Hummingbird Scientific SEM Stages for FEI and JEOL Scanning Electron Microscopes

Hummingbird Scientific’s SEM liquid cell system allows for real time imaging of solid-liquid interfaces in scanning electron microscopes. The system mount uses the same removable tip design as our liquid TEM holders, allowing for cross-correlative experiments across optical and electron microscope platforms. The two-chip fluid cell allows users to quickly and easily prepare and exchange samples while remaining confident in the cell’s seal.

Unlike environmental SEMs (ESEM) or SEMs with low-vacuum mode, Hummingbird’s SEM holder keeps your specimen at ambient pressure while the chamber is pumped down to high vacuum, ensuring high resolution imaging. Hummingbird’s SEM system also givers researchers precise control of fluid flow over the specimen surface and can be used for correlative studies between OM, SEM, and TEM.

Hummingbird Scientific has experience designing systems for numerous SEM manufacturers. Using a modular design approach, customizable holders and port interfaces, and a broad range of chips for electrochemistry and fluid flow experiments, we can customize a system specific to your experimental needs. We put safety first in all our systems by including a seal check station that minimizes the chance of leaks.
