-- How does Stirling Cryocooler 77K work in freeze-fracture devices, and freeze-driers for cryo-electron microscopy – Lab professors all use 60 to 80 Liter of liquid nitrogen per day.
The Stirling Cryocooler operating at 77K plays a crucial role in freeze-fracture devices and freeze-driers used in cryo-electron microscopy. Instead of relying on large quantities of liquid nitrogen (typically 60 to 80 liters per day), this cryocooler offers an efficient and sustainable alternative.
1- Cooling
The Stirling Cryocooler employs a piston and a displacer to cyclically compress and expand helium gas. When the gas is compressed, it becomes hotter, and when it expands, it cools down significantly. This cooling effect is harnessed to achieve and maintain the desired temperature of 77K.
2- Freeze Fracture Devices
In these devices, the Stirling Cryocooler plays a vital role in maintaining a stable and controlled environment at 77K. This low temperature is essential for quickly freezing biological specimens, such as cells or tissues, before they are fractured and examined under an electron microscope. It ensures that the samples remain in their natural state and prevents the formation of ice crystals.
3- Freeze-driers for Cryo-electron Microscopy
Cryo-electron microscopy involves imaging samples at extremely low temperatures to minimize damage and obtain high-resolution images. The Stirling Cryocooler is integrated into freeze-driers to create the necessary low-temperature conditions for rapidly freezing and preserving samples. This process enab
