Ultrasep ES Pharm RP18

Pharmaceutical-Grade C18 HPLC Column

Ultrasep ES Pharm RP18 is a silica-based HPLC column with a pharmaceutical-grade C18 bonded phase. Designed for pharmaceutical and biotechnological applications, it offers strong hydrophobic retention, excellent reproducibility, and robust performance under routine and demanding analytical conditions.

Compared to shorter-chain C8 phases, Pharm RP18 provides higher hydrophobic selectivity, making it particularly suitable for drugs, metabolites, and other hydrophobic compounds. Its stable bonding chemistry ensures consistent results and long column lifetime, even under method development and regulatory testing.

Ultrasep ES Pharm RP18 delivers reproducible, pharmaceutical-grade C18 performance – the trusted choice for versatile and robust HPLC separations in drug development and quality control.

Key Features:

  • Silica-based stationary phase with pharmaceutical-grade C18 bonding

  • Strong hydrophobic retention for a wide range of compounds
