Posted by Ainsley Aiken on October 31st, 2018

Have you heard of a popular laboratory method used to segregate the mixtures of coloured substances? If yes then you should know that it is known as chromatography. It is a physical process which actually disparate the mixture between two stages called the mobile phase where the fluid moves in a particular direction and the other is called the stationary phase. Basically, you all have seen chromatography in real life like the ones used in dyes, ink, or the colouring substances used in food items.  Therefore today the topic of discussion is on the chromatography products like vials and how to choose them.

• Size of the chromatography vials:

Before understanding the chromatography vials you have to know that vials are mostly used for liquid and gas chromatography purpose. It is noteworthy that the vials are available in different sizes and shapes. Like for the liquid chromatography dimensions like the 15 x 45 mm and the 12 x 32 mm vials are used. On the other hand, some of the manufacturers also produce sizes like 1.8ml vial or the 1.2 or 2.0 ml vial.

• Closure of the vials:

Once you see that vials are available in different types of closures like the screw, snap or crimp. Again it depends on the manufacturer which type they will produce but majorly the screw types are in demand. Basically, the screw type closure is designed keeping in mind the external diameter of the chromatography vials.  Now coming to the available sizes of the crew type vials it varies from 9mm to 10mm. However, 9mm is the most commonly used size of the vials.

• Vial cap liner:

The next important thing that you have to know is about that the cap liner of the vials which is either made of rubber or from the silicone. In fact, the cap liners that are particularly used for the cramp seals are usually crafted from rubber or the plastic. While choosing the vial to make sure that it turns out congenial to the type of solvent you are using. For further selection, go through slit types like whether it is cross slit or pre-slit or single slit as well.

Where should you knock to get the chromatography supplies?

Do you need chromatography supplies like the vials then you have to be on the site http://catalog.lsdcorp.com/category/chromatography-products? Here you will see different arrays of vials available in different colour finishes with wide closure options. In fact, you will also get septum’s which are produced for auto sampler vials. In addition to that, you should also give a look through the plastic and glass inserts along with bottom and top spring. Therefore you need to explore the site to know more about the packages offered.
