These jars are fluorinated to resist absorption of contents.

Also known as oil analysis bottles, these are cleaned to have fewer than 10 particles larger than 10 microns per milliliter.

Each jar comes individually bagged and sterilized.

A sealing ring separates when the lid is opened.

Thread a wire tamper-seal tag through the holes in the lid and bottle. If the tag is cut or broken, you'll know the bottle has been opened.
