Applied Biosystems MicroAmp 3 x 32-well stand is designed for single tubes and strips on the ProFlex 3 x 32-well PCR system . Bearings provide support so that pressure is evenly distributed across individual pipes and unions to ensure proper sealing and prevent individual pipes and unions from being crushed or deformed. This holder is recommended for handling MicroAmp reaction tubes and connecting tubes. Simply place the holder on the sample module and insert the test tube or tube strip.
