Frequently Asked Questions
Q: What are borosilicate glass Durham tubes used for in the lab?
A: Borosilicate glass Durham tubes are small, inverted tubes placed inside larger culture tubes to collect and measure gas produced during fermentation. They are widely used in microbiology labs for bacterial fermentation studies, coliform and Enterobacteriaceae testing, yeast fermentation experiments, food safety testing, and classroom science activities. Their heat and chemical resistance makes them reliable for repeated sterilization and use.
Q: Are these Durham tubes reusable, and how should I clean them?
A: Yes, these borosilicate glass Durham tubes are fully reusable. After each use, rinse them thoroughly with water, then clean with an appropriate laboratory detergent. They can be autoclaved or placed in a drying oven for sterilization thanks to their heat-resistant borosilicate glass construction. Always inspect for chips or cracks before reuse to ensure accurate results.
Q: What size are these Durham fermentation tubes?
A: Each Durham tube measures 3.00 × 0.60 × 0.60 cm (approximately 1.18 × 0.24 × 0.24 inches). This small size is standard for use as inverted gas collection tubes within larger test tubes or culture vessels in microbiology and fermentation experiments.
