- Leak Prevention: The water seal prevents vapors from escaping the system, which is essential to maintain distillation efficiency and ensure safety, as alcohol vapor can be flammable and dangerous if released into the environment.
- Pressure Maintenance: Helps maintain the internal pressure of the distillation system, which can be crucial for controlling the distillation process and the quality of the final product.
- Contaminant Containment: The water seal can act as an additional barrier against external contamination, maintaining the purity of the distillate.
