Acid Alcohol - Histology & Microbiology Applications

Acid alcohol instantly decolorizes Gram-positive organisms while retaining Gram-negative cell wall staining.

Histology labs use 10-30 second dips removing hematoxylin excess from collagen while preserving nuclear staining.

Rapid action prevents over-decolorization maintaining diagnostic specificity in tissue sections.

1% HCl concentration optimized balancing speed and selectivity across multiple staining protocols.
