Applied Biosystems 0711-0203 Spheri-5 HPLC Column

Applied Biosystems 0711-0203 Spheri-5 HPLC Column is a 5 µm SPHERI-5 packing designed for analytical high-performance liquid chromatography, utilizing a silica-based stationary phase to deliver consistent retention and peak shapes across typical separations. The column measures 220 mm in length with a 2.1 mm internal diameter, offering efficient separations in a compact form factor that fits standard liquid chromatography systems supporting narrow-bore columns. As part of the Spheri-5 family, this variant is intended for routine HPLC workflows where reproducibility and stable performance are required, and it accommodates a variety of mobile phases and gradient conditions used in common method development. The model number 0711-0203 is sometimes cataloged with the PTH designation, reflecting its specific lineup within SPHERI-5, and together these specifications describe a column optimized for speed and efficiency in small- to moderate-scale separations.
