For example, ordinary vodka, gin, rum and tequila have an alcohol concentration typically around 40% alcohol by volume (80 proof), and liqueurs are typically around 20% alcohol (40 proof). [6] Everclear is also used as a household "food-grade" cleaner, disinfectant, or stove fuel alcohol because its fumes and odor are less offensive than ...
A tape head cleaner is a substance or device used for cleaning the record and playback heads of a magnetic tape drive found in video or audio tape machines such as cassette players and VCRs. [1] These machines require regular maintenance to perform properly.
A tincture is typically an extract of plant or animal material dissolved in ethanol (ethyl alcohol). Solvent concentrations of 25–60% are common, but may run as high as 90%. [ 1 ] In chemistry , a tincture is a solution that has ethanol as its solvent.
But when omitting alcohol from a drink you need to consider a range of factors: alcohol adds body and richness to drinks, it balances sweet flavors, and its astringency adds texture.
Alcohol inhalation is a method of administering alcohol directly into the respiratory system, with aid of a vaporizing or nebulizing device or bag. It is chiefly applied for recreational use, when it is also referred to as alcohol smoking, but it has medical applications for testing on laboratory rats, and treatment of pulmonary edema and viral pneumonia.
This means that adding ethanol to a solution disrupts the screening of charges by water. If enough ethanol is added, the electrical attraction between phosphate groups and any positive ions present in solution becomes strong enough to form stable ionic bonds causing DNA to precipitate out of the solution. This usually happens when ethanol ...
Phenol: The phenol used for biochemistry comes as a water-saturated solution with Tris buffer, as a Tris-buffered 50% phenol, 50% chloroform solution, or as a Tris-buffered 50% phenol, 48% chloroform, 2% isoamyl alcohol solution (sometimes called "25:24:1"). Phenol is naturally somewhat water-soluble, and gives a fuzzy interface, which is ...
Ladislaus Reti, a 20th-century historian of science, investigated alchemical recipes involving alkahest and found that no chemical was sufficient in breaking down the wide variety of materials Helmont supposed. Reti points out that in such recipes, an alcohol solution of potassium hydroxide could have been used instead. [5]
