Beschrijving
Sodium sulphite is een watervrij zout van analytische kwaliteit, geleverd met een zuiverheid van min. 98 % volgens p.a.- en ACS-specificaties. Het draagt CAS-nummer 7757-83-7, empirische formule Na₂SO₃ en EG nr. 231-821-4, met een molaire massa van 126.04 g/mol en een dichtheid van 2.63 g/cm³. Beschikbaar van fabrikant Carl ROTH, ondersteunt deze kwaliteit reducerende en zuurstofvangende stappen, de bereiding van standaardoplossingen en algemeen anorganisch laboratoriumgebruik. Hoge zuiverheid samen met de ACS/p.a.-classificatie helpt laboratoria reproduceerbare resultaten te behouden wanneer sodium sulphite wordt ingezet als reagens of referentiemateriaal in analytische en toepassingsgerichte omgevingen.
Dit artikel maakt deel uit van Oplosmiddelen van analytische kwaliteit (p.a.), in Oplosmiddelen.

Questions about Sodium sulphite, min. 98 %, p.a., ACS, watervrij, 500 g, kunststof
What is this article?
Sodium sulphite, min. 98 %, p.a., ACS, watervrij, 500 g, kunststof is the article on this page. Luminix Health distributes Carl Roth for laboratory use. It sits in Oplosmiddelen van analytische kwaliteit (p.a.), inside Oplosmiddelen, in Chemicaliën.
An analytical-grade solvent, often marked p.a., has impurity limits tight enough for classical analysis and for preparing reagents. It is not automatically low enough in UV absorbance for HPLC, and it is not dry enough for a water-sensitive reaction. The grade is the purchase.
A solvent dissolves. The grade says which impurities are low enough for the method. Analytical grade is the ordinary pure solvent. HPLC and LC-MS grades limit the absorbance and the ions that would become peaks or background. A dry solvent has had water removed. A deuterated solvent is for NMR, where the hydrogen signal would otherwise drown the sample. Technical grade is for cleaning and for synthesis that does not need a chromatogram. Identity is on PubChem. Names follow IUPAC. Hazards follow ECHA, the CLP Regulation and REACH.
Which category should I open next?
The category is Oplosmiddelen. The sub-category is Oplosmiddelen van analytische kwaliteit (p.a.). The catalogue is Chemicaliën.
