How long to expose emulsion with 300 watt light?
The exposure time needed for exposing emulsion with a 300-watt light will depend on factors such as the distance between the light source and the emulsion, the type of emulsion being used, and the specific requirements of the emulsion manufacturer. It is recommended to perform a test strip to determine the optimal exposure time before exposing the entire emulsion.
What is the principle behind the kraut's test for lipids?
The principle behind the Kraut's test for lipids is that lipids form a white emulsion when shaken with sulfuric acid due to the formation of glycerol and fatty acids. The appearance of a white emulsion indicates the presence of lipids in the test sample.
