A method for rapid thermal control of a reaction volume from a preceding temperature to a target temperature includes first bringing at least the reaction vessel's second wall, which has high thermal conductivity, into direct contact with a first thermal block at a temperature higher than the target temperature if the target temperature is higher than the preceding temperature, or at a temperature lower than the target temperature if the target temperature is lower than the preceding temperature, until the reaction volume temperature is at least close to the target temperature; and then bringing the second wall into direct contact with a second thermal block at the target temperature. Also disclosed is a system () for detecting and/or quantitating a biological and/or chemical analyte in a sample and a software product for the system.

A photomultiplier used in liquid scintillation counting has an envelope, a base, an anode, a curved dynode structure and a photocathode. A specimen is inserted in a measuring area of the envelope for liquid scintillation counting. The photocathode has a concave surface, so that the specimen is encircled by the photocathode as completely as possible. The photocathode is positioned at a concave window of the envelope, so that a maximum number of photons directly impinge on the photocathode.
