Aijiren Tech crimps 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 is also optional.

According to different materials, it can be divided into two types, one is domestic borosilicate, and the other is imported first-grade hydrolyzed glass to meet different levels of customer needs.
The optional capacity is 10ml 20ml, the specifications are: 22.5*46mm, 22.5*75mm, and two colorless and brown headspace vials are provided.

Headspace vial manufactured from Borosilicate glass by Aijiren. Headspace vial can be available in 6ml – 20ml. Clear or Amber can be choose. Crimp Thread Headspace Vials use a 1.25 mm average wall thickness, which offers more reliability when internal pressures build. Our Headspace Vials meet or exceed OEM standards.

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 with 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 headspace 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 evaporate them at the top. 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.

Our Headspace Vial features a user-friendly design with a labeling area for easy sample identification and traceability. This enables efficient record-keeping and organization in your laboratory, ensuring accurate tracking and retrieval of crucial analytical information.

Headspace borosilicate glass vials are a type of glass containers designed for storing and analyzing gas samples. They are commonly used in analytical chemistry and the pharmaceutical industry. The term “headspace” refers to the area above the liquid or solid sample in the vial, which contains the gas phase of the sample.
Borosilicate glass is chosen for these vials because it has low thermal expansion properties, making it resistant to thermal stress and thermal shock. This is important because headspace vials are often subjected to heating and cooling during the sampling process.

Aijiren Tech headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability. All?Aijiren Tech headspace vials meet or exceed OEM instrument manufacturer¡¯s specifications.Aijiren Tech vials are available in 6ml, 10ml, 20ml versions with Screw and Crimp type.

The 18mm Screw Headspace Vial and Cap with electromagnetic screw seals used for CTC is novel in the headspace vial market dominated by crimping necks. Especially for magnetic caps that are difficult to crimp, screw caps are a convenient choice. 18mm Screw Headspace Vial and Cap with aluminum skirt and magnetic center plate, it is easy to crimp and remove the cap. 18mm Headspace Vial and Cap is preferred for the following instruments: CTC PAL, Varian, Gerstel, Atas, Shimadzu, Aijiren.

Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. 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 are made of Aijiren’s borosilicate glass. The 18 mm screw-neck headspace vials with magnetic screw seals for CTC are new in the headspace market where crimped necks dominate.

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.

This is referring to the screw-thread caps (18 mm) and crimp caps (20 mm) for 10 mL headspace vials.We don’t just recommend screw cap headspace vial or crimp cap headspace vial by “feel” or price, running a little experiment to compare the performance of the two kind of headspace vial caps.

Aijiren Headspace Vial and Cap facilitates automatic quality control or sample selection by performing headspace gas analysis. Common applications of Aijiren Headspace Vial and Cap include detection industry analysis, gas in polymers and plastics, volatile substances in beverages and foods, perfumes and cosmetics; also used to analyze the gasification of volatile organic solids and liquid samples. In recent years, the popularity of this technology has been recognized by laboratories around the world.

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.

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.

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.

Headspace vial is made of transparent or scarlet glass and is available on round or flat bases, crimp seals with bevel or square edge finishes, or thread finishes. Headspace viars, septaums, and caps can be purchased individually or collectively in different quantities as a convenient kit to meet the needs of the lab.
