Crimp Vials And Closures
Crimp vials and closures are precision glass containers used for sample storage and analytical applications like HPLC and GC. Made from high-purity borosilicate glass, these vials are designed with crimp neck finishes to ensure a tight, tamper-proof seal when used with aluminum crimp caps and PTFE/silicone septa.
Available in clear and amber glass, with capacities typically ranging from 1.5 mL to 20 mL, they offer excellent chemical compatibility and sample integrity—ideal for pharmaceutical, environmental, and research laboratories.
Crimp Vials and Closures – FAQs:
Q1. What are Crimp Vials?
Crimp vials are small laboratory vials sealed with an aluminum crimp cap and septum, widely used in chromatography (HPLC, GC, LC-MS) for secure sample storage and analysis. They ensure airtight sealing, preventing sample evaporation and contamination.
Q2. What are the different types of Crimp Vials?
-
Standard 2 mL Crimp Top Vials – most common for HPLC/GC.
-
Wide Opening Crimp Vials – easier for sample filling.
-
Amber Glass Crimp Vials – protect light-sensitive samples.
-
Clear Glass Crimp Vials – for general chromatography use.
Q3. What are Crimp Closures?
Crimp closures (caps) are aluminum seals with PTFE/silicone septa designed to tightly seal crimp vials. They provide leak-proof performance and are compatible with autosamplers used in chromatography.
Q4. What are Crimp Vials and Closures used for?
They are primarily used in:
-
Gas Chromatography (GC)
-
High-Performance Liquid Chromatography (HPLC)
-
Pharmaceutical testing
-
Environmental and forensic analysis
-
Food and beverage quality control
Q5. What sizes are Crimp Vials available in?
Crimp vials are available in different volumes, commonly:
-
1.5 mL – 2 mL (most widely used in autosamplers)
-
10 mL, 20 mL (used in headspace and larger volume testing)
Q6. What are Crimp Vials made of?
They are usually made of Type I borosilicate glass for chemical resistance and thermal stability. Amber vials are used for samples sensitive to light.
Q7. What are the advantages of Crimp Vials over Screw Vials?
-
Provide tighter, more secure seals.
-
Better for volatile and sensitive samples.
-
Reduced risk of evaporation compared to screw caps.
-
Widely accepted in regulated pharmaceutical and analytical labs.
