CUSTOM ITEM: Vials, Snap Top, Glass. Amber, 1.5ml, U Shape. An 11mm snap-ring with 12x32mm outer dimensions and a fluted stand. For use as an autosampler vial. MICROSOLV Brand. 100/PK.
Additional Info:
The 9512C‑0AV‑P MICROSOLV™ Brand U‑Shape Snap‑Top Autosampler Vial is a 1.5 mL amber glass vial offered as a custom order item for laboratories that require a center‑draining U‑shaped geometry combined with light protection. These vials are produced from first hydrolytic, Class A, Type N51A borosilicate glass and amberized to reduce light exposure for photosensitive samples.
The inner U‑shaped profile promotes center‑draining behavior and delivers a typical residual volume of approximately 15 µL for most autosamplers. This geometry is commonly compared to champagne‑style vials, offering predictable recovery characteristics while maintaining compatibility with standard snap‑top autosampler formats.
A fluted base improves stability when the vial is standing alone on a benchtop or work surface. For optimal sealing and consistent performance, use of Soft‑Guard™ snap caps is recommended with this vial design.
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 evaporation and help maintain sample integrity.
