Flow Cell Overview

C Flow cell cartridge frame
The flow cell is a glass-based substrate on which clusters are generated and the sequencing reaction is
performed. The flow cell is encased in a flow cell cartridge.
The flow cell contains 4 lanes that are imaged in pairs.
u Lanes 1 and 3 (lane pair A) are imaged at the same time.
u Lanes 2 and 4 (lane pair B) are imaged when imaging of lane pair A is complete.
Although the flow cell has 4 lanes, only a single library or set of pooled libraries is sequenced on the
flow cell. Libraries are loaded onto the reagent cartridge from a single reservoir and transferred
automatically to the flow cell to all 4 lanes.
Each lane is imaged in small imaging areas called tiles. For more information, see
Flow Cell Tiles

page 59.
Reagent Cartridge Overview
The reagent cartridge is a single-use consumable with RFIDtracking and foil-sealed reservoirs that are
prefilled with clustering and sequencing reagents.
Figure 5 Reagent Cartridge
The reagent cartridge includes a designated reservoir for loading prepared libraries. After the run begins,
libraries are transferred automatically from the reservoir to the flow cell.
