2mL HPLC Vials: The Future of Chromatography Sample Preparation
High-Performance Liquid Chromatography (HPLC) is a technique widely used in the pharmaceutical, biotechnology, and chemical industries for separating, identifying, and quantifying compounds in a mixture. The success of an HPLC analysis depends largely on the quality of the sample preparation, and the choice of the vial is critical in ensuring accurate and reproducible results.
Introducing 2mL HPLC vials – the future of chromatography sample preparation. These vials offer several advantages over traditional vials, making them an essential tool for any laboratory performing HPLC analysis.
Advantages of 2mL HPLC Vials:
1. Smaller Volume: The smaller volume of 2mL HPLC vials makes them ideal for analyzing trace amounts of compounds in a mixture. This is particularly useful for high-value and low-volume samples, where waste reduction is a critical concern.
2. Reduced Cost: The smaller volume of 2mL HPLC vials also results in a lower cost per analysis compared to larger vials. This makes them an economical choice for laboratories with a high number of samples to analyze.
3. Improved Sample Concentration: The smaller volume of the 2mL HPLC vials allows for higher sample concentration, leading to improved sensitivity and accuracy of the analysis.
4. Improved Reproducibility: The reduced volume of the vials minimizes the volume of solvent required, reducing the possibility of sample evaporation and ensuring accurate and reproducible results.
5. Enhanced Sample Preservation: The 2mL HPLC vials have a smaller headspace, reducing the possibility of sample oxidation and preserving the integrity of the sample over time.

Headspace vials are one of those rare laboratory supplies that are appropriately named: headspace vials are lab vials with extra space at their top (head). Simple! They’re typically used in autosampler machines in chromatography, and for that reason are sometimes called autosampler vials or chromatography vials.
Headspace vials are available in two major styles: crimp top and screw thread. GC headspace vialsCrimp top vials have a metal cap that’s closed with a handheld crimper. Neat. Screw thread vials have a simple screw cap, just like that cheap wine you keep buying. Both types employ stoppers or septa between the cap and the vial, depending on the application.
1. Vial Size
Headspace vials are available in 6, 10, and 20 ml sizes. Use a vial large enough to ensure adequate headspace or phase ratio without excessive dilution of the components of interest. The phase ratio is discussed later and should normally be at least 50 % of the sample volume.
2. Bottom Profile
Headspace vials GC headspace vialsmay be round-bottomed or flat-bottomed. Either type is suitable but round-bottomed vials tend to be stronger and may work more reliably when the autosampler moves the vials into and out of the incubator. Round-bottomed vials also tend to withstand higher pressures and are more suitable for elevated temperatures and applications such as derivatization.
3. Correct Crimping
Headspace vials must be correctly crimped. Ensure the crimper is not worn and is adjusted correctly. The cap should not turn after application to the vial. Find out more about correct vial crimping.
4. Septa Choice
Use septa suitable for the temperature of the system. Poor septa Poor septa can result in bleed and so contaminate the headspace.
5. Cleanliness of Vial
Vials should be clean. Not all vials are the same and dirty or re-washed vials can cause ghost peaks or erroneous results.

Aijiren Tech crimps top headspace vials are available in a flat or round bottom style, with clear or amber glass. Headspace closures are available in pre-assembled caps with septums or can be ordered individually. Pressure release, seal with lining, and seal with magnetic lining is also optional.
The material of Headspace Vials is low extractable Borosilicate glass with a low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. Headspace Vials are suitable for headspace analysis of volatile solids and gases.
The headspace sample vial is used for the headspace analysis, especially for the volatile samples. Generally, there are 6ml, 10ml and 20ml volume vials for selection, with round or flat bottom type. Both types are suitable for sampling, but the round bottom one is more adaptable for storing samples since it could undertake higher pressures and withstand high temperatures. The cap of the headspace sample vial must be properly and tightly pressed so that it will not affect the use of automatic instruments during the operation.
