6-20ml Crimp Top Headspace Vials for GC

The Aijiren  Crimp vials are the standard vials for GC and HPLC. The crimp caps provide the tightest seal, reducing the chance of sample evaporation. The crimp vials and 20mm Aluminium crimp caps are economical, save your cost, and are easy to use with crimping tools.

The 20mm Crimp Cap is often used with Headspace Vial. It is tightly sealed and suitable for long-term storage of samples. The cap with center hole can be cut by septa, which is convenient for automatic sampling needle sampling.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. With very low metal content, extractables and leachables, top headspace vials meet high standards to meet your regulatory requirements.

The butyl septa on the PTFE surface can be used in the headspace sample bottle to evaluate the injection activity and the penetration efficiency of methyl bromide on the activated carbon. The septum can be used to seal the vial during liquid sample collection for unmodified benzene analysis using HPLC method

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.

Aijiren, as a supplier of chromatography consumables, provides headspace vials and sealing plugs. Aijiren s headspace vials and caps are carefully designed to prevent sample contamination and ensure accurate analysis. They come in various sizes and glass types. Optional crimping or threaded vials.

All 20mm Headspace Crimp Vials may appear to be created equal, but quality and performance make the difference when analyzing vital samples. Aijiren 20mm Headspace Crimp Vials are cleaned and packaged in a certified Class 10,000 clean room according to a designed process, developed to eliminate chromatographic errors associated with vials.

Headspace vials are a type of laboratory vials used for gas chromatography. They are designed to contain samples that will be analyzed using headspace gas chromatography, a technique used to analyze volatile compounds in solid or liquid samples. The vials are sealed with a septum cap, allowing the headspace above the sample to be analyzed without exposing the sample to the atmosphere. This technique is commonly used in pharmaceutical, environmental, and food analysis, among other fields.
Headspace vials, also known as gas chromatography (GC) vials or sample vials, are specialized containers used for the analysis of volatile compounds in gas chromatography. They are designed to store samples and create a headspace above the sample, which contains the volatile components to be analyzed.

Aijiren’s Headspace Caps often use metal material aluminum, which is soft and convenient for Hand Crimper and Decrimper for sealing. Not only that, the Septa produced by Aijiren is also made of high-quality silicone and ptfe, and is pressed with an exclusive process. This kind of septa is not easy to deform, break, and fall off, and it can also ensure the tightness of the vial.

Aijiren Headspace Vials feature rounded shoulders and bottoms, allowing for even heating and safer operation at higher pressures. The newly designed top provides a tighter seal with your septa. Vials are manufactured from Type I borosilicate glass and accept 20 mm aluminum seals.

The Crimpe Top headspace vials produced by Aijiren are usually made of Aluminum. A special model is SBC201202, which uses double-sided Septa made of PTFE/Silicone and Crimp Top blue Magnetic Aluminum Cap with 8mm center hole.

The Crimp Top headspace vials are made of borosilicate hydrochloric acid. It has a transparent and amber color and can withstand a temperature range of -60 to 200 degrees Celsius. Generally speaking, the volume of the headspace vial is 10-20ml, and the characteristic is 22.5*46/75mm. The performance is acid resistance, alkali resistance and high temperature resistance. Packaging usually adopts inner packaging shrink plastic box.

Aijiren Tech’s headspace vials are manufactured to provide uniform glass thickness, thereby ensuring uniform heat distribution, thereby achieving consistent sampling reliability.

20mm crimp-top headspace vials are a type of laboratory vials commonly used in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) applications.
These vials are specifically designed for the analysis of volatile compounds in samples.
Headspace analysis is used when analyzing volatile or semi-volatile compounds that can be released from a solid or liquid sample into the gas phase.
This technique is particularly useful for samples that would be difficult to directly inject into a GC system or when analyzing volatile compounds in complex matrices.

Aijiren Tech Headspace Vials are available as screw or crimp neck vials with flat or round bottoms, 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.

Headspace Vials and Closures from Aijiren. Aijiren Technologies headspace vials and closures are engineered to prevent sample contamination and ensure accurate analysis. They are available in a range of sizes and glass types. Choice of crimp or screw top vials; Bevelled top for maximum level of seal security.

Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.

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.

Crimp Caps squeeze the septum between the rim of the glass vial and the crimped aluminum cap. This forms an excellent seal preventing evaporation. The crimp cap vial requires crimping tools to carry out the sealing process.

The round-bottomed headspace vial distributes the internal pressure generated at high temperatures on the entire glass surface, and the beveled edge has a firm edge that can be pressed into the septum to achieve a more effective seal. The flat-bottomed sample bottle has a long neck and is suitable for use with headspace automatic sampling instruments
