Devices, systems and methods for controlling environmental conditions of substances

An apparatus, comprising:

• an environmental control element configured to control at least one environmental condition of a substance;
• a substance chamber configured to contain the substance, wherein:
• the environmental control element includes a thermal insulator configured to provide a thermal shield for the substance, and a phase change material (PCM) configured to thermally regulate the at least one environmental condition;
• the substance chamber includes a wall surrounding the substance chamber;
• and
• the environmental control element is configured to control the at least one environmental condition without use of an external power source,
• a thermally conductive element configured for establishing a uniform temperature distribution over at least one of a volume of the PCM and between the wall and the PCM, and
• a control capacity indicator and a sensor the control capacity indicator configured to display a remaining environmental condition control capability provided by the PCM,
• wherein;
• the thermally conductive element is positioned in any one of:
• the volume of the PCM and between the wall and the PCM, and
• the remaining environmental condition control capability is calculated based upon changes in the PCM sensed by the sensor.
