For devices in which variable volumes can be measured “by eye”, you are entitled to estimate (interpolate) between the finest divisions of any scale on the device. For a graduated cylinder, the finest division is 0.2 mL, for the beaker, it is probably greater than 1 mL,. The volumetric pipetter is not a variable volume device; it only measures the indicated volume; for a 10 mL pipette at the index mark, it is accurate to 0.01 mL What should you write in your lab notebook if you measure 10 mL of a liquid as accurately as you can by eye using each of these devices? a) graduated cylinder b) beaker c) volumetric pipette
