Ready to Clean Jars are designed for users who prefer to use their own cleaning process. Ready to Clean Jars are fully assembled with polypropylene caps and a friction fit .015" PTFE disc. Both cap and liner can be washed, heated, or autoclaved depending upon your application. The PTFE disc is chemically inert, and will not interfere with your test results.
Straight Sided Tall Glass Jars are designed without shoulders for maximum storage capacity and content visibility.
