(5) Preparation Chamber with Cryo Shield Assembly |
| Features | Benefits |
|---|---|
| Custom-designed preparation chamber | Allows integration of the various cold fracture modules |
| Turbo molecular vacuum pumping | High capacity pumping: ideal for biological/high surface area samples |
| LN2 cooled cryo-shield assembly | Active trapping of water and other evolved gases produced during fracturing |
 |
|
Modules (1)-(4) are mounted on a sample chamber which features a turbo molecular pump and an inner cryo shield assembly (shown in blue below). The cryo shield assembly is LN2 cooled and has various openings into which the cold fracture modules are inserted. By maintaining the cryo shield at liquid nitrogen temperature, researchers have observed a significant reduction in the magnitude of the pressure bursts during fracturing of biological material. This results in cleaner, fractured surfaces. |
