A 50% savings in paper can mean hundreds or thousands of dollars in the life of a record er. Five-inch charts are hand ier too for notebooks, reports orfiles. And in round-the-table conferences, smaller charts can be set side by side, giving more data and less clutter.
1 & 2 c h a n n e l v e r s i o n s use same 5-inch chart paper; 1% limit of error and 1 or 2% second full-sea le balanc ing time; chart speeds from H inch per hour to 16 i n . / m i n . ; prices from $ 3 6 5 ; numerous options described in Varian literature. Write the Instru ment Division.

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 CaC03. Flow Rate, 5 gph. max. Price, $12.50 Bracket, extra, $7.50
UNIVERSAL MODEL Removes all ionizable solids, except silica and CO2. Suit able for general pure water needs. Capacity, 900 grains as CaCCh. Flow Rate, 5 gph max. Price, Î9.75 Bracket, extra, J7.50
