滴瓶作为盛贮液体试剂的仪器,在各学科的实验室、化验室和研究室里用得很普遍。长期以来,滴瓶一直是用纸制标签。纸制标签虽有一定的优点,但经常被试剂污染或腐蚀,致使字迹模糊。另外,擦洗滴瓶时,往往将标签纸弄脏或弄坏,以致更换标签,给实验工作人员带来很多麻烦。为此,我们试图在滴瓶上制作一种免除上述缺陷的永久性标签。通过实验,获得较好效果。 Dropping flasks are used as reagents for storing liquid reagents. They are widely used in laboratories, laboratories, and laboratories in various disciplines. Dropping bottles have long been labelled with paper. Although paper labels have certain advantages, they are often contaminated or corroded by reagents, causing blurred writing. In addition, when scrubbing a drop bottle, the label paper is often soiled or damaged, resulting in replacement of the label, which brings a lot of trouble to the experimental staff. For this reason, we tried to make a permanent label on the dropping bottle that was free of the above defects. Through experiments, better results are obtained.
