在检验室里,使用吸管的地方很多,但大多数检验工作者,在吸取各种液体时,仍多采用口吸法。该法除存在着不卫生的缺点之外,如吸取烈性药液(包括挥发性药液、强酸、强硷等)时,稍一不慎,即有发生危险的可能;如吸取合菌液体,也有误将菌液吸入,而遭受感染的危险。因此,很多同志都在研究改进吸管的吸取方法。我在技术革新运动的热潮鼓舞下,由于党和领导上的支持,试制出一种自动吸取器,现将其制作和使用方法介绍于下,以供大家参考,并请提出进一步改进,构意兄。、。一、制作方法·1.取25—30厘米畏的和玻管一支(与吸管粗釉相仿),在洒精灯火上封其一端(称顶端),他端(称尾
There are many places to use pipettes in the laboratory, but most test workers still use the method of mouth suction when taking in various fluids. In addition to the law there are unhygienic shortcomings, such as the absorption of strong liquid (including volatile liquid, strong acid, strong base, etc.), the slightest mistake, that there is the possibility of danger; such as drawing compound bacteria liquid, Also mistakenly inhaled bacteria, and the risk of infection. Therefore, many comrades are studying ways to improve the suction of drinking straw. Inspired by the technological innovation movement, due to the support of the party and the leadership, I tried to create an automatic extractor. Now I introduce its production and use methods for reference, and I propose further improvements. Brother . First, the production methods · 1 take 25-30 cm Wei and a glass tube (straw and glaze similar), in the fine light lamp seal the end (called the top), his end
