Three models from Select Neptune range is designed to facilitate high flow of guaranteed 18.2M?.cm ultra pure water to be used in analytical and life science laboratory applications. The analytical model comes with a low TOC feature, life Science model offers low bacteria, endotoxins facilities and the last model (ultimate) which combines the benefits of the first two models. A feed water source of <20?S/cm is capable of producing between 1.5 and 2 litres of ultra-pure, 18.2M?.cm, purified water per minute. The Select Neptune range produces ultra-pure, 18.2M?.cm water which includes Ion exchange cartridges incorporating monospherical, semiconductor grade mixed bed deionising resin with a low TOC leaching profile and a high activity organic absorption media, using a host of proven technologies. A filter of 0.2?m and microfilter of 0.05?m for life science and ultimate model removes particles, bacteria and endotoxins. The Analytical and Ultimate model has 185nm or photo-oxidising UV to separate organic compounds into smaller charged ionic species which can be kept aside by ion exchange. The range has 254nm UV to reduce bacteria by more than 99%.
