Headspace vial is made of transparent or scarlet glass and is available on round or flat bases, crimp seals with bevel or square edge finishes, or thread finishes. Headspace viars, septaums, and caps can be purchased individually or collectively in different quantities as a convenient kit to meet the needs of the lab.
20ml precision thread headspace vial, 75×22.5mm, clear glass, borosilicate glass, round bottom 18mm combination seal: magnetic univerisal screw cap, silver, centre hole, ptfe/silicone or ptfe/butyl septa
Headspace vials are typically larger than the 2 mL volumetric flasks used in many liquid sampling systems. Headspace vials are commonly available in 10 mL and 20 mL capacities.
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
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.
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.
Suitable for: 18mm screw top headspace vials Cap material: magnetic metal Cap features: 8mm center hole Color: Metallic Silver Septa material: PTFE / silicone Septa size: 17.5*1.5mm Package: 100pcs/pack
Material: USP1, Borosilicate Glass 10ml Precision Screw Neck 18mm Diameter Color: Clear / Amber Bottom: Round Bottom Vial Size: 22.5*46mm Cap: 18mm Magnetic Precision Screw Metal Cap Septa: PTFE/Silicone 17.5*1.3-1.5mm PTFE/Transparent Silicone Septa 1.3mm for SPME
Gas in the vial enters the gas phase detection. Top-space gas analysis using headspace viars can help automate quality control or sample selection. Use state-of-the-box equipment to prepare your entire experiment for accurate analysis through repeatable samples.
Headspace vials are available in clear or amber glass with a round or flat base, a crimp seal with a beveled or square edge finish, or a screw-thread finish. Headspace vials, septum, and caps can be purchased in various quantities separately or together as convenience kits to fit your laboratory needs.
Aijiren Tech crimps 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 is also optional.
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.
Material: USP1, Borosilicate Glass 20ml Precision Screw Neck 18mm Diameter Color: Clear / Amber Bottom: Round Bottom Vial Size: 22.5*75mm Cap: 18mm Magnetic Precision Screw Metal Cap Septa: PTFE/Silicone 17.5*1.3-1.5mm PTFE/Transparent Silicone Septa 1.3mm for SPME
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. Aijiren supply ND18 screw headspace vial in wholesale price, welcome to inquiry. You can also find Aijiren by those channel.
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 samples are typically prepared in vials containing sample, dilution solvent, matrix modifier, and headspace. Volatile components of a complex sample mixture can be extracted from the non-volatile sample components and separated in the headspace or gas portion of the sample vial.
The metal cover provides the widest temperature tolerance range and is very resistant to impact cracking. The metal cover is very suitable for gas chromatography applications. The metal cover is made of steel (chrome-plated or tinplate anti-corrosion coating) or aluminum.
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.
Our Headspace Vial features a user-friendly design with a labeling area for easy sample identification and traceability. This enables efficient record-keeping and organization in your laboratory, ensuring accurate tracking and retrieval of crucial analytical information.
18mm septa use only the highest quality materials to ensure proper function, specifically for GC applications, ensuring the septum does not fall into the vial during sample injection.
