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. RSA Brand. 100/PK.
Additional Info:
The 9532S‑WCV‑WT‑RS RSA™ Wide‑Tip Fused Insert Autosampler Vial is a high‑performance, low‑volume vial engineered for reliable injections where sample recovery, reproducibility, and filling consistency are critical. Both the vial body and the Wide‑Tip Fused Insert™ are manufactured from first hydrolytic, Class A, Type‑33 reduced surface activity borosilicate glass, delivering exceptional chemical inertness and lot‑to‑lot consistency.
The 300 µL fused insert is permanently integrated into the vial, providing precise geometry and eliminating variability associated with removable inserts. The wide‑tip insert design at the bottom helps prevent bubble formation during rapid or automated filling, making this vial especially well suited for high‑throughput and LC‑MS workflows.
