NUCLEODUR® high purity silica phases for HPLC

Features

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.
