Jul 31, 2020 · Needle Gauge: A bigger needle gauge can need more force to get through non-pre-slit septa, which could cause damage to the septa or sample contamination. A pre-slit septum might be the best choice in this situation. Injection Frequency: A pre-slit septa may be more appropriate for applications requiring repeated injections since it can lessen

PTFE/silicone septa are always best. What force is required to penetrate the septum? Generally, silicone septa are more easily pierced than red rubber or butyl septa. For thicker, hard-to-pierce septa, a small gauge (23 gauge) needle may be required, or a stronger S-needle can be used. Preslit septa are the best option for

Oct 19, 2015 · The first OOS occurred when a chemist used the caps with non-cut septa on the Shimadzu HPLC. All vials had the first injections with significantly lower areas than the following injections. Prior to this OOS, we allocated the caps with non-cut septa for the Dionex HPLC, and the caps with pre-cut septa for the Shimadzu HPLC.
