Milli q plus reagent grade water system

Manufactured by Merck Group

Sourced in United States

The Milli-Q PLUS reagent-grade water system is a laboratory water purification system designed to produce high-purity water. The system utilizes a multi-stage purification process to remove impurities and contaminants, resulting in water that meets or exceeds standards for reagent-grade applications.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
