Chromatogarphy instrument

GC headspace vial, also known as a gas chromatography headspace vial, is a type of sample vial used in headspace analysis. Headspace analysis is a technique employed in gas chromatography (GC) to analyze volatile or semi-volatile compounds present in a sample.
The headspace vial is specifically designed to hold the sample and create a sealed environment for the analysis. It consists of a glass vial with a crimp or screw cap closure. The vial typically has a rounded or conical bottom to facilitate the removal of air from the headspace.

Headspace borosilicate glass vials are specialized containers used in the pharmaceutical and scientific industries for the storage and analysis of gases or volatile substances. These vials are made from borosilicate glass, which is known for its exceptional thermal resistance and chemical inertness.
The term “headspace” refers to the space above the liquid or sample inside the vial, which contains the vapor or gas phase of the substance. In applications such as gas chromatography, where the analysis of volatile compounds is required, the headspace technique is commonly employed.

10ml 20ml laboratory bottles and vials are commonly used in scientific research and various laboratory applications.
Headspace vials are a specific type of laboratory vials designed for the analysis of volatile compounds in gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS).
It seems you are referring to two types of laboratory vials:
10ml and 20ml screw headspace vials made of either amber or clear glass, with aluminum caps.

The crimp caps of the vials is made of aluminum for crimping and sealing; plastic (polyethylene, polypropylene or phenolic resin) for non-crimping and sealing. The cap gasket is a septum material that is pierced by a syringe needle to extract a sample from the vial. The cap liner sheet has various configurations and is also made of various materials.

Chromatography autosampler vials are widely used in chromatography, chemistry, medical and other fields. Autosampler vials are generally made of hydrolytic glass or borosilicate, with various specifications. Different vial mouth designs meet different actual needs.

2 ml borosilicate glass vials are commonly used in high-performance liquid chromatography (HPLC) for sample storage and analysis.Borosilicate glass is preferred in HPLC because it offers excellent chemical resistance and thermal stability, making it suitable for handling a wide range of solvents and temperature conditions.When working with water samples in HPLC, borosilicate glass vials are a suitable choice due to their resistance to water and other polar solvents.

4 ml HPLC borosilicate glass vials are commonly used in high-performance liquid chromatography (HPLC) for sample storage and analysis. Borosilicate glass is preferred in HPLC because it offers excellent chemical resistance and thermal stability, making it suitable for handling a wide range of solvents and temperature conditions.

The headspace bottles are made of borosilicate glass and are produced by Aijiren. Pressed top headspace bottles are available in amber glass with rounded bottoms. Our headspace bottles meet OEM standards.

20mm crimp headspace vial is widely used in Headspace and GC, GCMS application. 20mm Aluminum Crimp Cap Seals and Vials ensure that a proper seal is made for this demanding application.

Headspace vial mainly used in gas chromatography analysis for headspace analysis. The Headspace Vial is used to extract the volatile components from the complex sample mixture, separate them from the non-volatile components and inject them into the gas chromatography system for separation

The headspace sample vial is used for the headspace analysis, especially for the volatile samples. The cap of the headspace sample vial must be properly and tightly pressed so that it will not affect the use of automatic instruments during the operation.

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.

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.

9 mm wide-mouth threaded PP HPLC vials: 9 mm screw caps, septa, and vials are designed for use with Aijiren and other rotary or robotic samplers. 12X32 mm vials are made of polypropylene with internal The micro-storage inner tank, this micro-groove can increase the storage level, and facilitate the sample to draw liquid from the automatic injection needle inside the Vias. These are the advantages of the micro vial compared to the ordinary automatic injection vial.

The 13-425 automatic sampling vial is produced by our company using high-quality imported raw materials from abroad. It is resistant to high temperature and corrosion; the cap is made of high-quality polypropylene, and the septum is made of the highest-quality material. Manufacturing tolerances and a controllable manufacturing environment ensure the high efficiency of product functions.

The 0.3ml micro amber pp vials produced by Aijiren has a V-shaped liquid storage groove, which can increase the liquid level and facilitate the extraction of the automatic injection needle. It is very suitable for rare or precious samples, and the PP material is extremely inert. It will affect the chemistry of the sample, and the color of Amber can avoid ultraviolet radiation to meet the needs of sample injection.

The Snap Cap is made of polypropylene, and the raised part of the Cap is very convenient to be stuck in the groove of Vias to ensure fixation. Septa is made of Silicone and PTFE adhesive-free composite. It is soft and easy to puncture. It is very suitable for automatic sampling. The side of PTFE in Septa faces the inside of Vias, sealing without affecting the sample.

The technical parameters of a 2ml transparent threaded sample bottle with a scale of 9-425 are as follows: Volume: 2mL. Shape: 12x 32 mm. Color: transparent or amber. Bottle scale: Yes (three levels: 0.5ml 1.0ml 1.5ml). Label writing: Yes. Bottle mouth thread: precision machined thread 8-425, always ensure sealing. Packing: 100/bag. Use with perforated cap: used as a sample bottle and washing bottle for chromatographic analysis autosampler.

ND11 Snap Neck Autosampler Vials is suitable for most autosamplers on the market. It has a wide neck design and is easy to fill. It is suitable for 6mm diameter intubation tubes. Sample bottles with inscriptions provide graduated labels for easy sample identification. High-quality imports generally use 5.0 The glass tube is made of borosilicate hydrochloric acid, and the lid is made of polyethylene material to reduce the damage caused by repeated use of the lid

Aijiren provides a 0.3ml Snap Neck micro bottle in order to meet the all-round needs of customers. Once Micro Vials was launched, it has received wide acclaim. For experiments that require less sampling and samples are more precious, the Micro Vial produced by Aijiren is very suitable for this type of experiment.
