Our specimen holders extend the capabilities of the Transmission Electron Microscope. Conduct your experiments in-situ in the TEM.
Our sample stages extend the capabilities of the Scanning Electron Microscope / Focused Ion Beam Microscope. Conduct experiments inside the SEM or prepare your specimen inside the FIB.
To get the most out of your TEM holders use Hummingbird Scientific's selected TEM holder accessories.
Researchers at UC Davis and Pacific Northwest National Laboratory utilized a continuous flow in-situ liquid stage developed by Hummingbird Scientific to capture direct images of individual proteins and macromolecular complexes in a fully hydrated environment without freezing or chemical fixation. They were able to capture images of both static (b, white arrow) and moving (b, white arrowhead) ferritin proteins with a spatial resolution better than 2nm.
