Approximate Overflow Volume: 5mL

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 Durex* borosilicate glass, each tube is heat treated at temperatures exceeding 500°C (932°F) immediately before packing, which eliminates contamination, reduces breakage, and increases strength. 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.
