    AquaMax 2000/4000 Microplate Washer User Guide ® Program Management Commands You create programs to wash plates and perform maintenance. These programs or protocols are composed of basic primitives for wash functions (dispense, aspirate, wash, shake), program control (soak/pause, repeat), or maintenance functions (prime, purge, rinse). Firmware maintains these protocols in non-volatile storage, with a total of 103 slots available.

  • Page 140 AquaMax 2000/4000 Microplate Washer User Guide ® Aspirate (ASPI) Aspiration removes fluid from the plate. Vacuum begins prior to the needles coming into contact with the liquid surface. Vacuum continues as the needles descend at the specified rate to the specified position. The needles are left at the specified height for the specified time.
  • Page 141 Robot Command Interface Wash (WASH) Washing is simultaneous aspiration and dispensing. Aspiration begins as with whole plate aspiration. However when the aspiration needles reach the specified height, dispensing begins. No crosswise aspiration is allowed in this mode. The aspiration rate should be greater than the dispense rate.
