背景技术Background technique
目前，校园实验室量取一定量液体过程一般有很多种方法，如直接倾倒法，用量筒接收，这操作过程中稍不注意就会有会有液体的损失，如药品有腐蚀性更会危害身体健康，既操作复杂误差也很大。另一种方法即利用市场出售的移液管，但其需要与洗耳球配合使用，且使用前需要润洗，造成药品浪费；且上述两种方法均需人为读数，不可避免的存在系统误差。另一市售量取液体药品的仪器移液枪虽避免了人工读数以及药品浪费，但是在操作上不注意就会卡住内部机械装置而损坏了移液枪，而且只能量取1～1000微升的液体，不能被广泛使用。At present, there are generally many methods for measuring a certain amount of liquid in campus laboratories, such as direct dumping method, receiving with a graduated cylinder. If you are not careful during this operation, there will be liquid loss. If the medicine is corrosive, it will be more harmful. Good health, not only complex operation, but also large errors. Another method is to use a commercially available pipette, but it needs to be used in conjunction with the ear-washing ball, and it needs to be rinsed before use, resulting in waste of medicines; and the above two methods require manual reading, which inevitably leads to systematic errors . Another commercially available instrument pipette for taking liquid medicines avoids manual readings and waste of medicines, but inadvertent operation will jam the internal mechanical device and damage the pipette, and it can only measure 1-1000 micrometers. Liters of liquid cannot be widely used.
