For determining water by distillation. Receivers have a 24/40 ground joint on the sidearm. The 10 mL receiver is graduated, from 0 mL to 1 mL, in 0.1 mL increments, with a maximum scale error of 0.05 mL. Graduation increments from 1.0 to 10.0 mL are 0.2 mL, with maximum scale error of 0.1 mL. The 25 mL receiver is graduated, from 0 mL to 1 mL, in 0.1 mL increments, with a maximum scale error of 0.05 mL. Graduation increments from 1.0 to 25.0 mL are 0.2 mL, with a maximum scale error of 0.1 mL.
