LiChrospher® WP 300 RP-18 LiChroCART®

Inner Diameter (I.D.): 4 mm
Length: 4 mm
Package Contents: 10 Pieces


LiChrospher® WP 300 RP-18 is a highly selective and reliable HPLC column for the separation of peptides and low 
molecular weight proteins. LiChrospher® WP 300 RP-18 enables the tailing-free separation of basic compounds and 
is excellently suited for the separation of tRNA molecules. High recovery rates are achieved, especially in the case of 
highly hydrophobic peptides.

With LiChroCART® cartridges the user works with re-usable endfittings which fit different cartridge lengths. 
Since these cartridge holders may remain in the system and the capillary connections do not need to be detached, 
the cartridges may be changed within the shortest possible time. Changing a separation cartridge from a length 
of 125 to 250 mm and back presents no problems. Furthermore, the adaptation of internal diameter (3 mm or 2 mm) 
to the analysis problem is possible within a few minutes. The endfittings are designed to allow the cartridges to be 
hand-sealed at normal working pressures of 150 to 200 bar without the need for any tools. Only at higher pressures 
may further tightening with a wrench become necessary.
