Benzoic Acid 250g Benzoic acid, C6H5COOH, is a colourless crystalline solid and a simple aromatic carboxylic acid. It occurs naturally in many plants and serves as an intermediate in the biosynthesis of many secondary metabolites.
Barium Nitrate 250g Barium nitrate has a chemical formula Ba(NO3)2. It exists as a white solid at room temperature and is soluble in water. Minimum Assay: >99.0 % Molecular Formula: Ba(NO3)2 Molecular
Ammonium Iron (II) Sulphate 500g Ammonium iron(II) sulphate, or Mohr's salt Minimum Assay (Oxidimetric): 99.9 - 100.23% Molecular Weight: 392.13 g/mol Melting Point: 100-110 ªC Chloride (
Ammonium Acetate 500g Ammonium Acetate is a white solid and is often used with acetic acid to create a buffer solution. Minimum Assay: >97% Molecular Formula C2H7N02 Molecular Weight 77.08 g/mol
Acetic Anhydride 500ml Acetic acid, also known as ethanoic acid, is widely used as a reagent in organic synthesis. It is a colourless liquid that smells strongly of acetic acid, formed by its reaction with moisture in the air.
This hi-precision weighing scale is housed in an impact-resistant ABS plastic case with a stainless steel weighing pan, a permanently attached hinged plastic draft shield, levelling bubble and adjustable feet. It is an easy to use, precise scale w
