Allows convenient aspiration from tubes, flasks, and bottles. A relaxed grip design, low weight, and electronic operations make repetitive pipetting effortless, even over prolonged periods. Ovation also keeps lab work productive with fast setup and recall of user-defined protocols for pipetting, mixing, serial diluting, or repeat dispensing. When extra length is needed to reach the bottom of tall vessels, this pipette can accommodate the use of glass or plastic serological pipets. This model requires a power supply unit (sold separately) to recharge the pipette's battery.
