From the Waters Gradient Mixer kit, part number WAT051518:

Installing the gradient mixer

To install the gradient mixer: 

1. Position the gradient mixer on the bench top to allow easy visual leak detection. 
2. Connect the gradient mixer as shown in Figure 1:1 

“Gradient mixer 

connections”

. 

Note: 

If you are using 3 pumps, add another tee fitting (not included in the kit) 

as shown in the inset.

3. Be sure to use an in-line filter (part number WAT035190 included in the kit) 

since particles in the solvent can clog the 0.005-inch passages inside the 

gradient mixer.

Note:

 If you are operating a ternary pumping system, a second tee fitting (part 

number WAT075215) is required which is not supplied in the mixer kit.
