ReproSil Star

Specialized Silica Phases for Pharmaceutical and Biotechnical Separations

The ReproSil Star series represents a range of special silica-based HPLC phases designed for demanding pharmaceutical and biotechnical separations. These phases are engineered to deliver exceptional selectivity, reproducibility, and robustness when analyzing complex biomolecules and pharmaceutical compounds.

ReproSil Star columns combine the mechanical stability of high-purity silica with precisely tuned surface modifications, ensuring sharp peak shapes and reliable performance even under challenging chromatographic conditions. They are ideal for method development, impurity profiling, and quality control in research and regulated environments.

ReproSil Star combines advanced silica technology with specialized surface chemistry – the reliable choice for high-performance separations in pharmaceutical and biotechnical analysis.
