Superspher® RP-18 endcapped is a reliable and versatile traditionally produced spherical silica gel carrier with C-18 endcapped reversed phase properties. They are well suited for the separation of neutral, acidic and weak basic compounds. This high performance silica carrier with a particle size of 4µm yields an excellent pressure/separation performance ratio. This sorbent is packed into a LiChroCART® 25-4 HPLC cartridge. The connection to the HPLC system is being accomplished by use of the manu-CART® 25mm cartridge holder (1.50017).
