Ultrapure Water System with UV and Ultrafiltration

带紫外和超滤的超纯水系统

LC-MS, proteomics and endotoxin-sensitive cell work need water free of organics and pyrogens as well as ions. This system adds a 5,000–13,000 Da ultrafilter to dual UV, delivering 18.2 MΩ·cm, TOC below 2–5 ppb and endotoxin typically under 0.001 EU/mL at 0.5–2 L/min. Feed with RO or distilled water.

Resistivity: 18.2 MΩ·cm at 25 °C
Total organic carbon: < 2–5 ppb
Endotoxin: < 0.001 EU/mL typical
Ultrafiltration cut-off: 5,000–13,000 Da
Flow rate: 0.5–2 L/min
