SEM specimen drying equipment

SEM specimen drying equipment. Critical-point dryer and freeze-dryer for scanning electron microscope (SEM) specimen preparation. Scanning electron microscopes use electrons to view objects at magnifications much higher than can be obtained using light waves. The preparation of the object being scanned often includes stages such as drying the sample. Freezing can be done to obtain freeze-fractured samples to reveal details of internal structures.

EDITORS COMMENTS
This print showcases the state-of-the-art SEM specimen drying equipment, a critical component in preparing samples for scanning electron microscopy. Located at a renowned university laboratory in Plymouth, UK, this cutting-edge technology plays a pivotal role in advancing scientific research. Scanning electron microscopes revolutionize our ability to observe objects with unparalleled magnification by utilizing electrons instead of light waves. However, before these objects can be scanned, meticulous preparation is required. This includes the crucial step of drying the sample to ensure optimal imaging quality. The photograph captures two remarkable machines: the freeze-dryer and critical-point dryer. The freeze-dryer enables scientists to obtain freeze-fractured samples that unveil intricate details of internal structures through controlled freezing and subsequent sublimation of ice crystals. On the other hand, the critical-point dryer facilitates gentle drying by replacing liquid solvents with carbon dioxide gas under carefully calibrated conditions. With its sleek design and advanced functionality, this equipment represents technological progress in 21st-century science. Its presence underscores the dedication of researchers at this prestigious institution who strive to unlock new insights into various fields ranging from biology to materials science. This awe-inspiring image from Science Photo Library serves as a testament to human ingenuity and highlights how innovative tools like these propel us towards greater discoveries on our quest for knowledge and understanding.
