The AC300 is not only perfect for acid cleaning, but also purifies the acid waste. Users only need to activate a checkbox for acid purification in the software. Even without replacing the acid bottle the AC300 automatically extracts waste acid for sub-boiling purification. For the next usage, purified acid is automatically collected into the pure acid bottle. The system is then automatically rinsed with ultrapure water and dried with hot air, which completes the purification process. The cleaner is then ready for its next task.
