微孔滤膜使用前一般先于灯光下检查微膜是否完整无破损,如果已破损,则废弃,对于一些有针孔状的小点,能透光或几乎能透光的微膜,为确保过滤质量,我们配制了修补微膜的溶液,经多次使用效果良好。现介绍如下: 取冰醋酸1mL,加无水乙醇10ml,加φ150mm废滤膜1张,搅拌溶解,即得乳白色粘稠液体。 Microporous membrane before use generally check before the light is intact micro-membrane, if damaged, it is discarded, for some small points with a pinhole, can be transparent or almost light-permeable micro-film, to ensure that Filter quality, we prepared a solution to repair the micro-membrane, after repeated use of good results. Are introduced as follows: Take glacial acetic acid 1mL, add anhydrous ethanol 10ml, plus φ150mm waste filter 1, stirring to dissolve, milky white viscous liquid.
