The design of the pipette is crucial for both precision and comfort. The center of the large size of the pipette button and back suction head key is set separately, so that whether you are right-handed or left-handed, the real realization of one handed operation is very convenient. The whole pipette can be sterilized at 121 ℃ for 20 minutes without disassembly, which meets the requirements of multiple experiments. In addition, the capacity positioning protection device can prevent accidental overflow and ensure experimental accuracy. The four digit volume display is easy to read and more accurate, and the easy calibration technology - quick calibration without any tools can clearly show whether the factory settings have been adjusted. Finally, the short stroke of 12.5 mm piston can reduce limb strain. All in all, this pipette is designed for both precision and comfort.
