Liquid System Static Cell

Liquid Static Flow

Hummingbird Scientific offers a sealed-cell liquid holder for static liquid applications. Once prepared, the sample is enclosed within a microfluidic liquid cell in the holder tip and separated from the vacuum of the TEM via a patented sealing mechanism. This tip can be paired with Hummingbird Scientific’s wide range of liquid-cell chip configurations, each aimed at a specific set of experimental requirements.

The continuous-flow and dual-flow configurations both also support static-liquid experiments for researchers interested in maximizing experimental flexibility.

(Above) A sequence of in-situ TEM images taken using Hummingbird Scientific’s liquid holder show the nucleation of CaCO3 on Au. Image at t = 0 shows initial gold electrode. By 38 seconds, CaCOnanoparticles have nucleated. By 120 seconds, the nuclei have coalesced and transformed into faceted CaCO3 with a typical calcite morphology.  Continued growth and coarsening ultimately result in a few dominant crystallites.
