    316 Stainless Steel


    316 Stainless Steel is one of the most popular manufacturing materials currently being used in chromatography applications. It offers tremendous physical strength as well as the best chemical resistance of all of the 300-series stainless steels. Because of the metallic nature of this material, it is best to compare the chemical being used with a database listing to determine if any interaction is suspected.

    Delrin®



    Delrin® is a rugged polymer that serves as an excellent choice for long-term mechanical stability for products such as fittings and threaded adapters. It is important to note that Delrin, while being strong mechanically, cannot tolerate to be in the presence of acidic or basic solutions for long periods of time, as the polymer will degrade. It is best to use Delrin with neutral pH aqueous solutions or organic solutions for guaranteed best performance.

    Perlast®


    Perlast® Perfluoroelastomer is a special type of rubber material designed to offer the unique chemical resistance of PTFE. It shares with PTFE a polymer backbone consisting of carbon atoms protected by fluorine atoms, making it very inert to chemical attack. As a rubber, therefore, it is resilient, so it doesn’t creep or flow but retains sealing force over a long period. Perlast can be used in long-term conditions and has a very low oxygen permeability. It also stretches – aiding installation.

    High Purity PFA


    High Purity PFA differs from PFA simply in the amount of impurities left behind in the polymer matrix. Already one of the cleanest polymers on the market, PFA still had too many impurities for such industries as the medical and semiconductor industries. For these types of specialized needs, a higher purity form of PFA was developed. Differing only in the level of impurities, High Purity PFA offers all the same benefits of regular PFA.

    PK (Polyketone)


    PK: A proprietary polymer blend comprised mainly of polyetheretherketone (PEEK). PK demonstrates all of the superior chemical resistance of PEEK (see PEEK above). The proprietary blend will however, allow a fitting to attain a higher pressures while reducing the cold flow properties of pure PEEK. CAUTION: some fittings molded of PK are known to be conductive. Use caution when employing PK fittings in high voltage applications.

    Polypropylene


    Polypropylene is used across many industries as a good, general-use polymer. It offers resistance to many standard chemical solutions across the full pH range, making it a product of choice for many applications. There are chemicals that will interact with polypropylene, either degrading it, discoloring it, or causing it to crack, and as such, it is important to ensure that the chemical solutions being used are compatible with this polymer. Such chemicals include chlorinated and aromatic solutions, as well as some organic solvents.

    PPS (Polyphenylene Sulfide)


    PPS (polyphenylene sulfide) is a highly chemical resistant polymer for room temperature and slightly elevated temperature applications. Great care should be taken, however, when using the polymer in elevated temperatures, as studies have shown the polymer to lose much of its chemical resistance properties when the temperature is too high. Additionally, the chemicals that show an effect with PPS are not pH dependent; however it is recommended to investigate specific compatibility prior to using strong acids or bases and some halogenated organic solutions.

    Tefzel® ETFE (Ethylene TetrafluoroEthylene) Extended Properties


    Tefzel® is a molecular relative of PTFE, and as such, is highly chemically resistant. It has proven to be an excellent material for sealing surfaces and for applications where aggressive solvents are being used and durable tubing is necessary for the application. Tefzel is also used for threaded products, particularly in our low pressure line of products and adapters. Please note that caution must be taken when using some chlorinated solvents with Tefzel, as they may interact and degrade or swell the polymer slightly.

    Titanium


    Titanium products were created initially as a biocompatible alternative to stainless steel — something that did not have ferrous components. While being a metal and therefore offering a higher temperature rating than polymers can offer, titanium does not exhibit the same strong chemical resistance that stainless steel does, and is particularly susceptible to attack by strong acidic or basic solutions. There are many other solvents that will interact with titanium, so it is recommended that a chemical compatibility chart be consulted.

    TPX® (polymethylpentene)


    TPX® (polymethylpentene) is used sparingly in the Upchurch Scientific product line. It offers good chemical compatibility across the full pH range. However, it is suspect to attack by halogenated chemicals and a number of organic solutions as well. Additionally, research has shown that, as the operating temperature reaches and exceeds 60 °C, the resistance to chemical attack is lowered considerably.

    UHMWPE (Ultra High Molecular Weight Polyethylene)


    UHMWPE (ultra high molecular weight polyethylene) is a commonly-used polymer which offers resistance to many chemical solutions, particularly aqueous-based ones. The polymer is durable and ideal for use in many “room temperature” applications. Care should be taken when using anything that is manufactured from UHMWPE in conjunction with some organic solutions as well as chlorinated solvents and nitric acid.

    Vespel®



    Vespel® is a frequently-used polyimide material, often found in use with valves. While often adequate for use in systems where the chemicals do not go out of the pH range of 1 to 10, Vespel is susceptible to alkaline attack. This means that ammonia, hydrazines, amines, and any solution that surpasses pH 10 should be avoided. Also, strong oxidizing agents should be avoided or at least used with caution.
