Restek Corporation products

Hub-Cap 4-Liter Bottle Tops

Hub-Cap bottle tops are a great way to neatly keep your mobile phase lines where they belong. Use them instead of plastic paraffin film, aluminum foil, or tape on your mobile phase reservoirs.

Vacuum Gauges

High-quality vacuum gauges with 316 stainless steel wetted surfaces.–30"Hg to 0"Hg. Recommended for use with passive sampling kits. All are rear mount.

Trident - LC Column Protection System

Unlike “one size fits all” guard systems, the Trident LC column protection system gives you the power to select just the right level of protection for your work. With three levels of protection and a variety of guard cartridges and cap frits, you can select the best combination to match your specific analytical needs. Choose a filter alone to remove particulate matter, a guard cartridge alone to remove irreversibly adsorbed compounds, or both a filter and a guard cartridge for maximum protection. The economical, leak-free design provides a highly versatile combination of convenience, economy, and reliability.

HPLC and UHPLC Columns

Pinnacle - Biphenyl Columns (USP L11)

Pinnacle DB columns are 100% manufactured by Restek in our Bellefonte, Pennsylvania facility. Because performance begins with the support, our Pinnacle DB UHPLC columns start with base-deactivated spherical silica that is optimized for UHPLC stability. From there, we bond them with a wide variety of phases to give chromatographers a stable and selective column. Get the most out of your UHPLC system. Combine selectivity and efficiency by using Restek Pinnacle DB UHPLC columns. Since 2005, the Restek Biphenyl has offered a greater degree of dispersion than conventional phenyls and a greater degree of polarizability than phenyl hexyls, creating higher selectivity and a greater range of usability. Because of these heightened interactions, this column shows substantial increases in retention—especially for dipolar, unsaturated, or conjugated solutes—and enhanced orthogonal selectivity when using methanol mobile phases.

Pinnacle - DB IBD UHPLC Columns (USP L68)

Pinnacle DB columns are 100% manufactured by Restek in our Bellefonte, Pennsylvania facility. Because performance begins with the support, our Pinnacle DB UHPLC columns start with base-deactivated spherical silica that is optimized for UHPLC stability. From there, we bond them with a wide variety of phases to give chromatographers a stable and selective column. Get the most out of your UHPLC system. Combine selectivity and efficiency by using Restek Pinnacle DB UHPLC columns. The Restek IBD is a polar-embedded column that acts as a strong hydrogen bonder and may be the most versatile column available today. With a unique polar group, this column is very retentive and selective for acids. It also provides symmetrical peak shape for strong bases. Restek’s IBD is compatible with 100% aqueous mobile phases and can be used under reversed-phase or HILIC conditions to retain very polar, ionic compounds in highly organic mobile phases.

Pinnacle - DB PAH UHPLC Columns

Pinnacle DB columns are 100% manufactured by Restek in our Bellefonte, Pennsylvania facility. Because performance begins with the support, our Pinnacle DB UHPLC columns start with base-deactivated spherical silica that is optimized for UHPLC stability. From there, we bond them with a wide variety of phases to give chromatographers a stable and selective column. Get the most out of your UHPLC system. Combine selectivity and efficiency by using Restek Pinnacle DB UHPLC columns. Specifically designed to resolve complex mixtures of polycyclic aromatic hydrocarbons (PAHs). Get complete resolution of all 16 EPA 610 PAHs, plus two other routinely analyzed PAH compounds, in less than five minutes to greatly reduce run times and increase sample throughput.
