Headspace vials are a type of laboratory vials used for gas chromatography. They are designed to contain samples that will be analyzed using headspace gas chromatography, a technique used to analyze volatile compounds in solid or liquid samples. The vials are sealed with a septum cap, allowing the headspace above the sample to be analyzed without exposing the sample to the atmosphere. This technique is commonly used in pharmaceutical, environmental, and food analysis, among other fields.
Headspace vials, also known as gas chromatography (GC) vials or sample vials, are specialized containers used for the analysis of volatile compounds in gas chromatography. They are designed to store samples and create a headspace above the sample, which contains the volatile components to be analyzed.

EPA vial, also known as an Environmental Protection Agency vial, is a type of sample vial specifically designed for environmental analysis, particularly in the context of water and soil testing. The EPA has established certain standards and regulations for environmental testing, and EPA vials are designed to meet these requirements.
EPA vials are typically made of inert materials, such as borosilicate glass, to minimize interactions between the sample and the vial. They are available in different sizes, typically ranging from 20 mL to 40 mL, to accommodate various sample volumes.

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 GC (Gas Chromatography) vials are specialized sample vials used in headspace analysis. Headspace analysis is a technique used in analytical chemistry to analyze volatile compounds in a sample.
In headspace analysis, a sample is placed in a sealed vial, and the volatile compounds in the sample equilibrate with the headspace (the space above the sample) inside the vial. The vial is then heated to a specific temperature, causing the volatile compounds to vaporize and distribute themselves in the headspace.

Screw glass vial refers to a type of container made of glass that has a screw-on cap or closure mechanism. These vials are commonly used for storing and transporting various substances, such as liquids, powders, or small solid samples, in scientific, pharmaceutical, and industrial applications.
The screw-on cap ensures a secure and airtight seal, preventing the contents of the vial from leaking or being contaminated. This feature is particularly important when storing sensitive or valuable substances that require protection from moisture, air, or other external factors.

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.

Screw vials are a type of laboratory vials used for storing and transporting liquid or solid samples. They are designed with a screw cap closure system, which provides a secure seal and prevents sample leakage. Screw vials are commonly used in various scientific fields, including chemistry, pharmaceuticals, environmental analysis, and more.
On the other hand, EPA vials are a specific type of vials that comply with the requirements set by the United States Environmental Protection Agency (EPA). These vials are used for environmental analysis and are typically used for the collection and storage of water samples, soil samples, and other environmental samples.

10/20 mL screw neck headspace vial is a type of laboratory container commonly used in analytical chemistry and pharmaceutical applications.
It is specifically designed for the analysis of volatile compounds in a sample using a technique called headspace analysis.
The vial features a screw neck, which means it has a threaded opening that allows for a secure closure using a cap or septum.
The screw neck design ensures a tight seal, preventing any leakage of the sample or the escape of volatile compounds during analysis.

A 20ml EPA Amber screw vial is a type of laboratory container commonly used for the storage and transport of samples in environmental analysis。
The 20ml EPA Amber screw vial is commonly used in environmental analysis for the storage and transportation of water, soil, or air samples.
It is suitable for various analytical techniques, including gas chromatography (GC), liquid chromatography (LC), and mass spectrometry (MS).

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.

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.

10ml 20ml Headspace GC vials are a type of sample vial used in gas chromatography (GC) analysis.
They are specifically designed for the analysis of volatile and semi-volatile compounds present in a sample.
Headspace analysis involves the extraction of volatile compounds from a solid or liquid sample into the gas phase for injection into a GC instrument.
20mm aluminum caps and septa are commonly used in chromatography applications, including gas chromatography (GC) and high-performance liquid chromatography (HPLC). They are used to seal sample vials and ensure a gas-tight or liquid-tight seal.
