Brava is a high-efficiency HPLC column series based on fully porous, high-purity silica and advanced bonding technology. Designed for analytical applications that require strong retention, high resolution, and excellent peak symmetry, Brava columns are available with reversed-phase and normal-phase chemistries such as C18. They are ideal for demanding pharmaceutical, chemical, and environmental analyses where robustness and reproducibility are essential.
Brava columns offer performance, stability, and selectivity for laboratories requiring dependable results in demanding reversed-phase HPLC applications.
The product line was aquired by Dr. Maisch HPLC GmbH in 2016 from Grace / Alltech.
