Slide-Fix™ PAP Jar — Fuschia Cap Applications
The fuschia-capped Slide-Fix™ PAP jar is compatible with the following histology, cytology, and molecular pathology slide staining workflows.
| Application | Setting / Configuration | Notes |
|---|---|---|
| H&E — Eosin step | Histology bench, eosin immersion jar | Fuschia: distinctive from blue (hematoxylin) and green caps |
| Cytology fixative | PAP smear fixation, Carbowax or EtOH | Fuschia cap for immediate visual identification of fixative jar |
| Immunofluorescence wash | IF protocol, PBS wash buffer | Fuschia for one specific wash buffer in multi-step IF protocol |
| Special stain reagent | PAS, Alcian blue, or other special stain | Fuschia differentiates from H&E reagent jars |
| FISH wash buffer (SSC) | FISH protocol, saline-sodium citrate wash | Fuschia: distinct from other wash buffer colors in FISH set |
| Counterstain solution | IHC counterstain (e.g., nuclear fast red) | High-visibility fuschia for counterstain identification |
| Deparaffinization step | Xylene substitute immersion | Fuschia caps mark clearing agent in tissue processing series |
Chemical Resistance — Polypropylene Copolymer (PPC) — Histology Reagent Compatibility
Compatibility reference for PPC at typical laboratory conditions.
| Reagent / Condition | Compatibility | Notes |
|---|---|---|
| Formalin / formaldehyde (10%) | Excellent | PPC: full formalin compatibility for slide fixation. |
| Ethanol (70–100%) | Excellent | PPC compatible with full dehydration ethanol series. |
| Xylene substitutes | Excellent | PPC compatible with standard xylene substitutes. |
| Hematoxylin / eosin | Excellent | H&E staining reagents fully compatible. |
| Methanol / isopropanol | Excellent | PPC: full methanol compatibility. |
| IHC antibodies / buffers | Excellent | PBS, TBS, antibody diluent all compatible. |
| Xylene (neat) | Limited | Brief contact acceptable; avoid extended xylene immersion. |
| Concentrated H2SO4 / NaOH | Limited | Avoid concentrated acids or bases. |
Clinical & Research Laboratory Applications
Caplugs® Evergreen 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.

Frequently Asked Questions
Are the Slide-Fix™ PAP jars sterile?
Yes. Sterile — packed 10/Bag Assembled.
What is the complete Slide-Fix™ PAP jar color set?
Eight colors: Natural (222-5450-08S), Blue (222-5450-B8S), Orange (222-5450-E8S), Green (222-5450-G8S), Fuschia , Lavender (222-5450-L8S), Red (222-5450-R8S), Yellow (222-5450-Y8S). All are identical PPC jars at the same price — only the cap color differs.
Is there a standard color convention for Slide-Fix™ PAP jar reagent assignment?
There is no universal mandated convention — each laboratory assigns reagents to cap colors per their own SOP. Common practices include: Red/Orange for fixatives or hazardous reagents; Blue for wash buffers; Lavender for antibody solutions; Yellow for substrates; Natural for neutral or final rinse solutions. The eight-color set allows each lab to establish and document their own color-coding scheme that fits their specific staining protocols.
