Millipore Milli-RX20 water purification system

  • Produces 20L/ hour
  • Type II analytical grade 99% purified water
  • 90-day warranty

Large-volume systems combine reverse osmosis (RO) and patented Millipore Elix electrodeionization technology to produce Type II analytical-grade water. Purify 51/4 to 193/4 gal./hr. (20 to 75L/hr.). Ideal for preparing media, buffers and reagents, and as final rinse for glassware. 

Three-step water purification. ROPak* Pretreatment Pack with antiscaling compound provides primary purification and protects RO membrane. Secondary purification is achieved with a high-recovery reverse osmosis cartridge. Elix module provides final purification. (Cartridges sold separately.)

Elix technology for consistent water quality. Combines ion-permeable membranes, ion-exchange resins, and an electric field to remove ions from water without chemicals.

Small, electric current within the Elix module continuously removes ions and regenerates ion-exchange resins. Removed ions are flushed from system into waste stream that can safely be directed down drain. Provides uninterrupted supply of water of consistent quality. Low-maintenance and lower-energy process removes calcium ions and uses less electricity than traditional distillation equipment.

Easy to operate and maintain. Simple, four-button operation. System status and performance are displayed on two-line alphanumeric LCD. Signals cartridges need replacing or RO-membrane needs cleaning. Automatic RO-membrane flush simplifies maintenance. Alarm signals if system malfunctions and displays help messages. 

This equipment is used and reconditioned. Our technicians test all equipment to confirm that it operates properly and to the manufacturer’s specifications. While we can’t test for a specific analytical application, we will do our best to simulate the conditions under which the equipment will be run. If you have particular testing requirements or requests please let us know and we’ll work with you to make sure these requirements are addressed during testing.

The photos above are representative. Please bear in mind that the equipment shown is currently in storage in our warehouse and that in addition to testing each machine we will clean all the equipment thoroughly prior to shipment. We often have multiple units of each model in stock and sometimes we're unable to feature photos of every single unit. At your request, we can provide photos of the equipment in your order after it has been tested and cleaned.
