Isopropanol R
Purified water
Вроде как о чистоте в немецком стандарте речь идет. Как-то заказывал реактивы, получил GR, сказали, что-то типа ч.д.а. А что такое R - "ч." или что иное?

Russian translation:чда
Explanation:
R (Reagent Grade) = GR (Guaranteed Reagent) = AR (Analytical grade) = PA (Pure for Analysis) = чистый для анализа



Guaranteed Reagent (GR)
It is the ideal quality for laboratory purposes. Batch to batch reproducibility is specially controlled to guarantee consistent analytical results. The grade is equivalent to Analytical grade (A.R.) Reagent grade (R.G.), p.a. nomenclature of other manufacturers

agree  Leila Usmanova: Скорее всего ч.д.а., потому что эти реагенты используются в аналитических целях. Мой заказчик просит оставлять буквенные обозначения чистоты, принятые в Европейской фармакопее (такие как R, S и т.д. ) без перевода

  -> Спасибо, Лейла. Конечно, оставить оригинальную маркировку всегда полезно.
