Opis

General description

Buffer tablets pH 7.2 - for preparing buffer solution according to Weise for staining of blood smears, are used to prepare buffer solutions according to Weise and pH-buffered staining solutions. Phosphate buffer solutions are used in hematology, for the dilution of staining solutions and for the rinsing steps in the staining process. The buffer tablets acc. to Weise will produce a buffered solution (pH 6.4/pH 6.8/pH 7.2) that stabilizes the staining result and gives reproducible staining results. Buffer solution according to Weise pH 6.4 results in bright-orange stained erythrocytes and differentiated stained cells with nuclei, whereby the erythrocytes are stained orange when using pH 6.8. Buffer solution acc. to Weise pH 7.2 produces grayish stained erythrocytes and intense red-violet stained cells with nuclei.
100 tablets are sufficient for 100 l buffer solution, each produced solution can be stable up to 4 weeks. Buffer tablets according to Weise are IVD products and CE registered. For more details, please see instructions for use (IFU). The IFU can be downloaded from this webpage.
