General purpose Blue GC Septa

We offer general purpose blue GC septa that are economical and suitable for use in many applications. While they do not have the low-bleed quality or plasma coating of the premium GC septa they do hold up well at up to 275°C and provide lower bleed levels than many low-end or generic GC septa.
