These pipettes are suitable for use with standard rubber bulbs or, more preferably, specialized pipet fillers, and they are designed to be used in conjunction with lab glassware, often used for scientific research, chemistry, or quality control. They are considered "To Deliver" (TD), meaning the last drop should not be blown out, as it is factored into the calibration.
