The LN2 trap effectively removes moisture and contaminants from the vapor stream, ensuring a clean and efficient vacuum environment during lyophilization. By capturing and condensing water vapor and other volatile substances, it prevents them from reaching the vacuum pump, thus maintaining a stable and robust vacuum level. This results in improved drying efficiency and reduced drying time.
The LN2 trap serves as a protective barrier for the vacuum pump by preventing moisture and volatile substances from entering and potentially damaging the pump. By removing these contaminants before they reach the pump, the LN2 trap prolongs the pump's lifespan, reduces maintenance requirements, and minimizes the risk of pump failure or degradation.
In processes involving the use of volatile solvents, the LN2 trap aids in their condensation and collection. It prevents the solvents from entering the vacuum system and ensures safe and efficient removal. This is particularly important in pharmaceutical and chemical industries where the handling of volatile solvents is common.
