chromatography vial

A chromatography vial is a specialized container designed for holding samples in analytical chemistry, particularly in chromatographic analysis. These precision-engineered vessels are essential components in both gas and liquid chromatography systems, offering reliable sample containment and protection. Manufactured from high-quality borosilicate glass or specialized polymers, chromatography vials feature carefully designed dimensions and closures to ensure compatibility with autosampler systems. The vials typically range from 2mL to 40mL in capacity, with the most common sizes being 2mL and 4mL for routine analysis. Each vial incorporates specific design elements, including precise thread patterns for caps, optimized internal geometry for maximum sample recovery, and specialized surface treatments to minimize sample interaction. The vials often feature write-on spots for sample identification and graduated markings for volume reference. Advanced versions may include amber glass construction for light-sensitive samples or silanized surfaces for enhanced chemical inertness. These vials play a crucial role in maintaining sample integrity throughout the analytical process, preventing contamination, evaporation, and degradation while ensuring accurate and reproducible results in chromatographic analysis.

Popular Products

Chromatography vials offer numerous significant advantages that make them indispensable in analytical laboratories. First, their precision-engineered design ensures perfect compatibility with automated sampling systems, reducing the risk of mechanical failures and sample loss during analysis. The high-quality materials used in their construction provide exceptional chemical resistance, preventing any unwanted interactions between the sample and container walls that could compromise analytical results. The vials' optimized internal geometry maximizes sample recovery, enabling accurate analysis even with minimal sample volumes, which is particularly valuable when working with precious or limited samples. The secure sealing system, typically featuring PTFE-lined caps, effectively prevents sample evaporation and contamination, maintaining sample integrity over extended storage periods. The standardized dimensions across manufacturers ensure universal compatibility with various analytical instruments, providing flexibility in laboratory operations. The transparent nature of the glass vials allows for visual inspection of samples before analysis, helping technicians identify any potential issues such as precipitation or phase separation. For light-sensitive samples, amber glass options provide essential protection against photodegradation. The durability of these vials makes them suitable for high-throughput environments, while their clean, contamination-free nature ensures reliable results. The availability of various closure options, including crimp caps and screw caps, allows laboratories to choose the most suitable sealing method for their specific applications. Additionally, the vials' compact size optimizes storage space while maintaining easy sample handling and identification.

Superior Sample Protection

Superior Sample Protection

Chromatography vials excel in protecting sample integrity through multiple sophisticated design features. The high-quality borosilicate glass construction provides exceptional chemical resistance, preventing any leaching or contamination that could affect analytical results. The precisely engineered sealing system, incorporating PTFE-lined caps, creates an impermeable barrier against environmental factors. This hermetic seal effectively prevents sample evaporation, moisture intrusion, and contamination from airborne particles. For light-sensitive compounds, amber glass variants offer superior protection against photodegradation by blocking harmful UV and visible light wavelengths. The inert surface properties of these vials ensure that sensitive analytes remain stable throughout storage and analysis, maintaining the accuracy of test results.
Autosampler Compatibility

Autosampler Compatibility

The precision engineering of chromatography vials ensures seamless integration with modern autosampler systems, a crucial feature for high-throughput laboratories. Each vial is manufactured to exact dimensional specifications, with carefully controlled tolerances for height, diameter, and thread pitch. This precision prevents common automation issues such as misalignment or improper sampling depth. The reinforced neck design withstands repeated punctures from autosampler needles without compromising structural integrity. The optimized bottom geometry ensures maximum sample recovery, even with minimal residual volumes, while the standardized dimensions guarantee compatibility across different instrument manufacturers.
Versatile Storage Solutions

Versatile Storage Solutions

Chromatography vials offer exceptional versatility in sample storage and handling applications. The range of available sizes, from microvolume to standard capacity, accommodates diverse analytical requirements. The vials feature specialized surface treatments that minimize analyte adsorption, ensuring sample stability during both short-term and long-term storage. The write-on patch facilitates clear sample identification, while graduated markings enable precise volume measurement. The robust construction withstands various storage conditions, including refrigeration and freezing, without compromising structural integrity. The availability of certified clean options ensures compliance with regulatory requirements in regulated environments.
