Vials, Screw Top, Polypropylene, Translucent, 300ul, LC-MS compatible, with a marking spot, 12x32mm outer dimensions. AQ Brand. 1000/CS.
Additional Info:
The 9532S‑W‑MS‑K AQ™ brand Screw‑Top Microvial is the case‑quantity configuration (1000/CS) of the 300 µL LC‑MS compatible polypropylene vial, designed for high‑throughput and cost‑efficient laboratory operations. These microvials are molded from ultra‑virgin, specially formulated polypropylene that has been tested to deliver virtually no extractables when used with common LC‑MS solvents.
A flat‑bottom inner cone geometry distinguishes these microvials from conventional V‑bottom plastic designs. This geometry minimizes air entrapment during filling and allows autosampler needles and pipet tips to reach the true bottom of the vial, helping ensure consistent injections and improved recovery from very small sample volumes.
Each vial includes an integrated permanent marking spot that provides a durable labeling surface resistant to smearing. To support sensitive workflows, vials are supplied in ultra‑pure plastic baggies, helping maintain cleanliness prior to use.
With 9 mm screw‑top compatibility, these microvials are compatible with all MICROSOLV screw caps. For sensitive LC‑MS applications, use of AQR™ caps with ultra‑clean septa is recommended.
