在做观察植物细胞的有丝分裂实验时 ,把解离根尖细胞用过的盐酸溶液用试剂瓶收集起来 ,密封保存备用。把洋葱根尖放进盛有龙胆紫溶液的玻璃皿中染色时 ,不仅把根尖细胞染成紫色 ,而且也把玻璃皿染成紫红色 ,很不易洗涮干净。实验完毕 ,可用镊子夹棉球蘸盐酸溶液在污染过的玻璃 While observing the mitosis experiment of plant cells, the hydrochloric acid solution used to dissociate the root tip cells is collected in a reagent bottle, sealed and stored for use. The onion root into the gentian violet solution in a glass dish staining, not only the root tip cells dyed purple, but also the glass dish dyed purple, it is not easy to wash rinse. The experiment is completed, available tweezers tampons dipped in hydrochloric acid solution in the contaminated glass
