SULFOLYSER Hematology Reagent for Sysmex Analyzers

SULFOLYSER is a liquid lyse reagent from Sysmex America engineered specifically for hemoglobin measurement on automated hematology analyzers. In the analytical cycle, SULFOLYSER lyses red blood cells and converts hemoglobin into a stable chromogen that the instrument reads photometrically, delivering the HGB value that anchors a complete blood count. For laboratories running Sysmex platforms, it is a validated, closed-system reagent that supports consistent, cyanide-free hemoglobin determination.

Laboratory buyers evaluating this reagent typically want to confirm compatibility, fill volume, and reorder cadence against test throughput. We carry SULFOLYSER in the formats that match common lab volumes:

• SLS-210A — 3 x 500 mL packaging, suited to lower- or moderate-volume benches where smaller container sizes reduce open-reagent waste.
• SLS-220A — a single 5-liter container for higher-throughput labs that want fewer changeouts and a longer run between reagent swaps.
• BJ350971 — 2 x 1.5 liter bottles, a middle-ground fill volume balancing shelf life and daily sample load.

Because SULFOLYSER is a manufacturer-specific reagent, using it as intended within the Sysmex assay chain is what preserves calibration integrity and result comparability across runs. Choosing the right container size comes down to your daily CBC volume, storage space, and how quickly your lab consumes an open bottle before its in-use stability window closes — larger fills favor busy reference and hospital labs, while the 500 mL packs work well for clinics and satellite sites. All formats are the same core liquid reagent; the difference is logistics, not chemistry.

Keep reagent inventory aligned with your analyzer's maintenance and QC schedule so hemoglobin reporting never pauses for a stock-out. Order SULFOLYSER in the fill size that matches your workload, and pair reorders with your other Sysmex consumables to simplify procurement.
