20mm crimp-top headspace Borosilicate Glass vials for Gas for Lab Gas chromatography analysis
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.
1.The crimp-top prevents sample contamination and minimizes the loss of volatile compounds during storage and analysis.
2.20mm size of the crimp-top vial is a standard size used in many headspace analysis systems.
3.Borosilicate glass, which is commonly used in these vials, has excellent resistance to thermal shock.
4.Borosilicate glass is chemically inert and resistant to most common laboratory solvents and reagents.
