hplc vial with cap and septa
HPLC vials with caps and septa are essential components in high-performance liquid chromatography analysis, designed to ensure sample integrity and accurate results. These precisely engineered containers feature a glass vial, a protective cap, and a specialized septum that creates an airtight seal while allowing needle penetration for sample extraction. The vials are typically manufactured from high-quality borosilicate glass, offering excellent chemical resistance and minimal sample interaction. The caps are designed with threading or snap-on mechanisms to provide secure closure, while the septa are made from various materials such as PTFE, silicone, or rubber compounds to maintain sample purity. Available in different sizes, commonly 2mL, these vials accommodate various sample volumes and autosampler requirements. The design ensures zero leakage, prevents contamination, and maintains sample stability during storage and analysis. Advanced features may include write-on spots for sample identification, graduation marks for volume reference, and specialized coatings for light-sensitive samples. These vials are compatible with most HPLC systems and autosamplers, making them indispensable tools in analytical laboratories, pharmaceutical research, environmental testing, and quality control applications.
