Frequently Asked Questions
Are these caps sterile?
No — they are supplied non-sterile. PAP smear fixation workflows do not require sterile containment, but labs with specific aseptic handling requirements should evaluate accordingly.
What does "unassembled" mean for this product?
The caps are packed separately from the PAP jar bodies, which reduces shipping volume and allows labs to assemble jars as needed rather than receiving pre-assembled units that take up more storage space.
Are these caps compatible with standard cytology fixatives such as 95% ethanol?
Yes — Polypropylene Copolymer provides reliable chemical resistance to 95% ethanol, isopropyl alcohol, and commercial cytology fixative formulations commonly used in PAP smear and gynecological cytology workflows.
Why are the caps orange?
Orange is used for color-coded PAP jar identification, helping collection and laboratory staff quickly distinguish the correct jar type and reducing the risk of specimen mix-ups in multi-product cytology supply environments.
