Tube Heating System for Drying a Liquid Cell

Tube Heating System for Drying a Liquid Cell

Princeton Docket # 25-4187

 

This innovative tube heating system developed by researchers at Princeton University represents a significant advancement in liquid phase transmission electron microscopy (TEM) technology. Previous systems have struggled with prolonged downtime, which limits productivity and the ability to conduct in situ experiments. However, this new design efficiently heats gas flow from 68 to 130 °F, effectively drying liquid cells assembled on liquid phase TEM holders in just 2 hours, which is far superior to the 48 hours required when using room temperature gas flow. The system comprises three essential components: a gas flow controller, an induction heater, and a temperature controller. This integrated design allows for precise control over the heating process, enhancing the efficiency and reliability of the system.

The potential advantages for this technology are vast, particularly for makers and users of liquid phase TEM systems. Laboratories investing heavily in advanced liquid phase TEM technology will find that this novel system significantly reduces downtime, allowing for more experiments and better utilization of valuable equipment. By incorporating this tube heating system, researchers will not only enhance the efficiency of their workflows but also improve the quality of TEM imaging, enabling more accurate examinations of reaction products in a dry environment.
