Coulter Isoton III Diluent

Coulter Isoton III is a balanced electrolyte diluent formulated for use with hematology analyzers, where accurate cell counting and sizing depend on the consistency of the fluid carrying each sample through the aperture. Laboratories running complete blood counts rely on a diluent that maintains stable cell volume and conductivity, and this collection brings together the Isoton III reagent supplies that keep those instruments performing to spec.

If you manage a clinical or reference lab, the questions that matter here are compatibility, shelf stability, and throughput. Isoton III is designed to pair with Beckman Coulter hematology platforms, providing the isotonic environment cells need to be counted and measured without lysing or shrinking. Ordering in volumes that match your daily sample load helps avoid mid-run reagent changes and keeps your quality-control results reproducible from shift to shift.

Proper storage and handling protect your investment: keep containers sealed and within labeled temperature ranges, check lot numbers against your instrument calibration, and rotate stock so older lots are used first. Because diluent is consumed continuously during analyzer operation, most labs keep a reliable reorder cadence rather than waiting to run low.

Isoton III typically works alongside other Coulter-line reagents and controls in a complete hematology workflow. Explore related supplies such as Coulter ACT for automated coagulation timing, and browse the full Beckman Coulter range to keep your lab consumables consistent under one trusted line.
