10ml 20ml Crimp-top glass headspace GC Borosilicate Glass vials with 20mm aluminum Cap and Septa
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.
1.It reduces the risk of sample contamination and can withstand high temperatures, making it suitable for a variety of analytical applications.
2.The borosilicate glass material ensures that the vials can withstand long-term storage without degradation or leaching.
3.Aluminum caps are generally sturdy and resistant to damage, making them suitable for handling and transportation of samples.
4.Aluminum caps are compatible with various vial types, including crimp-top vials, and can provide a secure seal when properly crimped.
