1. Up to 50L of water sample can be evaporated and concentrated to 50ml without human supervision. After evaporation, there is no need to transfer it to continue the concentration and acid removal process;
2. Up to 4/6/10 samples can be processed simultaneously to meet the needs of large sample concentration users;
3. One click start of unmanned operation, intelligent addition of water sample by the instrument, real-time recording of evaporated amount, automatic addition of concentrated sulfuric acid and acid rush work when reaching the set amount;
4. Using an evaporating dish as an evaporation container eliminates the need for acid transfer and reduces the loss of the test substance;
5. Equipped with power-off protection function, it can continue to work even when powered on without losing data or damaging the sample;
6Far infrared ceramic or graphite radiation heating ensures even heating and avoids splashing of water samples.
