Millipore Introduces the First Water Purification Solution for Removing Alkaline Phosphatase

Billerica, Massachusetts --- July 24, 2006 --- Millipore Corporation today announced the first laboratory water purification system for the clinical diagnostic market that removes alkaline phosphatase (ALP). By using an Elix® Clinical system with a BioPak™ final filter, clinical chemists and analyzer operators can obtain significantly higher levels of performance for immunoassays. The proliferation of bacterial species in pure water can create interferences because of bacterial ALP released.

Compared with standard clinical feedwater sources, the unique combination of the BioPak filter on an Elix Clinical system effectively removes ALP from purified water. This ultrafiltration method stabilizes baselines and reduces the frequency of calibrations. For the clinical chemist, this increases efficiency and reduces downtime. For the medical technologist, this decreases sanitization costs that generate more stabilized assay results. Additionally, other clinical products soon may include the BioPak filter for improved performance.

The Elix Clinical system’s design combines prefiltration, softening, reverse osmosis (RO), electrodeionization (EDI), polishing and micro-filtration in one package. By providing Type II and Type I water in a single unit, users now can feed analyzers reliably with pure water. The new Elix Clinical systems produce water at flow rates of 35 and 70 L/h. The BioPak disposable ultrafiltration cartridge dispenses ultrapure water for up to three months without a loss of flow rate.
