HPLC (High-Performance Liquid Chromatography) and GC (Gas Chromatography) vials are essential components in analytical chemistry, used for sample storage, handling, and injection. Here’s a detailed overview of the different types of vials you might offer:
HPLC Vials
1
Standard Vials
- Material: Typically made from clear or amber glass to protect samples from light.
- Volume: Common volumes are 1.5 mL, 2 mL, and 4 mL.
- Neck: Available with crimp or screw caps.
- Applications: Used for general liquid chromatography applications.
2
Insert Vials:
- Feature: Typically made from clear or amber glass to protect samples from light.
- Material: Common volumes are 1.5 mL, 2 mL, and 4 mL.
- Volume: Typically smaller, such as 0.3 mL or 0.5 mL.
3
Auto-Sampler Vials
- Feature: Designed for use with auto-samplers in HPLC systems.
- Caps: Available with pre-slit septa to facilitate automatic injection.
- Material: High-quality glass or plastic with a focus on consistency and low adsorption.
GC Vials
1
Standard Vials
- Material: Clear or amber glass, with a focus on chemical resistance and low reactivity.
- Volume: Usually available in sizes like 1.5 mL, 2 mL, and 4 mL.
- Neck: Available with screw or crimp top closures
2
Headspace Vials:
- Feature: Designed for use in headspace analysis where the vial’s headspace is analyzed instead of the liquid sample.
- Material: Typically larger, such as 10 mL or 20 mL, to accommodate the headspace required.
3
Screw Thread Vials:
- Feature: Equipped with screw caps for easy sealing and resealing.
- Material: High-quality glass with a focus on ensuring a tight seal to prevent sample evaporation.
Common Features for Both HPLC and GC Vials
- Sealing Options: Caps are available with septa made from various materials like PTFE (Polytetrafluoroethylene) or silicone to ensure a proper seal and prevent contamination.
- Quality Control: Vials are typically manufactured under strict quality controls to ensure consistency and minimize contamination.
Offering a range of HPLC and GC vials with these features can help cater to diverse needs in the analytical and research communities.
