The Chromatography Vials

06/30/2022

Chromatography vials are used in a wide range of experiments and are available in many sizes, finishes, and septa materials. Some come with write-on labels, ensuring proper identification of compounds. Other vials feature a conical interior shape that enables maximum retrieval of materials. Here is an overview of what you need to know about chromatography vials and why you should choose these tools for your work.

Closures for chromatography vials should be compatible with the solvent and sample to avoid contamination or ghost peaks. A good choice is a chromatography vial with a closed-top screw closure. Its thread design is not standardized, so you should buy it from a single source. You can also buy replacement septa, which are partially available in the market. Alternatively, you can purchase pre-assembled closures and avoid manual assembly, which may lead to contamination and wrong orientation of septa.

Chromatography vials can be made of either glass or plastic materials. The latter is the most popular choice because of its lighter weight and easy handling, while the former is less expensive to manufacture. Plastic vials are light in weight, durable, and inexpensive. They can also be treated with a silicone solution to render them more opaque and resistant to heat and light. If you are considering buying chromatography vials for your experiment, consider the different materials available to ensure the best results.

For chromatography, the simplest type of achromatography vial is a glass tube. The latter type of vial can either have a flat bottom or a tube-like shape. These containers are made with a wide variety of caps and septum materials. Aside from glass, polypropylene chromatography vials are made with a silicone O-ring to prevent leakage and contamination.

A chromatography vial can be made from glass, borosilicate glass, or soda-lime. Glass is a nonporous material that is largely immune to chemicals. Glass is also recyclable and sustainable because it's made from abundant raw materials. An additional benefit of glass vials is their amber tint, which protects the substance from harmful UV light. The amber glass is ideal for light-sensitive samples.

Chromatography vials may be screw or crimp-capped. The latter allows the septum to be pressed down tightly and prevents evaporation. While screw caps are easier to open, crimp caps provide additional assurance of sealing. Click here for more information. Hence, crimp-top chromatography vials are the preferred choice for GC and MS applications. They're also faster to seal, but the latter is recommended if you're using volatile materials.

The material of the chromatography vials can also be of great importance. The glass vials from Tisch Scientific are manufactured using high-quality borosilicate glass, which has a long shelf life and low coefficient of thermal expansion, making it the ideal choice for chromatography experiments. Its smooth surface and low coefficient of thermal expansion make it perfect for chromatography. The material used to make chromatography vials is crucial in the accuracy of the analysis of different materials.
