显微镜是一种精密、贵重的光学仪器,是生物学教学中最基本的实验工具。如果使用和保管不善,常易发生种种故障,影响实验的正常进行。因此,除平时注意使用、保管外,还应定期擦洗,发现问题立即修理,以免影响实验教学和延长其使用寿命。检修时的工具及药品材料 1.工具尖头镊子,洗耳球,专用旋具或尖咀钳,大号、中号及小号螺丝刀,软木条(可用牙签代替),培养皿(直径12厘米,盛装二甲苯用;直径18厘米,盛装卸下的零部件用)二副,蓬头
Microscope is a kind of precision, expensive optical instrument, which is the most basic experimental tool in biology teaching. If the use and mismanagement, often prone to failure, affecting the normal conduct of the experiment. Therefore, in addition to the usual attention to use, custody, but also regular scrubbing and found that the problem immediately repaired, so as not to affect the experimental teaching and to extend its service life. Tools and medical materials for maintenance 1.
