Lab Use 20mm Crimp Top GC Headspace Vial

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.

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.

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 chromatographic direct range of 20mm crimped top-space sample vials and caps are available in 20ml amber and transparent colors, 10ml and 6ml with a variety of flat-bottom and round-bottom shapes, suitable for autosamplers of many brands on the market. Our 20mm crimp cap with silicone/PTFE Septa is compatible with all autosamplers.

Aijiren Tech crimp 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 are also optional.

Why Choose Aijiren’s 20mm Crimp Top Headspace Vials
Quality – You can expect our Headspace Vials product to be of the highest quality because they must pass the most stringent Quality Assurance tests before they arrive at your door.
Reliability – You can rest assured that the Headspace Vials you purchase will reliably perform the jobs for which they are designed.

Metal caps offer the widest range of temperature tolerances and are very resistant to fracture from impact. Metal caps are great for gas chromatography applications. A metal closure is manufactured from either steel (coated with anti-corrosive coating of either chromeplate or tinplate) or aluminum.

Headspace vials have different capacity specifications, including 6ml, 10ml, 20ml, etc. Use a standard sample vial to ensure sufficient headspace. Usually, the reserved volume should be at least 50% of the sample volume.

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.

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.

The material of Headspace Vials is low extractable Borosilicate glass with low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance and high chemical stability. Headspace Vials suitable for headspace analysis of volatile solids and gases.

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.

Headspace vials can withstand the higher temperatures and internal pressures required for volatile gas analysis. The Color of headspace vials is divided into two kinds of brown and transparent, the brown vials can be protected from light, and the manufacturing process adopts the molding method, which has the characteristics of thick wall, high mechanical strength, and not easy to be broken.

Head space vials analysis of gases present in head space sample vials,Laboratory bottles for head space analysis are called head space vials.
To get accurate results,We also have certain requirements for sample bottles and septa.
Head sample space are available with round bottom and flat bottom,as follows:
The round bottom is compatible with most automatic samplers,and the sample arm is convenient for carrying the sample vials from tray.
The flat bottom can achieve a high level of heating efficiency during manual head space injection and is suitable for certain types of instruments.

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.

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.

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.
