UniHybrid Eterne Reversed Phase Bulk Media 10-120 C18, 5 kg (CAT#: STEM-C-3053-ZJF)

Silica reversed phase chromatography (RPC) is a widely used purification method for peptide-based therapeutics, including insulins and g-l-p-1 compounds. High pH conditions are often preferred in these processes, such as during column regeneration with 0.1M NaOH solution. However, conventional silica media typically have a short lifespan under these conditions. While hybrid silica particles are known for their high pH stability, they are generally limited to sizes below 10 µm and are primarily used in analytical HPLC applications. Currently, hybrid silica particles in sizes of 10 µm or larger are not commercially available for process-scale chromatography, likely due to their low surface area, high production costs, and the challenges associated with large-scale manufacturing. Hybrid-coated silica particles offer improved lifespans at high pH compared to conventional silica but still lack the stability of fully hybrid particles.
With advanced Precisely Controlled Silica (PCS) technology, monodispersed silica particles can be produced in large quantities at a low cost, achieving yields of nearly 100% per batch (several hundred kilograms). Leveraging this innovation, monodispersed hybrid silica particles—UniHybrid® Eterne—have been developed in a 10 µm size. These particles offer a high surface area, excellent mechanical strength, and more than ten times the chemical stability of traditional silica particles, addressing the demand for high-performance RPC media with exceptional pH tolerance.
