Chromatography vials are small glass or plastic containers that can be used for laboratory samples and medicines. They can come in different shapes and sizes and may feature a cap for an autosampler. Vials are used extensively in research laboratories, and are a critical part of the workflow. For more information, see the chromatography vial's function and advantages. Read more great facts, click this additional reading here. Here, we'll discuss some of their most common uses. Chromatography vials have different sizes for each type of sample. For a trace analysis, borosilicate glass is the most common. For other applications, polypropylene is a cheaper alternative that offers adequate protection from the pH-sensitive materials.

In either case, choosing the wrong size of chromatography vials can lead to poor reproducibility between injections and damage to the autosampler needle. Chromatography vials are available in various sizes, including small and large openings. Typical sizes for standard glass vials are 8x40mm, 15x45mm, and 12x32mm. In addition to their size, users can also choose from a standard or wide mouth opening. The size of the vial cap is important as well, so select one that suits your application needs. Lastly, the type of cap is important, as some require a certain size for robotic arm handling. Chromatography vials are used for separating inorganic and organic compounds. There are different sizes, materials, and finishes for these vials. Some even come with write-on patches for easy identification. Chromatography vials come in white, amber, and clear color. If you need more than one type of vial, it is wise to consider buying a bulk kit. However, don't forget to check the specs of your samples. When choosing a type of chromatography vial, it is essential to check the material of the septum. The septum should be compatible with the sample and solvent, or else you may have problems. Chemical interactions between the sample and solvent may result in ghost peaks and other undesirable effects. Generally, PTFE chromatography vials have good chemical resistance, but they are not very resealing. Silicone septas are more susceptible to chemical reactions, so you should consider whether you need a punctured or crimp closure. The plastic chromatography vials market is expected to grow at a CAGR of 7% during the forecast period. It is likely to be driven by the increasing need for food safety and growing importance of HPLC. However, the market for chromatography vials has been limited by strict government plastic usage norms. However, if you are looking for a plastic alternative, make sure you check the specifications. This way, you'll be sure to use them with confidence. As with all plastic components, the type of closure you choose will affect the performance of your chromatography instrument. The proper closure will depend on the type of sample you want to analyze. Silicone or PTFE closures are compatible with HPLC needles. However, if you're not sure whether or not your needles are compatible with them, you can opt for snap-ring chromatography vials. They are available individually or as part of a Vial Kit.
