Hi
 
I have been using a Peloris for about 4 years now with excellent results.  The point to understand is that the instrument will always use the cleanest/purist of each reagent type last so when 2 runs are going at the same time they will be competing for the same last alcohol, xylene etc.  You will run into problems if for example you try to start a 1 hour run two hours after a 4 hour run as it may be delayed due to a clash in choice of reagent.  If possible always start a shorter run before a longer run.
 
I have not had a problem with water carryover but I have noticed that when exclusively using the reagent pump in/pump out facility that there is a small amount of reagent which can not be removed by the pump which will over time reduce the purity of reagents, so it is worthwhile to occasionally remove the containers and tip out any residue before refilling.
 
regards
