Slide-Fix™ PAP Jar — Coplin-Style Slide Staining Jar, PPC, Natural Cap, Sterile, 10/Bag (222-5450-08S)
The Caplugs® Evergreen Slide-Fix™ PAP jar is a Coplin-style slide staining jar engineered for histology, cytology, and molecular pathology workflows. Constructed from polypropylene copolymer (PPC) with a natural (transparent) body and matching screw cap, each jar holds up to 10 standard 25 × 75 mm microscope slides on edge while fully immersed in staining solution, fixative, or reagent. Supplied sterile and pre-assembled in a 10/Bag pack, part number 222-5450-08S ships from USA inventory and integrates directly into sequential staining benches.

Applications
- H&E staining series: Sequential Coplin jars on the histology bench for hematoxylin, eosin, alcohol, and clearing steps; natural caps are ideal when all jars in the run contain the same reagent or when color coding is not required
- Papanicolaou (PAP) staining: Cytology labs processing cervical and respiratory cytology slides through the full multi-step PAP protocol
- Formalin fixation: Tissue slide fixation steps requiring full formalin compatibility and a vapor-retaining screw closure
- Alcohol dehydration series: Sequential 70%, 95%, and 100% ethanol immersion jars during tissue processing and deparaffinization
- IHC deparaffinization and antigen retrieval: Xylene-substitute clearing and heated buffer antigen retrieval, where a secure screw cap retains volatile organics
- Special stains: PAS, Masson's trichrome, Giemsa, AFB, and other histochemical protocols requiring up to 10 slides per run
- FISH hybridization: Probe hybridization and wash buffer jars where the transparent PPC body allows visual monitoring of slide position and fluid level without uncapping
Chemical Resistance
| Reagent / Condition | Compatibility |
|---|---|
| Formalin (10% neutral buffered) | Excellent |
| Ethanol (70%, 95%, 100%) | Excellent |
| Hematoxylin & eosin stains | Excellent |
| Xylene substitutes (e.g., Citrisolv, Sub-X) | Excellent |
| IHC reagents / aqueous buffers | Excellent |
| Dilute acids and bases | Excellent |
| Xylene (pure) | Not recommended — use xylene substitute |
| Chlorinated solvents (chloroform, DCM) | Not recommended |
Quality & Procurement
Made in USA, these Slide-Fix™ PAP jars are manufactured by Caplugs® Evergreen under ISO quality management from FDA-compliant, BPA-free, phthalate-free, latex-free PPC resin. The transparent jar body provides unobstructed visual monitoring of reagent fill level and slide position at a glance, while the pre-assembled screw cap ensures vapor containment for volatile fixatives and organic solvents. LabSupplies.com is an authorized dealer and ships from USA inventory, typically same business day for stocking items, with tiered pricing available for high-volume histology and pathology departments. Laboratories requiring reagent-specific color coding can pair the natural-cap 222-5450-08S with blue-cap (222-5450-B8S), orange-cap (222-5450-E8S), green-cap (222-5450-G8S), or fuchsia-cap (222-5450-K8S) variants to build a fully color-differentiated staining bench.
Frequently Asked Questions
Are these PAP jars supplied sterile?
Yes — the 222-5450-08S is supplied sterile and pre-assembled, ready for immediate use in cytology and histology workflows without additional processing.
Can these jars be used with full-strength xylene?
PPC offers excellent resistance to xylene substitutes such as Citrisolv and Sub-X, but direct use with pure xylene is not recommended. Most modern histology protocols have transitioned to xylene substitutes, which are fully compatible with this jar.
Why choose a natural cap instead of a colored cap?
Natural (clear) caps are the default when a single reagent fills all jars in the workflow, when no color differentiation is needed, or when labs maintain their own labeling system. If your bench uses multiple reagents simultaneously, Caplugs® Evergreen offers the same Slide-Fix™ jar in blue, orange, green, and fuchsia cap variants for step-by-step color coding.
How many slides does each jar hold, and what size slides are compatible?
Each jar accommodates up to 10 standard microscope slides measuring 25 × 75 mm, positioned on edge within the internal rack so all slides are uniformly immersed in the staining or fixation solution.
