also referred to as Pasteur or teat pipettes, these disposable, plastic devices transfer compact amounts of liquid with no danger of cross-contamination. Transfer pipettes, including Corning's Falcon® Transfer Pipets or Gosselin™ Transfer Pipets might have graduated or sleek barrels and are utilized for rough measurements.

Transfer Pipettes/Pasteur Pipettes transfer little portions of liquids. Plastic bulb pipettes are typically not exact enough for use for correct measurements but their glass counterparts is usually really exact.
