Calculate the amount of cell suspension and medium you need for your cell harvest.
Vc = Volume of cell suspension [mL]
r = growth rate [1/d] t = growth time [h]
ρ 0 = cel suspension density [cells/mL]
ρ t = planned harvest density [cells/cm2]
Vd = device volume [mL]
Nt = total harvest [cells/device]
