method for closing at least a pocket from a number of a plate is provided for the inclusion of chemical and / or biochemical and / or microbiological agents anda device for implementing the procedure

摘要

Disclosed is a plate (2) with at least one well (11) designed to hold chemical and/or biochemical and/or microbiological substances. The well has an interior space delimited by its inside surface, plus a wall. The outside surface (28), remote from the inside surface, of the wall includes a heat-exchange surface (28') at least part of which can be brought into thermal contact with a temperature-equilibrating agent. The plate (2) is characterized in that the at least one well (11) has a heat-transmission coefficient which is greater than 5 x 10?-4 W/(K mm?3). The heat-transmission coefficient is given by the formula: (A . $g(l))/(V . x), in which A is the area of the heat-exchange surface (28'), $g(l) is the thermal conductivity of the wall material, V is the internal volume of the well (1) and x is the wall thickness, taken as the distance between the heat-echange surface (28') and the inside surface of the well. W represents the heat-transmission coefficient.
