Nitrogen Evaporator

RayKol Auto EVA 12 is a nitrogen blow-down evaporation system that provides automated evaporation of up to 12 samples in parallel with endpoint detection. It uses vortex airflow generated from stable angled nitrogen blow, to constantly disturb the sample surface and lower its vapor pressure in order to gain gently rapid evaporation under water bath heating. Each sample position is equipped with optical sensor to precisely determine endpoint of concentration. User can have real-time monitoring to whole process through built-in touch screen, make it easier to access and observe.

 

Features

• Batch processing, simultaneous evaporation of up to 12 samples in parallel

• Rapid concentration under water bath and nitrogen blowing

• Transparent sink design for observation

• Good compatibility with various sample vials and ajustable blowing angle

• Automatic endpoint detection to avoid over-drying

• Sprinkle rinsing to sample vials to maximize recovery rate
