The Elix® Clinical system with a BioPak final filter is a laboratory water purification system that removes alkaline phosphatase (ALP) from purified water. This ultrafiltration method stabilizes baselines and reduces the frequency of calibrations. 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.
