# Is it possible to remove a library pool from a sequencing reagent cartridge?

**If a library pool has already been loaded into a sequencing reagent cartridge, is it possible to remove the library and re-use the reagent kit with the same or a different library pool (if sequencing has not been performed)?**

Generally, once the library is loaded into a reagent cartridge, Illumina does not recommend removing the library pool. If sequencing is significantly delayed after loading a library pool, contact [Illumina Technical Support](https://www.illumina.com/company/contact-us.html#/united-states/technical-support) for additional information.
