Rapi-Diff B - Cytology Counterstain Applications

Certified eosin counterstain achieves 2-second cytoplasmic staining supporting immediate morphological assessment across touch preps and FNA.

Cytology laboratories differentiate malignant plasma cytoplasm from inflammatory cells. Pink counterstaining prevents nuclear-only interpretation errors.

Quality control verifies eosin saturation, rinse compatibility, and 3-year stability. Buffered formulation prevents pH artifacts.
