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.

Bonded cap and septa are designed specifically for HPLC autosamplers and have excellent resealing properties and chemical resistance, ensuring sample integrity and accuracy during storage and analysis.

The Hand Decrimper is typically designed to work with two common crimp cap sizes, which are 11mm and 20mm. These sizes correspond to the diameter of the crimp caps, indicating their compatibility with specific vial sizes. This tool is typically made of durable materials such as stainless steel or high-quality aluminum. These materials are chosen for their strength and resistance to corrosion, ensuring long-lasting performance. The decrimping features a handle, often designed with ergonomic considerations for comfortable and efficient use by laboratory personnel. The handle provides a firm grip for precise control during the decrimping process.

A 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 vial features an 11mm snap ring closure, which provides a secure and leak-proof seal. These 2ml snap autosampler vials are recommended for short-term sample storage and non-volatile samples because the seal is not as secure as a crimp or screw thread seal. 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. Compared with crimp top vials, snap vials can be capped and uncapped easily without tools, making it more convenient to use.

The 11mm crimp top autosampler vial 2ml is the most commonly used gas sampling vial on the market at present. The 11mm 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.  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. 

These headspace vials are made of superior quality 1st hydrolytic class glass (Type 1) and have a thicker glass wall to withstand higher temperatures and internal pressures for the analysis of volatile gas in the vial’s headspace.

Polypropylene is chemically resistant and the material of choice for pH sensitive samples, sodium or heavy metal analyses.
The PP vials are ideal when working with pH sensitive samples, aqueous samples in pharmaceutical applications, or undertaking sodium analysis.

Snap Cap Vials are an extension of the crimp cap system of sealing. A plastic cap is stretched over the rim of the vial to form a seal by squeezing the septum between the glass and the stretched plastic cap. Plastic has memory and wants to return to the original dimension. This tension in the cap to return to its original size is the force forming the seal between glass, cap and septum. The advantage of a plastic snap cap is no tools are required to assemble. The snap-top cap is a compromise sealing system.

Aijiren 9mm high recovery screw vial is made of borosilicate class, so it has a good Liner coefficient. In the chromatography analysis field, 9mm high recovery screw vials are widely used in Life science and technology, Environmental Protection, and Food Safety. Smooth, conical interior surfaces facilitate complete sample recovery. high recovery vials offer precision vials made from low expansion borosilicate glass and designed with a unique interior bottom, solid glass bottom of a Microliter-Vial with an inner cone, allowing for maximum retrieval of contents by a syringe. These high-quality 9mm clear glass vials are 2mL, 12x32mm, and fit most brands of autosamplers. Made of superior quality borosilicate clear, they meet all requirements of US, EU, and JPN Pharmacopia.

2ml Clear Screw HPLC Vials and closures are universally suitable on most autosamplers, convenient in handling, and available in a broad selection of different cap colors and septum materials.

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 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.

These 2ml HPLC Vials with Caps are 40% large and are designed for use in robot autosamplers, known as Agilent. So welcome your inquiry about 2ml HPLC Vials with Caps and other chromatography vials from Aijiren.

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.

11mm Crimp Top Autosampler Vial for GC and HPLC. Vials have a 40% larger opening than standard opening aluminum seal vials, manufactured of Clear or Amber borosilicate glass. The standard 12x32mm profile is compatible with 11mm aluminum seal closures. The precision-shaped bottleneck can improve the processing capacity of the autosampler. In order to ensure good function, it can be slit in advance to facilitate needle penetration, designed for single injection or short sampling cycle, and especially suitable for liquid chromatography.
