A critical point dryer is an advanced device designed for moisture removal, utilizing the unique state achieved at the critical point of a substance, where its surface tension drops to zero. This method heats steam or gas to a precise temperature and pressure where these conditions are met.
The principle of operation hinges on reaching this critical point, enabling the seamless transition of substances from liquid to gas without the intermediate phase, effectively eliminating moisture. This technique is particularly beneficial for preserving the structural integrity of sensitive samples.
This technology is instrumental across various scientific and industrial applications, including the drying of microorganisms, biological tissues, pharmaceuticals, and industrial products. A typical critical point dryer comprises a heater, a sample chamber, and an exhaust system. The heater, often powered by a steam boiler or gas burner, raises the substance to its critical point. The metal sample chamber secures the specimen during the process, while the exhaust system, equipped with filters or dryers, safely removes the transitioned gases. This method stands out for its rapid drying capability, unaffected by the sample's size or shape.
