在工厂的实验室、医院的化验室都要进行定量分取溶液的操作,使用一般的移液管非但操作速度慢,而且在吸取少量溶液时容易将试液吸入口腔内有碍卫生和健康。在日本九州大学医学部药学科工作的百濑勉1962年介绍过一种快速自动移液管,编译者曾与人合作仿制使用过该装置,具有操作速度快、容积准确等优点。该移液管的结构见图。吸取用的注射器以移液管容量的2～3倍为好,并如图那样把螺丝和螺帽安装好,注射器管内放入弹簧,只要弹簧延伸
In the laboratory of the factory, the laboratory of the hospital carries out the operation of quantitative dispensing of the solution. The use of the ordinary pipette not only is slow in operation but also easy to inhale the test solution into the oral cavity to impede the health and well-being when taking a small amount of solution. In Japan, Kyushu University, Department of Medicine, Biase Mian in 1962 introduced a rapid automatic pipette, the compiler has been used in cooperation with the imitation of the device has the advantages of fast operation, accurate volume and so on. The pipette structure shown in Figure. Suction syringe to the pipette capacity of 2 to 3 times as well, and as shown in the screws and nuts installed, the syringe tube into the spring, as long as the spring extension
