How to Prevent Autosampler Needle Bending: The Advantages of 9mm Pre-Slit Bonded Cap-Septa2026-08-06Bent autosampler needles are among the most common mechanical failures in HPLC and GC labs, but the root cause often lies in the septum itself. This article examines the biomechanics of needle bending during septum puncture and explains how 9mm pre-slit bonded cap-septa eliminate puncture resistance, extend needle life by 3-5x, reduce particulate generation by 80-95%, and improve injection reproducibility.
