It is designed to accommodate 96 x 0.2 mL PCR tubes and 6 x 1.5 mL tubes, ensuring uniform temperature distribution for all samples. Crafted from a special aluminum alloy with high thermal conductivity, this block is suitable for both cooling and heating applications, making it ideal for all temperature-sensitive laboratory procedures. Its compact size requires minimal space, and the precisely adapted shape of the borings with closed bottoms offers superior heat transfer and temperature accuracy compared to cylindrical drilled blocks with open bottoms.
