Purified water for clinical analysers

Analyser feed systems are specifically designed to produce NCCLS Type I reagent water, straight from tap water, for direct feed to clinical analysers

Millipore's AFS-8 and AFS-16 analyser feed systems are specifically designed to produce NCCLS Type I reagent water, straight from tap water, for direct feed to clinical analysers.

Producing up to 16l/h, AFS systems produce water that is ideal for performing a variety of on-board applications, such as reagent reconstitution, serum dilution, probe rinsing and cuvette washing.

AFS systems have Class One medical device status (under FDA citation 21CFR 862.2050) and employ multiple purification and monitoring technologies to ensure water quality.

The first purification step is the Progard 3 pretreatment pack, which contains activated carbon and depth filtration to reduce organics and particulates, as well as an anti-scaling agent to protect the reverse osmosis membrane from premature wear.

Secondly, reverse osmosis removes the principle ionic and organic contaminants and colloidal silica, then the Q-Gard AFS purification pack eliminates the remaining ionic contaminants.

Finally a microfilter is used to remove bacteria.

Additionally, the AFS-8D and AFS-16D systems contain a built-in degasser for removal of gases such as oxygen and nitrogen, which would otherwise form bubbles at the typical clinical assay temperature of 37C, therefore interfering with optical measurements in clinical analysers.

AFS systems are designed for ease of use with easy-to-replace purification packs and automatic cleaning cycles.

Furthermore high-precision, in-line resistivity monitoring guarantees consistently pure water quality, ensuring continuous, effective and efficient operation of clinical analysers.
