Sample Vials and Caps: The Foundation of Precision Analysis

Sample vials are the essential, high-precision containers used across chemical, basic, and life science laboratories for the reliable storage, preparation, and introduction of samples into analytical instruments. They form the critical first link in the analytical chain, where sample integrity is paramount.

J&K provides a comprehensive range of high-quality sample vials engineered for performance and compatibility. Our vials are designed to seamlessly integrate with major autosampler systems, including Agilent/HP, Shimadzu, PerkinElmer, and others, supporting automated workflows in research, quality control, and diagnostic laboratories worldwide.

Product Features for Vials:

• Material Excellence: Manufactured from premium USP Type I borosilicate glass, ensuring exceptional chemical inertness, clarity, and resistance to thermal shock.

• Precision Design: Uniform wall thickness and flat-bottom construction guarantee consistent heating, reliable seating in autosampler trays, and optimal performance.

• Secure Sealing: Featuring beveled necks and standardized threads/crimp finishes (e.g., 9mm, 12mm, 18mm, 20mm) for a perfect, leak-proof seal with the appropriate cap and septum, protecting sample integrity.

• Robust & Sterilizable: Capable of withstanding autoclaving for sterilization and suitable for use across a wide temperature range.

Applications:

• Liquid Chromatography (HPLC, UHPLC) and Gas Chromatography (GC, GC-MS) sample analysis

• Storage of standards, reagents, and sensitive analytical samples

• General sample handling and preparation in pharmaceutical QA/QC

• Environmental testing and clinical diagnostics

• Academic and industrial research & development
