The time it takes for half of a bacterial population to become phage adsorbed is easy to calculate as approximately the reciprocal of the product of phage titer and the phage adsorption rate constant.

Mixing minutes with hours, milliliters with liters, or absolute numbers with concentrations simply will not do! (Regardless, I'm assuming that volumes are in millimeters and time is in minutes.)
