LABORATORY SIZE CARTRIDGE DE-IONIZER GIVES touwtdfiwL WATER
The ILLCO-WAY Throw-Away Cartridge De-Ionizer consists of a clear plastic column containing mixed-bed ionXchange resins. The mixed-bed ionXchange process will re move all dissolved solids (including, in our Research Model, silica and CO2) so that the effluent is pure enough for the finest analytical purposes. The Cartridge is used also to reduce the interfering ions often found in distilled water. The column is clamped in a bracket, as shown, with tubing and valves to connect to any tap or other water supply. ILLCO-WAY Resins used contain a color indicator which changes from purple to yellow as the resins become exhausted, showing when a fresh Cartridge is needed.
RESEARCH MODEL Removes all ionizable solids including silica and CO2. Average in ef fluent less than 0.5 ppm. total solids. Capacity, 450 grains as CaCOa. Flow Rate, 5 gph. max. Price, $12.50 Bracket, extra, $7.50
UNIVERSAL MODEL Removes all ionizable solids, except silica and CO2. Suitable for general pure water needs. Capacity, 900 grains as CaCOa. Flow Rate, 5 gph max. Price, $9.75 Bracket, extra, $7.50
