A-Line Vials

A-Line screw top vial, 2 mL, amber, write-on spot, 100/pk. These wide-opening 2 mL screw top vials come as a 100/pk and are made from amber glass composed of 5% borosilicate material rated as Type 1 Class for superior hydrolytic, acid and alkali resistance from a chemical perspective while also offering minimum thermal expansion and shock from a mechanical perspective; in addition, these vials have been manufactured and tested to meet USP 660 requirements for additional inertness. These vials also come with the additional feature of a white ceramic write-on spot which allows the user to mark their samples with the appropriate market for better identification in place of a sticker. This is in addition to the default graduation markings. This crimp style of vial is used where screw or snap top styles are not appropriate based on the sample matrix and/or operating conditions of the analytical workflow. Screw top vials are also suited for a broad range of applications, however, is one of the main choices for LC and LCMS applications where the sample is less volatile and/or were snap or crimp style vials are not appropriate. Amber glass is used when the sample matrix is sensitive to light. Screw top style vials tend to be more expensive due to their thread design when compared to crimp or snap top vials.
