滤纸为各实验室不可缺少的用品,但在我国截至目前为止,滤纸的供应大部依靠进口,因此价格很高。今年初我们为了响应精简节约的号召,采用了代用品以解决工作中的困难,就是用国产优质的纸来代替滤纸。经过了一个多月的试验,现获得成功。我们所采用的是市售名为「冰玉宣」的一种字画纸,起初我们买来后就直接应用,结果不好。 Filter paper is an indispensable item for all laboratories. However, in China so far, most of the supply of filter paper depends on imports, so the price is high. Earlier this year, in response to the call for streamlining and saving, we used substitutes to solve the difficulties in our work. We replaced the filter paper with high-quality paper made in China. After more than a month of trials, it has been successful. What we have used is a type of calligraphy and painting paper called “Bing Yu Xuan”, which was originally applied directly after we bought it. The result was not good.
