Cap and Septas for 20mm Headspace Vial

A solid disk of PTFE offers superior chemical inertness against the most aggressive solvents. The thin membrane allows for easy penetration by most needles. PTFE septa are not resealable. They should be used with relatively short cycle times or single injection methods.

18mm screw top headspace borosilicate glass vial refers to a specific type of vial commonly used in gas chromatography (GC) analysis for the analysis of volatile compounds in samples.
It’s important to note that specific details of the vial, such as volume, thread type, and cap design, can vary between manufacturers and suppliers. Therefore, it’s recommended to consult the specific product specifications or contact the supplier for precise information about the 18mm screw top headspace borosilicate glass vials you are considering.

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

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.

Secure your most valuable samples with our High Quality Aluminum Crimp Caps, designed to provide reliable sealing solutions for a wide range of laboratory and industrial applications. Available in both 11mm and 20mm sizes

20mm Butyl Rubber Stopper
Material: butyl rubber
Usage: bottle mouth sealing

The 18mm Screw Headspace Vials are designed specifically for headspace analysis, a technique used to analyze volatile compounds in a sample. The vials accommodate the headspace sampling process, which involves collecting and analyzing the gas phase above a sample, providing accurate and representative results

The headspace sample bottles are available in 10 types of 10mL and 20mL volumes, with flat or round bottoms. The 20mm crimp cap provides an always guaranteed seal. Crimping or screw-top vials are available, with a beveled top for maximum safety sealing, two neck lengths are available, and flat-bottom or round-bottom designs are available.

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.

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;

The 20mm Crimp Cap is often used with Headspace Vial. It is tightly sealed and suitable for long-term storage of samples. The cap with center hole can be cut by septa, which is convenient for automatic sampling needle sampling.

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.

More convenient, consistent, and safer sealing process compared to crimping (better reproducibility). No risk of inaccurate or inconsistent crimping results. Due to thinner septa suitable for SPME as well as for Headspace. Often used on CTC Combi PAL and identically constructed autosamplers as well as on Perkin Elmer instruments.

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

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.

Headspace Crimpe Vials are available in volumes from 6 mL to 20 mL. We offer Headspace Crimpe Vials with a flat top or a beveled top, and are available with either a flat bottom or a rounded bottom Headspace Crimpe Vials for your application.

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.
