1. A method for using a cell growth device, comprising:
- transferring an aliquot of cells into cell growth device comprising;
a housing;
a motor;
a thermal control device;
an electrical connection configured to be electrically coupled to a thermal control device;
a spectrophotomer;
a processor;
and a rotating growth vial comprisinga vial comprising growth medium;
a drive engagement mechanism configured to engage with the motor to spin the vial; and
a light path through the vial for a light beam generated by the spectrophotometer, wherein the spectrophotometer is configured to measure and deliver to the processor an optical density of cells in the vial;
entering a user-preferred target optical density and a user-preferred time to reach the user-preferred target optical density into the processor wherein the processor accepts input from a user, receives from the spectrophotometer the measure of the optical density of the cells in the vial, and through the electrical connection directs the thermal control device to adjust a temperature of the vial to grow the cells to the user-preferred target optical density at the user-preferred target time; and
wherein the processor is programmed to use wavelength values for blanks commensurate with the growth medium in the vial.
