Patent attributes
The invention concerns a thermal cycler and a microtiter plate. The cycler comprises a sample holder having a first surface and a surface and means for automated, controlled heating and cooling of the sample holder. The first surface of the sample holder is designed to hold a plurality of samples arrayed in a grid having a predefined pitch. The number of samples in one dimension is an exact match of the SBS plate standards for that sample pitch and in another dimension corresponds to a fraction of the number of samples in a second dimension of an SBS microtiter standard plate. According to the invention, the sample holder is shaped such that the area of the second surface is larger than the area of the first surface. By means of the invention, the thermal ramping speeds of the cycler can be significantly increased.
