Catalog number: TS-13019. For a convenient, versatile, and cost-effective vial and closure system, choose Aijiren Tech™ Screw Cap Septum Vials. Made of autoclavable borosilicate glass and available with a wide assortment of special closures and accessories, these vials are ideal for sample collection and small derivatization reactions
The septum is provided with a thin 0.005” PTFE layer laminated to highly pure silicone, and slit through the center for easier needle penetration and to release the vacuum that forms when a large volume of sample is withdrawn from a vial.
A variety of vials, closures, and vial accessories in a range of sizes, shapes, and material compositions designed for various scientific applications; includes autosampler vials and accessories, dilution vials, scintillation vials, and serum vials. Autosampler vials come in convenient pre-packaged sets. Other options include general-purpose
Analytical Vials. Vials play a significant role in analytical analysis and result reproducibility. Vials must be inert and free of extractables or leachables to prevent affecting results. Using certified, application-specific, contaminant-free vials can significantly reduce risk. We offer a broad spectrum of Supelco ® products including
Both recommended options provide 2 lines of defense against sample loss: 1) mininert valves have a PTFE valve backed up by a cylindrical red rubber septum and 2) certain vials have a capillary tube opening backed up by a PTFE-lined cap. Handling procedures can have a large impact on standard integrity.
Glass Vials with 0.060″ Septa feature protective packaging, and a thinner septum that is optimized for automation. Hard foam divider holds vials securely separated, each in their own individual cell for ultimate vial protection. Hard foam sectional design allows clusters of nine (9) vials to

Siliconization involves applying a silicone solution to the surface of the glass to create a protective layer. The benefits of silicone vials include: Minimal interaction between the sample and the vial. Prevents high-viscosity fluids from sticking to the internal surface of the vial. Increases transparency.
