ReproShell
Core-Shell HPLC Columns for High-Efficiency and Fast Analytical Separations
ReproShell is a high-performance HPLC column series from Dr. Maisch HPLC GmbH, packed with core-shell (superficially porous) silica particles for ultra-fast, high-resolution separations. The innovative particle design combines a solid core with a porous outer shell, reducing diffusion paths and leading to sharper peaks, lower backpressure, and greater efficiency — even at standard HPLC pressures.
Available with various bonded phases such as C18, C8, and phenyl-hexyl, ReproShell columns are ideal for laboratories seeking maximum performance in routine, regulated, or high-throughput environments.
ReproShell columns from Dr. Maisch HPLC GmbH deliver top-tier core-shell performance – ideal for fast, precise, and efficient analytical HPLC.
