injection methods. PTFE septa are rarely used for GC applications. Polyethylene (PE) Septa and Integral Molded Closures Chemically resistant polyethylene septa are usually molded into single-piece caps. The surface for needle penetration is 0.01" thick, allowing for use with most HPLC autosamplers. Polyethylene septa are not resealable and are

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
