CUSTOM ITEM: Inserts, Low Volume for Vials, Glass. Clear, 700ul fill volume with a conical, precision point and 8x40mm outer dimensions with plastic spring attached. For use in 4ml autosampler vials. AQ Brand. BULK PRICING.
Additional Info:
Handle larger low‑volume samples with precision and consistent recovery using inserts designed for 4 mL vial workflows.
9504S‑03N inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and designed specifically for use in 4 mL autosampler vials. The precision conical tip ensures efficient sample concentration for improved recovery and consistent needle access, even in larger volume applications.
These inserts provide a 700 µL total fill volume with approximately 500 µL usable volume and a residual volume near 8 µL with most autosamplers. The geometry is optimized to support reliable injection performance while minimizing sample loss in higher volume analytical workflows.
Polypropylene springs keep the insert centered within the vial, reducing the risk of needle misalignment and helping prevent insert breakage. Manufactured in an ISO 9001:2015 certified facility, these inserts offer consistent quality and dimensional control for reproducible results.
