一般描述

Methanol, also known as Methyl alcohol, is a colorless organic solvent commonly used to dissolve substances with high and medium polarity. It is also used as a starting material/solvent for synthesis.

应用

Methanol is used as a solvent:
  • In the mobile phase during the reversed phase for high-performance liquid chromatography (HPLC) analysis.
  • To prepare the stock solution of Fluorescein dye.

包装

M-Bottle for Solvents
As a global leader in lab reagents, we are constantly looking for new ways to optimize the safety of our products. The newly developed 4L solvent bottle design features advanced sealing technology that eliminates leaks to make the handling of solvents safer and more convenient than ever before.
