2ml Autosampler HPLC Screw glass vials are small containers used in high-performance liquid chromatography (HPLC) analysis. They are designed specifically for use in autosamplers, which are instruments used to inject samples into the HPLC system automatically.
These vials are made of high-quality glass that is resistant to the solvents and chemicals commonly used in HPLC analysis. The vials have a capacity of 5 milliliters, which is the maximum volume of sample they can hold. The vials are typically clear or amber in color, with clear vials allowing for visual inspection of the sample, while amber vials provide protection against light-sensitive samples.
