18. Double wavelength (185&254nm) ultraviolet lamp module, restrain bacteria’s increase and reduce TOC.
19. MWCO 5000D ultrafiltration module, effectively eliminate endotoxin, and suitable for precise cell cultivating and IVF.
20. (0.45+0.1)µm double layer PES terminal disinfection filter, assure that terminal pure water is absolutely axenic.

Master-Q series deionized water system (Tap water inlet)

With LCD controlling system, 3 way water quality sensor, timing and quality dispensing, single stage RO system and 1 pump, Master-Q series deionized water system is superior choice of deionized water for general grade experiments.

With tap water inlet, its output ranges from 15 to 30 liters/hour. It can produce single stage RO water and deionized water. The single stage RO water’s ion rejection rate is more than 96%, and the deionized water’s resistivity is more than 16MΩ.cm, near to18.2MΩ.cm. It completely meets the requirements of general chemical or biological experiments for pure water.
