A-Line screw top vial, 2 mL, clear, write-on spot, 100/pk. These wide-opening 2 mL screw top vials come as a 100/pk and are made from clear 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. It is one of the main choices for LC and LC/MS applications where the sample is less volatile. Screw top style vials tend to be more expensive due to their thread design when compared to crimp or snap top vials.

Screw top vials are also suited for a broad range of applications. It is one of the main choices for LC and LC/MS applications where the sample is less volatile. 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.

A-Line crimp top vial, 2 mL, clear, with write-on spot, 100/pk. These wide-opening 2 mL crimp top vials come as a 100/pk and are made from clear 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 additonal feature of a white cermanic write-on spot which allows the user to mark their samples with the appropriate makrte for better identication 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. Crimp top vials are also suited for a broad range of applications. It is one of the main choices for GC and GC/MS applications, where the sample is more volatile. Crimp top style vials tend to be more economical due to their simpler design when compared to screw top versions.

Screw cap, bonded blue PTFE/silicone septa, 100/pk. These 9 mm blue screw caps come in packs of 100 and include a bonded septum made from white PTFE/white silicone septum bi-layer. This combination is suited for a broad range of applications. It is one of the main choices for HPLC applications where the sample is less volatile. This particular version is the most widely used design for 2 mL vials. Each is compatible with all wide-opening 2 mL glass and polypropylene vials, 2 mL micro vials and 2 mL High Recovery vials. These screw caps are bonded, so offer a more secure seal than press-fit caps due to the electrostatic bonding procedure used to adhere the cap to the septum.
