Ultra-Pure Water System Ultra Clear™ TWF
EVOQUA Water Technologies

The Ultra Clear™ TWF is a water purification system which is combining RO technology with the features of Ultra Clear™ systems. This means that the units can be connected directly to a potable water source and that they are available with all options for a ultra pure water system: dual wavelength UV-oxidiser (TOC < 1 ng / l), ultra filtration modules (endotoxin < 0.001 EU / ml) and TOC-monitoring. Product water from the RO can be taken directly out of the tank, too.

Typical application:
Ultra Clear TWF:
AAS, common analysis, standard buffer, GC.

Ultra Clear TWF UV and UV TM:
HPLC, IC, GC, GC / MS, TOC-analysis, ICP and ICP / MS:

Ultra Clear TWF UV UF and UV UF TM:
DNA sequence, RNase DNase free, DNA free, PVR, IVF, 2-D-electrophoresis, critical cell culture, pyrogen sensitive application.
