Water Purification
Devices, filters, cartridges, accessories, and other supplies for use in the purification of water. Products include consumables and replacement parts for use with a variety of water purification systems.
Source or feed water may be tap water, water that is pre-treated by the system, or pretreated water that is drawn from a reservoir or tank. Water systems typically produce water rated as Type I, II, III, or IV.
Type I or ultrapure Type I water is defined by resistivity and TOC levels (total organic compounds, measured in parts per billion (ppb). Type I water is required for ICPMS, AAS, FAAS, GFAAS, HPLC, IC, and ICPAES methods, molecular biology, cell and tissue culture, electrochemistry, and electrophoresis.
Type II water is suitable for ELISA and RIA test methods, buffer and reagent preparation, and spectrophotometry. It also has a specific requirement for resistivity. Type III water is used for media preparation, glassware washing and rinsing, and other non-critical applications. Type IV water is typically used as feed water for Type I and Type II water purification systems.
Replacement water purification parts – filters and cartridges – are key components of these systems and must be changed according to specifications to maintain the promised water quality.
