Sheath is a buffer solution that allows cells to flow uniformly and avoid
aggregation. Its osmotic concentration and ionic strength keeps the
integrity and the volume of WBCs. It lyses the RBCs to form ghost
cells which would not scatter the laser light to avoid affecting WBC
measurement. Sheath spherizes WBCs and optimizes their scattering
property. It also has humidifying effect to prevent accumulation of air
bubbles in WOC flow system.
This product is designed to be used on Hema25 5-Part-Diff
haematology analyser along with Lyse and Sheath reagents produced
by NS Biotec , for testing the cell content in human blood
