When separating organic and inorganic compounds for analysis, chromatography vial closures protect compound mixtures from contamination. The caps feature different finishes and septa materials for gas or high performance liquid chromatography applications. Maintain a clean and safe workplace using the spill-free chromatography vial closures available in various sizes and styles to be compatible with autosampler operation. Identification errors made when working with unlabeled bottles are eliminated by the different color cap options.
