Hplc grade water
Manufactured by Samchun
Sourced in United States
HPLC-grade water is a high-purity water designed for use in high-performance liquid chromatography (HPLC) applications. It is carefully filtered and treated to remove impurities that could interfere with HPLC analyses.

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.
