Last Drop Mobile Phase Filter

Last Drop Mobile Phase Filter
  • The Last Drop mobile phase filter utilizes a flat filter element which sits parallel to the bottom of the reservoir.
  • This design allows the filter to draw all but the last 2% of the mobile phase from the reservoir without drawing air into the system. Conventional cylindrical mobile phase filters begin to draw air into the system when as much as 10% of the solvent remains in the reservoir.
  • The body is constructed of PTFE, with either a 1/4"-28 female fitting (PEEK nut and ETFE ferrule supplied) or a tripod (stepped) tubing connector which accommodates 1.5, 2.2, and 3.5 mm ID tubing. We recommend the metal-free PTFE version for sensitive biochromatography applications where metal surfaces may corrode and contaminate the solvent with ions.
