Ultra pure water purification unit for laboratory
max. 2 L/min, 18.2 MΩ.cm | NEPTUNE PURITE

The Select Neptune range provides a high flow of guaranteed 18.2MΩ.cm ultrapure water for analytical and life science laboratory applications.
Three models are available in the range: Analytical, featuring a low TOC specification; Life Science, offering low bacteria, endotoxins and RNases/DNases specification; and Ultimate, which combines the benefits of both the Analytical and Life Science models. Each unit produces between 1.5 and 2 litres of ultra-pure, 18.2MΩ.cm, purified water per minute from afeedwater source of <20μS/cm.
The range utilises a number of proven technologies to produce ultra-pure, 18.2MΩ.cm water, including:
- Ion exchange cartridges incorporating monospherical, semiconductor grade mixed bed deionising resin with a low TOC leaching profile and a high activity organic absorption media.
- A 0.2μm filter and 0.05μm microfilter (Life Science and Ultimate) to remove particles, bacteria and endotoxins.
- 185nm or photo-oxidising UV to cleave organic compounds into smaller charged ionic species that can be removed by ion exchange (Analytical and Ultimate).
- 254nm UV to reduce bacteria by more than 99%.
