A portable, thermally insulated container having an isothermal chamber for storing temperature sensitive material. An electronic circuit activates a heater when the temperature in the chamber is below a preselected magnitude and activates a Peltier heat pump to cool the chamber when the temperature in the chamber is above a preselected magnitude. The electronic circuit operates a fan for the intake of air into the chamber while the Peltier heat pump is operating and discontinues the operation of the fan while the heater is operating. Included in the elec...
A container for temperature sensitive material comprising: (a) a chamber for storing temperature sensitive material; (b) a temperature sensor responsive to the temperature in said chamber; (c) a cooling device for cooling said chamber; (d) a first operational amplifier, which operates as a waveform shaper for controlling the operation of said cooling device; and (e) a second operational amplifier responsive to said temperature sensor to control the operation of said first operational amplifier for controlling the temperature in said chamber.
