a second path configured to supply non-cooled refrigerant to the evaporator of the cold plate, comparing a temperature reading associated with the cold plate to a predefined temperature range, and incrementally controlling the portion of the compressed refrigerant redirected along the second path responsive to the compared temperature reading. The temperature of the cold plate may be controlled to defrost the cold plate by redirecting substantially all of the compressed refrigerant along the second path for a predefined period of time responsive to a shutdown indicator.

  • Publication number: 20040033169
    Abstract: An automated slide stainer with fluid flow control. The fluid flow control controls the flow rate of fluid, e.g., water, applied to at least one slide by the slide stainer. In an automated slide stainer that applies reagents to slides to stain biological specimens on the slides, the flow rate controlled fluid can be used to adequately rinse the slides without damaging the biological specimens contained on the slides.
