Nucleic acid amplification reaction station for disposable test devices

A station for performing an amplification reaction of nucleic acid in a disposable test device with first reaction chamber containing a first reagent nucleic acid amplification and a second reaction chamber containing, or in fluid communication with a second amplification reagent nucleic acid, the station comprising: a support structure for receiving said test device; at least one control system temperature to said analyzer device, said control system temperature maintaining said first reaction chamber at a first temperature but simultaneously maintaining said second amplification reagent of the nucleic acid to a second temperature different from said first temperature in order to preserve said second amplification reagent of the reaction.
