Allsphere columns are based on high-purity, fully porous silica and offer dependable performance for routine reversed-phase HPLC applications. Designed with a balanced surface chemistry and available with common bonded phases such as C18, Allsphere columns deliver reliable retention, good peak shape, and reproducible results at an excellent price-performance ratio.
This column family is especially well suited for laboratories performing standard reversed-phase separations in pharmaceutical, environmental, food, and chemical quality control. Whether used for method development or validated workflows, Allsphere provides a practical and robust solution.
Allsphere is a reliable choice for laboratories seeking solid reversed-phase performance in day-to-day chromatographic routines.
The product line was aquired by Dr. Maisch HPLC GmbH in 2016 from Grace / Alltech.
