Description

General description

PrepSolv^™ solvents are tailored to the requirements of preparative HPLC to facilitate scale-up from analytical to preparative separations. With their extremely low evaporation residue (< 1 mg/l) and low water content, they ensure optimal protection for columns.

Application

for preparative chromatography Prepsolv^™

Storage and Stability

Store at +5°C to +30°C.
