| 20100043460 | CHILLER AND REACTION BLOCKS - A reaction block is provided that utilizes a refrigerant gas for cooling that includes a plurality of reaction stations each defining a reaction chamber for receiving a reaction vessel and defining a gas conducting passageway for conducting the refrigerant gas through the reaction station in temperature transmitting relation thereto. The reaction block also includes a metering means in fluid communication with a respective one of the reaction stations and is configured to receive a liquid refrigerant and to deliver an amount of refrigerant gas to the gas conducting passageway of one of the reaction stations in order to cool the contents inside the reaction vessel located at that reaction station. The metering means is also configured so that the amount of the refrigerant gas delivered to the gas conducting passageway of one reaction station is independent of the amount of refrigerant gas delivered to another one of the reaction stations. | 02-25-2010 |
