Good quality quartz glass material , high accurate , many sizes
Cylinder (graduated cylinder, measuring cylinder or graduated glass) is used for measuring liquid a glass instrument. Cylinder is measure liquid volume of the instrument. Specifications can be measured with the biggest capacity (ml) said that commonly used 10 ml, 25 ml, fifty ml, 100 ml and 250 ml, 500 ml and 1000 ml, etc. The outer wall scale are ml for unit, 10 ml quantity Jane every small division said 0.2 ml, and fifty ml cylinder every small division said 1 ml. Visible cylinder is bigger, the more coarse, its accuracy pipe diameter is smaller, the line of sight of the deviation caused by reading error is bigger also. So, in the experiment should be taken according to the volume of a solution, as far as possible choose can take a quantity of the minimum specifications of the cylinder. Points measuring time can cause the error. Such as quantity take 70 ml liquid, should choose 100 ml cylinder.
