These A-Line certified vials are constructed from Type 1 borosilicate glass, with low metal content, to protect samples from destabilizing or leaching. They are designed to provide the ultimate solution for handling precious samples.

• Maximum inertness delivers reduced analyte peak variability for utmost confidence in your results
• Consistent vial-to-vial and lot-to-lot performance means less time troubleshooting and rerunning samples
• Designed to fit a range of caps, including 9 mm screw caps, 12 mm snap caps and 11 mm crimp caps for easier inventory management
• Septa are continually being improved to limit leaching, coring, sticking, push-through, hardness, and adsorption/absorption

The associated 9 mm screw caps are available with septa constructed from either PTFE/silicone or natural red rubber. The A-line certified vials (screw vials, crimp vials and snap vials) and certified caps (screw caps, crimp caps and snap caps) are the perfect fit for HPLC and GC instrument platforms across a wide variety of applications, including pharmaceutical, environmental, energy and fuels, forensics, materials science, biopharmaceutical, proteomics, and metabolomics.
