Product Overview

Our 20mm crimp top headspace vials are the best for VOC analysis and Karl Fischer titration. They are the industry standard for secure sealing. The crimp finish makes a permanent, tamper-proof seal that stays strong even when exposed to intense heat.

High-Pressure Safety and Material Purity: These vials are made of strong glass that can handle the pressure inside when the sample is heated. The beveled neck lets the metal cap press down hard on the septa, making a perfect hermetic seal for sensitive analytes.

Key Features

Precision engineered for flawless sealing and instrument compatibility.

Pressure-Resistant: Thick glass walls handle pressures up to 10 Bar during incubation

Beveled Neck: Beveled 20mm crimp neck ensures a leak-proof, airtight seal.

USP Type I Glass: Minimizes alkali leaching and ghost peaks for trace analysis.

Universal Fit: Fully compatible with Agilent, Waters, and Shimadzu autosamplers.

Karl Fischer Ready: Specifically sized 6mL vials (22x38mm) for easy titrator integration.
