How it works

The SEM Liquid Flow Sample Holder uses an enclosed microfluidic liquid cell to maintain a controlled liquid environment inside the high vacuum of the SEM. The liquid cell is formed by two silicon microchips with electron-transparent silicon nitride (SiN) windows that encapsulate a thin liquid layer while allowing the electron beam to image dynamic processes in liquid environments.

‍

A precision-engineered, screw-free chip loading and compression-sealing mechanism ensures reproducible liquid cell assembly and self-alignment of the imaging windows for consistent experimental performance. The holder is compatible with specialized microfabricated chips for MEMS heating, electrical biasing, and liquid electrochemistry, enabling multiple in-situ techniques on the same liquid-flow platform.

‍

Liquid is delivered to the holder tip through replaceable flexible microfluidic tubing. The standard configuration supports both static and continuous liquid flow, while an optional dual-inlet configuration enables two independent solutions to mix immediately before the imaging region. Continuous flow refreshes the liquid environment throughout the experiment, enabling reagent exchange, removal of reaction by-products, and real-time observation of dynamic liquid-phase processes.
