Vials, Screw Top, Polypropylene, Translucent, 300ul, LC-MS compatible, with a marking spot, 12x32mm outer dimensions. AQ Brand. 100/PK.
Additional Info:
The 9532S‑W‑MS AQ™ Screw‑Top Microvial is a 300 µL polypropylene autosampler vial engineered specifically for LC‑MS workflows where low extractables, reliable needle access, and precise handling of small volumes are essential. These vials are molded from ultra‑virgin, specially formulated polypropylene, tested to deliver virtually no extractables when used with common LC‑MS solvents.
Unlike conventional plastic microvials that use a deep V‑shaped bottom, this vial features a flat‑bottom inner cone geometry. This design minimizes air entrapment during filling and allows autosampler needles and pipet tips to reach the true bottom of the vial, maximizing usable sample volume and improving injection consistency across different autosampler platforms.
An integrated permanent marking spot provides a durable labeling surface that resists smearing, offering more reliability than standard plastic vial surfaces. Each vial is packaged in ultra‑pure plastic baggies to help maintain cleanliness and reduce the risk of contamination before use.
With 9 mm screw‑top compatibility, these microvials work with all MICROSOLV screw caps. For highly sensitive LC‑MS applications, use of AQR™ caps with ultra‑clean septa is recommended.
