where to buy Uranyl acetate in Chennai Near Me

Uranyl acetate (UO2(CH3COO)2·2H2O) is the acetate salt of uranyl and is a yellow-green crystalline solid made up of yellow-green rhombic crystals and has a slight acetic odor. This compound is a nuclear fuel derivative, and its use and possession are sanctioned by international law.

Uranyl acetate is extensively used as a negative stain in electron microscopy.Most procedures in electron microscopy for biology require the use of uranyl acetate. Negative staining protocols typically treat the sample with 1% to 5% aqueous solution. Uranyl acetate staining is simple and quick to perform and one can examine the sample within a few minutes after staining. Some biological samples are not amenable to uranyl acetate staining and, in these cases, alternative staining techniques and or low-voltage electron microscopy technique may be more suitable.

1% and 2% uranyl acetate solutions are used as an indicator, and a titrant in stronger concentrations in analytical chemistry, as it forms an insoluble salt with sodium (the vast majority of sodium salts are water-soluble). Uranyl acetate solutions show evidence of being sensitive to light, especially UV, and will precipitate if exposed.

Uranyl acetate is also used in a standard test—American Association of State Highway and Transportation Officials (AASHTO) Designation T 299—for alkali-silica reactivity in aggregates (crushed stone or gravel) being considered for use in cement concrete.
