Screw Headspace Vial

1) Description

Screw Headspace Vial is a specially designed laboratory vial mainly used for headspace sampling in chromatographic analysis. These vials have a precision thread design that fits tightly with the corresponding threaded cap, ensuring that the sample does not leak during analysis. Headspace vials are commonly used in gas chromatography (GC) and liquid chromatography (HPLC) analyses, especially when volatile compounds need to be separated from liquid or solid samples for analysis. These vials are usually made of glass or specific plastic materials to withstand the various chemical and physical conditions that may be encountered during chromatography.

2) Application

Screw Headspace Vials are mainly used in gas chromatography (GC) and liquid chromatography (HPLC) analysis, especially in headspace sampling technology. This technique is used to extract volatile compounds from liquid or solid samples. Common applications include:

• Environmental Analysis: Detecting contaminants in water and soil samples.
• Food and Spice Analysis: Identification of aroma components in foods or spices.
• Pharmaceutical Industry: Quality Control of Pharmaceutical Ingredients.
• Chemical Analysis: Analyzing the composition and purity of chemicals.

These Vials are suitable for use in environments requiring high precision and sensitivity, and can adapt to different temperature and chemical conditions.

3)Features

▶ Pre-assembling vial+closure service is available upon request.
▶ The magnetic screw caps can be used for headspace as well as for SPME.
▶ Type of Cap: Magnetic Precision screw cap, Closed Precision screw cap.

▶ The professional precision screw design makes the septa and vial more airtight. When used as a headspace sample vial, the operation is more convenient and safe, and it can ensure good repeatability of analysis results.
▶ Screw technology makes it easier to open and tighten, and samples can be removed on site instead of in the laboratory.
