Inserts, Low Volume for Vials, Glass. Clear, 300ul fill volume with a conical, precision point and 6x29mm outer dimensions with plastic springs attached. For use in 2ml autosampler vials. AQ Brand. 100/PK.
Additional Info:
Reliable, cost‑effective low volume inserts designed for consistent performance in routine analytical workflows.
9502S‑02N inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass, providing excellent chemical resistance and dependable performance for standard HPLC and LC‑MS applications. This construction ensures consistent quality and durability while maintaining an economical price point.
Each insert features a mandrel‑formed, precision conical tip that concentrates sample at the bottom for improved recovery and reproducibility. Residual volume is approximately 2.5 µL with most autosamplers, with about 200 µL usable volume. Polypropylene springs are attached to keep the insert properly centered within the vial, reducing the risk of needle contact and insert breakage during operation.
Bottom depths, heights, and internal geometries are carefully controlled to support consistent needle alignment and reliable injection performance. Manufactured in an ISO 9001:2015 certified facility, these inserts provide dependable quality for routine laboratory use.
