Waters Qsert Vial 300 ul Screw Cap with Septa Pack of 100 Vials

The Waters 186001125C Qsert Vial is a specialized container designed for the secure handling and analysis of small-volume liquid samples in chromatography systems. This vial is a 2 ml short-thread vial with a 300 µl capacity insert pre-installed, offering the benefits of small-volume handling within the footprint of a standard autosampler vial.

A key feature is the screw cap with a septa. The cap is constructed from polypropylene and provides a secure, leak-proof seal. The septa (the sealing barrier) is crucial for analytical applications, as it allows for the needle of an autosampler to pierce through to the sample and then reseal, minimizing the risk of evaporation and contamination.

The Waters Qsert design ensures that samples are concentrated in the insert, optimizing sample usage and improving analytical sensitivity. This vial is an essential consumable for HPLC and GC laboratories performing sensitive analysis on limited sample volumes.
