Slide-Fix™ PAP Jar with Green Screw Cap — Coplin-Style Slide Staining Jar, PPC, Sterile, 10/Bag (222-5450-G8S)
The Caplugs® Evergreen Slide-Fix™ PAP jar is a Coplin-style slide staining jar engineered to hold up to 10 standard 25 × 75 mm microscope slides on edge while fully immersed in staining solution, fixative, or reagent. Constructed from optically transparent Polypropylene Copolymer (PPC) with a color-coded green screw cap, part number 222-5450-G8S ships sterile and pre-assembled in a 10/Bag configuration, ready for immediate integration into histology, cytology, and molecular pathology workflows. The transparent PPC body allows technicians to monitor reagent fill level and slide position at a glance without disturbing the jar, while the green cap provides an instantly recognizable color-code designation for a specific step — such as a dehydration alcohol, clearing agent, or probe solution — in a multi-jar staining series.

Applications
- H&E staining series: Color-coded caps distinguish sequential jars for hematoxylin, eosin, alcohol dehydration, and xylene/clearing steps along the histology bench.
- Papanicolaou (PAP) staining: The Coplin-style format is the standard vessel geometry for cytology slide staining in PAP smear protocols.
- Formalin fixation: PPC construction provides full compatibility with formalin for slide fixation steps in tissue processing workflows.
- Alcohol dehydration series: Green-cap jars designate a specific ethanol concentration (70%, 95%, or 100%) within a sequential dehydration rack, reducing error in high-throughput labs.
- IHC deparaffinization and antigen retrieval: Compatible with xylene substitutes; the screw cap retains volatile organic vapors and reduces exposure during immunohistochemistry protocols.
- Special stains: Suitable for PAS, Masson's trichrome, Giemsa, AFB, and other special stain series requiring batch processing of up to 10 slides per jar.
- FISH hybridization and wash steps: The transparent PPC body allows visual monitoring of probe hybridization and wash buffer levels; color caps differentiate individual wash jars in the protocol.
Compatibility
The Slide-Fix™ PAP jar is designed to accept standard 25 × 75 mm microscope slides on edge within its internal rack, making it compatible with the slide format used universally across clinical histology, cytopathology, and research staining workflows. The green-cap model joins a complete color-coded set within the Slide-Fix™ line — Natural cap (222-5450-08S), Blue cap (222-5450-B8S), Orange cap (222-5450-E8S), and Fuchsia cap (222-5450-K8S) — allowing laboratories to assign a unique color to each reagent or staining step and eliminate mix-ups in multi-jar series without relabeling between runs.
Chemical Resistance
| Reagent / Condition | Compatibility |
|---|---|
| Formalin (10% neutral buffered) | Excellent |
| Ethanol (all concentrations) | Excellent |
| Hematoxylin solution | Excellent |
| Eosin solution | Excellent |
| Xylene substitutes (e.g., CitriSolv, SafeClear) | Excellent |
| Aqueous buffers / saline / PBS | Excellent |
| IHC and FISH reagents (aqueous) | Excellent |
| True xylene (undiluted aromatic solvent) | Use with caution — verify with your specific reagent supplier |
| Acetone | Not recommended for prolonged contact |

Frequently Asked Questions
Are these staining jars supplied sterile?
Yes — the 222-5450-G8S ships sterile and pre-assembled with the green screw cap in place, 10 jars per bag, with no additional preparation required before use.
How many slides does each jar hold?
Each Slide-Fix™ PAP jar holds up to 10 standard 25 × 75 mm microscope slides standing on edge within the internal rack, allowing full immersion in reagent during staining.
Is the jar body compatible with xylene-based clearing agents?
The PPC jar body offers excellent resistance to xylene substitutes (such as CitriSolv or SafeClear) and standard histology reagents including formalin, ethanol, hematoxylin, and eosin. For true undiluted xylene, verify compatibility with your reagent supplier before long-term use.
Why would I order multiple cap colors from the Slide-Fix™ series?
Color-coding each jar to a specific reagent or concentration step — green for one solution, blue for another, orange for a third, and so on — lets bench technicians move through a multi-jar staining series confidently without relying solely on written labels, reducing the risk of cross-contamination or incorrect slide placement in high-throughput pathology workflows.
