Cone Tip<br />
Blunt end tip minimizes septa coring for use in GC autosamplers.<br />
HP Style Tip- Dual Gauge<br />
Special 90° blunt end tip for on column injection.<br />
Dual tapered design provides narrow entry point with<br />
high gauge strength to remaining length of needle..<br />

seals and stator face of manual injectors.Also minimizes fluid<br />
retention at needle end.<br />
