Serological pipettes, also called disposable pipettes, are mainly used to accurately measure a certain volume of liquid, due to the irreplaceable role in the aseptic removal of serum culture medium, known as serological pipettes, the use of which needs to be used with a pipette, is one of the most common instruments in the laboratory, and is widely used in the field of cell culture, bacteriology, clinical and scientific research. According to the range, serological pipettes are mainly divided into 1mL, 2mL, 5mL, 10mL, 25mL, 50mL six models, 100mL large-range serological pipettes in the market is relatively rare. Advantage: • Rising and falling double-direction scale design, well meet the requirements of suction and discharge. • Clear and concise scale is more convenient for accurate reading of liquid. • Negative scale for extra volume is more convenient to use. • The nozzles of the pipes are equipped with uniquely designed cartridge filter plugs, which can prevent the liquid from being sucked backward and overflowing. • Pipe nozzles with international color codes for easy differentiation and accessibility. • Pipette nozzles are designed to fit most pipettes on the market. • Smooth pipe wall, reduce liquid adhesion, improve the accuracy of sampling. • Accuracy error ±2%.
