Labotemp Ultrapure Water Purification System with Ultrafiltration LWS-05 delivers high-purity laboratory water for applications where control of biological contaminants and pyrogens matters. Available in 10, 20, 30, and 40 L/h configurations, the system combines pretreatment, RO purification, ultrapurification, and ultrafiltration within an integrated 8-stage process. It produces water with 18.25 MΩ·cm resistivity at 25°C, while the UF configuration achieves endotoxin levels below 0.001 EU/ml, RNases below 0.01 ng/ml, DNases below 5 pg/ml, and proteases at 0.15 µg/ml. This makes it suitable for pharmaceutical, biochemical, molecular biology, and other sensitive laboratory workflows.
Designed for dependable daily operation, LWS-05 features a 10-inch floating touchscreen with 360° adjustment, a 64-bit microprocessor, and triple online monitoring of feed, RO, and ultrapure water. Switchable circulation helps maintain low bacterial contamination in the ultrapure water loop, while tool-free cartridge replacement simplifies routine maintenance. The system accepts municipal tap water at 5–40°C and 0.1–0.5 MPa pressure and provides RO water with ≤1 µS/cm conductivity at 25°C. Its controlled purification and monitoring make it a practical lab water purification system for demanding research and analytical environments.
