VWR Culture Tube Glass 15 x 85 mm 1150 Tubes

VWR 47729-574 Culture Tubes are high-quality laboratory vessels designed for a wide range of applications, including cell culture, microbiology, and chemical analysis. These 15 x 85 mm tubes are made from Type I, Class B borosilicate glass, which is known for its excellent chemical resistance, thermal shock resistance, and inertness. This material prevents pH changes in laboratory tests and ensures that the contents of the tube will not leach out and cause contamination.

These tubes are heat-treated at temperatures exceeding 500 °C (932 °F) immediately before packing. This process eliminates contamination, increases the strength of the tubes, and reduces breakage. The tubes feature well-rounded bottoms and fire-polished tops, which are free of rough edges, making them safer and easier to handle. The dimensional specifications of these tubes are rigidly controlled for reliable, uniform results.
