ReproSil 70 C18

Small-Pore C18 Column for Fast, High-Efficiency Separations

ReproSil 70 C18 from Dr. Maisch HPLC GmbH is a fully porous, high-purity silica HPLC column with a 70 Å pore size and an octadecyl bonded phase. The small pore size provides a high surface area, resulting in strong hydrophobic retention and high separation efficiency for small molecules, such as pharmaceuticals, pesticides, and environmental contaminants. This column delivers sharp peak shapes, high resolution, and excellent reproducibility, making it ideal for routine analytical applications where speed and efficiency are critical.

ReproSil 70 C18 columns from Dr. Maisch HPLC GmbH combine small-pore efficiency with strong hydrophobic selectivity – the preferred choice for small-molecule HPLC separations.
