As we indicated in our response to Hailey, the arrow-shaped tip on a SPME Arrow facilitates the smooth penetration of vial and GC septa. We even demonstrated how well GC septa stand up to repeated Arrow injections. However, the following video clearly demonstrates how the Arrow tip enables end users to pierce a vial septum with less force. This means less force spread over a greater area (recall that the SPME Arrow has a beefier shaft than a traditional SPME fiber). All of this contributes to the robustness we have already covered. Without further ado, please enjoy the following video made by Beat Schilling:
