Slide-Fix™ PAP Jar — Red Cap Applications

The red-capped Slide-Fix™ PAP jar is compatible with the following histology, cytology, and molecular pathology slide staining workflows.

Application Setting / Configuration Notes
Fixative (formalin) Histology bench, formalin fixation jar Red cap: alert color for formalin fixative hazard identification
Hazardous reagent marker Any hazardous staining reagent Red: universal hazard-associated color for dangerous reagents
Eosin (alternate assignment) H&E staining, eosin immersion Red for eosin when orange/fuschia are used elsewhere
Strong acid / mordant Lugol's iodine, iron mordant for Masson's Red cap for acid or mordant solutions
Xylene (neat, brief use) Clearing agent, deparaffinization Red cap: hazard identification for xylene-containing jar
FISH stringency wash Post-hybridization stringency wash Red: distinctive for stringency wash in FISH workflow
IHC substrate (chromogenic) DAB, AEC, or other chromogenic substrate Red for chromogenic substrate jar

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 red caps serve anatomic pathology, toxicology, and safety-conscious histology laboratories that assign hazard-associated colors to containers requiring extra handling awareness. Red cap jars are commonly designated for formalin (10% NBF), xylene-containing solutions, strong acid mordants, or other hazardous reagents where a universally recognized warning color prompts extra care during handling. In H&E staining protocols where color-coded jars are used to pace technicians through the sequence, red may mark the final step (eosin) or a time-sensitive immersion requiring precise timing.

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 (222-5450-L8S), Red , 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.
