Reagent holder, 1-trough 20 ml

The single-trough reagent reservoir from QIAGEN provides a 20 ml working volume for automated workflows on compatible QIAGEN instruments within the primary sample preparation portfolio. The unit drops into a reagent-carrier bay, cradling a single disposable trough so buffer, wash solution, or eluate remain stable during pipetting cycles. A labeled trough position aids reproducible loading between runs, while the rigid polymer body tolerates ethanol and isopropanol commonly used in nucleic acid cleanup protocols. Operators should verify alignment with the carrier rail before each run and empty the trough between batches to limit carryover. The accessory is supplied as a single holder and works alongside the rest of the QIAGEN reagent-carrier family, allowing laboratories to scale throughput on extended instrument decks. Intended for research use only in molecular biology, genomics, and clinical sample-preparation laboratories running QIAsymphony or comparable automated workstations.
