Frequently Asked Questions
Are these caps supplied pre-assembled on the PAP jars?
No — they are supplied unassembled, which reduces shipping volume and allows your team to fill jars with fixative and cap them according to your laboratory's collection protocol.
Are these caps compatible with 95% ethanol and other standard cytology fixatives?
Yes. Polypropylene Copolymer offers excellent resistance to ethanol, isopropyl alcohol, and commercial cytology fixative formulations, making these caps well suited for standard PAP smear fixation workflows.
What does the chocolate color indicate?
The chocolate color is used for color-coded PAP jar identification, allowing collection staff and laboratory technicians to quickly distinguish jar types at the point of collection and during processing without additional labeling.
Are these caps sterile?
No — they are non-sterile, which is standard for PAP jar fixation consumables used with chemical fixatives such as ethanol-based solutions. If your protocol requires sterile collection components, consult your laboratory's SOPs before use.
