Argos Technologies P0900 Plastic Pasteur Pipettes, 9" (230mm), are produced from medical-grade polystyrene in a class 100, 000 cleanroom. Plastic Pasteur pipettes offer the aspirating precision of glass, and the safety and benefits of plastic. Plastic construction allows the long flexible stem to be bent to draw liquid from narrow or small volume tubes. These pipettes can be used with aspirating bulbs or vacuum applications to remove liquid waste from flasks, dishes, plates, and tubes. Pipettes are available in two sizes and are supplied individually wrapped to maintain sterility. They are gamma irradiated, DNase/Raze-free, and non pyrogenic.
