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 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.

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.

Our 18 mm 10 mL screw-top bottles are made from premium borosilicate glass to withstand the rigors of GC and headspace analysis, ensuring the long-term integrity and stability of your precious samples

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.

1. Septa and slit septa are available. 2. The usually available cap color is silver, and other special colors can also be produced accordingly. 3. Easy to apply and easy to remove. 4. Aluminum sealing ring with pre-inserted septum is compatible with standard opening crimp top vials.

20ml precision screw headspace vial, 18mm, round bottom, top space vial, strong adsorption. Headspace vials are manufactured to provide uniform glass thickness which insures even heat distribution for consistent sampling reliability.

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.

Headspace vials are typically larger than the 2 mL volumetric flasks used in many liquid sampling systems. Headspace vials are commonly available in 10 mL and 20 mL capacities.

Headspace vials are common consumables generally used in gas phase experiments. Headspace samples are usually prepared in vials containing sample, dilution solvent, matrix modifier and headspace.

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.

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 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 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

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.

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.

ND20 Crimp-top headspace refers to a specific type of headspace vial closure system used in gas chromatography (GC) for the analysis of volatile compounds.
ND20 headspace analysis can be performed using different techniques, such as static headspace, dynamic headspace, and purge and trap.
Each technique has its own advantages and is suitable for specific sample types and analyte properties.
