Sheath reagent for Spincell 5 Series
IVD
INTENDED USE
This product is designed to be used on a Spinreact 5-Part-Diff
haematology analyser along with Lyse and Sheath reagents produced
by SPINREACT, for testing the cell content in human blood.
FUNCTIONS
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.
INGREDIENTS
Trihydroxymethyl Aminomethane ＜1 g/L
Hydrochlocric Acid ＜0,2 g/L
