通用离心机试管,为防止破碎,可采取以下措施: 一、离心用试管或瓶,选用硬质玻璃材料,均匀退火。表面不应有划痕、柳纹、缺损和气泡等疵病。壁厚应均匀,外径应一致,最好与隔架留有0.5毫米左右的双面间隙。运输、使用,保管过程中应避免磕碰。二、将离心试管放入冰箱和恒温箱内进行温差试验。温度可控制在0℃。C和40℃。再用水代替溶液在离心机内做工作转速下的旋转试验,以不破碎为标准进行挑选。
Universal centrifuge tube, in order to prevent fragmentation, can take the following measures: First, centrifuge tubes or bottles, the choice of hard glass materials, uniform annealing. The surface should not be scratched, Liu Wen, defects and bubbles and other flaws. Wall thickness should be uniform, the outer diameter should be consistent with the best shelves left about 0.5 mm double-sided gap. Transport, use, storage process should avoid bump. Second, the centrifugal test tube into the refrigerator and incubator temperature difference test. Temperature can be controlled at 0 ℃. C and 40 ° C. Replaced with water instead of the solution in the centrifuge to do the work under the rotation speed test, to not be broken as the standard selection.
