Inserts, Low Volume for Vials, Glass. Clear, 100ul fill volume with a conical, precision point and 5x31mm outer dimensions. For use in 8mm, narrow mouth, 2ml autosampler vials. AQ Brand. 100/PK.
Additional Info:
Optimize ultra‑low volume sample recovery with a self‑aligning insert designed for consistent, spring‑free performance.
9503S‑05N inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass, offering excellent chemical resistance and purity for HPLC and LC‑MS workflows. The precision conical tip concentrates sample at the bottom of the insert, improving recovery and ensuring consistent needle access, even with very limited sample volumes.
With a 100 µL total fill volume and approximately 50 µL usable volume, these inserts are ideal for scarce or high‑value samples. Residual volume is approximately 3 µL with most autosamplers. The insert is slightly taller than standard designs and features a self‑aligning geometry that centers automatically within the vial, eliminating the need for springs while maintaining reliable positioning.
Manufactured in an ISO 9001:2015 certified facility, these inserts deliver consistent dimensional accuracy and dependable performance across batches.
