As of November 2024, the PromethION Flow cell is no longer shipped with the light shield attached directly to the PromethION flow cell.

Going forward the PromethION Flow cells now ship with four PromethION light shields placed on the underside of the PromethION blister located underneath the scan me label, please see the below image. You can scan the affixed label for further instructions to position the light shield correctly on PromethION Flow cells.
