Product features 1. Synchronously working with heating by dry bath in the bottom and nitrogen blowing on the surface accelerates liquid evaporation and sample concentration. 2. The position of gas needle in air cavity can be adjusted to suit for different types of tubes. 3. The height of the air cavity can be adjusted. The length of a standard gas needle is 150mm. 4. Gas needle is controlled independently. Separately blow of each needle and flow regulating of each needle are available to avoid gas waste. 5. The entire equipment can be put into ventilation cabinet when the concentration sample in toxic solvents. 6. Built in overheat protection, automatic fault detection and fault beep alarm devices. 7. LED display immediate temperature and diminishing time. Operation is simple and convenient. 8. Nitrogen sample evaporator configures air cavity and adjustable bracket.
