Pharmalox® is a high purity alumina ceramic (>99.7% Al2O3) specially designed for our products.
The high purity of this material results in very clean grain boundaries which contribute to its excellent corrosion resistance in the presence of both acid and alkali-based cleaning solutions e.g. NaOH and HCl.
Pharmalox® is inert, non-cytotoxic and does not release particles. It is easy to clean due to the low porosity. It has high wear resistance, a low friction coefficient and accepts very smooth surface finishes.
