Results 1–5 of 5 for Wilsonova komora
Wilson’s chamber → Wilsonova komora
Wilson’s chamber is used for detection of radioactive radiation. Wilson’s chamber has a glass cylinder filled with air that has been saturated with water vapour. Radioactive radiation in its way ionises molecules of gas which then function as centres on which water vapour condenses into very small drops, thereupon showing Tyndall’s effect, i.e. is they are visible as a bright trail.
salt fog chambers → slana komora
Salt fog chambers are designed for corrosive atmosphere testing. The samples being tested are inserted into the chamber and then the salt-containing solution is sprayed as a very fine fog mist over the samples. The temperature within the chamber is maintained constant (usually 35 °C). These test chambers are constructed of non-corrosive materials.
salt fog test → ispitivanje u slanoj komori
Salt fog test is an accelerated corrosion test in which specimens are exposed to a fine mist of a solution usually containing sodium chloride (typically 5 %). Other contaminants can be added according to desired conditions. It is mainly used to determine the effectiveness of material finishes and protective coatings on materials. Salt-fog testing is also used to determine the effects of salt deposits on the electrical functions of electronic assemblies.
Soxhlet extractor → Soxhletov ekstraktor
Soxhlet extractor is a laboratory apparatus designed to extract substances with a low solubility in the extracting solvent. The method described by the German chemist Franz von Soxhlet (1848-1926) in 1879 is the most commonly used example of a semi-continuous method applied to extraction of lipids from foods. In the Soxhlet extractor, the sample soaks in hot solvent that is periodically siphoned off, distilled and returned to the sample. During each cycle, a portion of the non-volatile compound dissolves in the solvent. After many cycles the desired compound is concentrated in the distillation flask. The solvent in the flask is then evaporated and the mass of the remaining lipid is measured.
Wagner tube → Wagnerova cijev
Wagner tube or drop catcher impedes the movement of distillate drops from the distillation flask to the condensing chamber.
