                                  Detailed introduction

                                  CLRW quality

                                  AFS® systems combine complementary water purification techniques; complete pretreatment, intelligent reverse osmosis (RO), bactericidal UV lamp treatment and a final 0.22 μm filter ensure a reliable and consistent water quality. Water produced by the systems complies with the Clinical and Laboratory Standards Institute® (CLSI) guideline for clinical laboratory reagent water (CLRW). Depending on daily volume needs, different production flow rates are available (8, 16 and 24 L/h).

                                  The systems are designed to fulfill accreditation needs (such as CAP™ 15189 accreditation to the ISO® 15189:2007 standard), and have full monitoring and water quality archiving capabilities that allow storage of up to six months of data. Optional activation of Millitrack® Essential e-Solution allows easy, rapid access to this information and also enhances data management control and provides remote system access.

                                  User friendly & easy maintenance

                                  Robust AFS® systems require little maintenance, which means less analyzer downtime. When maintenance is required, an intuitive icon-based display and a new pack locking system facilitate pack changes. Systems have a small footprint and can be installed wherever it is convenient in the laboratory: on a wall, on or under a bench, or on a cart.
