Completely control the small quantity of liquid being manually dispensed with the Pasteur and transfer pipettes. The all-in-one devices are inert to most fluids for maximum working flexibility. Squeezing the small or large bulb, releases homogeneous droplets from the transparent, narrow stems that may come graduated for precise biological spotting or filling applications. Due to the challenge of properly washing the bulb, Pasteur and transfer pipettes are available in disposable as well as reusable models.
