Vials, Screw Top, Glass. Clear / Clear Insert, 300ul with Write-On Patch and fill lines, Wide Tip Fused Insert™, 9-425mm threads, 12x32mm outer dimensions. For use as an autosampler vial. AQ Brand. 100/PK.
Additional Info:
The 9532S‑WCV‑WT AQ™ Wide‑Tip Fused Insert Autosampler Vial is a reliable, low‑volume vial designed for laboratories requiring consistent recovery, ease of filling, and excellent autosampler compatibility. Both the vial and the Wide‑Tip Fused Insert™ are manufactured from first hydrolytic, Class A, Type‑33 clear borosilicate glass, providing dependable chemical performance and optical clarity.
The 300 µL fused insert is permanently integrated into the vial, eliminating variability associated with removable inserts. The wide‑tip insert geometry at the bottom helps reduce bubble formation during rapid or automated filling, supporting consistent sample preparation in high‑throughput environments.
With a typical residual volume as low as ~4 µL for many autosamplers and needle configurations, this vial delivers excellent recovery while maintaining standard screw‑top compatibility.
