The BASIK Brand™ of crimp caps are made with Silicone Rubber/PTFE septa and are
designed for better sealing and resealing when used with snap or crimp top vials
for chromatography. Available in 5 cap colors for easy identification, these aluminum

crimp seal provides greatest assurance of no gas exchange or leakage before injection.

(even in GC), better sealing and less stress on your instrument.
