General description

HPLC cartridge
Superspher® RP-18 endcapped is a reliable and versatile traditionally produced spherical silica gel carriers with C-18 encapped reversed revered 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 250-4 HPLC cartridge. The connection to the HPLC system is being accomplished by use of the manu-CART NT cartrige holder (1.51486).
