从China供应商批发进口20ml Headspace Autosampler Vials — FOB条款

This 20ml headspace autosampler vial is specifically designed for gas chromatography and headspace analysis applications requiring precise sample containment and thermal stability. The vial is constructed from quality glass suitable for volatile compound analysis, featuring dimensions compatible with major autosampler brands including CTC, Gerstel, and Teledyne systems. The 20ml capacity provides adequate sample volume for headspace sampling techniques while minimizing solvent consumption. The vial design incorporates a flat bottom base ensuring stable positioning in autosampler trays and consistent thermal transfer during heating cycles. The product is engineered for use with standard magnetic screw caps and septa commonly used in headspace chromatography.

The vials are available in different glass compositions to accommodate various chemical properties and analytical requirements. Typical borosilicate glass construction provides excellent chemical resistance and thermal shock resistance required for headspace oven heating. The vials feature optimized wall thickness to withstand repeated heating cycles without cracking or deformation. Closure options include magnetic screw caps with PTFE/silicone septa providing reliable sealing during analytical procedures. The flat bottom design ensures proper seating in autosampler sample trays and consistent injection positioning. Surface treatment options may be available to reduce adsorption of analytes onto glass surfaces for sensitive applications.

These headspace vials are essential consumables for research laboratories, pharmaceutical quality control, environmental testing facilities, and food safety analysis laboratories. Primary buyers include analytical instrument distributors, laboratory supply companies, and research institutions requiring consistent vial performance for volatile compound analysis. The product supports applications in volatile organic compound analysis, residual solvent testing in pharmaceuticals, environmental pollutant monitoring, and food flavor compound profiling.
