Product Intro

Engineered for High-Performance Chromatography

Our ND18 18mm precision screw thread headspace vials are the best way to store samples. These vials are made from USP Type I, Class A Borosilicate glass, which makes them very stable in both heat and chemicals. The high-purity glass reduces ion leaching and surface activity, which keeps delicate samples safe during high-temperature incubation cycles (up to 200°C).

Product Features

Superior sealing and pressure handling for reliable analytical results.

Precision Threading: Ensures a leak-proof seal and consistent headspace volume.

Rounded Bottom: Distributes internal pressure evenly during the heating process.

Robotic Compatibility: Perfect for CTC PAL and other robotic arm autosamplers.

Beveled Edge: Provides a robust rim that presses firmly into the septum.

High Grade Glass: 5.0 type borosilicate glass with excellent chemical resistance.
