Single channel pipettes are the ideal ergonomic choice for users who need a comprehensive range of automated liquid handling functions. An easy-to-read display and simple-to-operate keypad allows fast recall and setup of user-defined pipetting protocols and selection of operating modes, volumes and speeds. Fully electronic operation maximizes pipetting efficiency for tasks like multiple dispensing, pipetting, reverse pipetting, mixing, serial diluting and automatic sequential dispensing. Color-coded left-handed model. These models require a power supply unit (sold separately) to recharge the pipette's battery. Accuracy: +/-0.8 percent at 125 microliter, +/-0.8 percent at 62.5 microliter and +/-2.9 percent at 12.5 microliter. Precision: 0.15 percent at 125 microliter, 0.24 percent at 62.5 microliter and 1.00 percent at 12.5 microliter.
