Vials are suitable basically to inject samples from an autosampler. They are available in various sizes, although 2 mL vials are more commonly used. Autosampler needle pierces through the cap during injection and withdraws the required aliquots of sample from the vials. Screw top vials (volume 2 mL, clear glass, O.D. × H. 12 mm × 32 mm) are used on many autosamplers with a standard opening of 4.6 mm. The threads on the standard vials are 8-425. The phenolic cap is equipped with aluminum liner which can withstand the temperature up to 135° C and is not autoclavable.
