1. A cell growth device comprising:
- a housing;
a motor;
a thermal control device;
a spectrophotometer;
a processor;
an electrical connection configured to be electrically coupled to the thermal control device; and
a rotating growth vial comprisinga vial;
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;
wherein the processor accepts input from a user, receives from the spectrophotometer the optical density of the cells in the vial, and through the electrical connection directs the thermal control device to adjust the temperature of the vial to grow the cells to a target value at a target time; and
wherein the processor is programmed to use wavelength values for blanks commensurate with growth medium in the vial.

Abstract
The present disclosure relates to methods and devices for automated control of cell growth rates where cell growth is measured in situ and the devices can be used as a stand-alone device or as a module in an automated environment, e.g., as one module in a multi-station or multi-module cell processing environment. The cell growth device comprises a temperature-controlled vial, a motor assembly to spin the vial, a spectrophotometer for measuring, e.g., OD of the cells in the vial, and a processor to accept input from a user and control the growth rate of the cells.
