60 Day 100% money back guarantee. Precision Hamilton 81265 gastight syringe delivers accurate 500 µL volumes for HPLC, GC or micro‑dispensing tasks. The PTFE‑tipped plunger glides smoothly in the glass barrel while maintaining a leak‑free seal. A 22 G, 2‑inch stainless removable needle (1750 RN) allows quick swaps and minimal dead volume. Unit shows light cosmetic wear from normal lab use but is free of cracks and verified to hold vacuum at full stroke. Ideal as a spare syringe for autosamplers or manual injections when downtime is not an option. Ships next business day from Carol Stream, IL in a rigid tube to protect the needle.
