NUCLEODUR® high purity silica phases for HPLC

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
Download the Nucleodur Catalog, or  an overview of available NUCLEODUR® phases.
 
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.
NUCLEODUR® is  also available with 1.8 µm particle size for increased separation efficiency
