Features: The Electric Pipette Controller features wide 0.1-100ml range with double drainage structure, enabling rapid 25mL liquid discharge in 5seconds via 6speed mode – great for precisely lab work. Equipped with digital LCD screen for real time battery monitoring and adjustable speed setting, this 4800mAh battery powered device supports 8hour intermittent use and 2-3hours continuously operating per charge. Suitable for laboratory professional, and STEM educators requires professional liquid handling across test tube, pipettes, and pasteur flasks in controlled environment. Optimized for biosafety cabinets, labs, and academic setting where sterile liquid transfers between containers demand both speed (dynamic drainage) and contamination prevention (0.45μm hydrophobic filter). The ABS constructed base with slip resistant stand ensures stable workstation organization while protecting surfaces from biological exposure during prolonged pipetting task.
