SEM LiquidHow it Works

Hummingbird SEM Liquid ElectroChemistry Stage in Microscope

Hummingbird Scientific’s SEM liquid system encloses the sample within a microfabricated liquid cell in the holder tip, which is sealed from the microscope chamber environment by a patented sealing mechanism. The fluid pump and power supply are located safely outside of the chamber. A customizable chamber interface and vacuum sealed supply system provide fluid and power to the tip. Using Hummingbird’s two-chip fluid cell, users can prepare their sample of choice using the same methods they would for any other electron transparent membrane substrate. The tip can be swapped between light microscopes, the SEM, and the TEM for cross-correlative studies.

The holder’s liquid-cell assembly and safety features protect your SEM’s vacuum system from contamination and damage during experimentation. Interchangeable tips and replaceable tubing allow researchers to perform controlled and cross-contamination-free experiments and to easily upgrade the system to incorporate new capabilities. Each system comes with an SEM-specific seal-checking station, which checks the entire system from port flange to tip before inserting the cell into the microscope’s vacuum chamber.
