Microprocessor-controlled purity monitor provides digital resistivity readings, temperature compensated to 25°. A standby mode recirculates the purified water for 10 minutes every hour of inactivity. Water remains clean and free from recontamination and ready to use when you need it! All components are constructed of extremely inert materials ensuring maximum ionic and organic purity.
Photo of E-Pure™ Cartridge Systems
E-Pure™ Cartridge Deionization Systems produce resistivities up to 18.2 megohm-cm and TOC levels below 10 ppb. Virgin polypropylene water pathways prevent recontamination. Recirculation pump continuously recirculates water throughout the entire system to maintain water purity and reduce the quantity of wastewater required for rinse-up. Wall mounted; completely assembled for easy installation. 1/4-turn quick release canisters allow for easy cartridge replacement. 0.2-micron absolute hollow fiber filter removes bacteria and particulates that could alter your results.

The B-pure Cartridge System provides you the flexibility of designing your own water system. The modular design allows you the ability to add additional holders when the need exists. If you need pure water of less quality than the NANOpure, E-pure, or EASYpure II can produce, the B-pure is the right system for you. Produces up to 4 liters per minute, depending upon feed water quality. Quarter-turn quick release canisters accept most Barnstead cartridges and filters. Allows for the addition of holders, as water needs change. Accepts Pura®-Lite purity indicator or digital purity meter.

The B-Pure™ 1/2 Size Filter Holder (D2772-1) has a natural polypropylene material construction that maintains purity. Filters are easily and quickly replaced with 1/4-turn quick release canisters. Accepts 10" (25.4) cm) pre- and post-filters. Wall mount. Economy Filter Holders (D2772-1E & 1F) accept virtually all 10" (25.4 cm) double, open-ended filters. Can be piped into any water line. Available in 10" and 20" holders. Post-filters for the B-pure 1/2 Size Filter Holder have a pleated, non-leachable construction.
Depending on the deionization system, certain accessories are available. These can be easily added to either new or existing systems to provide the benefits described. Digital Purity Monitor: Provides a direct reading of the resistivity of the water exiting the system. Temperature compensated to 25°C. Fits conveniently into B-pure, as well as any 1/2" (12.7 mm) NPTF opening. Provides a digital reading of actual water purity in megohm-cm, temperature compensated to 25°C. Pura®-Lite: Provides "Go/No Go" indication of water purity.
