Liquid System Heating

IR image of MEMS heating chip in Hummingbird Scientific Liquid Flow Holder
Our liquid heating system is specifically optimized for moderate temperature requirements. Each chip features its own thin-film heater, which heats the contents of the liquid cell up to the boiling point of your solution.

The system’s custom heating-control box and software user interface features closed-loop temperature control and integrated protection against boiling.  Hummingbird’s heating chips are specially calibrated for this system in order to ensure optimal capability.  The image shows an example of the heated liquid cell membrane under a thermal camera.

Visualizing compartementalization in adaptive microgels

Researchers at RWTH Aachen University, DWI − Leibniz-Institute for Interactive Materials and theHelmholtz-Zentrum Berlin für Materialien und Energie have used Hummingbird Scientific’s liquid-heating TEM platform to visualize  compartementalization in adaptive microgels.  They recently presented their findings in Nano-letters.

Compartmentalization in soft materials is important for segregating and coordinating chemical reactions as well as  sequestering (re)active components. The authors show the direct visualization of different compartments within adaptive microgels using a combination of in-situ electron and fluorescence microscopy.  By acquiring an unprecedented levels of structural details they address the challenge of reconstructing 3D information from 2D projections for nonuniform soft matter as opposed to monodisperse proteins. They also show the thermally induced shrinkage of responsive core–shell microgels in water. Applying the methods used in this work more broadly open doors for in-situ studies of soft matter systems and their application as smart materials.
