هل فيه مرجع بيوضح العملية دي
Hello dear, where can I find a reference to this procedure?
Dear, is methanol the best cleaning solution? Can a 5% Extran solution and then distilled water be used in ultrasound?
It is the first time to hear about Extran solution for vials cleaning,, Generally you should use HPLC grade solvent, preferable to be low cost
