In chromatography, sample vials are a critical part of the workflow. From laboratory to pharmaceutical applications, vials are used to store chemicals, samples, and medicines securely. Vials also protect the contents from leaching and adsorption. Selecting the right vial for chromatography is critical for ensuring robust results and efficient production. Here are some things to consider before choosing a vial:

 

First, determine the compound's stability and volatility. These two factors determine the right vial size. Secondly, consider the autosampler's design. Different injectors are designed to draw fluids from one vial while others draw from the other. Also, keep in mind the size of the autosampler's needles. Make sure that your vials match the manufacturer's requirements. You can find affordable glass and plasitic vials on this website.

 

Quality glass vials will allow you to obtain accurate results. The glass in a vial is often impure, carrying inorganic particles that can negatively impact the analytical results. Moreover, the contaminant particles will enter the sample stream, affecting quantitation values. Moreover, these particles will accumulate on the column and interfere with data integration. Lastly, glass vials are durable. They can withstand up to 500°F and can withstand high amounts of heat. That's why many laboratories prefer to use glass bottles for chromatography.

 

Whether you use glass or polyethylene for chromatography depends on your sample. Glass is recyclable and environmentally friendly due to its abundance of raw materials. Glass is more heat-resistant than plastic. However, glass is the preferred choice in many laboratories that perform sensitive chromatography. Polyethylene, meanwhile, is a popular option because of its durability and resistance to acids and bases. Most glass vials are autoclavable. Chrom Tech is the top rated vials suppliers i the region.

 

When selecting the correct chromatography vials, you need to take into consideration the following factors: size, shape, and material. You may find that glass and plastic are suitable for chromatography, but it is not essential. Plastic vials are lighter and easier to handle. They also tend to be more affordable than glass. Just be careful that you do not get fooled by cheap plastic vials.

 

In addition to size, the quality of chromatography vials can affect your results. Choose crimp chromatography vials for use with Agilent autosamplers, while 10 mm screw-cap vials won't fit in the same instrument. By choosing the right size, you can minimize the chance of problems during analysis. But be sure to select an appropriate cap for your vial.

 

Apart from size, chromography vials come in different materials. Soda-lime glass is the cheapest, while borosilicate glass is the most expensive. USP categorizes glass containers into three categories: Type I, Type II, and III. Type 1 glass is the highest-quality glass vial material and has at least 5% of boric oxide. Its low coefficient of thermal expansion makes it ideal for chromatography.

 

Apart from size, chromatography vials have other features. Choosing the correct type can also protect your samples from contamination and mechanical damage. Therefore, it is essential to know the specifications of each type before you buy. You may want to read the manual of your autosampler before you make your final purchase. If you need to buy a vial, make sure to select a crimp one. You can get more enlightened on this topic by reading here: https://www.encyclopedia.com/science-and-technology/chemistry/chemistry-general/chromatography.
