Do the foils sealing the EZ1 Reagent Cartridges have to be manually removed prior to loading the robot?
FAQ ID -1240

No, prefilled Reagent Cartridges can be loaded onto the BioRobot EZ1 with their seals. During operation of the instrument, the piercing unit, a row of 6 metal spikes located behind the tip adapters, will puncture the foil of the cartridges, thereby exposing the reagents.
