New Automatic Condensation System for Fallout Measurement

Abstract

A continuous evaporation system was developed. Sample water was continuously supplied to rotary evaporator with a tube pump. The tube pump was controlled by water level sensor placed in a sample flask. Condenser was turned upside down, and droplets of water were removed by an aspirator. The merits of the system are as follows, (1) labor saving, (2) no generation of water vapor in a room, (3) fire prevention, (4) 20 L of sample water per day can be evaporated.
