CUSTOM ITEM: Inserts, Low Volume for Vials, Glass. Clear, 250ul fill volume with a conical, precision point and 6x38mm outer dimensions. For use in 4ml autosampler vials. AQ Brand. BULK PRICING.
Additional Info:
Maximize recovery in larger vial formats with precision inserts designed for low‑volume analysis in 4 mL workflows.
9504S‑01N inserts are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass and feature a mandrel‑formed precision conical tip that concentrates sample at the bottom for maximum recovery and consistent needle access. This design provides approximately 250 µL total fill volume with about 150 µL usable volume and a residual volume near 3 µL in most autosamplers.
The extended 6 × 38 mm format is optimized specifically for 4 mL autosampler vials, allowing low‑volume sample analysis without compromising vial compatibility. The precision‑formed tip ensures consistent geometry from insert to insert, improving reproducibility across injections and methods.
Springs may be required depending on the autosampler configuration and are sold separately. When used, springs provide proper centering and alignment within 13 mm screw top 4 mL vials, helping reduce needle misalignment and minimizing the risk of insert damage during operation.
Manufactured in an ISO 9001:2015 certified facility, these inserts ensure reliable dimensional consistency and reproducible analytical performance across batches.
