Vials, Snap Top, Glass. Clear / Clear Insert, 300ul with Write-On Patch and fill lines, Fused Insert™. An 11mm snap ring and 12x32mm outer dimensions. For use as an autosampler vial. AQ Brand. 100/PK.
Additional Info:
The 9532C‑0CV AQ™ Brand Snap‑Top Autosampler Vial is a 300 µL clear glass vial with a Fused Insert™, designed for chromatographic applications requiring improved low‑volume recovery and consistent autosampler performance. Both the vial and insert are manufactured from first hydrolytic, Class A, Type 33 borosilicate glass, providing dependable chemical durability for routine and intermediate‑level analytical workflows.
An integrated ceramic write‑on patch and fill lines offer durable labeling and volume reference that resist smearing or scratching when exposed to common laboratory solvents. This supports clear sample identification in both routine and regulated environments.
Insert bottom depth, height, and alignment are precisely designed and QC‑controlled to support maximum recovery while protecting autosampler needles. The AQ™ Fused Insert™ is engineered to sit slightly above the vial lip, improving contact with the cap septum and enabling a more effective seal. Importantly, the insert is not fused to the vial bottom, eliminating stress‑related cracking at a fusion point and helping prevent leakage that may be observed in some competitive designs.
This vial format delivers performance comparable to QSerts™‑style fused‑insert vials, while offering a lower‑cost alternative and strong overall value.
Important Use Guidance Snap caps and snap‑top vials are not generally recommended for LC‑MS applications or other critical analyses involving volatile solvents, including aqueous systems. For these applications, screw‑thread vials with properly matched caps and septa are generally preferred to reduce solvent evaporation and maintain sample integrity.
