我们在检验室工作中,往往感到玻片的消耗很大。过去用碱水煮沸清洁,经过3—5次后,玻片上即起了很多花纹,而不能再作油镜的涂片,为了减少消耗,增加玻片的使用次数,我们想出了一个简便的方法,主要是避免直接煮沸,可以增加使用次数三倍以上,如操作小心,则更可增加使用次数。兹将这个方法介绍如下:一、每次作油镜检查后的玻片,浸入煤油中,待积存相当数量时,将煤油倾入另一容器内,煤油
When we work in the laboratory, we often feel that the slides are very expensive. In the past, it was boiled with alkaline water to clean it. After 3-5 times, many patterns appeared on the glass slide, and it could not be used as a smear of the oil mirror. In order to reduce the consumption and increase the number of slides used, we came up with a simple one. The method is mainly to avoid direct boiling, which can increase the number of times of use more than three times. If the operation is careful, it can also increase the number of uses. This method will be described as follows: 1. Each time a glass slide is inspected for oil immersion, it is immersed in kerosene. When considerable quantities are to be accumulated, kerosene is poured into another container.
