Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. A headspace vial is used in the process of top–gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial. The material of Headspace Vials is low extractable Borosilicate glass with a low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. Headspace Vials are suitable for headspace analysis of volatile solids and gases.

There are many differences between butyl and natural rubber. The main advantage is that butyl rubber has better chemical stability and aging resistance than natural rubber. It has the elasticity of natural rubber and does not contain protein ingredients, but it does not have butyl. Chemical inertness and aging resistance

Headspace vials are a kind of laboratory vials for top space analysis, with the features of high-temperature resistance and corrosion resistance. A headspace vial is used in the process of top–gas chromatography. When detecting volatile or semi-volatile mixtures with high boiling points, we need to heat them to vaporize them at the top. In this process, since the liquid samples are at the bottom, the material in the top gas can be measured without touching the liquid in the sample vial. The material of Headspace Vials is low extractable Borosilicate glass with a low expansion rate, high-temperature resistance, high strength, high hardness, high light transmittance, and high chemical stability. Headspace Vials are suitable for headspace analysis of volatile solids and gases.

The butyl rubber stopper is an off-white rubber-like solid with a density of 0.92g/cm3. It is odorless, insoluble in water, and soluble in hexane and chloroform. The product also has low air permeability, good airtightness, and good resistance. Ozone resistance, chemical resistance, electrical insulation, flexibility resistance, heat aging resistance, energy absorption and other characteristics.
