Amerigo Scientific offers UniHybrid® Eterne monodisperse hybrid silica particles in 10 µm size for the purification of peptides and proteins such as insulins, GLP-1, and their mimics. Based on the innovative Precisely Controlled Silica (PCS) technology, large quantities of UniHybrid®Eterne monodisperse hybrid silica particle can be produced at low cost. UniHybrid®Eterne particles have a high surface area, good mechanical strength, and chemical stability more than 10 times that of conventional silica particles, which can meet the high requirements of RP-HPLC media with high performance and pH tolerance.
