After incubation, I notice that the outside of the CELLine is wet. Why is this?
If medium is placed in a flask that is not pre-warmed, there will be considerable condensation accumulation on the outside of the CELLine. Due to the large volume of medium contained in the CELLine, this condensation can be significant. The condensate takes time to evaporate in the humidified incubator. To verify that the liquid is not from a leak, verify that the liquid is colorless by blotting with white paper. IF there is no coloration, the liquid is water and due to condensate.
