Slide-Fix™ PAP Jar Yellow Caps — Polypropylene Copolymer, Non-Sterile, 1000/Bag (240-5400-Y8K)
The Caplugs® Evergreen Slide-Fix™ PAP jar with yellow cap is a polypropylene copolymer (PPC) specimen container designed for Papanicolaou smear fixation and cytological specimen processing, supplied unassembled and non-sterile in 1000/Bag format for high-volume cytopathology programs. The yellow cap provides instant color-coded identification at the point of collection, and the PPC construction delivers reliable chemical resistance to standard cytology fixatives including 95% ethanol and isopropyl alcohol. Ordering as part number 240-5400-Y8K gives procurement teams a consistent, lot-traceable consumable well suited to CAP-, CLIA-, and ISO 15189-accredited laboratories.

Frequently Asked Questions
Are these PAP jar caps sterile?
No — they are supplied non-sterile, which is standard for cytology fixation applications where the fixative itself (typically 95% ethanol or IPA) controls microbial growth during slide immersion.
What does "unassembled" mean for this product?
The caps are shipped separately from the jar bodies, reducing shipping volume and allowing high-volume labs to assemble jars as needed. Both caps and jars are designed to mate securely in the standard Slide-Fix™ PAP jar format.
Why is the cap yellow?
Yellow serves as a color-coded identifier within cytopathology workflows, helping collection and processing staff quickly select and verify the correct jar at the point of collection without relying solely on label text.
Is polypropylene copolymer compatible with commercial cytology fixatives?
Yes — PPC offers excellent resistance to the alcohols and commercial fixative formulations most commonly used in gynecological cytology, including 95% ethanol and IPA-based products. Chlorinated and aromatic solvents are not recommended for contact with PPC.
