A headspace vial is used in the process of top – gas chromatography. 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.

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.

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.

20mm Butyl Rubber Stopper
Material: butyl rubber
Usage: bottle mouth sealing

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 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.

The material of the headspace sample vials is low-extraction borosilicate glass, which is characterized by low expansion, high temperature resistance, high strength, high hardness, high light transmission and high chemical stability. Headspace vials are suitable for headspace analysis of volatile solids and gases. 20mm crimp headspace vial is widely used in Headspace and GC, GCMS application.

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.

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 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.

PTFE-fused septa are suitable to overcome the degradation, which happens due to prolonged high temperatures, commonly observed in silicone rubber septa. The degradation results in baseline drift and additional peaks. It is generally fixed with the PTFE face towards the column packing.

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 GC is a sample preparation method for determining volatile compounds in solid and liquid samples. Headspace sample vial is generally used for gas phase experiments.

Headspace vials are available in clear or amber glass, with round or flat bases, with beveled or square crimp seals, or with screw threads. Headspace vials, septum and caps can be purchased separately in various quantities or together as convenience kits to suit your laboratory needs.

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 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.

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.

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.
