HPLC replacement guard cartridge C18, 3.0*4

The analytical column configured with our exclusive end fitting. The external cap frit in the end fitting can be replaced by removing the end fitting, pulling off the old frit, and pushing a new frit into place. When replacing the end fitting, tighten less than 1/8 turn past finger-tight—there is no need to overtighten this connection.
For maximum protection against particulate matter and sample contaminants, the system can be configured with both an integral guard cartridge and a replaceable external frit. To assemble this configuration, remove the end fitting, insert the appropriate 1 cm or 2 cm guard cartridge into the Trident end fitting, attach anfitting to the Trident end fitting, and connect the end fitting to the fitting. Do not overtighten any of these connections.
