Avantor-ACE® UltraCore™ are (U)HPLC columns from Avantor based on core-shell (Fused-Core™) technology. The silica-based stationary phases consist of a non-porous core and an porous outer layer, that provides fast separations without excessive backpressure. Avantor-ACE® UltraCore™ columns are available with different modifications.
