Culture Tubes

Soda-lime glass Durham tubes are small, cylindrical glass tubes commonly used in laboratories, particularly in microbiology. They are made from soda-lime glass, which is a type of glass composed mainly of sodium oxide (soda), calcium oxide (lime), and silicon dioxide (silica). These tubes are typically placed inside test tubes to capture gas produced during microbial fermentation or other chemical reactions. Soda-lime glass is known for its durability, chemical resistance, and affordability, making these tubes ideal for routine lab work.
