High Purity Wrights Stain CAS 68988921 China Suppliers and Factory
Wright's stain is a premier polychromatic biological dyeing agent engineered for high-precision hematology and histology. By utilizing a sophisticated blend of eosin (acidic dye) and methylene blue (basic dye), it provides exceptional cellular differentiation, allowing clinicians and researchers to distinguish blood cell types with absolute clarity under microscopic examination.
Specifically formulated for peripheral blood smears and bone marrow samples, this stain is indispensable for the rapid diagnostic identification of anemia, infections, and leukemia. It ensures a vivid contrast where nuclei appear purple-blue and cytoplasm appears pink, delivering the critical morphological data required for accurate medical pathology and laboratory research.

Frequently Asked Questions
It is primarily used in hematology to differentiate white blood cells, red blood cells, and platelets in peripheral blood smears and bone marrow samples.
Wright's stain is faster and ideal for clinical blood smears, while Giemsa stain offers superior contrast for parasites (like malaria) and requires a buffer for pH optimization.
While it can highlight certain bacteria (like Rickettsia) in purple-blue, it is not a substitute for Gram staining as it cannot classify bacteria into Gram-positive or Gram-negative.
The product is insoluble in water but dissolves readily in organic solvents such as methanol and ethanol.
It falls under Specialized Chemical Manufacturing, specifically as a biological staining agent and organic intermediate.
It is professionally packaged in 25kg fibre drums to ensure stability and safety during long-distance transit.
