China Wholesale 6ml-20mL GC Headspace Vials Manufacturer

Torticollis headspace sample vial, 10mL or 20mL volume, flat-bottomed or round-bottomed 20mm crimp top vial cap to ensure consistent safety sealing.

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.

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;

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.

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 20mm Caps with Septa are specifically designed for secure sealing and precise analysis of headspace samples in laboratory settings. These caps have a 20mm diameter, ensuring a tight and reliable fit on crimp headspace vials. The septa, made of high-quality materials, provide excellent sample integrity by preventing contamination and evaporation during storage and analysis.

Aijiren provides Screw Thread Headspace Vial always be applied to Aijiren, Shimadzu, Tekmar, CTC PAL, Varian, Gerstel, Atas, Thermo Scientific autosamplers. Aijiren’s Screw Thread Headspace Vial are all round bottom, this is because A rounded bottom is more sturdy and thus more resistant to the high pressure within the vial during the heating process.

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.

Aijiren’s Magnetic Precision Screw Metal Cap is 18mm in size, which is very suitable for sealing gas chromatography. This kind of cap is often used in headspace vials, and the center hole with it is very convenient for sampling by autosampler.

Headspace vials are a type of sample container used in analytical chemistry, specifically for headspace analysis. Headspace analysis involves the analysis of volatile compounds present in the gas phase above a sample. These volatile compounds are typically of interest in applications such as gas chromatography (GC) or gas chromatography-mass spectrometry (GC-MS).
Headspace vials are designed to hold the sample and create a sealed environment for the vapor phase above the sample. The vials are typically made of glass, although plastic vials are also available. The vials have a specific volume capacity, which can range from a few milliliters to several tens of milliliters, depending on the application.

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.

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
