The Carr index (Carr's index [1] or Carr's Compressibility Index [2]) is an indicator of the compressibility of a powder.It is named after the scientist Ralph J. Carr, Jr. The Carr index is calculated by the formula =, where is the freely settled bulk density of the powder, and is the tapped bulk density of the powder after "tapping down".

Due to the microprocessor control and a number of interfaces, automatic refractometers are able to communicate with computers or other measuring devices, e.g. density meters, pH meters or viscosity meters, to store refractive index data and density data (and other parameters) into one database.
The chemical reactions of dimethylacetamide are typical of N,N-disubstituted amides. Hydrolysis of the acyl-N bond occurs in the presence of acids: . CH 3 CON(CH 3) 2 + H 2 O + HCl → CH 3 COOH + (CH 3) 2 NH 2 + Cl −
Phenacetin (/ f ɪ ˈ n æ s ɪ t ɪ n / ⓘ; acetophenetidin, N-(4-ethoxyphenyl)acetamide [1]) is a pain-relieving and fever-reducing drug, which was widely used following its introduction in 1887. It was withdrawn from medicinal use as dangerous from the 1970s (e.g., withdrawn in Canada in 1973, [ 2 ] and by the U.S. Food and Drug ...
A 0.5 McFarland standard is prepared by mixing 0.05 mL of 1.175% barium chloride dihydrate (BaCl 2 •2H 2 O), with 9.95 mL of 1% sulfuric acid (H 2 SO 4). [ 1 ] Now there are McFarland standards prepared from suspensions of latex particles, which lengthens the shelf life and stability of the suspensions.
