Medium-RQ Series Deionized Water System (CAT#: STEM-AL-2253-ZJF)

Medium-RQ Series Deionized Water System is designed for producing deionized water for reagent preparation, glassware rinsing, analytical support, and general laboratory processes. The documented series contains 4 model configurations identified as Medium-RQ30, Medium-RQ45, Medium-RQ60, Medium-RQ90. The purification train uses two-stage reverse osmosis, electrodeionization, ion-exchange deionization, terminal membrane filtration with Tap water, temperature: 5-45°C, pressure: 1.0-4.0kgf/cm² as the documented feed-water condition. The stated production and dispensing performance is Output -1st stage RO water: 63 L/h / 93 L/h / 125 L/h / 150 L/h; Output -2nd stage RO water: 30 L/h / 45 L/h / 60 L/h / 90 L/h; Output -deionized water: <30 L/h / <45 L/h / <60 L/h / <90 L/h; Pure water outlet: 3: 1st and 2nd stage reverse osmosis water, deionized water. The principal documented water-quality performance is deionized-water resistivity 10-18.2MΩ·cm, bacteria <0.01CFU/mL, particles <1/mL, second-stage RO conductivity 1-5µS/cm. System operation is supported by LCD control, online water-quality monitoring, data logging, USB data transfer, system alarms, password-protected settings. Model-dependent treatment and dispensing options include terminal sterilizing filter. The documented installation information is Length×Width×Height: 640×540×1110mm / Weight: about 75kg, with AC110-240V, 50/60Hz electrical input and 240W / 360W power. The series supports repeatable laboratory water preparation within the documented feed-water, maintenance, and configuration limits.
