A good HPLC vial should be compatible with the solvents used in the chromatography process, have low extractable/leachable levels, and consistent manufacturing quality

If you're working in the field of chromatography, then you're no stranger to the importance of choosing the right equipment. One such critical piece of equipment is the 2ml chromatography vial. Here are answers to some of the most commonly asked questions about 2ml chromatography vials.

2ml HPLC sample vials are the most commonly used vials in HPLC analysis due to their compatibility with most autosamplers and the large range of options availab...

Part No: V917 9mm clear vials are small containers that can be used to store and transport various materials, such as liquid samples, powders, and small parts.

However, even though both types of crimp and screw vials have a good seal, crimp vials provide an additional guarantee of sealing for food, forensics, and other applications for which you want to avoid sample tampering. A crimping sealing is also recommended for the storage of volatile compounds.

Headspace analysis is particularly sensitive to the quality of the sealing system used to contain the sample. The high pressures and high temperatures in use require high-performance and reproducible seals. Newer analyzers coming on the market continue to push the envelope on these requirements [See, the Shimadzu HS-20, the Agilent 7697A (See Configuration with Tray), and the Thermo Scientific TriPlus for examples of headspace samplers with oven temperatures up to 300°C]. At higher temperatures, high-quality seals are a condition for reproducible analysis free of siloxane contamination.

Septa, caps and liners play a key role in the storage and preparation of samples. They securely seal samples from the external environment while simultaneously allowing injection by sampling needles. Aijiren cap septa offers new septum materials and unique processes to improve septum sealing integrity and reduce the risk of sample contamination.
