These HPLC and GC vials are available as snap, screw or crimp in style, 15uL to 20 mL in sample size, and various of low bleed and high-quality material composition. For GC, GC/MS applications where sample matrices contain volatile or semi-volatile analytes of interest, the most common choice are crimp style vials to limit sample contents from leaking from the vial/closure
