Ultra-pure Water Purifier - 18.2 MΩ·cm Lab Water System - 20, 40 or 60 L/h

The Master Science Ultra-pure Water Purifier makes 18.2 MΩ·cm ultra-pure water and primary RO water at the same time from tap water. A single-pass RO stage with high ion rejection feeds a large-capacity DI ion-exchange unit, all controlled automatically and shown on an LCD.

Three output rates (20, 40 and 60 L/h) are each offered in four versions: Standard, V for low TOC (2 ppb), F for endotoxin and nuclease removal, and VF combining both.

Key Benefits

• Two water grades together: the Master Science Ultra-pure Water Purifier gives Type I and RO water.
• Choose the right purity: four versions for general, trace organic and bioscience work.
• Large DI capacity: fewer cartridge changes.
• Automatic control: LCD with system status.
• Compact: built-in tank in a 273 mm wide body.

For a unit with UV and ultrafiltration as standard, see the Master Science ultrapure water system.

Common Laboratory Problems and How This Purifier Helps

How the Master Science Ultra-pure Water Purifier supports sensitive analysis:

• Contamination peaks in trace analysis: 18.2 MΩ·cm water with TOC down to 2 ppb.
• Endotoxin and nucleases in bioscience work: F and VF versions remove them.
• Separate systems for RO and ultra-pure water: one unit supplies both.
• Low tap pressure: optional pre-boost device.
