Chromatography vials are containers used to transport your sample matrix to the instrument prior to injection. Aijiren offers a broad range of chromatography vials in a variety of volumes, material compositions, and closure types to meet the specific needs of a wide range of applications.

The associated 9 mm vial screw cap comes with your choice of septa constructed from either PTFE/silicone, PTFE/silicone/PTFE or PTFE/natural red rubber. Our screw vials and vial screw caps are designed for both HPLC and GC instrument platforms across a wide variety of applications, including pharmaceutical, environmental, energy and fuels

Silicone rubber septa. High quality, silicone rubber laminated to PTFE. Use when excellent resealing qualities are a must. Septum resists coring and is recommended when multiple injections are required. Preferred septa for use in liquid chromatography applications.

Most popular and economical septa for general GC purposes in Aijiren systems Pre-slit PTFE/red rubber – 8RT1X Pre-slit, high quality red rubber with a thin (0.003") layer PTFE. For applications using a very thin-gauge syringe needle or in instances when a vacuum may form in the vial. Silicone rubber.

General Purpose Septa for GC Aijiren’s general-purpose septa are made from an enhanced injection-molded silicone rubber material. The septa material, dark red or gray in color, is specified to withstand over 200 automatic injections at an injection port temperature of 350 °C.

Our precleaned, Type 1 borosilicate clear or amber glass vials are washed in non-phosphate detergent, rinsed three times with tap water, and rinsed with ASTM Type-1 organic-free water to remove detergent. Post cleaning, vials are assembled with PTFE/silicone septa and open-top polypropylene caps.

Available as both clear glass vials or amber glass vials , open top screw caps with PTFE/silicone septa, or PTFE lined storage screw caps that offer broad chemical resistance. Our storage screw top vial kits are used extensively in environmental, food, and pharmaceutical applications.

Excellent choice for general volatiles analysis. Septa are packed in a glass PurePak jar to assure low background, low permeability, and the highest performance of any headspace septum. PTFE/Silicone septa provide excellent resealing characteristics and broad chemical compatibility. Gray PTFE/Molded Black Butyl Septa (Pharmafi x Style): (C4020-36)
