Passage numbers explained - Culture Collections
2017. 2. 17.· Passage number does not consider the seeding densities used or cell numbers subsequently harvested and so typically gives little indication of the actual number of population doublings. For example, one cell culturist may split a cell culture noted to be at passage number 10 by 1:4 and another cell culturist could split the same culture at a ratioSeparating Minerals by Floatation,2021. 2. 15.· A typical copper operation contains many floatation cells, often with a pH sensor in each cell. The number of sensors and their locations vary from plant to plant, being largely dependent on solution chemistry.
