Deionizers remove dissolved ionic salts and minerals from liquids via ion exchange. The Q-LAB5/10/20-DI model, with ISO9001 and CE certification, offers a 99.0% salt rejection rate. Suitable for laboratory applications, it processes 20 liters per hour from municipal tap water. The resulting ultrapure or RO water has a resistivity of 18.25 mΩ/cm, total organic carbon under 10 ppb, and bacteria levels below 1 cfu/ml.
