These ferrules are made from 15% graphite and 85% Vespel®. They have a temperature limit of 350 °C and cannot be re-used with another capillary column.

• Mechanically robust, hard material, long lifetime
• Forms strong grip with column
• Must be re-tightened after initial temperature cycles
• For GC-MS interface

Poorly defined or selected connections can lead to an increase in dead volume, leaks from cycled temperatures and mismatched tubing sizes. Selecting the correct GC connections will improve your chromatography.

Temperature limit 350 °C.

Cannot be re-used.
