Description
技术领域 technical field
本实用新型涉及生物实验室用器材技术领域，特别涉及一种生物教学用试管。The utility model relates to the technical field of biological laboratory equipment, in particular to a test tube for biological teaching.
背景技术 Background technique
传统的试管一旦在管口塞上试管塞后，试管内就形成一个密闭环境，空气无法流通到试管内。因此传统的带塞试管无法用于细菌(尤其是需氧菌)的培养试验。而敞口试管进行细菌培养，需要面临着细菌传播的危险，或者培养物质在培养的过程中外泄的情况发生。Once the traditional test tube is plugged with a test tube stopper, a closed environment is formed in the test tube, and air cannot circulate into the test tube. Therefore traditional test tubes with stoppers cannot be used for the culture test of bacteria (especially aerobic bacteria). However, the open test tube for bacterial culture needs to face the danger of bacterial transmission, or the leakage of cultured substances occurs during the culture process.
