CombiFlash® Rf User Manual
The CombiFlash Rf 150 system has drain tubes extending
from its top shelf and back panel. The tubes drain away any
liquid spilled on the top shelf and the tray beneath the fraction
collection racks.
1. Test the fraction collector drain by connecting a vacuum or
air supply source to the outlet end of the drain tube. Then,
verify the presence of such vacuum or air supply source on
the drain (Figure 3-4).

2. Test the top shelf drain by connecting a vacuum or air
supply source to the outlet end of the drain tube. Then,
verify the presence of such vacuum or air supply source on
the drain (Figure 3-5).
3. Route the end of both drain tubes to a suitable waste fluid
collection container.
Note
It may be necessary to extend the drain tube. If so, splice the
tubing with user-supplied tubing. The user-supplied tubing should
have an inside diameter no smaller than the existing drain tubing,
and must be compatible with the solvents used by the system.
Route this extension tubing to the waste collection vessel.
