Transfer pipets are plastic and offered in both graduated and ungraduated formats with integral bulbs or accessory bulbs for transferring liquids. Graduated transfer pipets allow easy viewing and volume indication. While useful for dispensing measured volumes, transfer pipets are not considered precision instruments. Thermo Scientific™ Samco™ Special Purpose Transfer Pipettes are optimal for dispensing droplets of samples onto tiles or slides. This pipet's single-unit design features a built-in pipette bulb.
