Wholesale 20mm Crimp Top Aluminum Caps with Septa Supplier

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.

Crimp caps squeeze the membrane between the edge of the glass bottle and the crimped aluminum cap. This creates a good seal and prevents evaporation. Crimp cap vials require a hand crimper tool to perform the sealing process.

There are many differences between butyl and natural rubber. Butyl rubber is a synthetic elastomer known for its excellent sealing properties, chemical resistance, and flexibility. 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.

The Hand Decrimper is typically designed to work with two common crimp cap sizes, which are 11mm and 20mm. These sizes correspond to the diameter of the crimp caps, indicating their compatibility with specific vial sizes. This tool is typically made of durable materials such as stainless steel or high-quality aluminum. These materials are chosen for their strength and resistance to corrosion, ensuring long-lasting performance. The decrimping features a handle, often designed with ergonomic considerations for comfortable and efficient use by laboratory personnel. The handle provides a firm grip for precise control during the decrimping process.

The 20mm 20ml Crimp Top Headspace vial has a 20mm outer diameter, which is the standard size for crimp-style headspace vials. The 20ml capacity refers to the volume of the vial, meaning it can hold up to 20 milliliters of liquid or gas sample. These vials are typically made from high-quality borosilicate glass. Borosilicate glass is chosen because it is resistant to chemical reactions and can withstand high temperatures, making it ideal for containing volatile samples without contamination. 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.
