在化学试剂加好以后,要进行震荡提取,原来都用两手握管4-6支,上下震荡.我们将比色管架稍为改进了一下,使管架的两端木板稍低于比色管盖上盖后顶端之高度,药品加完后盖上盖,以一块木板一面钉上橡皮,复在顶上,用橡皮管扎紧(如图左),然 After the addition of chemical reagents, shaking extraction is required. The original tube is held between two and four tubes with two hands and shakes up and down. We improve the colorimetric tube rack slightly to make the two ends of the tube rack slightly lower than the colorimetric tubes. Cover the height of the top of the lid, fill the lid after adding the medicine, and use a rubber on one side of the lid to glue it on the top of the lid and glue it with a rubber tube (as shown in the left).
