Reuse Seal Set (20)

The QIAGEN Reuse Seal Set supplies 20 replacement sealing films for re-closing partially used reagent cartridges on QIAsymphony automated sample preparation systems. Each elastomer seal restores a secure closure on opened reagent packs, supporting continued use of buffer and binding mixtures between processing runs and minimizing reagent waste in routine molecular workflows.

The seals snap onto the cartridge port and remain piercable by the instrument pipetting tip, so re-closed cartridges can resume automated dispensing without manual intervention. They tolerate contact with chaotropic lysis buffers, ethanol wash solutions, and magnetic-particle suspensions commonly used in nucleic acid extraction protocols.

Storage is straightforward: keep the unused seals in the original pack at room temperature, away from dust and direct sunlight, to preserve adhesive integrity. Once a seal is applied to an opened cartridge, the cartridge should be consumed within the reagent's remaining shelf window as specified in the kit insert.

For laboratories running infectious disease screening or research-use sample-to-answer workflows, this pack of 20 supports re-sealing across multiple reagent cartridges during variable batch schedules, helping stabilize per-test consumable costs while maintaining automated throughput.
