The proprietary BioJet Elite technology was developed for high speed dispensing. The technology involves the coupling of a high speed micro solenoid valve with a high resolution syringe pump, and synchronization of the dispense system with the movements of the stage. The result is an extremely fast dispensing system which can deliver volumes from 20 nL to 4 µL in a single drop. BioJet Plus can work in either an Aspirate/Dispense or Bulk Dispense modes.
