TEMPERATURE CONTROL OF REACTION VESSEL, SYSTEM WITH REACTION VESSEL, SOFTWARE PRODUCT FOR SYSTEM AND USE OF SYSTEM

摘要

The invention relates to a method for rapid thermal control of a reaction volume (4) of a reaction vessel (2) for a change of temperature of the reaction volume (4) from a preceding temperature to a target temperature. Characteristic for the method is that the change of temperature is carried out by first bringing at least the second wall (8) of a second material with a high thermal conductivity of the reaction vessel (2) in direct contact with a first thermal block (14-19), at a temperature higher than the target temperature if the target temperature is higher than the preceding temperature, or correspondingly at a temperature lower than the target temperature if the target temperature is lower than the preceding temperature, for a time needed to bring the temperature of the reaction volume (4) to or close to the target temperature; and then bringing at least the second wall (8) in direct contact with a second thermal block (14-19) at the target temperature to bring the reaction volume (4) to the target temperature and/or keep the reaction volume (4) at the target temperature for the time intended. The first thermal block (14-19) is at a constant predetermined first temperature and the second thermal block (14-19) is at a constant predetermined second temperature. The invention also relates to a system (20) for detecting and/or quantitating a biological and/or chemical analyte or analytes in a sample supposedly containing said analyte or analytes for carrying out the method. The invention further relates to a software product for the system (20) and uses of the system (20).
