I am just wondering what might have caused this as this is happening many number of times and also in 12 wells and 6 wells plates. I know it might be because of edge effect/evaporation but the medium volume looks very much the same in all wells but i could see a change in color on the side wells. Incubator we use is a new one and everything seems to be fine. How to rectify these problems or else any other alternatives. greatly appreciate your answers.
thanks,
