Precise Control:Motorized pipettes allow for highly precise volume adjustment and transfer, especially for transferring small volumes of liquid, with greater accuracy than manual pipettes, reducing human error. Flexible Adjustment:The aspiration and dispensing speed could be easily adjusted through the speed adjustment wheel. At maximum motor speed, the pipette filling machine can fill 50 ml of liquid in 10 s. 0.45um Hydrophobic Filter:The electric pipette adopts 0.45 micron hydrophobic filter membrane inside. he safety valve and hydrophobic membrane filter provide double protection and can effectively prevent the liquid from being sucked into the instrument and causing damage. High Strength Material:Safety circuitry prevents overcharging and and over-discharge of the battery to enable long life time. Charge for 2-3 hours and work intermittently for more than 8 hours. The shell is made of high strength ASA and PC. Wide Compatibility:Please recharge it firstly after you receive it or it suddenly does not have enough power, when the battery capacity level become low, the pump could not work normally;Compatible with most of the plastic and glass pipettes from 0.1-100ml.
