Use the Thermo Scientific™ GC-Orbitrap™ High Temperature Nut and Ferrule Kit to obtain leak-free results in high-temperature transfer line settings for your Orbitrap gas chromatography (GC). The SCP-5000 high temperature Vespel ferrules (included) allow continuous transfer line temperatures of at least 320 °C without ferrule deformation or disintegration (as is common with standard graphite/Vespel ferrules above 280 °C), preventing leaks from forming over time. The included spring-loaded nut provides a tight fit between the nut, ferrule and transfer line, preventing further leak formation.
