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.
