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.

And this sample vial is extremely compatible.The 1.5ml sample vial we usually say is the 2ml volume sample vial.

Chromatography septas can be pre-slit. A pre-slit septum is an ideal choice in applications requiring 20% or more of the sample injection each time from the vial so that suction is avoided. The slit allows ambient gas to equalize the gas in the vial so that a vacuum is not created in the vial from the tight seal around the needle. If coring or clogging from a narrow needle or needle deflection from highly durable septa material is a concern, then choosing a pre-slit septum is a better choice.
A PTFE/Silicone with a slitted septum allows for easier needle penetration as well as to release the vacuum that forms when a large volume of sample is withdrawn from a vial. This septum provides chromatographic characteristics similar to that of a septum without a slit except that the ability to withstand exposure to aggressive solvents is slightly lessened. Pre-slit septa are highly recommended for improving injection-to-injection reproducibility with autosamplers withdrawing greater than 50µL of sample from a 2mL vial, due to possible cavitation (vacuum).

The 9mm screw vials are made of transparent Type 1 Class A or amber Type 1 Class B borosate glass. The 9mm screw vials are forged at high temperatures from borosilicate glass.

Caps for screw thread vials are available with either an open hole for autosampler use and standard addition or with a solid top for sample storage. Teflon and silicone rubber or ultra-pure silicone are used as raw materials to ensure that the septa are non-toxic; to ensure excellent functions, it is particularly suitable for gas chromatography, and to ensure that the septum does not fall into the sample vial during the injection process.
The adhesive-free bonding process is used to combine the polytetrafluoroethylene membrane and the silicon rubber or silicone bond together to maintain the excellent characteristics of the two materials. The polytetrafluoroethylene layer of the composite septum is in contact with the reagent. It is chemically inert and resistant to acid, alkali, temperature, and adhesion. It does not work with concentrated acid, concentrated alkali, or strong oxidants even at high temperatures. At the same time, the elasticity of silicone rubber or silicone layer can ensure sealing performance.

The vial has an outer diameter of 9mm and is designed especially for use with Agilent’s and other rotating or robotic arm samplers. The vial features a short thread design with threads on the neck of the vial. This design allows for a secure and reliable closure when used with compatible screw caps or septa. Caps are made of high-quality polypropylene to exact manufacturing tolerances and lined in a controlled manufacturing environment. Available cap colors include yellow, red, green, and blue. Our septa use only the highest quality PTFE and silicone to ensure proper function and can be pre-slit to ease needle penetration. Designed for single injection and/or short sample cycles, particularly for LC applications. The absence of an elastomer layer reduces the potential for contamination.

Aijiren 2 mL crimp top vials are our recommended vials for gas chromatography applications. The crimp top vials are the best option for customers concerned with evaporation of their volatile samples, as the crimp seal significantly reduces the opportunity for evaporation. Crimp vials are also used for samples in which chain-of-custody or tamper-proof closures are required. 2 mL crimp top vials are manufactured from type 1 borosilicate glass. The high-quality material has very low metal content to help avoid sample deterioration or leaching. Precisely shaped bottlenecks increase autosampler throughput. Made of PTFE/silicone fusion, this septum has excellent inertness and can be used for multiple injections.

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.

Pre-slit PTFE/Silicone Septa is designed for applications where larger sample volumes need to be injected from a vial to avoid aspiration. This septa allows ambient gas to balance the gas in the vial, reducing the vacuum created by a tight seal around the needle. The pre-slit design makes the septa easier to penetrate with a needle and releases the vacuum created when removing large samples from the vial, while maintaining chromatographic properties similar to un-slit septa.

The 2ml chromatography vial is forged at high temperatures from borosilicate glass. The Aijiren Scientific 2ml chromatography vial Certified Vial Convenience Kit (Opening 9mm) is fully lot tested in multiple ways for 15 critical parameters.

Headspace vials are designed to withstand high internal pressure, therefore all Aijiren brand headspace vials have a wall thickness of 1.2mm for added safety, thus it is assured that the vial will not burst.
