MERCK Milli-Q® EQ 7000 Ultrapure Water Purification System

Type 1 Ultrapure Water System for sensitive laboratory applications.

Category: Tag:

To deliver reliable, high-quality scientific results, you require consistently high-quality ultrapure water. The Milli-Q® EQ 7000 ultrapure water system is designed to produce consistent ultrapure water quality [resistivity 18.2 MΩ·cm @ 25 °C; total organic carbon (TOC) ≤ 5 ppb] that can be adapted to each user’s specific application requirements. Plus, a range of intelligent design features make it effortless to dispense water as needed and where needed in the lab.

The Type 1 water purification system that adapts to your laboratory space and science

Flexibility that fits your laboratory. You can choose…

  • – The space-saving setup that works for you: On or under the bench, or up on the wall.
  • – To system-mount or wall-mount the Q-POD® dispenser.
  • – To wall mount the HMI touchscreen or place it on the bench up to 3 m from the system.
  • – The feed water option available in your lab: Elix® electrodeionization (EDI), deionization (DI), reverse osmosis (RO), or distillation.
  • – To adapt the final water quality according to your requirements with our range of Application POD-Pak final filters

Easy and agile Q-POD® ultrapure water dispensing

  • – Select from 3 manual flow rates and one-touch volumetric dispensing.
