18mm screw Top Headspace Borosilicate Glass 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.

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.

The Lab Use 20mm Crimp Headspace Vial is specifically designed for accurate and reliable analysis of headspace samples in laboratory settings. With its 20mm crimp neck, these vials ensure a secure and leak-proof seal during sample collection and analysis, maintaining sample integrity and preventing contamination.

Headspace vials are laboratory vials used for headspace analysis and are characterized by high temperature and corrosion resistance.

Headspace vials are used in headspace gas chromatography processes. They are suitable for headspace analysis of volatile solids and gases.

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.

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.

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.

18mm Magnetic Metal Cap with Center Hole for more convenient for the automatic injection needle to perform sample injection.Generally speaking, the Septa in the 18mm Closures uses a double-sided compound of Silicone and PTFE Septa, which makes it difficult for Septa to react with reagents, and it can also protect impurities in the air from falling into the vial.

Headspace vials are common consumables generally used in gas phase experiments.  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 is a supplier of laboratory consumables, focusing on the production of 10mL 18mm Screw Thread Headspace Vial for GC. Aijiren has more than ten years of experience in making 10mL 18mm Screw Thread Headspace Vial and is a well-known brand among Chinese laboratory consumable suppliers. Aijiren strives to provide quality service to every customer.

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.

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.

20mm crimp-top headspace borosilicate glass vial is a specific type of vial used in headspace analysis, a technique commonly employed in gas chromatography (GC). These vials are designed to store and analyze samples for volatile compounds.
Headspace analysis involves the sampling and analysis of the vapor phase above a sample, typically done to analyze volatile compounds that can be released from solid or liquid samples.
The headspace vials are specifically designed to withstand the increased pressure and temperature conditions associated with this technique.It’s important to note that Headspace vials may also be available with other closure mechanisms, such as screw caps or magnetic caps.

The butyl rubber product is an off-white rubber-like solid with a density of 0.92g/cm3. It is odorless, insoluble in water, and soluble in hexane and chloroform. The product also has low air permeability, good airtightness, and good resistance. Ozone resistance, chemical resistance, electrical insulation, flexibility resistance, heat aging resistance, energy absorption and other characteristics.

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.
