Features

	Graphite ferrules provide the highest temperature stability (up to 450 °C). They are reusable when handled with care. We also offer 1/16" graphite ferrules specially designed for Carlo Erba / Fisons or for Agilent gas chromatographs.
	Vespel ferrules come in three types: pure Vespel, Vespel with 15 % graphite and Vespel with 40 % graphite. All versions are stable up to 400 °C and reusable.
	Teflon ferrules can only be used up to 250 °C. They are not reusable and not recommended for temperature programming. However, they show the best chemical inertness of all ferrules.
