Analytical pure tungsten trioxide is AR tungsten trioxide that can be used as an analytical reagent. It is suitable for a variety of important analysis and general research work. For example, it is commonly used in general laboratories, research institutes and other places to prepare ordinary solution in quantitative analysis. It should be sealed and stored in a dry place.
What is AR?
AR, analytical reagent, is a type of purity of chemical reagents. There are fewer impurities in the AR reagent. And it does not obstruct the analysis and determination. Different drugs have different requirement for purity. And there reagents are often packaging with smaller bottle, such as a 500g/bottle.
Other chemical reagents include guaranteed reagent (GR), chemical pure (CP), laboratory reagent (LR), teaching reagent, ZD, extra pure reagent (EP), chromatographically pure (GC), indicator (ID), biochemical reagent (BR), biological stain (BS), spectral purity (SP), electronic pure (MOS), equivalent reagent (3N/4N/5N), electrophoresis reagent, special reagent and so on.
