crimp top hplc vial
The crimp top HPLC vial is a critical component in analytical chemistry, specifically designed for high-performance liquid chromatography applications. These precision-engineered glass containers feature a unique neck finish that accommodates an aluminum crimp cap and septum system, ensuring a reliable and contamination-free seal. Manufactured from high-quality borosilicate glass, these vials offer exceptional chemical resistance and maintain sample integrity throughout the analysis process. The standardized 12x32mm dimensions make them compatible with most modern HPLC autosampler systems. The crimp top design provides a secure closure that prevents sample evaporation and maintains internal pressure during analysis. The vials undergo rigorous quality control processes, including dimensional checks and surface treatment to minimize adsorption effects. Their transparency allows for visual inspection of sample contents, while the precision-ground bottom ensures stable positioning in autosampler trays. The vials typically feature a volume capacity of 2mL, with optional graduated marking lines for accurate sample volume measurement. The clean, inert surface of these vials minimizes the risk of sample contamination and ensures reliable analytical results.
