Operating Manual
Replacement Filters

The LabTower EDI pure water system is a reaction to the continually increasing requirements

that water of ultrapure quality must fulfil, the increasingly strict demands resulting from technological advances and the need for user-friendly systems and complete solutions.

LabTower EDI systems have been solely and specifically designed to excel in the intended use, which is to produce sterile filtered pure water free of particles, salts and organic compounds. To benefit from the long possible service lives of the high-quality purification media, feed the pure water system with water which has been subjected to an upstream pre-treatment step(reverse osmosis, ion exchange or distillation),
