XW Pack L Reagent for Sysmex XW-100 Analyzers

Laboratories running the Sysmex XW-100 Automated Hematology Analyzer depend on the correct reagents to produce accurate complete blood counts, and the XW Pack L is a core consumable in that workflow. This lyse reagent is manufactured by Sysmex America specifically for the XW-100 platform, so compatibility, cycle timing, and result integrity are validated by the analyzer's own maker rather than left to a third-party substitute.

The product we carry is the Sysmex America XW Packs L Reagent (ZA900006), supplied in a 2 x 250 mL configuration for whole blood sample processing. It is intended solely for use with the XW-100 analyzer, the CLIA-waived hematology system designed for physician offices, clinics, and other point-of-care settings that need on-site CBC results without a dedicated lab technologist.

Buyers ordering XW Pack L are typically restocking a running instrument, so what matters most is uninterrupted supply and lot consistency. Because reagent shortages can idle an analyzer entirely, many offices keep a spare pack on hand and reorder before the current one runs low. Store the reagent according to the manufacturer's labeled conditions and check expiration dating on receipt to protect result quality.

To keep your XW-100 fully provisioned, pair this lyse reagent with the companion diluent in our XW Pack D collection—together they cover the fluidics your analyzer needs for each run. If your practice also performs occult blood screening, you may find our ColoScreen III Office Pack and ColoCare Office Pack useful for rounding out point-of-care diagnostic supplies.
