1 Nozzle Head
The nozzle head performs all pipetting steps. Its 8 nozzles can hold up to 8 reaction tips
per time. It also contains the tip-loss & clot-detection system (pressure sensor).
2 Magnet Unit
The magnet unit contains permanent magnets and can move forward and backward
from the rear of the chamber. For separation of magnetic beads from the buffers, the
magnetic plate moves closer to the reaction tips, thereby immobilizing the magnetic
beads on the inner surfaces of the reaction tips. The distance between magnet and reac-
tion tips is controlled by the software. The magnet unit also holds the drop catcher.
