Connectors for GC capillary columns
Features

	Graphseal ferrules for capillaries stainless steel ferrules filled with graphite – the ideal sealing material for capillaries The capillary is mounted on a 1/16" exit (detector, injector etc.) with the appropriate ferrule, a Graphseal nut (with slit) and an adaptor
	Glass connectors for fused silica capillary columns from 0.2 to 0.53 mm ID manufactured from deactivated glass with slightly tapered inner diameter; used to join two fused silica capillaries of equal or different diameters. Advantages compared to stainless steel fittings are easy connection without tools, optical control during connection, negligible heat capacity and no dead volume.
	PTFE shrinking tube can also be used for connecting capillaries. The minimum inner diameter expanded is 1.17  mm, the maximum ID shrunk is 0.40 mm. Shrinking occurs above 310 °C. Connections with PTFE shrinking tube are applicable up to 200 °C only. They should never be used above 250 °C.
