Pack of 10 pcs Durham Tubes

Durham tubes are primarily used for conducting bacterial sugar fermentation tests, especially for the identification of enteric bacteria such as Escherichia coli. They are used to determine whether bacteria produce gas during the fermentation process of known sugars. Durst tubes are typically made of glass and have a slender shape with precise calibration markings. In the experiment, a bacterial sample is inoculated into a Durst tube containing a specific sugar substance. The presence of gas bubbles or gas accumulation in the tube indicates the bacteria's ability to ferment sugars. This method provides valuable information about bacterial metabolic characteristics and helps in the identification of bacterial species.

杜氏管主要用於進行細菌糖發酵測試，特別是用於大腸桿菌等腸道細菌的鑑定。 它們用於確定細菌在已知糖的發酵過程中是否產生氣體。 Durst 管通常由玻璃製成，形狀細長，並帶有精確的校準標記。 在實驗中，將細菌樣本接種到含有特定糖物質的Durst管中。 管中氣泡或氣體積聚的存在表示細菌發酵糖的能力。 該方法提供了有關細菌代謝特徵的有價值的信息，並有助於細菌種類的鑑定。
