Durham Glass Test Tubes
Main Application of the Durham glass test tubes:
It applies to the food industry, yeast factory, brewery, and other units to determine the yeast fermentation efficiency and to conduct bacteria hygiene tests in medicine and fermentation tests on water, milk, and ditch sewage. For example, in bacteriology, the production of lactic acid by the anaerobic decomposition of glycogen in tissues is changed for QS large intestine detection.
Put the calibration catheter upside down into the test tube for multi tube fermentation to determine whether there are deflated bacteria in the water. If there are metabolic deflated bacteria, it will be inverted after a period of culture. Gas can be observed in small durham tubes.
In real life, it is also applied as follows:
1. Equipped with a stopper, we is often used it to observe small insects.
2. Used as Perfume Glass Test Tubes.
