Glass Culture Tubes


Disposable Glass Culture Tubes

These culture tubes are resistant to chemical attack and weathering. Contents will not leach out and contaminate solutions. Borosilicate also prevents pH change in laboratory tests. Manufactured from Type I, Class B borosilicate glass, each tube is heat-treated at temperatures exceeding 500°C (932°F) immediately before packing, which eliminates contamination, increases strength, and reduces breakage. Tubes exceed USP Type I specifications.

Tubes feature well-rounded bottoms and fire-polished tops free of rough edges. Dimensional specifications of these tubes are rigidly controlled for reliable, uniform results. Tubes are clean-sealed in a convenient dispensing package to keep them free from dust and other particulate contamination. The 6 x 50 mm culture tube is also known as a Durham tube.
