众所周知,医院的各种化验检查都是用吸管准确“量取”各种1体(标本和标准试剂等)的。吸管的标量准确与否直接影响检验结果的准确性。因此,吸管的标量是保证检验质量的一个重要环节。以往微量吸管的校正,多数采用水银称量法,操作困难、费时。我们对外径千分尺稍作改进,制成微量吸管 As we all know, the hospital’s various laboratory tests are using straw to accurately “measure” a variety of body (specimens and standard reagents, etc.). Straw scalar accuracy or not directly affect the accuracy of test results. Therefore, the straw scalar is to ensure the quality of inspection is an important part. Previous micropipette calibration, the majority of mercury weighing method, the operation is difficult and time-consuming. We made a slight improvement on the outer diameter micrometer, made of micropipette
