DIFF-Line by CellaVision is a new workflow solution for low-volume hematology laboratories that consists of three instruments for smearing, staining, and analyzing peripheral blood smears: CellaVision DC-1, RAL SmearBox, and RAL StainBox. The CellaVision DC-1 single-slide analyzer automates and digitizes the process of analyzing peripheral blood smears; RAL SmearBox produces high-quality peripheral blood smears; and RAL StainBox stains blood smears consistently and by laboratory guidelines. This range of mutually supportive devices helps small labs to establish a simple and semi-automated process for preparing and analyzing peripheral blood smears.
