Application

  • Gas Chromatography (GC): Used to store and transport samples of gases or volatile organic compounds. In GC analysis, the sample needs to volatilize at high temperature, so there are high requirements for the sealing of the vial.
  • Liquid Chromatography (LC): In particular, High Performance Liquid Chromatography (HPLC) analysis is used to store liquid samples. The 9-425 vial is designed for use with autosamplers, allowing for accurate and rapid injection of samples into the column.
  • Sample Preservation: This vial is also commonly used to preserve chemicals, biological samples, or other sensitive materials for long periods of time, especially samples that need to be preserved under specific conditions.
