这些文化管抗化学侵蚀和风化。内容不会释放出污染的解决方案。硼硅还可以防止在实验室测试中pH值的变化。I型制造，B类硼硅玻璃，每管加热，在温度超过500 C（932 F°°）立即在包装之前，消除了污染，增加了强度，减少破损。管超过USP I型规格。管的底部和顶部特征全面火抛光无粗糙的边缘。这些管子的尺寸规格是可靠的严格控制，统一的结果。管清洁密封在一个方便的包装以防止灰尘和其他微粒污染。管47729-566也称达勒姆管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. Tube 47729-566 is also known as a Durham tube.
