Slide-Fix™ PAP jars with fuschia caps serve anatomic pathology, cytology, and research laboratories requiring a high-visibility, distinctively colored jar in their multi-reagent staining bench setup. Fuschia's pink-magenta hue is visually distinct from all other colors in the Slide-Fix™ set — no other cap color is easily confused with fuschia under typical bench or darkroom lighting conditions. This makes fuschia the ideal cap color for jars containing reagents where misidentification would be most consequential — fixatives, hazardous reagents, or time-critical immersion solutions where grabbing the wrong jar would cause an irreversible staining error.\u003c\/p\u003e \u003ch2\u003eU.S. Manufacturing, Quality \u0026amp; Institutional Procurement\u003c\/h2\u003e \u003cp\u003eCaplugs® Evergreen products are manufactured in the United States under ISO 9001 quality management from FDA-compliant, food-contact-grade resins.
