Types of Autosampler Vials: Glass vs. Plastic

Glass and plastic are the primary materials used for autosampler vials. Glass vials, commonly made of borosilicate or amber glass, provide high-quality sample storage and visibility. They are ideal for chromatography applications requiring inert surfaces. Plastic vials, often made of polypropylene, offer durability and are lightweight. Glass vials are preferred for MS or EPA testing due to their performance level, while plastic vials are suitable for general use. Consider the sample requirements and compatibility with your analytical instruments when choosing between glass and plastic vials.

Selecting the Right Vial for Your Application

Which Type of Glass Vial is Best for Your Application?

Autosampler vials play a crucial role in maintaining sample integrity during analytical testing. When selecting the right vial for your application, factors like compatibility with analytical instruments, sample volume, and chemical compatibility must be considered. Different vial materials such as borosilicate glass, amber glass, and plastic offer varying levels of performance. Ensure a proper fit with closures and septa to prevent any contamination. Consider the specific requirements of your analysis, whether it's for chromatography, EPA, MS, or other applications. Select the appropriate vial size, from microvials to larger capacities, to meet your experimental needs.

Compatibility with Analytical Instruments

To ensure precise results, selecting the correct autosampler vials is crucial for compatibility with various analytical instruments. Different instruments may require specific vial materials like borosilicate glass or amber glass for optimal performance. Considering factors such as closure type, septa quality, and the sample volume capacity in ml is essential. Matching the vial characteristics to the analysis method, whether it's chromatography, EPA, or MS, is necessary for reliable and accurate testing results.

Considerations for Sample Volume and Chemical Compatibility

When selecting autosampler vials, it is crucial to consider sample volume and chemical compatibility. Different applications may require varying sample volumes, necessitating a variety of sizes such as microvials or larger ml capacities. Similarly, chemical compatibility plays a pivotal role in maintaining sample integrity and accurate results. Certain analyses require specific materials like borosilicate glass for its inert properties, while others benefit from amber glass to protect light-sensitive samples. Understanding these factors ensures optimal performance levels in chromatography and other analytical techniques. Proper consideration of these aspects enhances the reliability of your results.

Best Practices for Using Autosampler Vials

How to Choose the Best Storage Vials

Ensuring Sample Integrity through Proper Vial Sealing is paramount. Tight closures prevent sample evaporation and maintain sample quality.
