Our screw vials and vial screw caps are designed for both HPLC and GC instrument platforms across a wide variety of applications, including pharmaceutical, environmental, energy and fuels, forensics, materials science, biopharmaceutical, proteomics, and metabolomics. The 2 mL screw top vial is recommended for sample matrix that is not too volatile.

Jun 13, 2022 · Of course, it is applicable in most HPLC and GC operations. They work well for applications where ease of needle penetration is essential. In addition, septa-silica gel has strong repetitive sealability. It can maintain good close performance even after multiple injections in the vial. PTFE is a material with better chemical compatibility.
