Serological pipettes are designed for accurate and rapid fluid dispensing. Sterile serological pipettes are pyrogen-free and PE filter plugged for a variety of liquid handling applications. The sharp, black, highly legible permanent graduations prevent ambiguity and guarantee precise reading and accurate dispensing to ±2%. Made of transparent medical-grade polystyrene, they are sterilized by gamma irradiation. Serological pipettes are tested for endotoxins (0.005 EU/ml), cytotoxicity (ISO 10993-5), and are guaranteed non-haemolytic.
