Bonjour, Quelle est la différence entre la référence 32205-1L-M et la référence 32221-1L-M? Merci
1 answer-
These products are physically identical with the same minimum purity specification. Product 32205-M is reagent grade which is suitable for general lab applications. It meets some of the analytical specifications of European Pharmacopoeia and testing includes trace analysis. Product 32221-1L-M is Puriss p.a. grade meaning the testing is also extensive and includes trace analysis. The quality of these products is comparable.
