Manufacturer and model: The Leica EM CPD300 is a fully-automated critical point dryer designed to preserve delicate specimen structures for high-resolution imaging. It accommodates both biological samples (e.g., pollen, tissues, insects) and industrial specimens (e.g., MEMS devices, micro-fluidic components) in a controlled drying process that prevents damage caused by surface-tension during liquid-to-gas transitions. Featuring intuitive software with a touchscreen interface and support for a wide variety of sample holders, the EM CPD300 ensures reproducible results with minimal user-interaction and optimized cycle times. Typical applications include: - Sample preparation for SEM imaging of biological specimens such as cells, tissues and small organisms. - Preparing industrial microstructures, MEMS, 3D micro-fabricated parts and micro-fluidic devices for microscopy. - Drying fragile, porous or high-aspect-ratio materials where conventional air or vacuum drying would cause structural collapse or deformation.
