HPLC Column NUCLEODUR® PolarTec is an HPLC column with a particle size of 1,8 µm and column dimensions of 30 × 4 mm, supplied as 1 pc(s) for liquid chromatography. This NUCLEODUR® PolarTec format is positioned for chromatography work, including environmental analysis and broader liquid chromatography applications in the laboratory. The short 30 mm bed length combined with a 4 mm internal diameter gives a compact hardware footprint for HPLC systems that specify PolarTec chemistry at 1,8 µm. Unit weight is 0,119 kg, supporting straightforward handling during installation or column exchange. The product is offered from manufacturer MACHEREY-NAGEL as a single-piece pack, matching the stated unit quantity for one-column use rather than multi-packs. Laboratories running liquid chromatography methods can place this column where NUCLEODUR® PolarTec, 1,8 µm, 30 × 4 mm is required by the method or instrument configuration. It fits category use across applications, environmental analysis, chromatography, and liquid chromatography without altering the defined particle size or geometry. The combination of PolarTec designation, micrometre-scale packing, and the 30 × 4 mm format provides a clear specification set for purchasing and system setup in analytical HPLC environments.
