Type III glass jars with solid-top, Teflon* resin-lined caps are for use in semivolatiles, pesticides, PCBs, and metals analyses. Jars with open-top caps have Teflon resin/silicone septa for sample integrity. They are prepared in a solvent-free facility to prevent possible volatile contamination and are for use in volatile organic analysis. Both types of jars are recommended for light-sensitive samples. Precleaned (PC) and Quality Assured (QA) bottles meet EPA specifications. QA bottles are supplied with a Certificate of Analysis. PC and QA cases are custody-sealed to ensure reliable chain-of-custody. Not Precleaned (NPC) bottles do not receive the specialty cleaning process. |
