hplc sample vial
The HPLC sample vial is a critical component in high-performance liquid chromatography analysis, designed to safely contain and protect analytical samples during testing processes. These precision-engineered containers are manufactured from high-quality borosilicate glass or specialized polymers, offering exceptional chemical resistance and durability. The vials feature carefully calibrated dimensions to ensure perfect compatibility with autosampler systems, typically available in standard sizes of 2mL, 4mL, and 12mL. Each vial incorporates a specialized septum and cap system that maintains sample integrity while allowing easy needle penetration for automated sampling. The design includes specific features such as write-on patches for sample identification, graduated markings for volume reference, and flat bottoms for stable positioning in sample trays. Advanced manufacturing processes ensure the internal surfaces are ultra-smooth and inert, preventing sample adhesion and contamination. The vials often incorporate UV protection properties to preserve light-sensitive compounds and feature precision threads for secure closure, maintaining sample stability throughout the analysis process.
