| 35 | The U-100 and U-50 columns are identical because both use a 0.01 mL graduation; they differ in barrel capacity and therefore in the physical spacing of the marks, which is the point of the U-50 syringe. The U-40 column is the hazardous one: an identical reading corresponds to two and a half times the volume. | 36 | The U-100 and U-50 columns are identical because both use a 0.01 mL graduation; they differ in barrel capacity and therefore in the physical spacing of the marks, which is the point of the U-50 syringe.
