Frequently Asked Questions
Are these caps sterile?
No — they are supplied non-sterile. PAP smear fixation workflows do not typically require sterile consumables, but please verify your lab's protocol requirements before ordering.
Do these caps come pre-assembled on the jars?
No — the 1000/Bag format is unassembled, meaning caps and jars are shipped separately. This reduces shipping volume and allows labs to reorder caps and jars independently to match actual usage rates.
What fixatives are compatible with the Polypropylene Copolymer material?
PPC offers excellent resistance to 95% ethanol, isopropyl alcohol, and standard commercial cytology fixative formulations. Chlorinated and aromatic solvents are not recommended for use with this material.
Can these caps be used with other PAP jar brands, or only Slide-Fix™ jars?
These caps are designed for the Caplugs® Evergreen Slide-Fix™ PAP jar system. Compatibility with third-party PAP jar bodies has not been confirmed — verify thread and dimension fit before substituting in another manufacturer's system.
