Vials, screw top with phenolic open-top cap, pre-assembled

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. Amber glass vials (volume 40 mL, O.D. × H. 29 mm × 82 mm) are useful in preventing the sensitive analyte under investigation from exposure to UV light. The threads on the standard vials are 24-400. The phenolic cap is autoclavable and it can withstand the temperature up to 149° C. The tan PTFE/silicone septum is sized to fit screw top vials. It is suitable for use with most organics (until pierced) and is not recommended for use with chlorosilanes.
