Here is a Beckman Coulter JE-5.0 Elutriation System

This is a complete and fully functional system that was removed from the J-26XP. Below manual shows how it should be installed.

Rotor does not include elutriation cells. Buyer needs to acquire particular ones needed.

It might also work on J-26XPI but we would need to confirm with Beckman.

Beckman Coulter JE-5.0 Elutriation System

Manufacturer Description and Specification:

Centrifugal elutriation in the Beckman Coulter JE-5.0 Elutriation System combines two separation technologies: centrifugation, the process of sedimentation under the influence of a centrifugal force field, and counterflow elutriation, the process of separation by washing. 

In the Beckman Coulter JE-5.0 Elutriation System, separation takes place in a funnel-shaped elutriation chamber. Each cell in the chamber is acted upon by two opposing forces: centrifugal force (driving it away from the axis of rotation), and fluid velocity (driving it toward the axis of rotation—“counterflow”). While the rotor is spinning in the centrifuge, a suspension of cells is pumped at a preset flow rate from outside the centrifuge into the rotor to the narrow end of the elutriation chamber. As suspended cells are introduced into the chamber, they migrate according to their sedimentation rates to positions in the gradient where the effects of the two forces upon them are balanced. Small cells with low sedimentation rates are quickly washed toward the axis of rotation, where they are caught in an increasing flow velocity caused by the rapidly narrowing chamber walls. These cells are washed out of the chamber, up through the rotor, and out into a collection vessel. Somewhat larger or denser cells move through the chamber more slowly and reach equilibrium at the elutriation boundary, where the centrifugal force and the velocity are relatively low and the chamber walls are at their widest point. The largest or densest cells remain near the inlet to the chamber where centrifugal force and fluid velocity are high. By increasing the flow rate in gradual steps, successive fractions of increasingly large or dense cells can be washed out of the rotor and collected. Continued incremental increase of the flow rate will finally elutriate all cells from the chamber.

During the run, you can view the processes taking place in the chamber by looking through the port in the centrifuge door. The clear resin elutriation chamber is illuminated from below by a strobe light that is synchronized with the speed of the rotor.
