Methanol, min. 99,9 %, Blotting-Grade, is a laboratory reagent (CAS 67-56-1) with empirical formula CH₃OH and a molar mass of 32,04 g/mol. It is The blotting-grade specification and minimum purity of 99,9 % identify this methanol for laboratory blotting work where a defined liquid reagent is required. is a practical working volume for measuring and mixing. This methanol is offered by manufacturer Carl ROTH as a blotting-grade material. Concentrations and volumes can be planned from the molar mass of 32,04 g/mol and the density of 0,79 g/cm³. The flash point of 9,7 °C and boiling point of 65 °C describe the volatility and thermal behaviour of the liquid. 99,9 % blotting-grade methanol. Product identity is therefore methanol, CAS 67-56-1, CH₃OH, min. 99,9 %, Blotting-Grade, This article is part of Blotting membranes & papers, in Protein biology & Western blot.
