The MJ DNA Engine Tetrad (PTC 225) is a multi-user thermal cycler. The instrument consists of Peltier heated/cooled sample blocks (alphas) that have heated lids. Up to 7 users can run samples simultaneously and the alphas can accommodate 48-96 0.2 ml thin-walled PCR tubes/strips/plates or up to 30 thick-walled 0.5 ml tubes. The MJ Tetrad includes a gradient feature to perform annealing temperature optimization.
