Slide-Fix™ PAP Jar — Lavender Cap Applications
The lavender-capped Slide-Fix™ PAP jar is compatible with the following histology, cytology, and molecular pathology slide staining workflows.
| Application | Setting / Configuration | Notes |
|---|---|---|
| Antibody diluent / blocking | IHC, antibody incubation step | Lavender: distinct from blue, assigned to antibody solution |
| Counterstain (hematoxylin) | H&E or IHC, nuclear counterstain step | Lavender differentiates from other blue-hued caps |
| PBS / TBS wash buffer | IHC wash steps, background blocking | Lavender for wash buffer in multi-step IHC protocol |
| Enzyme antigen retrieval | Proteinase K, pepsin digestion buffer | Lavender: enzymatic AR buffer identification |
| FISH probe buffer | Probe hybridization solution | Lavender for probe buffer in FISH staining series |
| Cytology rinse | Post-stain rinse, aqueous | Lavender cap for rinse jar differentiation |
| Scott's tap water substitute | H&E bluing reagent | Lavender for Scott's or other bluing solution |
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 lavender caps serve IHC, FISH, and multi-color cytology laboratories requiring a cap color between the primary blue and the more saturated purple. Lavender is visually distinct from blue at the bench even under dim microscopy room lighting — critical when IHC protocols use blue caps for wash buffers and lavender caps for antibody solutions, where the two reagent types must never be confused. FISH probe hybridization protocols use lavender to mark the probe buffer jar in a sequence that also includes blue (SSC wash) and orange (denaturation) jars.

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 (222-5450-K8S), Lavender , 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.
