VHP precolumn filter - how to replace

Instructions for installation of replacement filters and proper use of the assembly

  1. Insert the Replacement Filter Unit into the bottom half of the VHP Precolumn Filter Assembly, as shown. (NOTE: The 0.2 μm Replacement Filter Unit has a groove at the top, whereas the 0.5 μm Replacement Filter Unit does not have a groove. Both are pictured to the left.)
  2. Ensure the replacement filter unit is fully installed and the tubing extends completely past the end of the ferrule tip
  3. Tighten the complete assembly into the inlet port of the column, hand-tightening first and then applying 10 inch-pounds (1.10 N-m) of tightening torque -- roughly equivalent to 1/3-1/2 turn past hand-tight.
