INTRODUCING NANOpeTM.

THE TYPE I WATER SYSTEM WITH

NOlSOrDISPOSABLE CARIRIDGES.NANOpure deionization cartridges, with twice

the rated ion exchange capacity of comparable sys-tems, offer the lowest per liter purification cost-and they require replacement far less often. Thatmeans economy and convenience!

But that's not all. Here are six other soundreasons to select the new NANOpure system:

High Flow Rate. NANOpure delivers 3 litersper minute of pure water with a specific resistancein excess of 10 megohms-cm. That's twice the flowrate of the other popular laboratory system.

Immediate Cartridge Delivery. NANOpure car-tridges are stocked by top laboratory supply dis-tributors throughout the U.S. and Canada to assureavailability and help reduce your stocking problem.

Quantitative PurTity at a Glance. A direct-read-ing in-line resistivity meter is standard equipmentwith each NANOpure system.

Comprehensive Record-Keeping System. EveryNANOpure is supplied with a clipboard and a twoyear supply of log pages designed specifically for

recording of all pertinent purity checks and tests tosatisfy accreditation requirements.
