gc vials

Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. A headspace vial is used in the process of top–gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.
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.
Aijiren Tech headspace vials are manufactured to provide uniform glass thickness which ensures even heat distribution for consistent sampling reliability. All Aijiren Tech headspace vials meet or exceed the OEM instrument manufacturer’s specifications. Aijiren Tech vials are available in 6ml, 10ml, and 20ml versions with Screw and Crimp types.

The 20mm 20ml Crimp Top Headspace vial has a 20mm outer diameter, which is the standard size for crimp-style headspace vials. The 20ml capacity refers to the volume of the vial, meaning it can hold up to 20 milliliters of liquid or gas sample. These vials are typically made from high-quality borosilicate glass. Borosilicate glass is chosen because it is resistant to chemical reactions and can withstand high temperatures, making it ideal for containing volatile samples without contamination. A headspace vial is used in the process of top – gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial.

The 1.5mL 9mm Short Thread Vial ND9,with its 9mm short thread design and capacity of 1.5-2.0mL, this vial makes for easy handling and integration into autosamplers. Ideal for applications requiring limited quantities. The vial comes equipped with various finishes and closure options, such as screw caps and snap caps, so researchers can select their ideal choice according to their unique research needs.

11mm crimp top chromatography vial for sale is made of type I or borosilicate glass. This chromatography vial is better seal than screw top vial and snap top vial. Aijiren produce all the chromatography vials and septa in Class 100000 Cleanroom.
The 11mm crimp top autosampler vial 2ml is the most commonly used gas sampling vial on the market at present. 2ml volume sample vial especially suitable for laboratory use.At the same time, some vial bottoms are designed with round bottoms, so that it has a flat bottoming function and compatibility with automatic sampling equipment.

1.5ml Snap Top Vials ND11, wide opening hplc vial with matched PE Snap Top Seals ND11, PTFE/rubber septa & Micro-Insert.Vials with integrated Micro-Insert are available .Vials have a 40% larger opening than standard aluminum seal vials for easier sample filling and to reduce the chance of bent or broken needles during sampling.
2ml snap autosampler vial is widely used in HPLC applications and can be used almost as universal sample vials for autosamplers, including sample vials with automatic operation. 

The vials are Specification Certified to ensure autosampler compatible physical dimensions and meet all requirements of US, EU, and JPN Pharmacopia.

Aijiren 10mL certified screw and crimp style, clear or amber glass headspace vials. These 10ml Headspace GC Vials come in both flat- and round bottom styles for use in a wide variety of headspace instrument platforms.

Crimp Vials squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The septum stays seated during piercing by the autosampler needle. The crimp cap vial requires crimping tools to carry out the sealing process. For low volume settings, manual crimper tools are the choice. For high volume settings, automated crimpers are available.
