Frequently Asked Questions
Are these caps sterile?
No — they are supplied non-sterile in an unassembled 1000/Bag format, which is standard for PAP jar fixation applications where sterility is not a requirement.
What fixatives are compatible with these PPC caps?
Polypropylene Copolymer offers excellent resistance to 95% ethanol, isopropyl alcohol, and commercial cytology fixative formulations commonly used in PAP smear and gynecological cytology workflows. Chlorinated or aromatic solvents are not recommended.
Why are the caps blue?
The blue color supports color-coded identification in cytology and gynecological specimen processing workstations where multiple cap colors are in use simultaneously, reducing the risk of mis-identification during high-volume processing.
Are these caps sold with jars, or do I need to order jars separately?
These caps are supplied unassembled without jars. Confirm your jar supply matches the Slide-Fix™ PAP jar format before ordering caps separately.
