Built to deliver predictable results in synthesis routines, the HPLC Column Nucleodur ® SIOH, 250 mm, 21 mm offers exceptional performance for normal phase applications. Featuring an unmodified phase made from high purity NUCLEODUR ® silica gel, this preparative separation column is ideal for separating polar and midpolar compounds. With a particle size of 5 µm and a pore size of 110 Å, it provides a specific surface area of 340 m²/g, ensuring efficient separation. Its temperature stability up to 60°C and pressure resistance at 400 bar make it suitable for various experimental conditions. The column's surface chemistry, consisting of unmodified high purity silica gel (SIOH), facilitates polar and ionic interactions, further enhancing its versatility.
