Ferrules for PerkinElmer GC Systems

Column Ferrules for PerkinElmer GC Systems from Agilent

Agilent high-performance column ferrules for PerkinElmer GC systems are available in graphite, Vespel/graphite, and Vespel, all of which create consistent, leak-free seals with minimum torque. All column ferrules accommodate various column outer diameters and can withstand temperature cycling. In addition, the specially designed column ferrules prevent sticking to columns or other fittings. Whatever your application, Agilent's column ferrule portfolio can deliver excellent performance for use with your PerkinElmer GC systems.
