# Purge settings on the NextSeq 1000/2000 Users can choose to purge reagents from the cartridge once a run completes. Purging reagents will move the remaining contents from the reagent cartridge to the spent reagents compartment. 1. From the control software menu, select **Settings**. 2. Choose whether the system automatically purges unused reagents to the spent reagents compartment after each run to streamline waste disposal after run completion: * To purge automatically, select the **Purge Reagent Cartridge** checkbox\*. * To skip automatic purging, deselect the **Purge Reagent Cartridge** checkbox (this is the default setting). ![](https://761066130-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FGM9W2DuBTgEXv1ClCm8H%2Fuploads%2Fgit-blob-ead3bbaefb9cfc5367e79d551ef5f084a45f9ff5%2Fimage1.jpg?alt=media\&token=497ed2cf-c19c-4ad7-8a8c-2e9bc0f1f15d) 3.
