Ultrapure Water System - Type I Lab Water Purifier - 18.25 MΩ·cm - 20 or 30 L/h

The Master Science Ultrapure Water System produces three grades of water from city tap water: RO water for glassware rinsing, deionized water to ASTM Type II quality, and ultrapure water to ASTM Type I quality with 18.25 MΩ·cm resistivity. A dual-wavelength UV lamp lowers TOC and a 5000 D ultrafiltration module removes pyrogens.

A backlit LCD shows RO conductivity, ultrapure resistivity and operating status at the same time. Two production rates are available, 20 and 30 L/h, with an 8 L pressure tank built in.

Key Benefits

• Three grades of water: the Master Science Ultrapure Water System covers RO, Type II and Type I.
• Ready for sensitive tests: very low TOC, endotoxin and nuclease levels.
• Longer cartridge life: KDF pretreatment removes chlorine and heavy metals.
• Constant quality check: online conductivity and resistivity readings.
• Fewer surprises: quality limit alarm and filter change reminders.

Common Laboratory Problems and How This System Helps

How the Master Science Ultrapure Water System addresses lab water issues:
