量筒是量度液体体积的仪器.量筒主要用玻璃,少数(特别是大型的)用透明塑料制造.它规格以所能量度的最大容量(m L)表示,常用的有10 m L、25m L、50 m L、100 m L、250 m L、500m L、1000 m L等.外壁刻度都是以m L为单位,10 m L量简每小格表示0.2 m L,而50 m L量筒每小格表示1m L.如图1,可见量筒
Measuring cylinder is mainly used to measure the volume of liquid equipment. Measuring cylinder is mainly made of glass, a small number (especially large) made of transparent plastic.It specifications to measure the maximum capacity (m L), commonly used 10 m L, 25m L, 50 m L, 100 m L, 250 m L, 500 m L, 1000 m L, etc. The outer wall graduations are in milliliters, with a 10 mL volume representing 0.2 mL for each cell and a 50 mL measuring cylinder for each Grid said 1m L. Figure 1, we can see the graduated cylinder
