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.

New Product Releases

The crimp top HPLC vial offers numerous practical benefits that make it an essential tool in analytical laboratories. First, the crimped seal design provides superior protection against sample evaporation and contamination, ensuring the integrity of valuable samples throughout extended analysis periods. The aluminum crimp cap creates a consistent, reproducible seal that maintains internal pressure and prevents leakage, even during high-pressure applications. The borosilicate glass construction delivers exceptional chemical resistance, making these vials suitable for a wide range of solvents and sample types. Users benefit from the vials' compatibility with standard autosampler systems, enabling seamless integration into existing workflows. The transparent nature of the glass allows for easy sample visualization and volume verification. The precision-manufactured dimensions ensure consistent positioning in autosampler trays, reducing the risk of mechanical failures during analysis. The smooth, inert interior surface minimizes sample interaction with the vial walls, preventing potential loss of analytes through adsorption. These vials are cost-effective, as their robust construction allows for multiple uses when properly cleaned and handled. The standardized design accommodates various septum materials, offering flexibility in application requirements. The crimp top closure system provides audible and tactile feedback during proper sealing, helping operators ensure correct cap application. The vials' small volume design helps minimize sample waste while maintaining adequate headspace for injection procedures.

Superior Sealing Technology

Superior Sealing Technology

The crimp top HPLC vial's sealing system represents a breakthrough in sample containment technology. The aluminum crimp cap, when properly applied, creates a hermetic seal that effectively prevents sample loss through evaporation or leakage. This sealing mechanism utilizes precision-engineered crimping tools that apply uniform pressure around the vial's neck, ensuring consistent seal quality across multiple samples. The design incorporates a septum that maintains its integrity even after multiple injections, featuring self-sealing properties that prevent sample contamination. The crimp seal's reliability is particularly valuable for volatile samples or when maintaining specific headspace conditions is crucial. The system's effectiveness has been validated through extensive testing under various temperature and pressure conditions, demonstrating its capability to maintain sample integrity in demanding analytical environments.
Optimal Chemical Compatibility
