NUCLEODUR® is a fully synthetical type B silica (silica of 3rd generation) offering highly advanced physical properties:
- Totally spherical particle shape
- Outstanding surface microstructure
- High pressure stability
- Low metal content
NUCLEODUR® as a state-of-the-art silica is the ideal base material for modern HPLC phases. It is the result of MACHEREY-NAGEL's pioneering research in chromatography for almost 50 years.
