Chromatography Vials
Chromatography vials come in many shapes and sizes. Standard sizes include 12x32mm (2mL), 15x45mm (4mL), and 8x40mm (1mL). In addition to the size, users can choose whether the vials will have a crimp cap or a normal mouth opening. A limited volume vial is a small glass or plastic vial with an attached or removable insert.
The Performance Level 2 and Performance Level 3 chromatography vials are suitable for applications with higher sensitivity methods. The sensitivity of the sample is maintained. They are available in a variety of colors, with PTFE-faced and clear borosilicate glass options. They are ideal for difficult samples and high throughput. All types of chromatography vials are available in replacement caps. They are also available in bulk or inconvenience kits.
Chromatography vials should have a pre-slit septum to minimize carryover from one vial to another. Pre-slit septas are recommended for applications requiring at least 20 percent sample injection. Browse here for more details. This design allows ambient gas to equalize the pressure in the vial and prevents a vacuum from forming inside the vial. Alternatively, a non-pre-slit septum should be used for sample storage.
In addition to borosilicate glass, chromatography vials may also contain a polypropylene insert. Both types of inserts help improve the reproducibility between injections. The wrong size can result in poor sample recovery, damage to autosampler needle, and ineffective seal between the septum and vial. So, choose the appropriate size for your sample. The size of the insert will depend on the depth of the sample in the vial.
Plastic vials are a popular choice for chromatography vials. The most common plastic for chromatography vials is polypropylene, which is also common for Tic Tacs lids and recyclable containers. The material is lightweight, translucent, and heat resistant, making it a great choice for chromatography experiments. If you're not sure about the type of plastic you need, you can always check the specifications of each model.
Chromatography vials typically have screw-top, crimp-top, and snap-top closures. The latter is recommended for GC/MS analysis, while the former is suitable for HPLC and LC MS applications. Read about this service here. However, personal preference plays a large part in the choice of chromatography vials. A Snap Cap is quick to seal, but the seal is not as tight as a crimp vial. Both have advantages and disadvantages, and it depends on your purpose.
A general-purpose sample is best stored in a vial with a flat bottom. However, some samples require conical bottoms. This will help in maximizing sample recovery. For such applications, a borosilicate glass or polypropylene vial may be appropriate. However, it is worth noting that glass and polypropylene vials are also economical options. Most of these types of vials contain 20 milliliters of liquid scintillation liquid.
A chromatography vial is a handy little container for storing chemical samples. Often used in GC and HPLC, chromatography vials are essential for quality control and forensic analysis. A glass vial can be used to store liquids for analyses of chemicals in a laboratory. The crimp neck and wide opening help isolate the concentration of chemical substances and prevent contamination. They are also used in the pharmaceutical industry for various activities. Get more enlightened about the article by reading this resource: https://en.wikipedia.org/wiki/Chromatography.
