Get leak-free results in the high-temperature transfer line environment of your gas chromatography (GC) Orbitrap with the Thermo Scientific™ GC-Orbitrap™ High Temperature Nut and Ring Kit. High-temperature SCP-5000 Vespel ferrule (included) allows the transmission line to operate continuously at temperatures ≥ 320°C without deforming or damaging the ferrule (common with standard graphite/Vespel ferrules exceeding 280°C), preventing leakage after prolonged use . The included spring-loaded nut ensures a tight fit between the nut, ferrule and transfer line, further preventing leaks.
