Cold Trap devices are commonly used in vacuum systems and chemical laboratories. Their primary purpose is to capture or remove gases or evaporable substances by condensing them into a liquid state. Cold traps are particularly used to prevent the entry of hot vapor into the pumps during the operation of vacuum pumps.
The working principle of cold traps relies on the low temperature of the refrigerant inside, which allows gases or evaporable substances to transition into a liquid state. This condensation occurs as a result of the cooling and condensation of gas molecules that come into contact with the refrigerant inside the trap. Thus, the liquefied gases or substances remain trapped inside the device and are removed without causing damage to the vacuum system's pump.
The Labo CT-400 and CT-800 models have been specifically developed by Labo's R&D department to perform such tests according to specific needs.
