LLG temperature block exact; aluminium. Suitable for both cooling and heating; universally usable; uniform temperature distribution within the block; ideal for all temperature-sensitive applications. Aluminum blocks with conical compartments and closed bottom for easy and precise tempering of reaction tubes and PCR tubes. The precisely adapted shape of the borings and the closed bottom offer advantages compared with cylindrical drilled blocks with open bottom; such as much better heat transfer and temperature accuracy. Made of a special aluminum alloy with high thermal conductivity. Identical temperature conditions for all samples. Compact size; requiring little space. Suitable for 96-well plates; 8 or 12 strips and single tubes. Ideal for working with 8- or 12-channel pipettes. Blocks for different tube sizes and combinations of tube sizes as indicated; all working steps in one block; holes closed at the bottom and tapered to fit perfectly the respective tube sizes and offer an optimum heat exchange.
