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
Septa Vial septa are available in a variety of materials. Septa are selected based on the chemical properties of the sample and the temperature to which the vial will be subjected during the analysis. Several septa are available with either slits or a starburst pattern pre-cut into them. These cuts provide a
For applications involving automated transport of vials, magnetic caps are recommended. The cap liner or septa is the part of the cap which establishes a tight seal with the vial. Liners and septa can be laminated with PTFE on one or both sides, which results in high chemical resistance and a nearly inert barrier between sample and septa material.

Septa for use with general chromatography vials, liquid injection 2-056 PTFE/Natural Red Rubber PTFE Natural Red Rubber are moderately priced seals for GC and HPLC with good chemical properties. They are ideal for multiple injections due to high resealability, but not as easy to penetrate as PTFE/RR.
Choosing the right septa for your work. In the same way that chemical composition underpins the choice of a vial, chemistry is an important factor in choosing the right septa for your work. The best analytical performance will be achieved with a septum in the cap of your vial that protects your sample and is as chemically inert as possible.
An analytical chemistry method is described for measuring the reactivity and permeation of fabrics, films, and other solid materials. Headspace GC or GC/MS instrumentation is used. A vial in a vial method is used, in which the volatile agent is placed in a small inner vial, and the inner vial is capped with a layer of fabric or film to be tested.
