Headspace Vials And Closures
Headspace vials and closures are specialized containers designed for gas chromatography (GC) applications, particularly for volatile compound analysis. Made from clear or amber borosilicate glass, these vials offer high thermal resistance and come in flat or rounded bottom designs, typically with 20 mm crimp or screw necks.
Paired with precision-fit aluminum crimp caps and silicone/PTFE septa, they ensure airtight sealing and reliable sample integrity, making them ideal for analytical, pharmaceutical, and environmental labs.
Headspace Vials and Closures – FAQs:
Q1. What are Headspace Vials?
Headspace vials are specialized laboratory vials designed for gas chromatography (GC) headspace analysis, where the volatile compounds in the gas phase above a sample are analyzed. They are typically made from clear or amber borosilicate glass.
Q2. What are the types of Headspace Vials?
Common types include:
-
Crimp Top Headspace Vials – sealed with aluminum crimp caps and septa.
-
Screw Top Headspace Vials – easy to use with threaded closures.
-
Round Bottom and Flat Bottom Vials – depending on heating block compatibility.
Q3. What are Headspace Closures?
Headspace closures are caps and septa that provide a leak-proof seal for vials during analysis. They are usually made of aluminum caps with PTFE/silicone septa to withstand high temperatures and maintain sample integrity.
Q4. What are Headspace Vials used for?
Headspace vials are used in:
-
Gas Chromatography (GC)
-
Pharmaceutical testing
-
Forensic and environmental analysis
-
Food and beverage quality testing
-
Volatile organic compound (VOC) detection
Q5. What sizes are Headspace Vials available in?
Headspace vials are commonly available in:
-
6 mL
-
10 mL
-
20 mL (most widely used for GC headspace analysis)
Q6. What material are Headspace Vials made from?
They are typically made of Type I borosilicate glass for chemical resistance, thermal stability, and transparency. Amber glass options protect light-sensitive samples.
Q7. What factors to consider when choosing Headspace Vials and Closures?
-
Type of closure (crimp or screw)
-
Compatibility with autosampler and GC system
-
Septa material (PTFE/Silicone) for heat and chemical resistance
-
Glass type (clear or amber) depending on sample sensitivity
