ASI™ 20mL Glass Crimp Top Headspace Vials, 20mm Beveled Finish, 100/Pk

Designed for everyday chromatography analysis, ASI™ 20 mL Glass Crimp Top Headspace Vials offer an affordable, high-quality solution compatible with all headspace GC instruments. Manufactured from clear Type I borosilicate glass, these vials provide exceptional thermal and chemical resistance, making them ideal for volatile gas analysis.

Key Features:

• Superior Glass Quality – Made from 1st hydrolytic class borosilicate glass (Type I) for enhanced chemical resistance and durability.
• Beveled Finish – Reduces the sealing surface between the crimp seal and the glass for a more secure and consistent closure.
• Standard 20 mm Crimp Top – Ensures compatibility with a wide range of crimp seals and autosamplers.
• Optimal Size for Headspace Analysis – 22.5 × 75 mm dimensions allow precise sample containment.
• Flat Bottom Design – Preferred for manual headspace autosamplers and applications requiring a slight downward vial inclination.
• Thicker Glass Walls – Designed to withstand higher temperatures and internal pressures, ensuring reliable performance in headspace GC applications.
• Specification Certified – Dimensionally verified and inspected to meet US, EU, and JPN Pharmacopoeia requirements, ensuring autosampler compatibility.
• Lot Traceable – Every batch is 100% traceable through the manufacturing process for quality assurance.

Applications:

• Quality Assurance & Quality Control (QA/QC) Testing
• Environmental Analysis (VOC detection)
• Pharmaceutical and Food Safety Testing
• Industrial and Petrochemical Analysis

These vials can be securely sealed using 20 mm aluminum crimp caps and septa (sold separately) with a manual or electronic crimper tool for airtight sample integrity.

Ensure reliable, precise, and reproducible results in your chromatography workflows with ASI™ 20 mL Crimp Top Headspace Vials.
