Hence, they are perfectly suited for clinical diagnostics, and support laboratory accreditations and audits.

Buffer acc. to Weise

Phosphate buffer solutions are used in hematology for the dilution of staining solutions and for rinsing steps in the staining process. Our buffer tablets acc. to Weise produce solutions that ensure stable and reproducible staining results. The tablets are offered with different pH values: pH 6.4 results in bright-orange erythrocytes with differentiated cells and nuclei; pH 6.8 results in orange erythrocytes; and pH 7.2 produces grayish erythrocytes with intense red-violet cells and nuclei.
