The HettCube 600 R is an innovative incubator which has a low environmental impact while being able to achieve a cooling capacity which enables the optimum growth conditions for cell cultures. It only heats or cools when necessary and only consumes 0.049 kWh at an operating temperature of +37°C, making it cost-efficient and energy-efficient. Housed on the outside of the usable space is the fan, which reduces the air flow. The cells housed in the incubator are protected against desiccation as the incubator is heated through radiated heat. The incubator is quiet during use due to the novel ventilation system.
