Aijiren's 2 mL crimp vials and 11 mm crimp vial caps are the perfect fit for HPLC and GC autosamplers across a wide variety of applications, including pharmaceutical, environmental, energy and fuels, forensics, materials science, biopharmaceutical, proteomics, and metabolomics. The 2 mL crimp cap vial is especially powerful with GC, GC/MS applications because it limits sample content leakage from the vial/closure combination.
