Restek Pinnacle DB™ & Pinnacle II™ HPLC Columns – Proven Performance for Reliable HPLC Method Development

The Restek Pinnacle DB™ and Pinnacle II™ HPLC column series combines high-performance stationary phases with premium silica technology to deliver reliable, reproducible separations for routine analysis, method development, and quality control. Designed for pharmaceutical, environmental, food, forensic, and chemical laboratories, these fully porous silica columns provide excellent efficiency, robust peak shapes, and consistent chromatographic performance.

Pinnacle DB™ columns are manufactured using high-purity, base-deactivated spherical silica optimized for both HPLC and UHPLC applications. The silica support features a 140 Å pore size and 150 m²/g surface area, providing excellent stability and reproducibility across a wide range of analytes. Available particle sizes include 1.9 µm, 3 µm, and 5 µm, allowing seamless method transfer between UHPLC and conventional HPLC systems.

The Pinnacle II™ HPLC series is built on high-purity spherical silica with 3, 4 and 5 µm particle size and 110 Å pore size with 180 m²/g surface area, offering excellent mechanical stability, high efficiency, and outstanding batch-to-batch consistency for conventional HPLC. Available in popular reversed-phase selectivities such as C18 and C8, Pinnacle II columns provide reliable retention, excellent peak symmetry, and long column lifetime, making them ideal for routine analytical methods and validated laboratory procedures.
