DURHAM TUBES

Durham Tubes are small size tubes used within fermentation tubes to detect and collect gas produced by microorganisms during fermentation. Made from clear neutral glass, these tubes provide good visibility for observing gas accumulation during microbiological testing.
The tubes are autoclavable and suitable for repeated laboratory applications where sterilization is required. Their transparent construction allows easy observation of the captured gas, while the rounded bottom provides a suitable shape for gas collection. Properly polished edges offer a smooth finish for convenient laboratory handling.
With a length of approximately 25-27 mm and a diameter of 6-7 mm, Durham Tubes are designed for use in fermentation tests where gas production serves as an important indicator of microbial activity. They are applicable across chemical, biological, microbiology, diagnostic and industrial laboratories. Their simple design makes them useful for routine fermentation studies and other laboratory procedures requiring visual detection of gas production by microorganisms.

Designed to capture gas produced during microbial fermentation, these small neutral glass tubes are suitable for routine use in microbiology, diagnostic and laboratory applications.
