Slide-Fix™ PAP Jar Red Caps — Polypropylene Copolymer, Non-Sterile, Unassembled, 1000/Bag (240-5400-R8K)
The Caplugs® Evergreen Slide-Fix™ PAP jar cap is a non-sterile, unassembled polypropylene copolymer (PPC) cap supplied in the red color used for color-coded PAP jar identification, packaged 1000/Bag for high-volume cytopathology programs. Designed for use with Slide-Fix™ PAP jars in Papanicolaou smear fixation and gynecological cytology workflows, the red cap seats securely to contain standard cytology fixative solutions during slide immersion and specimen transport. Part number 240-5400-R8K ships from USA inventory as an unassembled component, reducing shipping volume and simplifying high-throughput supply management.

Frequently Asked Questions
Are these caps sterile?
No — they are supplied non-sterile, which is standard for PAP jar fixation applications where the cytology fixative itself (typically 95% ethanol or IPA) provides the required preservation environment.
What does "unassembled" mean for this product?
Unassembled means the caps are shipped separately from the PAP jar bodies, allowing laboratories to store and dispense components independently, reduce shipping volume, and stock each component at the quantities their workflow requires.
Why are the caps red?
Red enables color-coded identification of PAP jar assemblies, helping cytology staff and OB-GYN personnel quickly confirm they are using the correct jar at the point of collection without consulting labels — a practical safeguard in high-throughput clinical settings.
Are these caps compatible with standard cytology fixatives such as 95% ethanol and isopropyl alcohol?
Yes — polypropylene copolymer provides excellent resistance to ethanol, IPA, and commercial cytology fixative formulations, making these caps well suited for standard PAP smear fixation protocols without risk of cap degradation or fixative leakage under normal use conditions.
