Highly Purified Water For Accurate And Reproducible Test Results Water is irreplaceable for functioning of your analyzer. Therefore, the water quality has direct impact on the quality of test results. The OP water treatment systems combine reverse osmosis for effective removal of contaminants with water deionization via ion exchanger resins. The combination of these purification technologies assures a constant and reliable supply of water of highest quality. Your Benefits OP water treatment systems are the perfect balance between quality and economy featuring high quality membranes, prefiltration for membrane protection, and manometric and conductometric controls for easy system monitoring. Further advantages are low running costs and easy maintenance. Your System DiaSys developed a complete line of water purification systems to suit different customer needs. MINI OP100 is an extremely compact system producing 15 Liters purified water per hour and recommended for daily water consumptions of max 30 Liters. OP100 has the same capacity per hour but a higher daily capacity up to 50 Liters per day. OP101+ with identical capacity but higher resin volume is the version for feed water of high hardness. OP202+ and OP302+ are the choice if higher volumes of purified water are needed. OP202+ is recommended for daily water consumption between 50 and 100 Liters and OP 302+ for a daily volume of 50 to 150 Liters. Both systems produce 30 Liters purified water per hour (at 25 °C).
