We are an official dealer of Macherey-Nagel products and we offer more than 900 HPLC columns of this high class manufacturer. Macherey-Nagel columns are available in numerous configurations. As an authorized dealer we offer you the entire product range by Macherey-Nagel.
HPLC columns are available in different configurations:
Nucleodur is a fully synthetical type B silica (silica of 3rd generation). We stock more than 600 types of Nucleodur columns by Macherey-Nagel. These columns offer highly advanced physical properties such as a totally spherical particle shape and an outstanding surface microstructure. With a high pressure stability and a low metal content Nucleodur is the ideal base material for modern HPLC phases.
Nucleosil phases are fully porous spherical silicas with a very pure and uniform SiO2 structure. Nucleosil standard silica phases are frequently used as routine packings for very different fields of chromatography and are a world-renowned HPLC packing. They were one of the first spherical silicas used in HPLC and are still found in many analytical and preparative applications. These phases are an absolutely reliable choice in HPLC and register the largest variety of modified HPLC silicas available on the market.
Macherey-Nagel Nucleoshell core-shell silica phases consist of a solid core of silicon dioxide and a homogeneous shell of porous silica. They offer the highest efficiency compared to traditional totally porous materials. Pore size 90 Å; particle size 2.7 µm (core 1.7 µm); specific surface 130 m2/g. Due to their lower back pressure Macherey-Nagel Nucleoshell core-shell silica phases can be used on conventional LC systems. Pressure stability up to 600 bar.
