They feature an internal thread for use with a 15 mm PTFE bushing pressure seal. The unique design provides easy access into the vessel. For improved sealing, the O-ring is positioned on the bushing above the thread. These vessels are useful for pressure reactions and applications such as polymerization and halogen analysis by thermal decomposition in the pressence of lime. Complete vessels are supplied with PTFE bushing and Viton® O-ring. Replacement vessels are supplied without PTFE cap and O-ring.
