Chromatography is a pivotal analytical technique popular across scientific disciplines for precise sample analysis. The accuracy of results relies heavily on maintaining sample integrity, making proper vial storage crucial.

In this blog, we will learn how to properly store chromatography vials.

Step 1: Pick the Right Vial

The first step in maintaining sample integrity is selecting the right chromatography vial from a chromatography vial supplier in USA. To minimize sample interaction with the container, you can choose borosilicate glass or inert plastic. Choosing the appropriate vial is important for establishing a reliable storage system.

Step 2: Cleanliness is the Key

After choosing the right glass or plastic vial, ensure the vials and caps are properly cleaned before storing samples. Dirt or dust particles can contaminate the integrity of the sample. So, before using them, it is best to wash the vials and caps with a suitable cleaning solution, followed by rinsing with a high-purity solvent to remove the tiniest amount of impurities.

Step 3: Proper Sealing

Maintaining an air-tight seal is of utmost importance to prevent the ingress of air and moisture, which can adversely affect sample stability.

Step 4: Temperature Control 

Proper temperature control is essential for sample stability. That means storing the chromatography vials from standard storage vial suppliers in a cold, regulated environment to slow reactions and prevent degradation. Also, avoid any sudden temperature changes to prevent breakage and keep storage areas dry to protect sample integrity.

Step 5: Protection from Light

Exposure to light can have adverse effects on samples, especially light-sensitive samples. If the samples are light-sensitive, consider using amber or coloured vials to protect the samples from light. Storing samples in dark or opaque containers provides an additional layer of protection against potential degradation and ensures the stability of light-sensitive samples.

Step 6: Organization and Labeling 

Lastly, maintaining a systemic approach to organizing stored chromatography vials is important for easy retrieval and tracking. Clear labelling with sample details enhances traceability and efficiency. Proper storage safeguards sample integrity, improving the accuracy and reliability of chromatographic analysis.

In the end, properly storing chromatography vials is essential for maintaining sample purity and ensuring accurate analysis. So, it is important to follow the best practices in vial storage that ultimately contribute to the success of chromatographic experiments.
