Stable to 550 °C.
Use with any 1/16" compression-type fitting.
Description
Alumaseal ferrules combine the advantages of graphite and Vespel/graphite ferrules, and eliminate the disadvantages, for enhanced performance in any application. The unique front and back ferrule design seals easily and surely, the ferrules will not fragment or off-gas, and they are stable to 550 °C. Alumaseal ferrules will not allow oxygen to permeate into the system, and do not require retightening after temperature cycles, making them ideal for GC-MS applications. They can be used with any standard 1/16" compression-type fitting with fused silica columns.
For leak-tight seals, we highly recommend you try Alumaseal ferrules.
